Customer Customer States Mechanic Fails Engine Transmission Gas Diesel off road race 4x4 street car daily driver scam dealership dealer technician how to
Hi everybody, Good day to you! Welcome back! Uh, we are actually returning to a second video on this 2015 Cadillac SRX Dash 4. Meaning she's the all-wheel drive version of the Cataract It's got a 3.6 Liter V6 engine. she has approximately I don't even know where's our mileage at With approximately 86 432 miles on the odometer restartings the engine all right now, we got all that good stuff out of the way. Uh, the reason for the second video is because, uh, they wanted me to perform an intake slash uh valve slash fuel system slash induction Cleaning Service uh on this uh particular.
Cadillac So you'll notice we've already got the engine cover back off of it I Pulled up some of the coverings here and I've got a hold of the air intake tubing where we exposed the air filter element the back side of the mass airflow sensor. and then we've got this weird goofy little hose running into an IV bottle going into the intake screen. All right. coming on in for a better view here.
let me pull this apparatus out real fast. You can see it's got this uh, nozzle on the end here. That nozzle is going to spray a fine mist of a cleaning solution into this intake ducting. It's going to do that past the mass airflow sensor.
That way it doesn't contaminate or potentially damage the sensor. So what we're going to do here is we're going to fill this vessel with some cleaner solution. We're going to apply shop air to it to pressurize it. There's the air.
There's our regulator. so we're gonna have 90 pounds coming in and I don't know what? 10 20, 30 I forget what it's set at but a lower pressure going out. It's going to spray that chemical through the engine, through the intake tube, over the throttle plates, into the intake, Runners over the valves and then into the combustion chamber, thus cleaning out the intake side of the engine at the same time. I've got another can of cleaner.
it's called the 44k got sponsored. That's just what I sell and what I use and this is going to go into the fuel tank. It's a concentrated cleaner and that is going to be pumped through the injectors to help clean out the inside of the injectors. So it's an air and fuel system induction cleaning service.
That's what we're going to do today. so stay tuned because this is going to be a very good video now. One of the things we're going to need here is going to be a throttle stop. This little hook right there hooks onto the steering wheel.
Then this Rod extends and pushes down onto the accelerator pedal and we're going to use that to hold the throttle slightly open in order to generate some more airflow into the engine to help pass the cleaner. So we hooked that guy on right there. push the rod down, contact the gas slash accelerator pedal. Then what we can do is turn the knob, it's going to extend it and Then give us an increase in throttle.
We're about 1100. I'm going to run it up maybe 15 to 1800. All right. I Think we're good here at about 1800. RPM So let's hop on out. Let this thing. uh, we need to go ahead and fetch our first stage of cleaning solution here. Pop the top here.
There we go one-handed We'll refill the vessel and then prepare for the cleaner. injection pouring things, spilling things, filling things that I'm pouring. Now, when this thing starts to feed in the cleaner, it may or may not drop engine RPM down and it also may or may not cause misfires. So we're finished here.
We're going to have to, uh, check for any trouble codes before we release the vehicle. All right, the valve is off. That's the 90 degree position on the valve handle, so that's the off position. Let's go ahead and connect Shop Air to it and then, uh, just to send the cleaner on in.
There There we go. Okay, so we're regulated at uh, what about 45? 46 PSI on the output. Let's go ahead and open up our valve, send it. Okay, so it is now injecting the cleaning solution.
Let's go back under and into there we go. Let's take a look in there, see it in action. Yeah, see that, let that ride all right now. You might think this is like a set it in, forget it kind of situation, but it's not.
See what we need to do is come in here and give this a quick Full Throttle blurp a couple times as we break our tool right there. That was fun. Anyway, we're gonna give it some quick full throttles. That way you get a good ingestion of all that mist and if any of it, any of it starts to build up inside of the intake somewhere.
it'll help suction that out and then we'll set it back to our 1800. RPM and Let It Go All right, we're back out checking on the progress of our bottle. We're about 30 percent complete on the service, so we're gonna let this go for a little longer. Engine RPM has been bumped up to like 2 000.
wide open throttle back at idle. wide open throttle packet item. Now these fly by wire cars. they uh, if you hold the throttle down like if I go if I go Full Throttle ahead and hold it.
Look what it does. It only gives us the maximum of like 3 100 RPM so we can't Redline the thing through the moon and blow it up. It's all in the programming. If This Were Like A carbureted car or an older generation fuel injection car.
The thing would just be like 8 000 in Peg and that would explode. Maybe not, but it would probably get a valve float before it exploded. But you never know. and again, we just repeat this process until our bottle is empty.
Okay, so while this thing is, uh, settling in one more time, let's go grab a funnel and we can get uh, that other can installed into the uh, the fuel tank. Let's see here. Open sesame. Yes, that's reckless.
Hey, it worked though. Look, check it out. it may be Reckless but it was fun while I was doing it. that's why I did it since the chicks dig it.
There we go stanky stuff. So this part's gonna be real easy to describe the canned funnel. It slips over the can like so and then we'll just stick it right in the fuel tank. so let's see what do we have, Get on there. Oh good. These don't work so well with the capless tanks. The capless, uh, fuel tanks tend to uh, have like a little overflow and it will dump out all the cleaning solution like right here through the wheel. Well that's not okay.
now. look. I spilled some on the paint Corey It's not gonna hurt it. Watch.
take a towel, wipe it down. You gotta think this paint gets exposed to gasoline and sunlight and there all kinds of stuff. A little bit of cleaner is not going to hurt anything. o-ring looks good.
good. tighten until one click. Got it and I'm pretty sure I'm a little late on the uh, the blocking action. For the naysayers: no, this is not snake oil.
No, you don't have to buy it. It's something that I use and that I sell and it is a product that works. It's not a copy. I mean if it was a product that didn't work, they'd get sued.
I mean BG's it's an American company. They they build their products in-house in the states. It's not. Uh, it's not something that changes hands 10 times and nobody knows who to hold a countable accountable.
Um, it's it's a legitimate product and it exists and people do use it. And that doesn't mean it's for everybody. and some people aren't going to spend money on such maintenance services such as this. and that's fine if that's your prerogative, No problem.
But that doesn't mean you get to come in here and tell me how I'm stealing money from people and selling snake oil. because if that's the case, then we're all stealing money and selling snake oil and the entire system is a farce which I don't believe it is. So so there comment on that. ha ha.
Okay, it looks like our bottle we're about right about there so we're almost complete. I'll let this hang out for a little while. Maybe uh, maybe turn up the juice some see if you can't get some more in there I Want to flood this thing a little bit at low speed and then we'll go ahead and shut it down. Let it sit and cool off because any carbon and varnish is filled up inside of there.
as of right now it's being set. It's saturating and soaking in this cleaner solution. So as this thing cools down, that cleaner can work at that carbon and break it down. Then when we go to restart it and it comes up on another heat cycle, that carbon can be burnt away and then expelled through the exhaust and through the engine.
That's playing. Okay, returning. All right. We're empty.
The vessel is now empty. Let's shut it down, depressurize, and we'll go ahead and shut the engine down. powering off. So as this thing cools down again, it's going to break away.
it's gonna break away some of that carbon buildup. And in the meantime, while it's cooling off, I can go ahead and get my flashlights out of the intake. We can get our little nozzle there. you go out of the intake and put that thing away and we can put all this stuff back together. Okay, let's get that light out. Let's get that light out. Nothing else inside the intake. You can slip our air box back in.
pardon my Noggin There's slots that this thing has to go into, then it slides back and then I can clip it with the clips and it's Hot Hot Hot Hot. I Think there's a third one right over there. there. We go.
Clip on. Got it? So now we'll take our Plastics slide that one back down below. That's what I'm doing here. Yeah I don't know where weird shadows it's getting late in the day the Shadows are cast.
Nobody can see what's going on here. so I better make it snappy. Let's put our Clips back in that Snappy Clips get it Dad joke. Put that one on that.
oh hot flashlight hot. There's our bolt and I'm missing one clip which is right here. push pin installed there. We go.
there. now is the end because the Shadows are so horrendous. Nobody wants to watch this anymore. So let's get our engine cover back on, oil fill cap going on.
and then there's one bolt that secures the cover. That guy in there right here up. right now. there we go and I'm standing out in the sun and I'm like I'm a I'm an UltraViolet magnet right now.
hot. Even at 5 30 it's still hot Florida thing we're near the equator. There we go. Oh and take our little uh, our fluid delivery device.
Put that thing back where it goes as well. Where does it go? I think I choose over here. That's a good spot. It's out of the way.
We'll leave it right there for now. Okay, so it's been about 15 20 minutes. Cool down. Let's go ahead and get this thing restarted.
Put on the brakes, pushing buttons, stopping the engine. Now this is going to do one of two things. It's either going to blow out a bunch of smoke from the tailpipe or it's not and Thor's gonna misfire or it's not I think it's a I don't think we're gonna get the plume of smoke out of this one that it can happen. Nope, that's a negatory not doing it.
No worries. All right, let's get the hood closed and uh, we'll take this thing out on a quick test drive, make sure it's all copacetic, and then we can return it to the owner. goodbye. Cadillac Oh wait wait whoa whoa whoa Nope.
Negative Nope, No, no, can't be doing that I mean you can, but I don't like to I'd rather clean it off there. Where were we? Okay, so here's the deal. back in the cabin. now.
just because it wasn't misfiring and shooting out a bunch of smoke here at idle, that doesn't mean it won't do it while under load. Okay, so we always have to go out on a test drive. One of the worst mistakes that techs can make doing this kind of service is they'll They'll do exactly what I did. They'll think everything's all good and then they'll finish up, pull the thing out and park it. Then the customer comes by to pick it up, Then they go to drive away and they don't make it a block down the road. And if things rolling a bunch of smoke out and misfiring and they go oh my. God you broke my car. what's wrong with it? It wasn't doing this one before I Brought it all right.
We're looking good. Let's get out of here. Spring see I hear some some pinging just a little bit but I heard it ever so slightly. Yep, there's some yeah we need to test drive this and get this thing through a whole RPM range under load to make sure that it doesn't do that while we're driving because technically that could cause or not.
technically it could definitely cause a misfire or a check engine light. Yep, Ting Ting Ting It'll go away soon enough waiting in traffic. Now here's what we're not going to do. We're not going to pull out in front of that guy in the yellow truck.
See, we could have made it. We definitely probably could have made it. But what if the guy in that white truck decided he was going to cut over and then speed up and then I pull out at the same time and then the white truck Slams on the brakes. The next thing you know, the big semi truck rear-ends the guy.
That's how this stuff happens. Then the whole world blames the big truck because somebody else who wasn't even involved that drove away caused the accident. So don't pull it in front of people. Just don't do it.
You can wait. It's not worth your life. Okay, full speed all Steam and brake check. Look, it's a squatted.
Hyundai Looks like the phenomenon is affecting the Hyundais as well. It's like a Zombie Plague for squatted suspension. Don't do that either. Ah Florida That was great.
It's raining on this side of the bridge and not on that side of the bridge. It's fantastic and we're gonna. We're gonna duck this yellow light. Not waiting.
Florida I could do that. All right guys. this thing's good to go. We had no check engine light flash indicating a misfire due to the cleaner.
Again, it would clear up, but if it did show, we'd have to go back in with the scan tool and then clear it out. So that was a successful test drive. We put full engine load on it, it's had its cool down time, there is still the cleaner in the gas tank and again that's going to work its way through the injectors. We have the appropriate amount of fuel for a set cleaner.
I Mean a half a tank is probably best, but I'm cool with that quarter tank as well. So uh, that being said at this point I Think there is nothing more to do here except for to thank each and every one of you guys for watching this video. As always, hope you enjoyed this video. If you did enjoy this video, please feel free to let me know about that in the comment section down below.
Tap that like button while you're down there and most importantly, ever sell is a fantastic day! Thanks for watching. See you guys later in a video in a transmission. End of day? No seriously. back on this side of the bridge, no more rain. Well well never mind Now we have rain I Lied it is back. Rain is back. I Am back and the gates closed. No.
Im partial to the Italian tune up myself 😊
Reeeeeeeeeee snake oil!
Two weeks ago I used SeaFoam on my 2011 Cadillac CTS4 3.6 v6 51 thousand miles sat a long time I got it in 2019 with 18k miles from a family member. I pulled the vacuum line from the brake booster. The process is easy as well
The car smoked white after a restart and now it has a much better throttle response I even noticed a better fuel economy of up to 23 MPG from 15 or 16 MPG.
Isn’t it recommended to change the engine oil at around 1k mi after administering these types of cleaners?
Do a before and after video on this cleaning product if you really stand by it.
Valve cleaning this, ethanol rating that
Man, I really don't miss this crap bahaha
Ray, I’m in Australia, I have a 2014 diesel Nissan D22 Navara, I use an intake cleaner each service and a fuel additive. It’s works great, definitely not snake oil I suppose some people are hard to convince.
When you add the 44k to the tank you must have less than a quarter tank or it is diluted too much😮
BG has a plant in Wichita Kansas i had some friends that used to work there… it works… i have used injection cleaner for years plus the additives in the gas tank
I've used CRC intake and turbo cleaner on mine, but in the end I'll probably just get the valves walnut blasted. I've also got a catch can to (hopefully) remove some of the oil blow by that coats the valves.
Pull the intake manifold off of any direct injected car with over 50k miles and you will see why this is an important service to perform. A direct injected motor has nothing but air and combustion vapors flowing over the valve heads. On an older fuel injected motor there was atomized fuel and air passing over the intake valves that would help keep deposits from forming on top of the valves, this does not happen on direct injected motors and they all develop deposits on top of the intake valves. I have saw Audi V8 motors that have such bad deposits on top of the intake valves that they set misfire codes. The repair for these is to remove the intake manifold and after making sure that cylinders intake valves are closed blasting the intake runner with crushed walnut shells, or some other blasting medium. This will do a very good job of removing these deposits, but you risk debris falling past the intake valves into the cylinder and is a bit of work, which equals a bit of money. Upper induction service should not be overlooked on direct injected motors, but isn't a bad idea on port injected motors either. Make sure you know what you are doing before doing this, we have replaced motors due to inexperienced techs just blasting entire cans of induction cleaner through an engine way too fast. The BG service works very well, though there are other setups that will get the job done as well.
This and top tier fuel without those 5 or 10 percent bioethanol shitty stuff that build up this sludge… (opinion for german conditions)
Had it done and 45K on my 18 Kia soul 1.6l!!
Previous to that I could get as high as 40mpg!
Since the "cleaning" which was 3 weeks ago I haven't achieved 30 mpg but twice !! The second time was yesterday!!! Wasn't worth 422$ paid for it!!!!
BG does make good stuff, some of it can seem iffy, but there's lots of factors involved in the use of their products
Without walnut shells cleaning I’m doubtful this does much.
Why is it the more expensive the car is the more dang covers they put over the engine?! What a waste of material.
Gotta love how BG seems to be everywhere at this point, big fan of using their service tools, when a service is requested, or recommended. (Except the pf5.)
thankyou Ray,for an interesting upload see you in the next one,👍👍
Any idea if that cleaner stuff is safe and effective on rotary engines?
I want some snake oil with close to 300k miles on my car it kinda needs it.
I wonder what that stuff does to the cats…
I use Sea Foam, and it works similarly to the stuff you use.
I use liqui moly additives and i agree good quality additives are not snake oil, i used their engine clean before last oil change, afterwards you could eat ya dinner off the inside of the engine going by the removal of the valve cover (needed new gasket).
Hi Ray, where can I get that bg tool?
I had a throttle body fuel injected car when I was young and stiffy lube sold me on that stuff. Probably not needed in my case. lol
What, no walnut hull blaster? Yeah, I wouldn't mess with that either.
Once a year I remove the intake tube, open the throttle plate, and fill the intake with Amsoil Powerfoam. Put it all back together, ler it soak awhile and start it up. Keeps the intake clean. I also bought a similar apparatus to this on amazon that i connect to the fuel line to clean the injectors. BG works great in it. Its a simple job that helps keep the engine smooth.
yeah many people are stoopid.. snake oil. SeaFoam is snake oil, unless its a dirty carbureted (2 stroke) engine. People also dont understand direct injection or clear coat paint (as a hardened product) vs Lacquer or enamel which hasnt been used on cars since 1996. (Ford being the last to use it on F250 and higher trucks before the government mandated it be discontinued on mass produced vehicles. (doesnt include delivery trucks though like UPS or farm / industrial equipment).
Anyone who has a Direct Gas Injection (DGI) engine should get a Oil Catch Can installed. It will require you to empty about once a month. Then the oil vapor won’t enter intake. And this service won’t be required JLT company makes oil catch cans for many different cars
For those of us without the cool IV bottle tool ….. What are your thoughts on my method of Seafoam through the brake booster vacuum line?
A piller had grease or oil stains.
Every time I've had this done, it kills 1 or more O2 sensors. Normal or just my bad luck?
Walnut blasting is the only way to clean the valves etc. Top tier gas has proper additives to keep injectors clean…
I bought the BG cleaner off of eaby and a cheap amazon injector like the BG one, i did notice a approvement on my truck and wifes car. Just wish i had a BG dealer so i can buy more stuff. I do like it also would like to try the oil stuff too
I wold have more confidence that this treatment works if there was a before and after bore scope of the valves.
😀🤣
All engines benefit from this type of service. Even carbureted engines, GM Top Engine Cleaner has been around since the 70’s and is great for this type of service. Port fuel injection has an issue with buildup on the back of the valve causing rough idle and hesitations due to the carbon acting as a sponge and absorbing fuel then releasing it late in the cycle. We sold induction cleaning as a service since I entered the field in the early 80’s. Makes a world of difference with idle quality on any engine.
Don't forget to occasionally drain your air compressor tank. Prevents tank rot.
Your ability to hold the camera reasonably steady with one hand and do work with your other hand is unusually high.
Yes, entire system is a farce.🤣🤣🤣🤣
the cleaner that you pour the cleaner into needs cleaning before you pour the cleaner into it to clean the intake..
.. 🧐… compressed air fittings..
in the dirt…aahhhhh..😡
DON'T WIPE PAINT WITHOUT LUBRICATION! DON'T! DON'T! DON'T!
Had the same issue. I used Seafoam.
The worst example of this bullshit DI is the 2013 Hyundai 2.4 … Holy shit there was so much carbon buildup and ring blow-by in the end of it's life, this thing needed a quart of oil every 200 miles. There's a class action suit for them too… Hyundai lost their shirts replacing engines in these things
Heya Ray, great video! How often would you recommend GDI cleaner be run through the system?
For a direct injection engine with a turbo, e.g., Subaru 2.4 turbo, how often should this service be done, and should the cleaner be introduced before or after the turbo? The maintenance schedule is silent on this type of service.
If you pulled out that cause a cadillwreck
I deliberately bought a non DI truck and use Techron FI cleaner regularly; can buy a lot of gas for what it costs to fix a clogged up DI engine and don't have to deal with it or worry about it.
why are you blowing exhaust into the shop
SNAKE OIL??? Is that what I should be using to lubricate my serpentine belt? If so, do you recommend changing the blinker fluid and muffler bearing at the same time?
Ray. Is there a reason you can't set engine rpms with the scan tool? I've seen you do that in other videos when troubleshooting stuff.
+1 on BG – especially 44k. I have had amazing results with it over the last 35 years or so.
BG is good stuff I use it myself and have done plenty of those cleanings at a previous job.
There must be a way to disable the soft limiter in neutral or park. For example in certain VW Audi Group cars if not all, to remove the limiter you must disable the ESP.
The workshop I worked before, we used proper diesel. Small water bottle, fill it with diesel, small nozzle on the bottle lid. Does the job perfectly. Bit of white smoke while burning it but that's fine 😅 no need of extra tools haha (that's what you say when you don't have any) 😉
If this is snake oil then explain how intake cleaner removes the carbon from throttle bodies. The stuff works when user correctly
Poor Troy had to work in all that exhaust from the Cadillac.
on the BG stuff.
i've used the BG products.
we did the trans, power steering, engine flush, throttle body, decarb & 44k services.
i've seen the 44k clear up misfires on the GM CPI systems in minutes during 1 treatment. using only the 44k in the gas tank had cold start problems taken care of, even on GM TBI.
the decarb treatment like Ray did here, works great. ford triton needing spark plugs? the shop i was at it did not happen without a BG decarb. we seldom ever broke a spark plug. when we did have a plug problem, we had the kit and the repair wasn't too bad. we also repaired a fair number from other places and some of those,….
i've used BG on my stuff, i no longer have a hookup so im stuck being on the other side of the counter which is a hard thing to do.
former ASE master+L1.
Could potentially dislodged carbon damage the turbo, if so equipped?
Another fantastic video Ray!
Mr. Ray would it be possible to obtain 2 SEMA passes from you sir? I’m 71 years old never been to SEMA and would love to go and take my high school friend with me. We both went to trade school together for automotive in Cleveland Ohio (Max Hayes trade school). We were both in the top of our class. The passes wouldn’t go to waste. Thank you.
What does all of the loosened up carbon and junk do the catalytic converter?
Before the ethanol in our fuel it wasn't as bad but ethanol gums injectors and creates more carbon build up twenty years ago wouldn't have worried. Did a similar service on my wife's crv and there is a definite performance change and a 8 mpg increase on mileage
If you do not do this type of service on direct injection gas engines you will pay for that service cost many more times over in other extensive repair costs etc.
I'm from Queensland, Australia, does the same thing.
Black color there reminds me of the older Cadaverlacs of years past!
i worry about the cats with that system
I like to use my scantool to set the RPM. It will pull it up when the engine bogs.
Can anyone tell me what brand or part number that tool is that he used to clean the system? Edit: i found out its a bg via but cant find anywhere to purchase it?
It still worries me that you still drive one handed. This time in a customers car. In the rain.
that happened to me after picking my car up at the mechaic, it started running really rough and stumbling. Called him and he said no it'll be fine once it gets it out of ti's system. was kind of nervius driving it, afraid it'd die on me or something but after about 10 minutes it did clear up and ran good again
First off I want to say that I'm NOT knocking this particular cleaning service!!!! I do NOT have any experience with it. I'm NOT saying that any of these types of cleaning services are "snake oil"!!
Now having said that. I do have experience with several others. Which will remain nameless. Just in case there's any folks here that happen to use them. I'm not trying to pick an argument with this!!
Several years ago I had the opportunity to actually see what a couple of these FIT's (fuel injection treatment) or FIC's (fuel injection cleaner) do. I was able to look and see before and after. All the before inspections were done via a camera. After inspections were done via camera and engine teardown (because I was rebuilding them). Now the one I did the most testing on was my own engine.* MY results were as follows.
It basically boils down to how the cleaners were introduced to the system. A true "injector" cleaner goes through the actual injector. Meaning that you disarm the fuel pump and run the engine off the cleaner. Afterwards, the intake runners were VERY clean directly under the injector and tapered off in a teardrop the closer it got to the valves. There was a noticeable difference to the top of the intake valve after the service. Only a slight, if any, difference in he combustion chamber and top of the piston.
"Intake cleaning" services were different from "Injector cleaning" services. Although the two I tested DID have an additive that was added to the fuel. Which imho would make them a combo cleaner. But whatever. There was a noticeable difference between the two. Neither of these were "off the shelf" systems. Both required some sort of specific delivery system. In both cases a vacuum canister with adjustable delivery rates. One seemed to be worthless. I saw virtually no difference from before and after. Whereas the other seemed to do a perry ok job. After the cooldown period, there was a lot of exhaust smoke as well as P0300. Which all cleaned up within a couple minutes. There was a noticeable difference in the upper and lower intake plenums'. Although the cleaning did tend to taper off the closer you got the valve. I did see a noticeable difference in the combustion chambers as well as the top of the piston.
Now in all fairness. I've no idea how these effected fuel economy, if at all. I wasn't looking for those results. I was strictly looking at how much, if any, these systems cleaned and where exactly the cleaning took place. I am an independent mechanic who's not affiliated with any of the brands or company's. I simply wanted to see an apples to apples comparison of just how effective these cleaning systems work, if at all, for myself.
So in closing, My advice is to make sure you're buying, or selling, the correct service needed. Either a true "injector only" service or a "intake cleaning" service or a "injector and intake cleaning" service. Because they are different and each product produced different results. So sell your customers what they need, NOT necessarily what they want. Once the differences are explained they'll appreciate your efforts. Personally, there's systems out there that are great and there's ones that well….not so much. I think that's a decision y'all need to make on your own for what's best for you and your customers. Personally, there's systems out there I wouldn't let near mine or my customers vehicles. Most are vacuum delivered. This opinion is based on what I'VE seen. I think I'd like to see a before and after teardown of this particular systems. NOT because I think anything negative about it. But because it would give me the best information to make the decision to whereas if it's good for my customers.
Your doing a great job Ray!!! I do admire your work and ethics!!!
Y'all be safe out there!! Stay cool, it's F'ING HOT out here in E. Texas!!!
*Although the brand and whatnot aren't really important. I'm sure there's someone who will say my personal results are worthless. Simply because I didn't use the engine out of a 2012 "Inferno Orange COPO Camaro………..Convertible!" (They ONLY built 20, give me a break…… I was on a budget. Geez) Although you don't want to do anything like this cleaning thing on that car anyway, it's supercharged. 😉
More snake oil…
Love learning from you.
The other day you showed me how to check the multimeter resistance by putting the prongs together and when it made a sound we new that the multimeter resistance working. You know what I mean.
Please if you can continue teaching how to use scanners and etc etc. I know that it's hard especially when holding a camera.
Love your show.
Only thing I see wrong is the car should’ve been exhaust outside shop
Why do mechanics put paper floor mats in the customer's car. But put there grease hands all over the steering wheel. Where's the gloves?😢
Ok, i agree that this is a must. So, where do i GET said tool???
The tool in the intake was sure leaking a lot….
This doesn’t foul the plugs?
IMO if I wanted to perform that cleaning service I would find a product in a spray can & perform it in my driveway hence making it cheaper.
Not needed for non gdi. Just clean throttle body.
Ahhh just remind me to turn in my yellow stickers for some cash hahah
Just saying it sounds like how old work trucks that ran on propane when you did take them apart they we clean as hell 300k pull the intake and nothing !
Bg also sells a diesel moa which is called doa or something along that line. It’s a diesel oil conditioner. Never tried it but I’m willing to give it a try
Back in the 70s they would run a half quart of automatic transmission fluid in the gas tank to clean carbon from pistons and valves. The car would smoke a bit from the tailpipe.
There is a ton of dash cam videos out there of little cars pulling in front of trucks and getting into serious trouble, or even unfortunately, dying. Not the trucker's fault. Probably those politicians that want to stop science education in schools deserve some of the blame. You can't argue with physics –and live. Even if you live, the car will be totaled.
As for the de-carbonization thing, it works if you do it correctly. I have seen several "before and after" videos They put one of those bore cameras down into the cylinder before and after the procedure, and it works, even if the engine is badly crusted up with gunk. It won't get it back to factory condition on a really old and gunked-up engine, but as a preventative maintenance thing, it is definitely worth the money. There is an improvement, no matter what. Not only with the injectors, but also the valves and the combustion chambers generally.
I recently did this on my 2015 buick enclave family truckster, and it smoothed the hot idle out quite a bit. It did smoke like a choo choo train that first test drive though. Pretty sure the Italian tune up it got after that really cleared its throat. I miss port injection.
I have been all over the internet looking for results from induction cleaning. The injection cleaner works but the induction side not so. Get a grip Ray…..snake oil. Unless someone can provide me real proof that induction service works. The best way to help you GDI engine is to install an oil separator (oil catch can).
👍🇺🇸⭐😁
Maytag was a brand at times…yet not as perfect with the guy with a bow tie. A806 was a sweet top load washer… balanced…now who knows what's under the 'bonnet' now … legend has it. We rebuilt them.
I agree, this service is a must for GDI engines. Sea Foam sells a DIY version, actually solved an oil consumption issue in my case.
And who remembers the old water injection systems and put ether or alcohol in the bottle instead of water? Was kind of like an early NOS system back in the day. Yeah I'm that old. You'd be amazed at some of the things we used to do. Especially to those fine Ford flatheads. Hahaha Was fun until the rods let go.
👍
My next direct injected engine that I buy, I’ll be adding a catch can to the PCV hose and adding water injection. Adding a small amount of alcohol to the water reservoir in the winter time will prevent the tank from freezing, and should help to keep the valves clean. Only time will tell for sure though.
and if u use good quality gas.. u wont need to do this procedure
Im sure this helps, but imo the proper fix is just sticking with port injection, the minuscule gain DI gives is just not worth all this crap.
We haven’t seen that wet stuff called rain since May…
so do u believe in a full transmission flush is a good idea in a worn out transmission?
