Thank you so much for posting this. I just purchased an '08 that I'm told has a "bearing-like" noise where they tried to R&R the water pump but didn't fix the noise. I suspect it very well could be this issue here. Very cool how you isolated this problem.

My Liberty has 156000 miles on it and started making that same noise too. The jeep has been sitting for about 3 yrs, I do start it up and move it around once a week. I thought it was a rocker that was starting to come off. But lo and behold it wasnt. Ive taken apart most of the front of the engine, so next is to tackel the timing chain. You guys KNOW UR SHIT. Ques would a bad tensioner shoot a timing code as well, every once in a while. I be proud of you boys ty...MOPAR FOREVER...!

I have 2006 Liberty with the 3.7. I have 148,500 mi. And it runs Stronger now than ever with cold air intake and upgraded pipes and converters. Massive improvements in Torque and HP. New GY Wrangler Workhorse AT this will not Stop. Great Engine. An old AMC design..

😂 going through the same thing man gotta redo the timing cover gasket drain coolant again, anyways thanks clay, I'm going to find some 2002 tensioners

Thanks for this video.. I seem to have the same noise and issue. I'm going to do this to my daughters 2007 Dodge nitro

Yo this was so helpful I jus replaced both tensioner and was wondering 1 if it was bad and 2 if I could start it up with the cover off to check

this is problem i have with the jeep liberty 2006 3.7 thank great video keepup the good wor gary mexico

Excellent, fellas! My '07 XK 3.7 makes exactly this same noise at a cold start. Has about 90k on it. Could this be my issue too or does the fact that my noise goes away after about 2 seconds point to something else?

OMG that's bad ass! Thank you!!!!!!!!

Thank you for this information. I just purchased a 2011 and got a full tune-up because I was getting P0304 (1/4) and P0456 (3/4) codes. After a complete turne-up, I drove it, and the next day the check engine came on again, and I started getting this loud knocking noise. Please advise

i have a ? we brought in a 2004 jeep liberty into the shop and 2 4 and 6 cylinders are not firing the customer replace the coil packs on number 2 4 and 6 cylinders and has a cam sensor code also just was wondering if it could be the cam shaft chain or the rockers came off i know they are noted for that didnt do a compress check yet we dont really want to get into all that its a 3.7 engine

Thanks for the video. Great information here. (I’ve never started an engine with the covers off, that was neat!) I Had this same problem as in the video, only for a little while tho... I’m not sure exactly what happened, may have jumped timing and destroyed 2 rockers & lifters and most likely the valves too. Is it junk ya think? I’ve had terrible luck... I have 2 Commanders right now, 1 with these destroyed valves and the other the motor is locked up completely. FML

Well I very much appreciate the kind compliment and I appreciate you watching. Well the motors more than likely locked because the timing jumped and where the piston stopped at generally win the Pistons hit the valves it puts an indentation in the piston itself but generally does not crack it or heard it just depends on how fast it was going when it happened. It’s generally not the end of the world and it’s not just you that has problems with them everybody does they have designed an excellent motor that will only last so long.....

nice video!

The description says "Engine rattle with misfire" what was the Misfire code? P0300 or was it a specific cylinder?

We have a 2012 3.7L with P0175 and it seems like this might be the issue. It had miss fire codes and it the technician changed coil packs and injectors still runs like garbage also both O2 sensors have been changed.

I’m watching the tensioner video and hoping it’s my problem! Just bought a 03 Jeep Liberty 3.7 and it has a knock it’s not loud unless the gas is pushed it gets a little louder but now much. But the Jeep won’t barely go. It has 123k miles I paid $200 for it and it’s clean inside with no other issues. What should I look into first before buying a new engine? The Jeep was owned by one person and taken care of

Well that sounds like a really good deal regretfully without being there I can’t tell you if it’s better off just to replace the motor or try to fix it it’s probably gonna be easier just to replace it and because you bought it right you won’t have much into it anyways

Hey guys thanks for the video liked and subscribed! Quick question for you my 04 liberty 3.7 was dumping coolant into the back passenger cylinder I assumed it was a head gasket and scrapped it. Bought another 04 liberty And have been driving it for six months and now it’s dumping coolant in the same cylinder. When I got this jeep it had the typical popped out rocker issue I replace the rocker and lifter and things have been great until now. Are head gaskets common to go or is there something else that may be an easier fix causing this.

Well yes it is fairly common for these vehicles generally prior to 2005 or 2006 I don’t remember which I don’t see mini head gaskets blown after them years but then they start dropping valves into the engine so that’s not much better

When I start my jeep liberty 2010 3.7 it rattles for 2-3 seconds, what could it be.or what should I try to fix it. Sounds like the top end has no oil. Or the lifter are dry.

@sharpcarco

3 жыл бұрын

Well that noise is generally coming from the timing. That means that something inside there is possibly broken one of the tensioners is not staying extended like it supposed to when you start the vehicle up. So a timing job would be what it requires

Isn't the rachid mechanism on the tensioner suppose to hold it out and not allow it to collapse as per designed ?

@sharpcarco

2 жыл бұрын

Yes that’s what it supposed to do but if you look at them closely they have teeth and the teeth Wear down allowing the tensioner to collapse. This is helped significantly by replacing the tensioners with the tensioner‘s that do not have ports on the tips to allow oil to escape. In a recent video I show you this in-depth and explain to you why the earlier style tensioners that they never even put in this vehicle are better than the newer style ones. 2002 to 2004 tensioners

Trying to catch back up now.Sort of the same issues they had with the 2.4l Hydrolic tensioner .Worked well ,but they changed to a spring tensioner that was kind of junk .I have a 06 3.7l that has that cold tick that goes away when warmed up totally.Can hear seems like the chain.Maybe time to get in there and change out a few things.Runs well with no money light ,but at 217 k who knows what is hiding in there(debating if it aint broke don't fix it,but that idea has burned me before) .Just got it to fix and give it another decade or so of life .Appreciate the time you took with the video.Makes it easier to catch up with this stuff.

hey there thanks for the video keep it up. I also have a jeep liberty but a 2008. right now i am currently working on it and i wanted to ask some questions. So i have a really bad engine knock when i start it up and when i start to speed up, the knock also speeds up. i added the lucas oil additive and it went away but it came back. I want to get it fixed and i want to do it myself i already took the valve covers off and i rotated the crankshaft clockwise and the lifters and rockers look tight and nothing looks damaged i also did a compression test all the cylinders were good. is there anyway you guys could possibly help me out with some advice i would really appreciate it thank you

I have small miss fires in cylinders scan tool says so,so I changed all coils sparks and lead but before all that the head gaskets and chain were changed but still I’m getting bit of a rough idle after warm up and check engine light comes up ???

@sharpcarco

Жыл бұрын

So I’m assuming the check engine light is on for the misfire. Try switching the coil from one spark plug to another spark plug and see if that changes your code. I know you said you replaced them. If that doesn’t do anything make sure you do a compression test because part of doing the head gaskets is doing the head cylinder machine work a lot of times the valve seats drop out of these. And it’s probably losing compression if that’s the case it’s very common that’s why when I rebuild these heads I steak the valve seats from the factory they’re cold set which means they can heat up in fallout

Doesn’t matter if I’m right or if I’m wrong do a Leak down test and you will know for sure you can do a basic compression test first and see if you don’t have a leak down tester but a leak down tester will tell you exactly which valve if any are bad trust me I’ve been to the exact same place you’ve been before so I know what I’m talking about

'The passenger side tensioner is not supposed to have the plate'. Only the drivers side has the plate. Edit: Sounds like you made the mistake by putting one on when you rebuilt it. Neat video though.
