This is crazy. We're doing this all wrong. We're uh, we're condemning an engine, throwing a part at it, cleaning things, ignoring the leak, and then doing the test drive opening. Z Hood Oh, look who that guy is.

Howdy Folks Good day to you and welcome back! Glad you guys are here! We have ourselves a Chrysler Miniature Van product customer. States Uh. Vehicle has a misfire and a check engine light and it appears that the misfire is only on Startup So we're here with the scan tool. This thing has been parked over the weekend.

It has not start or run. She's got 111 000 I'm sorry 112 524 miles on the odometer. Uh, what we're gonna do here is we're gonna go ahead and connect our scanning device. We're gonna key the thing on, not starting the engine.

Then we're going to go ahead and pull the trouble codes. We're going to document what's in there. We're going to pull up the misfire counts if we can, and I'm going to go ahead and do a cold start on this and we're going to take a look for. Uh, for a misfire on cold Star only.

By the way, this is a 2017 Chrysler Miniature van. I Believe it's got the penta. The star 3-6 sure does. Alrighty.

So from my preliminary information that I've gotten from my customer, they said that it's a cylinder number three misfire. Uh, it's tough to see behind this big tube thing. We've got one coil here, one here, and one here. So that's going to be cylinder one, one, two, three, four five, and six.

So that's one, three, and five out back. and instead, number three was misfiring now. I Don't see a, uh, a replacement coil on number three. but I do see what looks like a replacement coil on number one.

So what we're gonna do is stick with the plan. I'm gonna go ahead and take that information into consideration, but we're gonna go ahead and bust off that scanner, get her connected, plugged up, powered on, and then we're gonna do our own diagnosis because I don't want to perform repairs off of somebody else's diagnosis. Uh, not to say I don't believe them. but we always trust and verify So that's what we're gonna do right about now is verify the situation and then go from there powering on me.

Let's get this guy fired up. We're gonna go ahead and key it on, not starting Z engine. so I'm not touching the brake pedal. Two clicks with our button right there.

It's a keyless system. leave that on the dash so our Ecms and accessories are all powered up. Let's go ahead and close the door so that Ding-A-Ling stops. We'll shut off our climate control so we don't drain our battery.

How do I turn this off? Oh, there we go And we wait. Come on. Scanner waiting, waiting, waiting. All right.

Scan Tool confirms 2017. Oh it's a Pacifica I Thought it was like a Town and Country shows what I know 2017 Pacifica with 112 524 miles display all fitted systems. Dude, let's go into Engine Systems That's going to be where our misfires are found. We do have a check engine light on, but our engine's not running so let's go ahead and pull our codes, codes, menu and P303 cylinder number three misfire.

That's a confirm on our trouble code. Uh, just for fun, let's hit the what did everybody else do to repair this button? That's that little check engine with a microscope or a magnifying glass. Rather, there we go and it's going to tell us people installed spark plugs, They installed coils. Somebody's going to say they put an engine in it waiting downloading content for this vehicle downloading downloading.

Please tell me. Come on. Yep, there we go. All right.

So our top two is going to be the yellow and the blue. The blue says change coil or I'm sorry. The blue says change spark plugs. The yellow says replace coil I Understand that's already been done so we're looking for Next on our list was intake gaskets, intake manifold, gaskets, fuel injectors last and then somebody put a cylinder head in it once upon a time.

So as my customer said, they've already replaced the ignition. or maybe they replaced it. or maybe they moved it around the coil and the plugs have already been replaced so we can maybe assume it's not the plug. However, we're going to go in there and check that once we can verify that there is in fact an active misfire.

I Need to pull the plug anyway I Want to see if there's coolant on the plug or if uh, if any other thing is or anything else is going on with it? Maybe the gap's not right? Who knows. So let's go into not clear data engine data. We want to see misfire data. Then we're going to go ahead and start this engine.

I backed out I was in the wrong menu. Presser made it kind of simple. Look which cylinder is misfiring? Wow, they couldn't have called it misfire data. They had to dumb that one down.

Which one's misfiring with a question mark? Okay So we've got. We've got all our counters pulled up now. Obviously we see zeros here because the engine is not running. but I'm gonna scroll this down some.

so we get all six cylinders and scroll down three times actually and foot on our break. Let us stop these engine. Push the button. beginning.

engine stops in sequence. now and there we go. Misfires Cylinder number three. See that right there? That's all we got misfire on Startup There's one on number one.

Let's give them some throttle. Yep, a bunch of misfires on three. Okay, let's shut her down. So what? I Want to do since we know and we have confirmed we have misfires on three.

I'm going to go ahead right now and we're going to pull that plug and we're going to pull out that coil. Uh, my customer states that this has already been done, but I'm gonna do it again because we need to be thorough. So identifying our correct cylinders, we've got bank one on this side that's the rear side and Bank two over here. On this side, we need to get back to cylinder three, which is the center spark plug coil in between the two flanking coils.

and we're gonna pop that guy out. And then we're going to pop the plug out of it and just take a peek at what's going on with that smart plug here. Let's get this little hose business out of our way. Oh, don't drop that.

Let's get this hose out of our way. So I can kind of reach back there a little better and then you get to work on these plugs and whatnot here. Uh, how does that guy come out? Does it go in or does it go out? Pocket driver to the rescue, push our little clip back there we go and we can, uh, get this connector unconnected there? She is that back in there so it doesn't get lost now. I Think I can reach I Might just pull this whole unit out of here.

Tell you the truth. Yeah, that's probably gonna be best. Okay, another connector over here on our left. let me pop this guy out and then we'll pull.

uh pull this whole little tube looking deal free from its position. It just. uh. steak down with some grommets.

shouldn't be a too much of an event here. Come out little clip. I think I'm supposed to actually push these clips down towards me, but it's not. They don't want to do that.

so I'm just going to remove them entirely and I'll just put them back I don't know why I can't uh, can't get the thing to release like I think it's designed to release? maybe I don't have the Chrysler touch. That's what it is. It's a made of alien technology. There we go, it's loose.

now. pull that guy out, come off connector and that should just be able to pull this tube looking deal off of. uh, all the grommets that secure it. There's one, two and then last one right there.

Okay, now we can see what we're trying to see here and what we're trying to see is Ignition Coil number three. That's this guy right here now. Like I said I Understand these have been swapped out before and their positions have been changed. but that does not mean much when we're trying to be, uh, thorough in our diagnosis here.

So we're basically going to redo what we've heard has already been done. Never know. Okay, the boot looks good. There's no oil and stuff in there.

It's a good sign. So there's our number three coil. Let's go down in the hole here and fetch our spark plug. We're gonna see what that thing's looking like.

the spark plug socket coming in down there all the way in there and we'll go ahead and crack this guy loose and see what we've got to work with on kicks. I Don't know, that's that's kind of tight. okay, feels kind of gritty on those threads. Maybe my guy pulled the the wrong plug out.

Maybe they thought this was a number three up here in the front and it turned out it's the one in the back could be I don't know. There we go now. we got some speed going here. Let's lose our ratchet.

not literally. come on, let's spark and plug. show me what you're working with here. Survey says what is this? A little moist.

okay okey-dokes there's our coil and it does look a little wet right there. I think I think that's gasoline on that coil. It smells like gas. see there's some liquid right there.

I think I Don't think our our spark plug is the issue I said coil I Don't think our plug's the issue I Think that's just a symptom rather than a cause. Um I Do understand that that coil has been swapped from side to side with another coil. I'm going to change that one's position anyway just to, uh, just to make sure and cover all the bases. and then I'm going to go ahead and suspect we've got a faulty fuel injector.

I Believe that injector is probably leaking down. Pull this guy out real quick. Come here. Coil: I Believe this is cylinder Five.

Let's pop this one out and see what cylinder 5 looks like. All right. Cylinder Five spark plug is now coming out. Unclick that one.

Let's pull this guy out, see what we've got going on. We're going to compare the two and I see no liquid on this spark plug? So we had some liquid saturation on number three and not so much on number five. Actually, none at all. Number five and I can still see some gasoline right in here and it definitely smells like gas.

You can see the sheen of it on the back side of this electrode. See that? So okay. I I Do believe we have gas entering that cylinder, but where's it coming from? Alrighty. I've got a boroscope here.

There's our scope and we're going to run this scope down in to the hole here and we're just going to take a look down inside of that spark plug hole. This is cylinder three and we want to see what kind of fuel saturation we might have down inside of there. and bear with me here. while I get it in almost tips a little a little off center there.

bear with me There we go. Going in, let's see what we got here. that's a that's a lot of wetness down inside of there for sure. it's getting a little closer.

See what we get? I'm pretty sure that's fuel. A little bit of carbon on there. I Can't really see the cylinder walls though. Let's move over to number five.

Let's see if that one looks any different. Check: Uh, yeah, we do have some carbon, but look there, there's some dry patches here. See that? So we do have a bunch of dry area inside of this piston. So that's cylinder Five.

It's back out again. Go into cylinder three, check inside of there one more time again. for comparison purposes. Get in there and that one seems to have no dry areas.

See that? Okay, so I'm fairly certain that that, uh, that position is in fact fuel saturated. I Don't believe it's coolant because our coolant level is not low. So I'm gonna go ahead based off the knowledge that I've got here and assume that we have a leaking fuel injector on on that particular cylinder. So what we're going to do next: I'm going to go ahead and put our plugs back in.

So this is the plug from number five. Drop that guy down and we're gonna put the coil for number five in this exact same position right here. Okay, go ahead and get that guy tightened down, Then we'll drop in number five. and then of course, get the uh, the coils in position now.

I'm not going to get the poles backwards because the number five coil is still attached to the wiring harness. so I have to detach that one and then move it over once these things go back in. Oh, you know what? let me undo that real quick before we do this. Let's uh, let's get a quick compression test on cylinder three.

I Think it's okay because uh, it does seem to run off normally. but I would like to just, uh, grab some figures on that that thing's compression just to make sure. who knows I could be wrong and it could have like a broken ring or something. So let's get this guy tight.

screw her down. So this is spark plug number three back in the number five hole. Okay, then we're gonna put the number three coil on the number five hole. so all of the ignition components for three will be on five and all the ones on five will be in three.

and that's going to introduce a variable. Get that guy tight kick. Oh no. I kept my my socket there.

We go. Okay, here's our coil number three coming in. Let's drop this guy down. Like so we'll screw it down quarter inch coming in.

Click itch. There we go. And now we can plug in that replacement coil by disconnecting our current number five coil. Pull that guy back and we can plug her in right down here with the click.

Okay, I'm moving on over to our cabinet. Let's find the compression tester. Why is the that's fuel pressure. What's that thing doing out anyway? Uh, Compression Tester Compression tester Red Box Red Box There it is in the back I See you Redbox There she is.

So what we're going to do is we're going to get our adapter screwed down into our cylinder number three. We'll connect our gauge to it and then we're gonna hop inside and crank the engine to. uh, get a reading on the pressure on cylinder number three right here. Now, we're not going to allow the engine to start and I can achieve that by disconnecting I Believe it's the ASD relay on these Chryslers and that will shut down all the systems that support the engine running.

Come here connector. Come here. Stop it. Oh, this is too stiff.

It's flopping around everywhere. I Might need to handle this one with two hands here. Lug it in there. we go.

All right, that's connected. All right. Getting into our power distribution block here, we're looking for our relays I don't know if you can see it. Starter: ASD We might be able to get with our ASD relay start Run Stop Power Steering Yeah, let's pull ASD That one should shut that thing down.

K2 Is this one right here? Which is this one right here? Set you aside. Okay, let's hop back into the cabin. The engine should crank and it should not start at this time. So foot on the brake.

if it does want to start. I'll shut it down real quick. But let's go ahead and begin engine starting. and it did not start, but it did print.

So we should have gotten some pressure compression readings on. Uh oh, we have no compression I didn't expect that to happen. Hang on here. let's try that again.

Yeah, we're cranking. Yeah, no no no no no no, that can't be right. There's no way we have zero compression on number three. It's not okay.

All righty. So I went ahead and took the uh, the Schrader valve core out of, uh, my adapter. Right here. there's our tool I pulled the core out of it and I did that just to remove any potential restriction.

Maybe that core is not opening up. Uh, when pressure is being formed. I Don't know why it wouldn't but it's possible. So I'm just gonna do this without a Schrader valve inside of it and then we're gonna see what it does.

So I think I'm gonna put you guys over here and you watch the gauge. I'm gonna go run inside and hit the key one more time. You let me know if we get compression. Okay, I'll put this right here with you guys.

Stay. it's not working. Totally not working there. We'll do that all right.

It does make pressure. Okay, that's odd. I wonder why the gauge did not give me any pressure. when uh, core was in no matter.

I'll change it with another one and see if that works Okay I Put another core back in. There's our adapter that takes this down to 12 millimeter threads. Screw this guy back in one more time. I I Know we keep repeating this, but we need accurate test results.

I'd hate to condemn an engine because my, uh, my gauge was not working. That would be absolutely horrible. So we'll plug this guy back in one more time. There's our gauge.

Let's go. hit the key. Crank the engine. All right.

One of unit is here. she's gonna hop in and, uh, hit the key one more time for us. Just so I can see this from the start. Go ahead darling.

Start the engine. Oh, that's not okay. All right. you can stop.

There you go. Yeah, that's uh, that's not gonna do it. 85 90 pounds that will barely support combustion and it sure is not going to support combustion when, uh, during cranking or at low engine speed. So let's throw some oil in there and do a wet test and then see what happens.

I'll throw a little bit of oil down in that hole. Not enough to hydrolock it, but definitely enough to get some into that combustion chamber. Screw this guy on and we'll do it again. Plug it in.

Okay Crank It Again Yeah, a little bit better, but not so much. All right, we're good. Yep, okay I think this engine is, uh, not okay. But for comparison's sake, we need to take a compression reading off of one other cylinder so it appears I did jump the gun a little bit when I pulled or put that number five back on I'm gonna pull that one out one more time and we're gonna check a uh, the reading on five just to compare, to make sure we're getting proper compression and to make sure that my gauge is not faulty because it already wasn't working once.

So pull this guy out real quick. Bear with me folks I know you guys just saw me do all this, doing it again, but I believe I was uh, on the wrong path there I was jumping the gun thinking uh, there's something common like a fuel injector and it might have been caused by a fuel injector, but you just don't know yet. Let's get this guy out real fast. Plug out compression tester adapter in this is number five.

see how this one comes up on compression. This is a known good cylinder without misfires. Let's plug that guy in and one more time, please start it Okay, Oh yeah, there we go. Yeah, we're definitely low.

Okay I don't like this I Can't like it at all. One more time on number three I'm I'm just not happy with this at all. One more time, please start it. 90 90 pounds, 90 pounds, one more time.

This is number five again. Oh wow, we're just too low. Okay, okay. one more test on cylinder number one.

you guys saw earlier. Number one. Uh, did register a couple misfires. so I really don't see the harm in pulling a little bit more data out of this before we proceed.

I have found that there is a TSB on this for a cylinder head replacement due to burning exhaust valves. However, that TSB did not apply to the number one cylinder. Bank it seemed to have only applied to cylinders two, four, and six, which is the Left Bank So I don't know if that's really going to help us out. It might, it might not.

I'm not certain just yet. but what I'm getting at though is I Don't think that that bulletin actually applies to this car, although it does exhibit the exact same symptoms that may not be an Avenue of repair in this particular case. Yeah, bulletins are like that. They can go.

Hey, we have a problem with the cylinder head, but only if it's bolted on this side of the engine, not the other side. Let's take a quick measurement on cylinder one and then see what we get. Thank you! Yeah, it's similar. Okay So we've got a hundred and 18.

125. Yeah, 118 on this one, 125 and then 90 something on this middle Bank 90's too low I Cannot like it. Okay, let's get this out of here. Okay, I've got all the the plugs back in and again.

I have done the swap from the uh, the number three to number five position just to, uh, continue our original experiment. although that may be a moot point. I'm gonna do it anyway because we still have yet to even run this engine for any period of time and observe. Its Behavior So we're kind of only going off of what we were told and what we think.

so I want to put this thing back together real quick and let's go back inside. restart this unit and uh, give it just a. we'll run it for a little while and observe it and see if we have any other supporting data before we make any final decisions on on what's going to happen regarding the future of this particular. Chrysler Pacifica So let's get all of our clips and stuff back in safety connectors or clip retainers rather.

I Don't know why these need a retainer. They were hard enough to get out without a retainer. We'll go put that on. That's good.

good all that's connected. Very good. All right. let's back it on up.

Some get all the stuff off the engine, let us reconnect our ASD relay. That guy goes right in here. Plug that thing back in. So now the engine should run again.

So let us head back into our cabin, bust out our scanner again, restarts the engine and we can watch. uh, watch our misfires beginning engine stocking sequence. Now she's running and misfires. giving us some throttles man.

I Really see Now it's not here. If we had a bad valve, it should misfire all the time. And I'm not particularly thrilled with the fact that my compression tester did not pick up that low compression at first. I'll tell you what.

I think I think that cylinder 3 is not giving me a misfire at all. We did get one that showed up over here on cylinder one, but I don't think it's got a burnt valve because if it had a burnt valve, it would be doing it consistently at all times. and it's not doing that. uh I think I'm gonna put that fuel injector in it anyway.

You know why? Because it's cheap and it's a great way to come up with processive elimination. So I'm taking this stuff back apart. I'm gonna pry one of those injectors out cylinder number three and I'm going to toss that unit in there I Like I said I I thought that's what it was earlier I know these are super common on these things. I'm gonna I'm gonna go ahead and put this uh cylinder 3 injector in I think I can slip that thing out without pulling everything apart I think I've got to pull the upper intake off, so let's go ahead and get started with that and then we'll go from there.

Oh, the plot thickens since we were running. I See some smoke coming down? See how that smoke right there? There appears to be some kind of a leak down below. Yeah, let's get this upper intake removed and then see what we've got to work with down here. Something else is going on with this.

Okay, so here's what I'm gonna do here: I'm gonna pull this, uh, intake stuff off here. This guy disconnected. Wiggle that out. Then I'm going to remove this, uh, upper manifold.

We're going to see what that oil leaks about while we're here. and then I'm going to throw a fuel injector in this because if it's not a fuel injector, then we need to do some cylinder head work. and I'd rather, just, uh, figure out what else is going on because somebody has been in here pretty deep at some point here. there's a clip missing off of this hose.

I Saw a bolt sticking out sitting on top of the exhaust manifold down below and there's all this smoke and whatnot coming out. So we need to get uh, more information before we keep going here. and what I mean by more information is, figure out where the Smoke's coming from. Come on, come here.

That's off. Good! So I'm starting to see a lot of witness marks on some of these. Fasteners So this intake has, uh, recently or at some point been removed as well I need To see what what our other folks have done here. There is a couple of bolts or there are.

There are a couple bolts for some brackets on the front of this manifold. So we're going to pull those guys out. It's a little hot because there's a coolant line right here. It burnt my thumb.

So take these guys loose and then you need a thinner socket for that one. I'll take these guys loose and then pull these bolts out. Pop this intake off. We need a smaller, thinner ratchet to get that guy my bigger one will not reach.

We'll work it out. it's loose. give it the flangy reach around here. Spin that guy out.

it's a little warm. Too hot. There she is. So I think those are the only two bolts here.

Let's go ahead and start to pull these uh, intake bolts out of this unit and we'll see if she starts to come free. There's a couple wires and connectors that have to go, but preliminarily, I Just want to see what all is in the way and what is not in the way and one more buried right there guy out loosey-goosey Okay, there's some other bracket somewhere hanging on to it. It's not these two. It's got to be one more over here.

Let's get this thing up out, All right. So this device also bolts onto the intake. There's looks like three nuts. Let's get this thing disconnected.

Got a hose attached to it? I Think that's like a coolant line I Don't want to break into that and then one more. see it down there I Can feel it too. Let's get that guy out. Come here.

Uh, it's not lining up no matter. I'll lose the extension I'll just sneak this guy down inside of there. There it is. So now let's pull this thing away from our this is EGR or something.

It's gotta be it's not cooler. Probably should just disconnect that hose. What's the what gives here? No something else is hanging on to this this manifold. Okay, I found it I See what's going on? There's another bracket down here and it was loose.

The nut was not tight, the nut was loose and because of the nut being loose, it allowed everything to move around. yet I thought it was being captured by this EGR thing. So yeah, we got it. I've got it.

I Just had to take that that loose nut off of there. And here is our intake manifold assembly with one more wire hanging us up. Got her okay manifold. I'll set this thing down right over here.

you stay there and let's take a peek at what the deal is with that uh, that oil leak that was going on over here I think it's just yeah that just looks like valve cover, gasket leaking. and there's that bolt down there. you see that is a a random bolt behind. now you can see it there.

she is way down there. Yeah, some random bolt down there. Don't know how that got there but it's back there I don't know if I can fetch that? Need a magnet? Oh there's our uh, there's our intake valves on on our number three cylinder here I wonder if I can see anything worth seeing down in there? Pretty dark, adding some extra light to the subject. uh we can see.

they look okay. but one thing I'm noticing is there's a put some liquid on top of a all those valves there that's got to be unburnt fuel. from the injector, you see the injector nozzle is is right here at the top of this intake runner. just past my finger.

I'm looking at the clean pattern of those two ports. see how one port has, uh, it's nice and shiny in the other? Port not so much. I'm wondering if there's a poor spray pattern. See, we can see this port has been cleaned from the from the fuel and that other Port is cleaned.

This one has pretty much a carboned up black part on the left side, but this one on the right is extra clean. so that does present some extra evidence to my case that this may just be a bad fuel injector. Well, since we're here, I'm going to go ahead and Pop That inject her out I've I ordered one real quick. It's got a plug, two bolts and I can pop the thing out.

so we're just going to go ahead and do that and reassemble it. I may end up going back later to do that. uh, that valve cover gasket. We're going to to figure out this misfire situation first.

So I'm not going to put parts in this in case we have to end up doing some cylinder head work so that can be done at a later time. I mean worst case scenario: if if I'm right on with this injector and that solves the problem, then I just pulled this intake back off and change out the valve cover later. It's not a huge deal. All right.

coming in with a Torx 27 for these. Uh, these two bolts on this fuel rail over here I don't have to pull the entire rail out. we're just going to do these two bolts and then pry the rail up and then pop that injector in and out or out and in or both and then put it all back together. fall Do not drop things into the intake.

three. Oh, those came right out. Look at. that was, uh, no consequence.

it can pop right out of there. It's built fuel everywhere. Well, I'll be okay. Okay, there's one of the injectors and I left the O-ring Down in the Hole by mistake, giving it closer examination see where it appears to be faulty.

No obvious defects to it, but you never know. So so now I will take my new unit nice and clean and we're going to put that down in the hole on our manifold right here. Squeeze that guy down in, wiggle it into position. the gasoline will lubricate everything and we can see that number five injector has its o-ring and the number one injector also still has its o-ring so we can just get these guys lined up.

We'll press everything down. There we go. Felt that one go in. It's good.

Good here. All right, let's get rid of all the fuel that's in here. Hanging out outside with some air. This is shiny.

Okay, right. now. throw that bolt in, connect our connector. Yeah, it's tough to see I know it's dark in there.

Click that on. that's it tight. Okay second: Fastener Coming into the fuel rail torch 30 coming in. let's get these guys tight and we'll throw that intake back on.

I'm probably going to have to let this thing, uh, cold, soak overnight to confirm or, uh, deny or repair on this. So what we're going to do is after: I throw this intake back together. we're gonna take it out on the road. Go ride around, put it through its Paces a little bit and then just make sure that, uh, it doesn't have any other misfires that show up.

uh, after it's warm or after it's under a load. here. before this goes back. I'm gonna hit this with some air and some cleaner one more time.

Inside of all these uh, these valves here. I Just want to break up and remove any carbon deposit that could be built up in places inside of there. I Do see a lot of dirt and nasty going on in these intake. Runners And since this intakes off, we can break, clean those out and get it clean starting with our affected cylinder.

So please be prepared for some loud noises here. Keep in mind most of these valves are all closed, so even if something does go inside of one of the holes, there's a very small chance that it makes its way into the combustion chamber. But we're not going to, uh, rely on hopes and dreams here. and I am going to take some precautions.

just spray some brake clean in there and then toss the towel on it so it doesn't all fly out in our face. We're just going to blast this with some air on the inside. Now these valves are closed and there's some violence going on inside of this. Runner Right now.

I'm gonna prove it. Look at all that nasty yeah chunks. Look at that chunks of carbon on this thing. It's not okay.

watch. Wipe it down that's clean back in the hole. More chunks, more chunks, So gross. They build up on the valves.

Could have caused this for all we know. Much more. better looking. Okay, okay here let's zoom in real quick with a flashlight and see what the difference is.

How we looking. Now that's a little better. I Suppose Okay, let me go ahead and knock his other five cylinders out and then we'll get that intake manifold back on the car here. Alrighty, upper intake coming in.

we've got our bolts in position in the mounts. Let's go ahead and slide that hole over the EGR We can slip this unit down into its position here and get her bolted in. Good. Okay, looking around, our EGR is in position.

with the exception of its nuts. all these bolts appear to be lined up. They're starting to thread by hand. so I'm going to tighten these guys down.

The two bracket bolts up at the front are in position. I've already put that one in right there. and then this one is already in right here. And our little stud below the throttle body that confused me earlier is also inside its little hole.

So let's go ahead and get these. uh, these bolts tightened down. I'm just running them down with the tool right now. I'm gonna apply hand torque in a movement.

They're not all tight yet. Keep in mind these are threaded into plastic, certain that they're easy to strip out, and Destroy which, uh, we don't want to do that. so take away our power tool, bust out the hand tool. Let's get this stuff tight.

All torque specs are predetermined by me. Click. Okay, this one needs a couple turns and we got that one. Let's check these again.

Tight tight. This one over here. get that one tight. This one over here in the back.

Tight. That's good. Okay, and final. Click: All right.

These are all good. Now we need to tighten down the two bolts down here on those large brackets that stabilize this unit. Then we'll get that EGR back together and that other little stud that's under the throttle body. After that, we just have some supporting equipment, little hoses and we'll get this thing, uh, restocked in.

We'll go out and give it a test drive. This is crazy. We're doing this all wrong. We're uh, we're condemning an engine, throwing a part at it, cleaning things, ignoring the leak, and then doing the test drive.

all part of the diagnosis process. It's like inverted diagnosis. completely. doing it all around.

all right. Click on that one. Very good. Let's go ahead and get our EGR bolts.

Nuts Okay, EGR nuts. you're next, and that guy two and then the third one's way down in there somewhere. Okay, Cage got it. Good connectors need to be connected.

That one's on. This one's just kind of hanging out. Uh, what else do we have here? We've got one for throttle body. That one's gonna go on right there and it plugs in here.

we go That's good this guy. I Gotta worry about that guy because we're about this guy. that one goes down there. I Think that's the vacuum booster.

uh, vacuum line I Think plug that in C1 This guy slips into that mount there. plug it into vacuum here. This is for our uh, evaporative emission system. Guys, plug it in right here.

Checkages: I Got that wrong that goes under thin quicker juice because that guy goes right there. Okay, oh no, you guys. my GoPro died from heat exhaustion because it's 97 degrees Under This Hood right here. Anyway, I've got uh I have the Ambi airtep sensor plugged in in the back.

We're on our final nut right here. Foreign. Let's get our little clamp right here, tightened down and then we'll get our cover back. I Truly dislike it when things, uh, don't operate as designed.

Look at all the metal flying out of the bottom of the plants. You guys see that little shards of chunks of metals. Okay, we're down to the odds and ends and some housekeeping duties and this thing will be, uh, will be ready for restart. So let's get our little intake scooped back in.

We've got two bolts for our cover. We'll get that back on in a moment. Let's get uh, important. Otherwise water gets in there and then ruins the battery.

Junction Block happens all the time. Don't pressure wash those right there, Do not. Oh wait, no it doesn't. The Chevy ones say Do not pressure wash with a little pressure washer symbol on it or whatever.

I Guess the Chrysler is a don't bother doing all that snap that line back in that on one more little push button little guy there. that one goes in this one and a little bit of torque action on these guys. Click twice, click and housekeeping and we're ready to rock and roll here. All right, let's get our Hood down.

Safety: Hood Prop removed it came with its own hood prop but I always install mine just in case you never know. Like for example: look at this one right here. that one's broken. so I don't want to hang my light bars and whatnot over my Noggin I potentially faulty inoperative Hood Prop: because of safety.

So here's the deal. We're gonna hop in. We're gonna pull the scan tool back up, restart the engine. Uh, there's a chance we're gonna see some misfires.

Uh, right from the get-go simply because I had a bunch of spray and whatnot down inside of this engine and that they should clear up very quickly and then we can let this thing come up to temp and then, uh, the road. Okay, windows up. We're powered on reestablishing connection and communication. our dongle still plugged in misfire monitor beginning engine starting sequence now and she is alive.

So far so good. Come on. AC We need some climate control in here. All right, So we're still looking at a bunch of zeros on these misfire accounts.

Let's go ahead, get this thing in Drive Let's go go out and hit the road real quick. Take it for a spin over the bridge, around the block, over around and through, and then, uh, we'll see how this thing runs after it's uh, reached operating temperature and has a load on it. Mmm. traffic's clear.

let's go go so far. she feels good. So again, the reason I didn't touch that valve cover that leaks just yet and I know I was right there and it could have been a very easy repair. The reason I did not touch.

that is because if we have to go deeper into this engine like uh, pulling the cylinder head off for example, I didn't want to go ahead and go through all that, change the gasket and then have to go through all that again and then change the gasket again. So I figured I could save that until later. but I needed to have some some preliminary results first and I figured the best way to do that was using process of elimination. I got rid of that fuel injector that could have been suspect it.

it may might have been fine and I'm off base and it wasn't an injector. but since I felt like my compression test results were somewhat inconclusive I didn't want to just go. hey, there's a bulletin on the other cylinder head, so we need to just replace this cylinder head because that just wouldn't have been fair and I'd rather have uh I'd rather take the extra time and do a little bit extra work to have the exact diagnosis rather than uh, going with what it probably could have been. Okay, so that car behind me was doing a U-turn in the middle of the road intersection back there and I'm afraid of that car and I'm not going to pull out front of this guy either just because the car was doing something.

I'll make them wait. What's up control? You know as soon as this little S10 goes by. hello two-door Blazer Nope, you changed lanes. You suck.

All right. we're on the way we're in. The throttle engine feels good and strong I'm not feeling any kind of pulsating or uh, or surging action. No misfires according to the scan tool, so it feels good.

but we don't know for certain because the symptom was on cold start. So what we're going to have to do here is, uh, pretty much let this thing cool down overnight and then recheck it in the morning. So what I'm going to do I think is since preliminarily we're looking good, uh, I'll just do a quick follow-up video on whether or not this thing has a cold start misfire that's going to actually end up being posted I'll do it tomorrow morning, but I'm going to post that on uh Rainman off duty, not on this channel the primary channel. it's going to go on the second Channel because it's just going to be a real quick, like two minute video.

So that being said, go ahead and look out for that second one on the second Channel Again, that's Rain Man off duty and uh, you'll be able to find the uh, the follow-up on this misfire at that point in time. As of right now, though, we have no misfires on uh, on cylinder three. So all that being said, I think we're kind of in good shape right now. Um, time is going to have to do its thing before we can actually finalize the diagnosis on this.

So that being said, I'm going to go ahead right now and close this video out I'll do that as always by thanking each and every one of you guys for watching this video as always I Hope you enjoyed this video.
