Jeep Cherokee: Cylinder Head Gasket Replacement Procedure/ 0331 TUPY 4.0L ['96-'01 XJ]

Was the head cracked, or was it just the gasket?
It was, in fact, both! The machine shop confirmed the original 0331 head was cracked all the way through, but rather oddly, it cracked between a cooling jacket and cylinder 4's combustion chamber.

I fuckin love your content, please never stop making videos for the 97-01 XJs

[@theflyingguillotine3788]

Second that

[@GraceBMontgomery]

As someone who’s had to do this job twice (new head was faulty from Clearwater) listen to what he has to say!!! always keeping it real and honest WAEMID!

[@cjmcq1117]

Currently rebuilding my 99 Cherokee off this video!! You are the absolute best! Great tips and tricks they’ve all worked for me!

[@rlt7409]

I literally wait for your videos like when Rick and Morty are between seasons. It's agonizing.

[@ryanellis5902]

Bro, always love your content.. did this job on my 97 last year with the help of my brother-in-law, who is a professional mechanic. All the other jeep head videos carry on about the rocker arms needing to be torqued wile on TDC for each cylinder.. this is absolutely not required as the valves are self-adjusting. Just torque em to spec and call it good.

[@dakia7979]

As someone who has this job in my near future, thank you for a very detailed video

[@James-wo5nb]

I love it when you make these informative videos with all the background info, thats my boi

[@chipjumper]

Weaver Auto's machine shop in Suck City only charged me around $230 to hot tank, pressure test, and machine a donor TUPY for my '00. Was so much cheaper than a Clearwater head. Clearwater usually has a 6-10 week lead time unless you pay them $$$$ extra. Sometimes RockAuto has heads ready to ship with no core fee.

[@21kitkatbar]

Your content has been so helpful in my quest to rebuild my gutted MJ, keep the content coming!

[@Jayman0057]

9:10 you got me. I did read all of that

[@ccaldwell8556]

Another masterpiece. Thanks for publishing this great work.

[@MrSnowford]

Fantastic vid as always. After the apocalypse there will be nothing left but cockroaches and a fleet of XJ's roaming the wasteland all thanks to WAEMID.

[@Wrencher_I6]

Very nice video keep up the good work !!! I am a 41 year veteran tech , you can lift the head with the manifolds but that’s way to dam heavy and awkward, I take the manifolds off , I’m doing the head on my 2000 soon to,

[@classicklyjus1025]

Very much appreciate the time you put into these videos. Any job I want to tackle I always go to you first and check if you’ve posted a video on it. You’ve helped me in many situations. I truly thank you.

[@rheidtech]

Speaking of sand in your engine.... silicon carbide (sand paper) is sand... thats a nono. You need a carbide scraper. Lisle or others.. other than that.. THE BEST HEAD VID ON YOOTOOB! 🎩

[@Taco_drew]

Great video!

[@the-pezinator]

Awesome video as always, I hate that I'm going to have to do this at some point or probably more than just this, but I love seeing the process in your teaching ways, also really funny seeing the antenna hit the height limit things. Rest in Peace Shaller88 :(

[@REVAdrian]

I recomend to vaccum clean everything before spray brake cleaner. Beside that I really enjoy your videos

[@eperot]

A job l do not look forward to, but in the event it becomes necessary (and l plan on keeping my ‘99 2 door until l’m dead or no longer capable of driving, so there’s a good chance) l’m definitely using your video. Great work!

[@Wrencher_I6]

The head can have a very small crack and cause coolant loss slowly and not change the oil color. Seen it before

[@davidk7132]

Another solid video!

[@KyleSVT]

Excellent

[@ronjohnson3393]

Well done and done well ...

[@AAB371]

good job

[@TheSixxBird]

Head game on point

[@mikesymmons31]

I like to run Valvoline racing high zinc oil in my 4.0s to help with lifters

[@BenjaminStubbs]

Will i ever find out out Waemid's 331 head controversy? Will the machine shop ever tell him?

[@steveleisten1189]

NICE !

[@saxnn2474]

Wish I had this vid when I did the head and gasket! You forgot to tell them not to follow in my foot step, because you don’t want head bolts at 130 ft lbs… so far running fine tho so if anyone sees this after making a mistake, the 4.0 just doesn’t care ig. Time will tell

[@antoniotrejo9240]

Mine just blew at 110,000 lol, time to get the head rebuilt and slap a new gasket on it, new thermostat and fresh coolant

[@BenjaminStubbs]

Shaller will be missed. Good man, gone too soon.

[@jordonthompson4687]

Do you have a link for the oil cap the plastic ones always break on me?

[@MrTM-fg6zn]

Replace the head while you have it apart.

[@ToddS50]

Come visit Colorado and work on my XJ :)

[@WAEMIDIV]

what's it need, and will you pay me

[@ToddS50]

It needs the head replacement - I'm going the expensive new head route. Getting parts together for the fall. I probably can't afford to cover your expenses and paying, but with your helpful videos I'm confident I can get it done.

[@sadsniper101]

300.000 best ending

[@MaybachDay]

When you're doing the head bolts, do you hit them with any kind of PB blaster? I'm sketched out to crank the bolts out. I bought new ones, about to tackle this tomorrow.

[@WAEMIDIV]

@@MaybachDay I didn't use any PB, just bust those bolts free with the brute force of a breaker bar, they'll come out. I guess PB wouldn't hurt anything if you really wanted to use some

[@MaybachDay]

@@WAEMIDIV Okay, I'm just going to send it lol Just wanted to make sure because I soaked manifold bolts for a couple days before doing it and everything came out fine, contrary to what I've seen on other videos haha

[@MaybachDay]

@@WAEMIDIV Appreciate the videos! This isn't the first one I've seen.

[@haydenwinfrey1337]

What kind of oil do you put in your XJ diesel oil or conventional gasoline oil and do you really need zinc in your oil

[@WAEMIDIV]

I have used diesel oil, the 4.0L really likes zinc yes. But it'll run on anything

[@WAEMIDIV]

well I'm not an engineer so I dunno. I put oil in it and it runs

[@cjmcq1117]

Hey Boss, I have a 99 XJ all put back together and when I start it, it's like someone is flooring the gas causing the car to go at max rpm. Any Idea what could be the problem? I drained the fuel rail and tried again and the same RPM problem happened again. I followed your video and come to find out I did even need to take the head off as I had a hole in an expansion plug on the block and that's where I was leaking coolant. was wondering if you would be able to answer a question for me?

[@WAEMIDIV]

@@cjmcq1117 sounds like a major vacuum leak, like the intake isn't seated properly. Too much air is getting into the engine somehow. Maybe you broke a vacuum line or the manifold was not properly torqued. I recommend watching the manifold video

[@cjmcq1117]

Ok thank you! I will check that out.

[@cjmcq1117]

@WAEMIDIV I watched your manifold video and went through and took it off and careful reassembled the manifold and up. I put heavy duty tape on the ends of all of my vacuum line and it runs great now! Thank you very much. The only problem I’m having now is coolant leaking from the radiator cap. I let the jeep run until reaching 210 and cool down, filling up coolant until I used all 3 gallons. I took it for a test drive and parked it, letting it run for a little and I had coolant leaking from a brand new radiator cap. Any idea why this would be?

[@cjmcq1117]

@@WAEMIDIVI ended up watching your video and it helped! I ended up taking everything apart and reassembling it. I also taped the end of the vacuum lines just to be sure and it fired right up. I do have 1 problem with coolant coming out of the radiator cap. Would you have any idea what that could be? I was thinking that the over flow line could be jammed. Thanks again!

You live next to my neighbors too? God damn kids … all six of them born again Christian home schooled, which home schooling as far as l can tell involves letting all of them play outdoors screaming all day long driving me nuts any time l’m working on one of the cars….or just, you know, trying to relax in my back yard
