[@Solidus2845]

Sometimes I find your videos to match my current project. Other times, I just watch them like a series! I have to say...if I did all that work disassembling my engine (Dealing with the entire engine full of coolant is just the most annoying thing to me), I would absolutely just replace every single part I could access before putting it back together. Even if it looked just fine, I'd replace it all with brand new after that! I love watching how this Jeep came to be. Edit After watching whole thing: Hysterical how you were talking to the stubborn lifter on 6, rofl! These damn Jeeps are so rewarding to get right when you get them dialed in and maintained, but so infuriating when you spend days on a painful, time consuming, sometimes expensive repair which has absolutely zero effect on your problem. I swear at least half of my repairs end up with me going "Well...I guess those parts are new, now..." having no effect whatsoever on the rest of the engine's function.

[@cablenowadays6586]

I got 200k and about a day later i didn’t play my music loud when i was driving and i could hear a little tick. I knew it was my lifters and just wanted to watch a video to see how i do it on a 4.0. Took me and dad about 5 hours and a lunch break to replace all 12 and i got to paint my valve cover and put a new gaskets in to get rid of my oil leaks. makes me pretty happy

[@randyparker3678]

honestly thank you this video just sealed the deal. I'm now confident I can do this job right 😊

[@TheodoreStanke]

make sure when you put new lifters to grease the camshaft contact surface with moly lube or you risk destroying the camshaft. Then you're supposed to run it 20 minutes at 2000 rpm to break the lifters in. been there with my '89, it worked! Good luck

[@NickInTimeFilms]

This is how I broke in my engine. Let it start and idle for 30sec till everything sounded decent, then 20min break-in. Cam and lifters turned out fine, had a piston slap issue after 600 miles, but that's a different set of parts.

[@mpetersen6]

Believe me. These engines when assembled at the factory were never run at 2000 rpm for 20 minutes. Infact these engines where never even run under power until they were started to drive the vehicle off the end of the assembly line. The only time these engines were turned over in the factory was any hand rotation for assembly purposes and when they were spun on the cold test stands for maybe a minute tops. This was done to check a number of engine conditions. Spark timing, compression, oil pressure, oil pressure relating to crank to oil supply inlet and numerous other functions.

[@LaserLuther]

A lot of times you can pull a plug and the slap will go away with the loss of cylinder pressure, it will be a little loud with the air coming out of the plug hole but the noise should go away. you can also snake a piece of 1 1/2 inch pipe up against the block to listen, some guys will put a plunger or funnel on the ear side. I would say these tricks work 50%. It sounds like a cracked piston skirt or loose wrist pin to me. I have heard loose fly wheel and flexplate bolts sound like this. I would also check the balancer and look for extremely fine cracks in the rockers.

[@seanossel7114]

I put an exhaust headerish manifold on mine because of the crack they always get and it looks almost exactly like yours. I found that the new manifold had a thicker flange than the old one and because the bolts hold on the intake too, I was getting a bad vacuum leak along the top of the intake. I could spray some brakleen on it and it would rev up; kinda funny. I had it measured and the difference between the intake and exhaust was 70 thousandths. I needed to shim the washers on the bolts to hold it evenly so I cut some slots in some some nickels so the would fit around half the bolt. Nickels are 68 thousandths so it worked great. I thought you mentioned something about that in one of your videos so if you haven't done something sufficient to fix that you may want to look at that. That may be part of your exhaust leak too.

[@mpetersen6]

One way to make sure your parts stay organized is get a bunch of plastic bags. U-Line is a good source. Label the bags and put the clean parts into the bags immediately. I'm not sure if the pistons were moly coated on the skirts in 89 or not. I think that came in about 98. And in case you do not know the piston skirts are not round. They were intentionally made Oval. The skirts should be about .012" of an inch smaller here than across the skirt perpendicular to the wrist pin. The only part of the piston that should actually touch the cylinder walls is this area. Now somebody needs to figure out a good way to put roller lifters in. Those casting ribs are in the way.

Man i know the feeling. I had been chasing down an exhaust leak on my xj and after taking off the manifolds reworking the whole exhausts, welding in new flanges and putting it back together, the things still leaked. Having already swapped a head on my xj, I feel your pain when you started it and heard you had not fixed it. It sounds to me more like rod knock or piston slap unfortunately. See lifter tick is just that, a tick kind of like a watch. What your engine is doing sounds more like a sloppy wrist pin or piston. I am sure you will find out what it is but it sounds like an expensive repair. Good luck

[@NickInTimeFilms]

+charles villeneuve You're spot on, next week we'll actually get around to fixing it. I jumped to lifters because I wasn't properly diagnosing it. The beginning of the video shows what a lifter tick actually sounds like, and I figured since I have the footage I might be able to help someone else do the job if need. Just wish I knew then what I do now. haha.

[@charlesvilleneuve4052]

+NickInTimeFilms from your comment, I gather that you have already found the issue. If that's the case good for you. Also if that lifter was bleeding out, it was probably on its way out anyway.

[@NickInTimeFilms]

+charles villeneuve More editing magic, that was one of the new lifters without oil before I started it. I'm thinking an overheat issue and thick straight weight oil on a cold morning warped the wrist pin and it started wearing out the piston ring until the piston skirt started contacting the bore.

+NickInTimeFilms perhaps on a freshly build engine it made a difference but mine ran all summer on 15w40 rotella even on some cold Canadian mornings(in Summer, mind you ) with no audible damage. It did knock a bit when cold but the noise went away once it warmed up. I switched back to 5w30 for the winter and it stills runs like a champ.

Bummer dude, but you sure got diagnostics and repair ability on your side. I replaced a timing chain about 30 years ago, on my 79 Dodge Magnum. What a nightmare of a chore. I got through it, and it lasted until I donated, at 191,000 miles . I got the car with with 54K on the clock. I should have gotten a Jeep back then. It had around 86K on the clock when I did the timing job. Worst part? It didn't need the timing chain job, AT THAT TIME. I sure as hell didn't need the aggravation the job gave me. But, I drove it, and it still ran strong up to the donation point. So, I kind of know where you're at. I bet it is piston slap like you suggest, but I hope you get another 4 wheeler to replace it. Have yet to check out the other video you indicated.

Once you replaced rocker bridge assembly and torqued them down, did they still move around..depending on where the cam was positioned?

Did you finally get it solved ? If you did what was your solution? - I also read that if you replace the lifters, you should replace all of them and the cam shaft. " Tolerance issues....must be, I would think that the springs on the valve stems + lash gap + pressures within the lifters would make up for the Tolerance differences" - When I read this in a manual, I was getting skeptical about the BIG motor companies that want us to just buy parts. So DID YOU SOLVE IT YET ?

[@NickInTimeFilms]

As long as the collapsed lifters did not wear away the camshaft lobe, it's fine to reuse the camshaft. It's only good practice to replace all lifters in an older engine since the others are sure to go eventually. I believe you are suppose to do a camshaft break-in procedure however to harden the lifter bottoms. This was a fresh rebuild so I wasn't worried. As for my issue, it was actually piston slap. video of course:kzbin.info/www/bejne/jHLOnp-sjJ6Zj6M

Brody, you are a ABSOLUTE carguy. Your vernacular matches errrrry car guy i know. and fuuuuuck me, time to figure out if my guys jeep is a lifter or piston slap. FML

[@LRamirez3rd]

Since the lifter tick wasn't your issue what was it?

[@NickInTimeFilms]

Piston slap. Next video went over that.

[@pawpatina]

12:42 me, every day... LOL

[@robertmorin6495]

Your video is about 24 minutes long. At the 5 minute 37 seconds mark, you pull a lifter with a magnet. The flat shiny side is facing up. At the 5 minute 56 seconds mark, you pull another lifter out with a magnet. The flat shiny side was not facing up! This can be seen by pausing your video with the space bar key as they are being removed. Was the second one actually installed wrong or did you quickly put it back in the hole because you forgot to start the camera or something?

[@mitchellwatson9344]

can the lifters stick and make the engine back fire?

[@NickInTimeFilms]

I feel like that is more of a timing issues then lifters.

[@ninjaraku]

13:00 sounds exactly like me with my zj lmao

[@dre04mach]

that last bolt would be easier with a piece of fuel line/hose wrapped around it. how did removing the head/intake/exhaust as one piece work out compared to the normal way? i removed the head the old fashion way and getting those exhaust bolts on was a bitch!

[@SUPERSTUD6000]

how many times have you torn down your engine so far? maybe that tightness in the the last lifter port when you reassembled is what caused it to wear and start tapping.

[@NickInTimeFilms]

+barry soetoro Maybe I should start a tally. I'd say 3-5 times so far. I'm getting pretty good at it. haha

[@SUPERSTUD6000]

NickInTimeFilms you might be hearing the valves through the exhaust leak on the manifold. the 4.0 tended to have shit factory exhaust manifolds that would commonly warp and crack.

[@NickInTimeFilms]

+barry soetoro it has a cheap aftermarket header that is warped. This issue here is piston slap, it'll be covered next week.

[@victorianoguerra]

When you extract the one ☝🏼 before the last one, check your video it came out upside down. If the video is correct you had inserted #5 upside down. Check out your video.

[@tomashton7208]

if the face of the lifter isnt worn sometimes you can take the lifter apart and clean it,most top dogs replace the cam with the lifters, any how, I have a 2.5 four banger and just replaced the timing chain and gears, and the tensioner, and I may swap the cam for one that has a little , more lift and duration, the lift at the push rod is .265 and with stock rockers wich I assume are 1.5 which means .400 at the valve, so im look for .425 at the valve, too bad they dont have after market rocker ratios, like 1.6, which can increase the lift without doing a cam swap, by the way I usually toss the head bolts in the trash and use studs, but obvisely that is an issue with the fire wall, but sometimes the fix is a ball peen hammer or a sawz-all my jeep is a 89-90 with 100,00 miles on the odometer, and the bottom cover for the clutch is missing my oil pressure is on spot, with a mechanical oil gauge which reads 75 at start up, and stays at 65-70 at 1500 rpms when warm

[@MrTrecutter1]

on that video, I am pushing down on the valve spring side of the rockerarm on #5 exhaust lifter

[@NickInTimeFilms]

+dan porter mhmm. Sounds like the lifter is weak and won't hold pressure. see if you can push it down at all.

[@MrTrecutter1]

+NickInTimeFilms that's the thing, I can't push it down like Ive seen on other videos. i replaced the rockerarm assembly & new pushrods. when I cranked it up it idled rough but had no noise after a couple minutes it started idling smoothly but the noise came back! that's the puzzling problem

[@NickInTimeFilms]

+dan porter The only other thing would be valve spring or valve seat. seems more like the lifter to me though.

[@MrTrecutter1]

+NickInTimeFilms either a stuck lifter or I have no idea. oil pressure is consistent, plus the noise only goes away on #5 exhaust no, I can only make noise go away on that particular spot/lifter/spring.

[@NickInTimeFilms]

It's definitely Exhaust #5 if you can push down and make it go away.

[@craigfulmer5069]

I like this guy bitching at the engine parts as if they care. I do the same and good to see someone else crazy also.

[@mykecollins3255]

Ok..so mine is making same noise...WHAT IS THE PROBLEM?

You are the best.......... thanks

I have the same sound..I replaced the rod bearings in mine and she still taps ..

[@NickInTimeFilms]

This was piston slap for me. Needed a new wrist pin.

[@RLH007]

@@NickInTimeFilms just watched that video brother 💪🇺🇸

[@RLH007]

Hey brother I was going to ask if you just replaced all the Pistons and did you have to bore the cylinder (s)? Trying to figure out if standards will work

[@NickInTimeFilms]

@@RLH007 I only replaced the bad piston, rings, and wrist pin. But it was also a fresh rebuild with only 700 miles in it. Cylinder looked decent so just hit it with a drill hone to polish and crosshatch a bit.

[@bluemoone1]

Did it turn out to be a piston skirt?

[@NickInTimeFilms]

Close, Seized wrist pin which scratched up the skirt

[@bluemoone1]

Ahhhhhhh, have had four 4.0's bite the dust, three were from cracked/broken piston skirts the fourth was a cracked head, luckily they are easily rebuilt.

[@revolutionday1]

The head on my WJ is nothing like this.....

[@zevenswant]

how do I calibrate the balcines .?

[@ryancrouch2077]

How did you do the alternator where the ac use to be?

[@NickInTimeFilms]

Built a custom bracket: kzbin.info/www/bejne/f2LPo5yappadn6M

[@ryancrouch2077]

NickInTimeFilms is that a Chevy alternator?

[@NickInTimeFilms]

+Ryan Crouch maybe? It's an ad244, got a whole separate video that covers wiring and install of it

[@maximusilive4theking986]

"That's a clackity clack clack"!!!

[@buildingusa9604]

Fixing cracked cylinder head is easy very simple

[@joeypitman6019]

A lot of times the lifter bores wear out, nothing you can do..

[@YankeeCherokee]

Man shes breaking in difficult. At least you know that engine back to front, and it's getting newer everyday haha. Seriously though, hat are you going to do about the exhaust manifold? I'm about to buy one and that's really made me worry.

[@NickInTimeFilms]

+Joseph McUmber Nothing I really can do. I have tightened it down, driven it for a bit to warm up, then tightened it again so I'm hoping it's sealing. I'll just keep checking on it but nothing I can do about the warpage. I guess I'll just have to hope all the carbon seals it up, lol

[@YankeeCherokee]

Lol. But man that sucks. Is there no warranty? Maybe you could make a shim for it. Worth a shot.

[@NickInTimeFilms]

+Joseph McUmber I'm sure a new one from the company would warp too, you get what you pay for, I wasn't expecting much for $108. haha. I've thought about maybe cutting the stiffening brace at the bottom so the ports can flex more, but I'm not sure if that would fix my issue or just make it worse. Unless it comes back or gets worse, I'm just going to leave it.

[@YankeeCherokee]

Haha whatever floats your jeep. Can't wait for the next video!

[@NickInTimeFilms]

+Joseph McUmber Me too, that's when we can finally get rid of this nightmarishly haunting sound for good.

[@matt_wiggs47]

and it could possibly be your torque converter bolts backing out

[@NickInTimeFilms]

+Matt Wiggs And I did check flex plate bolts along with tons of other suggestions, Piston slap was pretty low on every ones thought process.

[@chrisb.1301]

Was this on your stroker or the stock engine?

[@NickInTimeFilms]

This was stroked, but it's mechanically almost identical besides the crankshaft and pistons.

[@chrisb.1301]

On one of your other videos you removed your engine and had it built stroked, is this video with the lifter install/ ticking noise from the that new built engine. Sorry I wasn’t specific with my first question yesterday.

[@NickInTimeFilms]

@@chrisb.1301 Ahh, yeah this was on the newly built stroker.

[@guerillastyle420]

@@NickInTimeFilms I think that I am running into the same issue - Did you ever contact the manufacturer regarding this?
