Hey Guys,

I have won the dreaded 0331 cylinder head sweepstakes on my '01 xj. I have been reading forums forever and just have one question.

I noticed that they fixed the 0331 run on the later grand Cherokees. Can I swap mine with a later 0331? If not I am looking at using Clearwater to just get a new one. I would love to swap but cant seem to find if they are compatible or not.

Thanks

Yeah you want a Tupy stamped 0331 head I think they started using them late 03 or early 04. Which makes me chuckle since that's my last name..

awesome. So I can just snag one from a yard and plug and play? That made my day.

You have to verify with the yard that it is stamped "TUPY" - if it is not, then it is just as susceptible to the crack as your current head. I called many yards in my area looking for one but all they had were unstamped 0331s. I got my head from National Head Co. - $435 and great customer service. Just put it on this past weekend.

Did you go with the more expensive of the options? It is showing $440. They also have a $314 option.

The website shows $440, but when you call, it's only $435 (they're re-doing their website).

You want the new head (more expensive) since it has been beefed up to fix the problem. The cheaper version is just a reman head that is just as likely to crack again.

Thanks John, I just ordered the new one from the site. I appreciate the help!

I recently did this swap on my '00. If you have any questions feel free to PM me.

Anyone in the Nj area able to help me do the same swap? I really don't wanna pay the 700 for labor but not sure I can do it myself.

NJXJ, if you have the garage, and tools, and basic mechanical knowledge/ability, and arm yourself with an FSM, Haynes manual, and some reading/video watching, it's perfectly do-able.

The biggest job I had ever undertaken myself in regard to auto-repair was changing brake pads/rotors, and I was able to complete this job over a weekend, taking my time, asking questions on here, and being very meticulous with everything.

Unfortunately, I'm absolutely swamped the next couple weekends, but like AZ, will assist via the inter-webs whenever I can.

I did mine 2 years ago and the only place I needed a second pair of hands was to help mounting the 80 lbs lump back on the engine. Other than that everything else is doable with just basic hand tools. FSM is a must though and you remove a lot of bolts/nuts with varying sizes so organization is key to success. You can also take pre/post pictures to keep you straight. Having said all that, I'm sure this is not a task for everyone and I can easily see why someone may rather pay to have it done.
Whereabouts in NJ are you located?
