Greetings from the UK! Great video. I've been fixing cars for years and looking at this great American straight six engine makes you appreciate old school engineering. None of this four valve per cylinder DOHC stuff, just simple, straightforward 4 litre grunt. With a job like this it's just a case of being methodical and organised. I take my hat off to you sir!

Thanks for the clear and concise demonstration. It made it clear whether or not someone would want to tackle this themselves as a driveway project. And the recommendation for Clearwater is a jewel since there are so many out there for sale. Would love a 7 Years Later quick update.

Even though I'm not planning on a job like this on mine I still found this very entertaining and I'm watching it for the second time thanks for brightening up my day!

I may have to do my Cylinder Head soon, I will revisit this video again if and when I do it. Thanks for taking the time to share your venture with others,

saw a kid walking out of the junkyard with a 4.0 head.......now i know why lol

Thanks man, it pays to be organized, I couldn't imagine trying to figure out where stuff goes after a week of being away from it

Well done, your organization during the disassembly makes all the difference in the world. Thanks for the tip on the rearmost

Dude you are a madman. Nice job!!! You are my new hero. I've got a TJ and haven't tackled big jobs like this --- but you take all the mystery out of it and that removes a lot of fear. Thanks for taking the time to record and explain all of this. Super-appreciate it

You don't need to completely remove the intake manifold, just let it sit on the exhaust manifold so you don't have to disconnect so much stuff. The steering pump can also stay in the bracket. As for keeping track of the valve cover bolts, other option is to just take a photo from each side. I did this because I wanted to throw them in my parts cleaner. As for the lifters; it's not a problem to put new lifters on an old cam, you just don't want to do a new cam with old lifters.

Good job on the vid. You are a king of shade tree mechanics.

very well done sir and great attention to detail . ive been a mechanic all of my life and would have no problem with you working on my vehicles if i was unable to do so , good job

Thanks for the video! Julie and I just finished this on a 2001 Jeep Grand Cherokee (ordered a Clearwater head plus kit), worked on it off and on for 3+ months since I didn't have a heated shed and it is winter. Worst part of it was the exhaust/intake manifold bolts. A couple of them you can barely feel, let alone see. Within the last year, we've replaced the oil pan (shop stripped the drain bolt), rear main gasket (might as well while in there), oil pan gasket, transmission pan gasket/filter, radiator, thermostat, and all hoses. Figured we would rather invest in parts and elbow grease than have a new vehicle payment.

You could coat your cylinder walls with motor oil to help prevent rust from the open atmosphere if you feel foil and plastic wrap isn't enough.

Someone else already asked this but no answer....what where the things "You had to run to the parts store for things you didn't know you needed?" This would be great info to know. Thx for the video!

Really great video I just ordered my cylinder head from Clearwater; also great people so far. This is informative and I will be checking back over the next two weeks as I swap out head in my 2002.

I truly admire you for the work you did on your 2000 Jeep.

You did a great job! Video was very informative. Thanks for Sharing!

Damn right that 4.0-liter straight six is indestructible! That's why I've kept my '88 all these years after buying it brand new.

Thanks for the tutorial man. Theres no telling how much trouble you saved us stubborn autodidacts.

I'm doing one right now and decided to pull the head with both intake and exhaust manifolds still attached while using a hoist. I took the project over from someone else and thanks to your video I'll be able to see where a few of the already been removed parts go. Thanks for sharing.

Very nice video. Just the facts and no useless garbage...just how it should be.

Nice Jeep glad to see you are keeping her on the road. The only vehicles that are greener are the cars from the 1950 in Cuba people just don't get what it takes to build a vehicle. I get so aggravated at people that have reusable grocery bags but drive a throwaway Prius. Sorry about preaching to the choir :) . Really like your cardboard trick also, I cannot tell you how many times I said to myself I will remember how they go. Ha.

Your welcome! I posted this mostly so people would have a good idea if they wanted to do this or not. Compared to an engine ohc, it's blindingly easy!

Very informative video. Thank you for taking the time 2 make this Fearlessfront as it's was helpful to prepare plus has overall common sense tips: cardboard boxes used to keep track of hardware locations, old hose to shim a bolt and a jack to raise the exhaust. I drive a 2003 Wrangler with the same engine (since new off the showroom floor) and I hope it won't be affected as well. No issues as of yet as it's at 108,000 miles and drove from Anchorage, AK to Houston, TX and back without issue.

Best video on KZfaq. LOL Thanks.

i"ve been a mechanic for 23 years doing major repairs and you did a good job but i would just like to add a couple things for any one doing this job when installing new lifters (hydralic) you should always prime them you can skin this cat a couple ways soak in oil take a push rod and pump till hard or a oil squirt can pump in hole especially positive stop rocker. if u don"t prime they bottom out and damage internals . chase all haed bolt holes to get proper torq

Good for you! I felt as if I was sitting shotgun on the test drive. I do all the work myself on our 4.0 TJ Rubi. But, I have not ever done anything on this scale. I know I will have to down the road and seeing your video sure gives me a boost of confidence. Thank you for posting!

Nice video! Very informative. This is probably the best how to video I've seen in a long time. Thanks!

yeah, that was probably a re-man head... I actually orders one of those first, got it, and noticed the same thing you saw... welded crack... thats how they all "fix" them... it's bullshit, I wasn't about to put it in my truck... So I ordered the brand new (re-enforced) casting from clearwater. So far so good..

I didn't hear any cussing at all, you must be doing it wrong! LOL Thanks for the video, good stuff.

Thanks for the video, helped my father and me replace the head, head gasket, etc. on my XJ

Really good video, i like the fact that you call it straight, and make it sound pretty simple. Just like a good teacher

"developed a lifter tick"- so you mean every 4.0?

What was the total price tag ?!!?

Todd, thanks a bunch for the video. It really helped in repairing my '97 TJ. Still got misfire codes, but the head job itself came out fine.

Great vid, super helpful and easy to follow. Steady cam work and decent audio appreciated.

13:18 You deserve that drink :D

i would have replaced the exhaust manifold, the stock ones are cheap and crack easily

Great Job, man! Super helpful! Thanks for making this for all us Jeep 4.0 owners!!

I loved the idea of putting the bolts on the strip of cardboard. I had to replace my rear main seal in my XJ and didn't think to do that with the bolts from the oil pan. Long story short, I mixed up the different bolts and had to take it to my mechanic to finish it up. Great video!

CAN U CHANGE LIFTERS WITH OUT CHANGE A CAM?

thanks from russia

Pretty good video. I just walked it for the hell of it and it was a more in-depth a lot of the other videos I have seen so congratulations, you may well have one of the most in-depth for their Jeep head gasket replacement videos. I'm sure it will help some newbies and young Bloods, and a very good thing to show them how to organize bolts and studs and such I would also do the same with the rocker arms and pushrods because they should always go back in the same place as well. Only tip would be tell people what size socket you are using on each other the bolts or studs and if they need a deep well like the head bolts. Anyways, good job.

Nice video! I'm getting ready to dive in on mine and it was just nice to see someone go through the process. Thanks for your contribution.

got a 91 xj going to replace the head. never have done one (motor yes head no) wondered how it was done. really nice video good camera views and give me alot of good knowledge to get started. the plastic wrap and tin cap was smart, ill remember that trick. thanks zeke! p.s. if you do a lift kit...go with rough country and if you have a friend thats a vet ask them to help out. they give discounts to service members.

Thanks man, those little steps make life a lot easier on re-assembly

I don't know to much about engines but I do have a passion for cars. I want to learn about engines so I can work on my own L6. Thank you for filming this video I learned a lot.

Dude! Great job!!! I'm about to replace lifters on a 2005 4.0 wrangler in a few weeks and your video was great insight...thanks so MUCH for the effort!

I just did mine and the only difficult thing is torquing down the exaust and intake manifold. I cant believe it, putting the head is the easiest if you got the torque wrench and specs. Thaks fearlessfront you video helpped me alot

That's an awesome idea with the holes poked in cardboard to organize the bolts. I learned a lot watching your vids. Thx

I am from the snowbelt as well. You can't beat these XJs. Never had newer than 97 so haven't dealt with cylinder head issues but all have had awful rust. If I find one from down south I'm going to snag it. The last one I had was a god awful pain in the balls to work on with every suspension /frame bolt being frozen... makes every job take 3x longer than it should. Thanks for sharing the vid!

Again, thank for the vid! I knocked out the job in 2 short days. Very Easy. it looked like the head was previously replaced because it looked much newer. My lifter in intake Cylinder 2 was completely worn through! The old XJ runs like a beast now!

Nice Job!!! I'm looking at getting one of these jeeps with a 4.0 - nice to know they are backyard mechanic friendly!

Awesome! Just had my head gasket blow and this was the only video I could find that helped! Well done. Thanks!!

Hey thanks for the video man, I appreciate it. Got an 01 WJ 4.0 with the same problem, just starting now after 176,000 miles. This video helped me get an idea of what I've got to do, now just time to get the hands dirty.

im researching how to install performance cylinder heads on my mustang and this is really helpful thanks for taking the time to make this video

Great video. I've owned three XJs, traded them each off at 200K. I really miss my 2000 Classic. It had the dreaded 0331 cracked head. I'm a WK guy now.

Great video. My 4.0 broke some piston skirts and I am in the middle of the tear down. Your video helped thank you. John

Thanks for this video, it actually helped me in fixing my car. I have to say that you are very brave to take up that big job.

sweet job my friend, i am doing the same project, Your video was very well done and helpful. Thanks for taking the time to film and share it.

THANK YOU, i used your video as a guide and things i needed to complete changing my head on my 2000 jeep cherokee, again thank you

Congratulations. Mine is a 1998 and i believe it is in need of a new cylinder head. Since I am from Brazil we have cheap labor but expensive parts. So I will probably have mine rebuilt. Great video, great job.

Great video, very helpful. My 01 has a good head (so far - fingers crossed) but if I have to tackle this, your video will be a big help. Thanks!

This was not my case at this moment, but I did enjoy your video, your creatively with cartoon boxer "Eco-Friendly catch my attention with your organization with the good energy explaining the most you can to us. I appreciate your willingness. I would love you would visit my Cuban community in Cuba and share with them some good car knowledge. You see my people fix everything out of not having many sources lol

From what I've gleaned off the Internet, the 0331 casting cylinder head is the one that gives issues and was produced from 97/98-02, with and without the coilpack mounting bosses. After that, Daimler/Chrysler Jeep switched to a revised 0331 casting made by TUPY. This second version of the 0331 is reinforced in the area that was prone to cracking between cylinders 3 & 4. The TUPY is equivalent to the Clearwater H-D casting that you used. I hope this helps others & again thanx for the video! -G

absolutely awesome the way you organized your stuff on carboard, I do the same thing

great job and a great video; Im going to replace the head on my 96 XJ next week and your video has really been useful, thanks!

Nice Job,Doing the same thing on a friends jeep,With a cam and lifter's though.Did a couple smallblock chevy's when i was a kid so i watched your post for a refresher,Thanks

Great job! Also great camera work and editing. A skill that is sorely lacking with other videos.

Thanks! I'm not doing the exact same job but close. I have to replace a piston today so similar tear down. Never done it before but the video gave more confidence!! And a great walk thru!

Thanks for the vid man. I have a '96 with bad valve springs causing multiple cylinder misfire. Can't wait to pull it apart.

great video man, I'm about to have to do this exact job on my 2004 Cherokee. thank you so much for posting, I'm definitely subscribing

fantastic job - you have SO MUCH more patience than i do - kudos

I know I'm going to have to do this someday on my 2000 XJ. REALLY glad I found this video! Thanks man!

Fantastic video! I have a 0331 head on my 01, and I know that there is a possibility that this teardown may be in my future at some point (hopefully not). Love the tips and the detail you go into. Hope she's runnin like a top still.

yes I do, i'm putting up a vid of that soon. it's really cool the way it hooks up

thank you so much for making this video. im about to rip apart and put a new head gasket in my 94 4.0 wrangler. i have a dealer manual but man did it help to actually see everything. right on dude!

I am about to do a head gasket and this video really helped my confidence on attempting this thanks man.

I have a 2000 myself with a similar problem. This vid helped tremendously. Awesome!! Thanks.

This video is exactly whats wrong with mine. Now I know whats parts I need and what to replace!! This video is awesome. Now, to actually do it is another story. Thanks for the vid!

Good video bud. well explained and detailed. I saved it into my how to archives for my 4.0 engine fixes. I will probably still pay a buddy to do the head on my TJ because of my low patients level. I look forward to seeing more of your videos.

Ok thanks! My old 94 4.0 didn't have the alignment pins...so I got my dad to help and we just kinda slowly lowered it on. It was pretty much aligned on the first try...torquing down the bolts took care of the rest. Thanks for the quick response!

thanks man, I did put some oil in the lifters, but they sat for a week b4 I replaced the head. Thats why I did the false start, to get some oil moving. And I did put motor assembly grease on the bottoms of the lifters. I would be crazy not too! lol I've honestly never heard of re-torquing a head, but I'll be replacing all the rocker arms next weekend, so I'll check them to be on the safe side. Thanks for the tips!

Great video. I'm actually looking at buying a 99 Cherokee that has a bad head, so this video let me know just what I was getting into. which is a good thing because I was also looking at another truck, and the jeep seems to be the easier (and probably cheaper) one to replace the head on. again, great video!

Really appreciated some of the tips, the cardboard for the head bolts and lifting rods was great. I'm doing exactly this procedure right now, and am just about to put everything back together. Was wondering what those items you said you had to make parts runs for that you didn't know you were going to need. It's crazy far for me to get last-minute items, so I'd like to get them before starting if possible. Thanks - great vid.

thanks man this really helped me out to replace the head gasket in my 94 jeep you save me a pretty penny

Nice job and really good video. I got a '02 Wrangler TJ 4cyl and I have been as deep as pulling those intake and exhaust manifolds. Jeeps can be a pain but at least you can work on them!

Nice job, man! This just happened to my jeep, good to know it wasn't as bad I thought it would be.

Thanks so much for the post dude. I'm a first time XJ owner and it just so happens that I have a '00 classic that has the same "diesel" ticking sound you mentioned. As I don't have much experience with 4.0's yet I just sort of chalked it up to cold weather starts (and it's 120k miles) since I live in the midwest, but I've been noticing subtle things over time that are slowly pointing towards the typical head issues associated with the '00's and '01's. I bought the jeep primarily because, well, it's a 4.0 jeep why wouldn't I buy it? But secondly I bought it because of the dudes like you that actually give a damn about these machines and actually go out of their way to help each other out while keeping these babies running! I'll be following your videos man, thanks for the detailed info.

Wow man that was great. Really helped me out on seeing what kind of a job this is to do. As you said not really that bad just time consuming. Thanks

Good job man. 99 Xj here about to dive into the exact same job with a salvaged 96 cylinder head.

Awesome video. I miss my XJ but its funny I use to own a 2000 TJ that I swore had an issue with the head or gasket and now just learned the 2000 4.0 head issue. Makes a lot of sense now.

Awesome video I’m changing mine now, really hoping it’s just the head gasket but we will see soon!

It sounds better now then before,great job bud.

Great video! I am on my 4th Cherokee a 2001 with 300000 miles on it. This is next weekends project, minus the new head. I have had to do the lifters on all my previous Cherokees around 150,000 miles. Cant believe this one went so long!!!!!!

Very brave and well done. I know that in a few years I'll have to pull the head off my 83 4.2L but I'm just glad I don't have so much clutter in the engine bay to mess with. I tore a 4.0L head off a 92 Cherokee and the water jackets are sealed. I just need to get an area to work and get everything nice and clean first. :)

This video and Producer have helped me out a lot, Thanks man keep it up!

great job! Not many people would do it like this... they'd just tear it apart and slam it together. But you didn't do that. I give props dude.

Getting ready to do the same thing on my 2000 Cherokee! Thanks for sharing bro.

my parents had a 1984 AMC J-10 Jeep fullsize pickup with the Straight 6 when I was a kid.. I would kill for one now... A lot of good memories with that truck...
