In this video we pick right up where we left off looking at this Jeep Liberty 3.7L. We determined in part one that the #4 and #6 exhaust valves are not opening. Let's pull the valve cover off and have a look to see if the rocker arms have fallen off. -Enjoy!

Lol, Bob’s your Uncle. Classic
First 25 secs of the video (epic movie announcer voice) – Last time on South Main auto repair !!
I had a misfire on 2 and 4 changed the plugs and coils misfire came back after 2 days of driving good. What next?
Junks
Good day everyone that comments to this problems solved, I'm having problems to same jeep @my place of work,how can get in touch with you sir and it very urgent,we have up to 7 liberty Jeep given the same problems thanks
Run some marvel mystery oil thru it
Ok, so I listen ed to the video again so did it need a new coil? Does it need new rockers as well? I don't know what rockers are😵😩
I didn't hear exactly what was wrong with it.Did say what was wrong with it. I just bought a 2009 Jeep Liberty that was running good last but went to go start for worl and it will not stay running. Just like this Jeep but with less noise. I am a lady and I don't know to do! I had my mechanic put it on the diagnostic machine just like you did but he said nothing with the engine was wrong. Now it wont run just like this one! What did you do to this one to get to run smooth and stay on. Did you clean something?
my 150,000 mile 2008 Liberty runs just fine.
My 04 Jeep Liberty drop the valve seat in the number four cylinder and gave the same symptoms this one was having. My fix was new heads
Hhhhmmm. Do I understand this correctly. But if the intake valve is not opening (stuck). Would that perhaps create a back pressure through the intake circuit. Like, would air puff out of the throttle body?
Really enjoyed watching these 2 parts. Considering when it came in to now . Its almost a new car. I only wished there where more honest mechanics out there like your self. Thats why i love watching and learning from you. Great job.
The worst part is they're likely to pull that piece of cardboard, slap an 'as is – no warranty' price sticker on the window and do NOTHING to mitigate the known problems. Somebody is going to be buying an expensive parts trap.
Me being a tech needs a faster diagnosis LOL. Put the fix in the description
If it were mine I would change those lifter followers and clean all the top end and maybe flush a gallon of diesel through it with the engine hot and run it at idle for about 45 seconds and drain all the schmoo out and let drain for a full day and then change the oil like it needs not what the manual says. Like every year at the very least.
Am I the only one who instinctively held their breath when he blue exhaust in our faces?
Thanks for talking on the phone and skipping the most important parts of getting that fricken cover off. "Just move the wiring harness" my ass.
It looks like it could use a set of lifters
My 09 jeep liberty the rpm only goes up to 2 rpm so do i really need to get the scanner like the one u got to fix my problem
Amazing diagnostics
Bingo. I knew that was it. Commented on part I about having had the same happen to my 4.7 due to overheating for about 30 seconds due to coolant loss from a cracked radiator. I drove mine all day with multiple engine stops with no issues until I got home. Popped the rocker arm back in and all has been good since. If the seats fall out, time for a head rebuild or replacement. When it happened to mine 12+ years ago, there wasn't a single mention on the internet of others having had this happen. I found one mention on a mailing list of someone buying a 4.7L truck for nothing because of "engine failure". Ended up being 2 dropped rocker arms. There are thousands of mentions of others having this issue now if you do a google search.
I've always run fully synthetic so not a bit of built-up anywhere in the engine.
watched twice loved it
Fix cod p2096 and p2098 jeep liberty 2006
Running better now write it up and send it
Exelent very helpful 👏 👌
Well Bobs ur uncle lol😂
Changing oil and filter on time is just so overrated…
"sure you can go fast, but I can go anywhere," follow me to the auction
Worked it out again
They gonna ship that turkey!
This is enough to make me buy a restored vehicle from the 60's.
Really nice diagnosis. You were on the money. Great Job. Learned something new.👍👍
Good job what happen with the vehicle did the owner decide to do the rest of the work?

A great little 2 part series! Thanks Eric.
More great diagnostics and fixes.
Another untested Chrysler design at the customers expense … NEVER buy Chrysler unless you love problems.
Awesome video
Aaand that's what you get when you get the $10 special oil changes!
Hey how's it going?
Had a question about this engine. I'm working on an 05 Liberty 3.7 2WD for my friends mom. I was told it needed head gaskets, when I looked into it, #2 piston got into it with the valves, needless to say that engine was toast. I picked up a long block from a local yard but it was from an 03. Didn't know that the crank and cam timing rings were different. had to go back to the yard and get the right ones, installed then and got everything back together but it still wont run. Compression on 1,3,5 was 120 and 2,4,6 was 90. Also the #1 coil isn't firing. All six are new, but I swapped it anyway with #3 and still no spark. Any suggestions?
Thank you in advance.
You really do stay with the problem until it's solved. Love your videos.
Sea Foam would have saved you a lot of work.
I’ve been pretty lucky with my 4.7 208,000 miles change oil every 3-4000 miles and maintain the cooling system so far so good
Jeep should hire Toyota to design all future drivetrains.
Can this happen on Subaru's HLA engines from the 90s?
Eric the genius diagnostician
Many of the vehicles you work on have the low tire pressure light illuminated on. Do you air up the tires before you give it back to the owner or do you advise them to air up the tires and not to ignore this warning light? Most owners are ignorant of the tire damage being done and if the tires flex too much the tire will blowout. Do you advise them?
Thanks for posting this! Exact same thing happened to the 3.7 Jeep Liberty that I went down to help wrench on today. Luckily I watched your video this morning before heading out and only spent 10 min screwing around before just pulling the valve cover and a rocker arm fell out on to the ground.
