@@MeatPez - I’ve been a professional Auto Tech since the early nineties but I get your point.

Absolutely wonderful instructional video for solving a problem that 99% of all TJ owners have; even down to torque lbs and gasket model. You hit on every necessary detail and made this engine repair within reach for us novices! Thanks for posting!!
I recently purchased a 2000 Jeep Wrangler 4.0 and was dealt the cracked and dreadful cylinder head. This video had every step and every detail to complete the job. Thank you Cruz
Great job! You've convinced me to do this to my '98 XJ. Very good camera work and straight to the point. Definitely one of the most helpful vids I've seen in quite a while. Keep up the good work!
Great video! Love that you even show people the basics like the appropriate way to use a torque wrench. Even to take tension off before storing it. Been using torque wrenches for 40 years and never really thought about the appropriate way to use them, even though I do everything you said. Not everyone has the wisdom that you share.
You guys are legit for sure. Easy to understand very informative and you’re talking about the important specs and highlights of the task. Not a bunch of extra BS. Plus I can tell that you know from experience and time on the job not just saying shot to say it. Thanks , you are mechanic animals. Edit: I’m in Columbia just 35 miles south of y’all. No wonder I could understand you easy .. lol
Thank you for an excellent video. I learned a lot. You do an excellent job "de-mystifying projects in the Jeep! Saving me $$ on getting my old jeep fixed on a budget.
Figured I’d use your site to find good quality rockers, brackets, push rods and gasket. Everything else I found were cheap trash. Thanks for good products!👍🏻
Thanks for the ending comment about the restoration of power, I have exactly that problem, I replaced the injectors, which helped but I also have a misfire code on cyl 3. The ticking is pretty bad. I'll check out the rocker arms. I have over 200k miles on the rebuilt head.
I built sooo many model cars as a kid. I grew up and so did my models 😀. I enjoy working on them and most of all building them up. Glad you are enjoying your new hobby! Hope the vids help you!
Great video!!! My XJ has 280000+ miles on it and I'm going to put stock ratio roller rockers in it. It still runs like a champ. I have the same valve cover gasket on mine. So far, the only major thing I've had to do on it, is change the cylinder head gasket in addition to the other gaskets.
Great video! Thanks to you, I pulled off the job no problem. After a BG109 engine flush and new plugs, Still had some unidentified ticking- thinking maybe lifters but then discovered slight exhaust leak on one of the flanges at the pre cat. Just thought maybe, for those interested, try tightening those bolts up first (booger to get to, but a wobble 15mm socket with extension did the trick) The forward flange bolts were a little loose and it worked like a charm. It just might solve that ticking noise before diving into the bigger project?? Regardless, really appreciate your awesome instructions as my engine has never sounded better!
Seems like a lot of these parts fit TON of years 4.0. I just got a 95 YJ, still catching up on it's maintenance. Prior your release of this video I just did the valve cover gasket. You know, I thought it was noisy in the rocker area. Man, wish I knew all this before. I also need to fixed my CAD, need to install new engine mounts, new exhaust header too. Previous owner kid did some poor work on this jeep. I'm going to check out your website.amd other videos. Thanks for your channel!
Thanks Bruhda. I just slapped a reman in my 02 tj. It didn't pull like I thought it should. I'm a small block chevy shade tree mechanic. I was about to set TDC on every piston. Lol. Thanks for all your time an wisdom on the 4.0. Thank you
I get that question a lot about having to set TDC for each cylinder. Ford and Chrysler/AMC, you don't have to worry about that. I've build a many small block and big block Chevy's so I totally understand what you are saying. You are welcome! Glad the video helped you!
Felpro oil pan and valve cover gaskets ALWAYS!! 👍 I've bought engine kits that come with some other brand valve cover and oil pan gasket. I'll go buy the Felpro Permatorque separately every time. Gaskets such as water pump and thermostat gaskets I'm not as picky.
I've got an engine on the stand that's gonna get rebuilt. I can simulate swapping lifters on it. All the rigs I have access to right now are running great. If you're referring to top end valve rattle, most of the time it's the rocker arms and rocker arm pivots are worn out. The fella that owns the TJ that I did the rocker arm video on keeps talking about putting a high performance cam in his. If he does I know I'll get the video on that as well.
Love these AMC 6s and V8s; non adjustable lifters; so easy to work on; thanks; great video !!!!!!!!! Greatly maintained engine too; and Melling is an excellent quality part !!
I have a 2000 XJ Sport with the 4.0 6 cyl. I'm getting the rattle and a misfire on #5. I'm guessing and hoping this will do it. I got the jeep with 315k KMS (195k MILES) for $500 CDN ($395 USD) with no tires(owner bought it for the tires and sold it to me as a slider) in 2018. I sent it to Bakers 4X4 here in Ontario Canada and restored it with some body work/floor pans/rockers and I'm just crossing 320k KMS (198k MILES). The bonus is it came with a 6 inch RC lift. Thank you for the video and the PRO tips. Fly fast shoot straight and never look back!
My rockers are all tight on my 2.5, just rebuilt last night. It was a lot worse than it was now, I had them too tight, redoing them to the correct torque quieted it down but it still ticks
Man you should get paid for this vid! Coincidence -- mine is very close to same as yours. Also 2000 TJ with 177k miles. Bought it new in 2000 and have taken good care of it. And alllll this time I've been putting up with that clicking, that's it? lol. I've been putting it off and dreading it, assuming I was gonna have to adjust everyone of those freaking valves! Your video probably just cut my time in half and saved me a lot of guess work. Now I already know what to buy so I can just buy everything first and have it ready. You made it look easy. Just hope mine goes that well. Thx a bunch!! By the looks of all these comments, it must be very common after around 20yrs/175K miles. But on a scarey note...... On my job, I picked up an engine that had blown at 220K miles, that was also a 2000 4.0. Again, he bought his new and took care of it. He said it just simply wore out. #6 piston skirt just wore thru at the pin. So that may tell me what to expect in the future.
Glad the video helped you!! That is kinda rare for for the piston skirt issue. I have been building engines for MANY years .. thats rare for a normal wear that has been taken care of.
Had a lifter tick ,pulled the cover and watched the no.2 cyl exhaust bleed off fast so i loosened the rocker arm off then re tightened, no more tick I think the check ball was not seating, 100 miles and still no noise
Fantastic video!!!! I definitely have this going on in my 89 YJ. It's got a '92 4.0 swapped in w/ about 90k miles, and for the first 82k of them, I'm unsure what maintenance was like before I got it. Huge thanks!
Ive watch this video 3 times by now, i have a similar issue, my rockers are loose i can wiggle them myself no matter how much i torque the bolts no change
Best instructional video I've seen on youtube, & all the tips are great. It feels like I'm listening to a real experienced mechanic. Now if you can tell me how to get the brake banjo bolts from leaking fluid then I will be happy. I tried stat-o-seal washers and it still leaks. I noticed that the rebuilt calipers from Autozone have the banjo bolt washer mating surface sandblasted and I believe thats whats causing the leak. I think I will need to sandpaper that mating surface to reduce the roughness on it so it will seal correctly. Don't see anybody else giving tips on how to do such a procedure?
Awesome.. I'm swapping my head bc it's cracked. 0331 head. My concern was the rockers.. some say you have to cycle the motor and tighten each one at TDC, but you just torqued them as the set.
Some engines have a specific valve lash setting that can only be set by doing certain rockers at certain piston positions. Older GM engines you have to cycle the engine. Most older Ford and Chrysler engines you can just torque them down and roll.
Great video. I'm getting ready to do this install on my TJ. I was curious though if used any lube or grease on the rocker arms during the install outside of what we saw in the video. I've watched several other installs where this method was used.
Thanks! I don't think we did. But, we should have to prevent galling. As long as its a quick start up getting the oil to the top of the engine there shouldn't be an issue. Good luck, thanks for checking out the vid!!
Pull the motor out of my 79 J10 EMC to 58 Six, rebuilt with a new parts Including top end kit. However now it sounds like a diesel. Thinking it could be the oil pump not circulating the oil properly. Any ideas? Appreciate your time and efforts.
The only problem with tightening up the top (valves, rockers, push rods, lifters) is that the next weakest link is the rod bearings. Had a valve job done on a high mileage motor (300k+) wasn't more than 5k later and the rod bearing went. Lost power and started knocking and blowing smoke. Guy who did the valve job told me I should have done the bottom t the same time. I rolled the dice on it and lost. Great vid! God bless and stay well.
Bud, I dont know who told you that but they are wrong. I have been building engines since I was 15 years old. I'm 50 now. Tightening the rockers has NOTHING to do with the condition of the rod or main bearings. That engine had bigger issues to begin with if that happened.
What would cause A dead miss on A 1990 wrangler 4.2? We put new plugs and wires, adjusted the carburetor, it has new rotor and distributor cap. The compression is 2 psi above or below 125 on all 6 cylinders. It has loud pecking sound under the valve cover on what sounds like #3 cylinder. I wouldn't think the rocker wear would be enough to cause A dead miss, I could be wrong though.
Question: All 24 of the lifters, 10 valve covers and a camshaft have been replaced on my 2014 Jeep Grand Cherokee. Now it is reading codes for a IAT sensor that I will order today and for camshaft sensors. Research online says that a reprogramming is necessary for the camshaft sensors. Someone else told me the check engine light will go off after driving it so long. What do I need to do?
That would be the easiest way to start. Probably 95% of the time this fixes it. If it is still there after changing these parts, it is time for a new cam and lifters.
@@Poweraddicts Thanks for the link to the push rods. I also want to do my valve stem seals. I can live with a little puff of smoke when it starts up, but it seems good to do while I have stuff apart. Since I have to remove the springs to do that anyway, would you recommend replacing them? Not anxious to spend the extra $$ on springs, but also don't want to short-change myself. The Jeep has 185,000 miles on it.
my engine is a 3.8 I want to know if this would be the same routine to switch the lifters on that engine since I can find videos that are specifically geared to 3.8 liter engines
Just completed a full 1996 Grand Cherokee 4.0 rebuild at 191K miles. Much valve train wear due to using Castrol Syntec oil with no ZDDP anti-wear additive. Everything you changed we changed, but our machinist said the cam, lifters, and timing chain also were badly worn. The bottom edge of the lifters were worn down razor sharp where the new lifter had smooth round-over. Did you use a bore scope to inspect the cam lobes for wear?
Nope, didn't look down in the lifters. There was some wear on the top end parts we took out but it wasn't anything alarming. You on the other hand have much more parts wear it seems. It may be time for a new cam and lifter kit for you.
@@Poweraddicts New cam, lifters, push rods, timing chain/gears, and oil pump are installed. New pistons, crank journals ground, new main bearings too. BTW - piston slap is what caused the noise in our 4.0L, especially #3 where the piston skirt on one side was close to cracking completely off.
Hi there. Went to check the amazon links you have for the rockers and push rods and both gone. Did you use a specific brand of rockers and rods? Terrific video. Thanks v.
I had to remove the links. Amazon changed some stuff around apparently making all the links invalid. The fella that owns the TJ just went to Autozone to get all the parts. Hope that helps!
Excellent instructions thank you. But after getting everything back together, no leaks and sounded great I started driving and would idle at 2000 rpms unless I shifted down and engine is running super hot (gauges are fine) throwing p2096 code. I’m trying to figure out how doing this has created this problem? Any thoughts?
I have a stuck or burnt valve… I tried pulling the valve cover to run it to visually inspect and the engine runs away revving. Is that indicative of a stuck intake or exhaust valve?
Could running it low of oil for a few seconds make top end rattle worse, mine knocks worse after it ran low of oil (my fault I used the wrong filter and I feel like a idiot now) not sure if its a new knock or it just made the top end rattle I already had worse. Fingers crossed it's till my top end
Thank you for the video.... I just bought a 95 yj with 200k miles thats been maintained very well (receipts for everything and a milage history that notes miles towed -60k of those miles were towed) dating back to 78k miles). Can anyone point me to a video that might demonstrate the rattle? Not sure if i have this issue, and you I'm unsure if you're playing mind tricks on me and just the suggestion of this issue is making me THINK i hear it. Thanks and keep the videos coming!
We never did get the before and after sounds. It is a slight rattle that seems to come from the top of the engine. If I ever run across another engine making the sound I'll sure video it.
Amazon has drifted more towards the newer V6 Jeep engines. I can only find one set of 4.0 rockers but they have too many bad reviews. I do check every so often, thanks for looking out! And thanks for checking out the video. You can find the parts at most of your basic auto parts store as well. Have a great day!
When doing the rocker arm/push rod replacement like you did in this video, did you also change out the lifters? I am personally experiencing the rattling and it gets quiet after the motor gets up to operating temperature. How far do you recomend going in on a job like that?
Nope, didn't do the lifters. He and I have talked about putting a hotter cam in it. Its his rig so I have no idea if that will ever happen. I personally would do just what we did in the video. Change pushrods, rockers, and the pivots. Changing cam and lifters is fairly involved job.
You NEVER loosen your torque wrench to the point you hear rattling inside the handle. NEVER. Reduce your wrench to the lowest torque setting on the handle markings. Been using micrometer style torque wrenches for 40 years and you absolutely will throw the calibration out of whack by turning the adjuster all the way out. Minimum torque setting on the scale is always recommended.
hey there! you mentioned "you dont have to worry about cam/valve timing.. just take em off and put em back on.." Do you have to do any TDC or closed valve position? Or are they all just "remove and reinstall with torque spec"??
Remove and install making sure they are torqued properly. Really easy. Most Chrysler and Ford engines do not require doing TDC or valve position. GM engines do.
If the push rods are not blocked or bent. And the end balls not galled worn or loose can they be reused with the new rocker arm kit. I got 3 Jeeps running 15w40 oil, the Grand Cherokee from Alaska with 208,000 miles & oil changed regularly with synthetic from previous owner ticks badly on start ups till it warms up gets much quieter but still there. Thanks
We just used brake cleaner to clean the lifters. Installing new lifters isn't as easy as installing the rockers and the other top end parts. Thanks for dropping by!
I just rebuilt my 04 4.0 and put these exact rocker arms on and torqued to 19ftlb I rotate the engine a few times and re torqued but on a few I have play and it’s ticking. Should I take them back off a redo it or just try tightening them up more until they stop?
The only thing about the video that you forgot to do was start the engine up at the end and let us hear it versus how it sounded at the beginning
I was thinking the same thing. What’s it sound like now…..
Hell, he forgot to start it at the beginning to let us hear what it sounded like originally. 🤦♂️

The only problem with tightening up the top (valves, rockers, push rods, lifters) is that the next weakest link is the rod bearings. Had a valve job done on a high mileage motor (300k+) wasn't more than 5k later and the rod bearing went. Lost power and started knocking and blowing smoke. Guy who did the valve job told me I should have done the bottom t the same time. I rolled the dice on it and lost. Great vid! God bless and stay well.
Bud, I dont know who told you that but they are wrong. I have been building engines since I was 15 years old. I'm 50 now. Tightening the rockers has NOTHING to do with the condition of the rod or main bearings. That engine had bigger issues to begin with if that happened.
@@Poweraddicts Made them the weakest link, I should have had him do the rods, mains and rings at the same time. Might still be driving that motor.
What would cause A dead miss on A 1990 wrangler 4.2? We put new plugs and wires, adjusted the carburetor, it has new rotor and distributor cap. The compression is 2 psi above or below 125 on all 6 cylinders. It has loud pecking sound under the valve cover on what sounds like #3 cylinder. I wouldn't think the rocker wear would be enough to cause A dead miss, I could be wrong though.
Question:
All 24 of the lifters, 10 valve covers and a camshaft have been replaced on my 2014 Jeep Grand Cherokee. Now it is reading codes for a IAT sensor that I will order today and for camshaft sensors. Research online says that a reprogramming is necessary for the camshaft sensors. Someone else told me the check engine light will go off after driving it so long. What do I need to do?
Hey Chuck, does this order of work apply also to the 2.5 Renix 1990 motor?
I have a 2.5 and I have tick that’s from the top end will solve my problem? Great info by the way. I’m going to take mine apart this weekend
That would be the easiest way to start. Probably 95% of the time this fixes it. If it is still there after changing these parts, it is time for a new cam and lifters.
Thanks for another fine video. Does the rocker arm kit linked in Amazon include the pushrods? I don't see them listed.
Nope, apparently I forgot to add the link for those. Ooops. I'll add it when I get the chance. You're welcome! Glad you liked the video!!
@@Poweraddicts Thanks for the link to the push rods. I also want to do my valve stem seals. I can live with a little puff of smoke when it starts up, but it seems good to do while I have stuff apart. Since I have to remove the springs to do that anyway, would you recommend replacing them? Not anxious to spend the extra $$ on springs, but also don't want to short-change myself. The Jeep has 185,000 miles on it.
my engine is a 3.8 I want to know if this would be the same routine to switch the lifters on that engine since I can find videos that are specifically geared to 3.8 liter engines
Just completed a full 1996 Grand Cherokee 4.0 rebuild at 191K miles. Much valve train wear due to using Castrol Syntec oil with no ZDDP anti-wear additive. Everything you changed we changed, but our machinist said the cam, lifters, and timing chain also were badly worn. The bottom edge of the lifters were worn down razor sharp where the new lifter had smooth round-over.
Did you use a bore scope to inspect the cam lobes for wear?
Nope, didn't look down in the lifters. There was some wear on the top end parts we took out but it wasn't anything alarming. You on the other hand have much more parts wear it seems. It may be time for a new cam and lifter kit for you.
@@Poweraddicts New cam, lifters, push rods, timing chain/gears, and oil pump are installed. New pistons, crank journals ground, new main bearings too. BTW - piston slap is what caused the noise in our 4.0L, especially #3 where the piston skirt on one side was close to cracking completely off.
I have a 88 yj that has a idle issue , when you push the accelerator all the way down it wants to hesitate.
Hi there.
Went to check the amazon links you have for the rockers and push rods and both gone.
Did you use a specific brand of rockers and rods?
Terrific video. Thanks v.
I had to remove the links. Amazon changed some stuff around apparently making all the links invalid. The fella that owns the TJ just went to Autozone to get all the parts. Hope that helps!
Good video Thanks !! just asking what was the noise the jeep making before you fixed it for referents
because I have a jeep making a noise up there!! but the oil was really old and black and thick
Can I use this info and gasket on my 96 jeep grand Cherokee 4.0?
You got links to the 2.5 stuff or can I use the 4.0 stuff and just have extras for when it does it in another 200k miles lol
Is it common for the new rocker arms to have a little play side to side after you torque them all down to 19ft pounds.
Excellent instructions thank you. But after getting everything back together, no leaks and sounded great I started driving and would idle at 2000 rpms unless I shifted down and engine is running super hot (gauges are fine) throwing p2096 code. I’m trying to figure out how doing this has created this problem? Any thoughts?
Check the pcv valve, crank breather, and vacuum lines, sounds like it's sucking in air from somewhere.
I agree with @Gabriel Herrera. Sound like you have a vacuum leak somewhere.
Those holes do no align with the push rods. No complications with that?
I have a stuck or burnt valve… I tried pulling the valve cover to run it to visually inspect and the engine runs away revving. Is that indicative of a stuck intake or exhaust valve?
Could running it low of oil for a few seconds make top end rattle worse, mine knocks worse after it ran low of oil (my fault I used the wrong filter and I feel like a idiot now) not sure if its a new knock or it just made the top end rattle I already had worse. Fingers crossed it's till my top end
Thank you for the video.... I just bought a 95 yj with 200k miles thats been maintained very well (receipts for everything and a milage history that notes miles towed -60k of those miles were towed) dating back to 78k miles). Can anyone point me to a video that might demonstrate the rattle? Not sure if i have this issue, and you I'm unsure if you're playing mind tricks on me and just the suggestion of this issue is making me THINK i hear it.
Thanks and keep the videos coming!
We never did get the before and after sounds. It is a slight rattle that seems to come from the top of the engine. If I ever run across another engine making the sound I'll sure video it.
The Amazon rocker arm link didn't work can you tell me the brand rockers you used
So I fouled up and broke one of the bolts where can I get a replacement one? dealership said they are discontinued
can you update the links for the parts?
I’d like here it run before and afterwards,,
Bro, great video, you need to update your amazon affiliate
links
Amazon has drifted more towards the newer V6 Jeep engines. I can only find one set of 4.0 rockers but they have too many bad reviews. I do check every so often, thanks for looking out! And thanks for checking out the video. You can find the parts at most of your basic auto parts store as well. Have a great day!
I’ve had 2 4.2S and they both had this problem lol
It is a very common things with the 2.5s, 4.0s and 4.2s. They just rattle along for MANY miles.
When doing the rocker arm/push rod replacement like you did in this video, did you also change out the lifters? I am personally experiencing the rattling and it gets quiet after the motor gets up to operating temperature. How far do you recomend going in on a job like that?
Nope, didn't do the lifters. He and I have talked about putting a hotter cam in it. Its his rig so I have no idea if that will ever happen. I personally would do just what we did in the video. Change pushrods, rockers, and the pivots. Changing cam and lifters is fairly involved job.
Me too. I figured bad lifter. Can u change lifters in this engine without pulling head?
@@dandahermitseals5582 unfortunately you have to remove the head. The holes are too small to fit the lifters throuhg.
Where would you recommend getting these kits now because the Amazon links don't work anymore and I can't seem to find either on amazon
Any autoparts store can get you the parts
Why not use roller rockers? Also, great video. Thank you for this.
To me roller rockers are a waste of money on these engines. Thanks, glad you enjoyed the video!
Would this rockerarm kit work on 92 4.0 yj?
You NEVER loosen your torque wrench to the point you hear rattling inside the handle. NEVER. Reduce your wrench to the lowest torque setting on the handle markings. Been using micrometer style torque wrenches for 40 years and you absolutely will throw the calibration out of whack by turning the adjuster all the way out. Minimum torque setting on the scale is always recommended.
hey there! you mentioned "you dont have to worry about cam/valve timing.. just take em off and put em back on.." Do you have to do any TDC or closed valve position? Or are they all just "remove and reinstall with torque spec"??
Remove and install making sure they are torqued properly. Really easy. Most Chrysler and Ford engines do not require doing TDC or valve position. GM engines do.
If the push rods are not blocked or bent. And the end balls not galled worn or loose can they be reused with the new rocker arm kit. I got 3 Jeeps running 15w40 oil, the Grand Cherokee from Alaska with 208,000 miles & oil changed regularly with synthetic from previous owner ticks badly on start ups till it warms up gets much quieter but still there. Thanks
I have reused them and not have any issues. Just make sure they are in good shape.
Watched this while at work. This will make your health insurance premium go up. Sorry.
Thangs happen 😀
by color rocker arms different materials ? why and what.
Do I need to clean the rockers and rods prior to install? If so what do I use? I'm debating dropping in new lifters also. What's your thoughts?
We just used brake cleaner to clean the lifters. Installing new lifters isn't as easy as installing the rockers and the other top end parts. Thanks for dropping by!
ANy special info on the Dodge ram 2500 3.9 doin the rocker arms and lifters?
Never worked one one. Sorry
I just rebuilt my 04 4.0 and put these exact rocker arms on and torqued to 19ftlb I rotate the engine a few times and re torqued but on a few I have play and it’s ticking. Should I take them back off a redo it or just try tightening them up more until they stop?
After changing all that and its still ticking, you may have worn lifters. Go ahead and recheck the torque on the bolts first.
