Hey All bought a beautiful (overpriced) Cherokee Sport with 52k, runs like a champ and gets 19-21 on hwy, was loving the truck until.............found the head cracked after owning 1 month. #^%$

Looking for a head replacement, doing a little seaching, it seems rebuilding a 0331 is not the way to go.

Alabama Cylinder is no longer around

Clearwater Cylinder is available for 450

What else is out there now folks, whats my best choice for a bolt in head?

Really want it to purr again like it does now

The Clearwater is a good choice for a replacement and yes the heads on the 00-01's were a known issue with cracking.

400-500 is the range you're looking at for a new one, and imo it's a decent price. you could get a junkyard head and get it machined, but I have no idea where that would get you money wise.

call a couple yards and have get the price for a 96-98 cylinder head. easy fix.

depending on the shape its in, you could potentially slap it back on the engine and fire it up. you'd be out the cost of the head, new gasket and new head bolts. check valves and valve seats. make sure springs are all in good shape.

Buy the brand new Clearwater head. Rebuilding a junkyard 0331 will not guarantee it won't crack. It may be the reason the Jeep is in there, anyway.

Earlier heads don't have the coil rail attachment points. You would have to fab something up.

Do it right the first time, then enjoy your Jeep.

why go through all the work of changing the head out and not go through the replacement head? seems kinda like a halfassed way to do things.

See OP. $$$

I also said "depending on the shape its in". Would I do this to my Jeep? no. You also overlooked this statement: check the valves and valve seats, springs.

Here are your options:

1. The Clearwater 0331 head comes complete and ready to bolt on. It's the easiest way to handle it.

2. You can try to find a used TUPY 0331 head from a 2002 to 2006 4.0L. When Chrysler discovered they had a problem with the original 0331, they quietly changed suppliers to the Tupy foundry in Brazil to fix the issue. The TUPY heads have the word "TUPY" cast into the top of the head between the #3 and #4 cylinders, right where the original casting 0331s liked to crack. However, TUPY heads are not always easy to find, and if you do find a used one, you'll need to get it checked at a machine shop at a minimum and may need additional work on it. So your $200 used TUPY could end up costing as much as the new Clearwater before it's over. It's a gamble.

3. You can use an older head from a '99 or earlier. The '96 to '99 0630 is a popular option because they are plentiful and cheap. However, you'll still need to get it checked by a machine shop, and the swap requires more work than the other options because:

The exhaust ports are bigger on the 0630 than on the 0331, causing some people to experience exhaust leaks with the stock '00-'01 exhaust manifold. Some swear you need a $120 adapter plate to fix it, while others say it isn't necessary if you select the correct gasket. You may be thinking you'll just swap in the earlier exhaust manifold to go with it to correct this problem. That's only possible if you have EPA emissions on your 2000. If you have the California emissions (with two catalytic converters directly under the manifold), you can't legally swap in the earlier manifold.

Additionally, your Jeep has a distributorless ignition system with a coil rail, where the '99 and earlier had a distributor. As a result, the 0331 casting has mounts for the coil rail, whereas the 0630 does not. If you swap in the 0630, you'll have to fabricate coil rail mounts.

4. Edelbrock makes a head for the 4.0L. It's $1700. Don't bother.

Personally, if I picked up another 2000, I would go with the Clearwater head. I haven't done the swap personally, but others here who have done it have said it's possible to complete it and have your truck running again on a Saturday afternoon.

Thanks extrashaky exactly what I needed. Going Clearwater. just hope she purrs and gets the mileage it does now when I'm done, The rebuilt TUPY heads are almost as much as a Clearwater. Happy Mud Puddles to Ya

abodyjoe

still with all that work you are better off going through a JY head in my opinion.. spend the money now or spend it later.

Clearwater head 445,
shop Labor 400+gaskets

Good thinking. That's where most of us 0331 victims end up. The TUPY replacement really only makes sense if you can find one in a junk yard. The 0630 swap really only makes sense if you just have cheap or free access to one, like some of the guys who have multiple rigs and lots of parts sitting around.

Good luck!

Always wondered why my buddy always had 2-3 cherokees sitting around
