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.

[@jonhobbs8541]

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!

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.

[@Poweraddicts]

[@projectbumblejeep4190]

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.

[@Poweraddicts]

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.

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.

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?

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.

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?

[@Poweraddicts]

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.

[@spymaine89]

by color rocker arms different materials ? why and what.

[@jackiecarpenter7747]

Mine has almost like a top end knock/tick... only on a cold start and goes away after it's warm and with oil pressures.

[@Poweraddicts]

You can pull the valve cover off, start it up cold, when the tick starts push down on each rocker arm. If you push on one and the tick goes away .. you found the cylinder. Change out the parts as demonstrated in the video. If the tick is still there, then it could be a lifter not pumping up or a worn cam lobe. If the tick does NOT go away while pushing on the rocker arms while running the engine, it could be piston slap (which has been known for the 4.0 and 2.5s). Piston slap will require rebuild of the engine including boring the cylinders to the next larger size. If its minor piston slap ... I personally would just drive it and not worry about it. But ... I'm not a picky person and don't stress over subtle things. If it turns out to be piston slap and you wanna rebuild .. go for it ... thats your call. I'm eventually going to do a few engine rebuild videos. Hope this information helps!! Have a great day!

I watched a video from Moses Ludel saying these Jeeps (4.0 inline 6, for one) doesn’t allow for adjustments so a tool is required when doing this. He also named a couple of other times when it would be needed. It is to ensure we get the proper rod length. What is your opinion regarding this tool?

[@Poweraddicts]

I have several manuals relating to the 4.0 and 2.5 Jeep engines. They all say to torque the rocker arms to a specific setting (not once a special tool was mentioned). I even looked in the legit service manual that Chrysler themselves use to service these engines ..... no tool was mentioned. What we demonstrated in the video is correct to Chrysler standards on a non-modified engine. That Jeep in the video still runs perfectly after the actions performed in this video. I found that video you mentioned. In that situation he mentions after a valve seat grind ... yes .. after a valve seat grind the tool is needed. I have one and I have used it on modified engines. An engine in stock configuration like the Jeep in this video, no tool needed.

[@manualtuning5222]

I have a rattle in my 4.0 when I first start it up but once the engine warms up the sounds goes away, 160k miles, could it be rocker arms or lifters?

[@Poweraddicts]

The ones I've seen were like that.

[@williamstewart8881]

How do you know the rattle is not from the lifters?

[@Poweraddicts]

Experience from working on these engines. About 90% of the time its the parts we changed in this video. There are times that it has been the lifters but it isn't common. That engine hasn't rattles a bit since we changed those parts.

[@williamstewart8881]

Thanks. Mine sounds like a diesel. I’ve got the parts, and thanks to your video I got this!

[@cantfixstupid5503]

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"??

[@Poweraddicts]

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.

[@michaelshifflett5659]

Will motor do side to side shake if the rockers are worn like it’s out of time I replaced lifters, pushrods, seals but not the rockers and they all went in same way the came out, didn’t mix them up

[@Poweraddicts]

Typically rockers will not cause any side to side shake. You may wanna check your engine mounts to see if the rubber is worn out.

[@RandallOre]

So I take it that it’s not crucial to change out the lifters? Am I correct? Because I have a 2.5 doing the same thing.

[@Poweraddicts]

If the tick is coming from loose and worn out rockers then there is no need in replacing the lifters. Typically if you had bad lifters you would have more issues than just rattling a noise.

[@Conroyc13]

Sorry another question ....if I removed the push rods and rocker arms can I put them right back on or do i need to make sure it is at TDC before torqued?

[@Poweraddicts]

Dont worry about top dead center. Just put them back on and torque to spec.

[@GagandeepSingh-br7ej]

Hi, can you please fix this noise of my jeep 2.5?

[@Poweraddicts]

Try changing the rockers, pivots, and push rods like in the video. If it is a rocker tick this should help.

[@NCmountainsYouTubeChannel]

I’d like here it run before and afterwards,,

[@RcbasherNcrasher13]

I have a 98 cherokee 4.0 I bought all new rocker arms guides and pushrods.. will this work for my jeep top end rattle especially on cold starts.???. thx

[@Poweraddicts]

If it is the rockers making the noise. The TJ in that video did it mostly upon cold starts. So, if yours is because of worn valve train parts, the new parts should fix it. Rare that it is, on cold starts I've seen engines have light piston slap until they warm up. That can only be fixed with a rebuild. I really see the need for me to make a video diagnosing rocker/lifter tap. Keep an eye out for that video soon.

[@RcbasherNcrasher13]

Yeah it does have a tic warmed up but not as bad a new hemi tick..lol.. it's gonna have a all new top end after this.. head came off for freeze plugs so it got new guides.. but bottom end hasn't been touched that I know of. But when valve cover first came off it was clean inside no sludge no deposits

[@brianadavis685]

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?

[@TheTequilero98]

Can you adjust the valves on a 2000 jeep wrangler?

[@Poweraddicts]

That is a 2000 model Jeep Wrangler in this video. In the video it was said that the valves are not adjustable.

[@vinces.2862]

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.

[@Poweraddicts]

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!

[@nomorebsforme]

ANy special info on the Dodge ram 2500 3.9 doin the rocker arms and lifters?

[@Poweraddicts]

Never worked one one. Sorry

[@Maxxis1941]

Would gummed up push rods and/or worn followers/value covers create a knock but only when I've reached full operating temp oil pressure? I'm also getting a minor exhaust sputter when the knock starts. To add to the mystery, the knock and sputter goes away if I shut it down for 3-5 minutes.

[@warchildwarhammer8837]

Did you ever get any info?

[@Maxxis1941]

@@warchildwarhammer8837 There's no reply to read, is there? No, I didn't.

What’s your favorite oil for the Jeep 4.0?

[@danr.9522]

I just started using Royal purple in my 2002 Grand Cherokee 4.0 L...... It's a little more but it runs awesome at 257,000 miles and at a cooler temperature. Also a Mopar oil filter with check valve.

[@Mike__S]

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?

[@Poweraddicts]

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.

[@dandahermitseals5582]

Me too. I figured bad lifter. Can u change lifters in this engine without pulling head?

[@v12alpine]

@@dandahermitseals5582 unfortunately you have to remove the head. The holes are too small to fit the lifters throuhg.

[@davidnicoll9140]

Bro, great video, you need to update your amazon affiliate links

[@Poweraddicts]

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!
