I am sure everyone knows about the 2K Cherokee head cracking problems. Well I have one. I can see coolant seeping between the 3 and 4 cylinder when I look down through the oil fill cap when the engine is hot. I called Chrysler and they told me they have never heard of a problem on this model year and cracked heads. I was like "yeah sure, just read on any Jeep forum and you will find out how bad it is". Anyways back on subject. What new head should I get, casting number wise. I did a search and one of the guys was talking about the new casting 0331 heads being better. How do I know I am getting a newer casting? Where is a good place to get one that will not cost me an arm and a leg? Where can I down load a service manual at for my 2K Jeep Cherokee? One last question, did they ever find a fix for the low oil pressure while the engine was hot issue I have and have been reading about? Was it head related also?
If I needed a head I'd check the scrap yards for one that had been wrecked and spend a few bucks at the local machine shop to have it checked before installing it. I believe the cast number is actually on the outside of the head, someone please correct me if I'm wrong.

So what years do I need to look for. I know there are wrecked Jeeps here in my area but I do not know the condition. I have checked Ebay and found a 0331 head that is advertised as being "beefed up". Was that casting number redesigned or fixed? I have the coil packs on plugs so I need a head with the coil pack mounts that are on my head so I can bolt everything down.
Replaced oil sender, oil pressure did improve but not what it should be. The Jeep was obtained so that a family member who is elderly and without a vehicle could have it. I picked it up knowing it had "minor" problems and have been reading up on the huge amout of head problems with these years of Jeeps. I owned a 97 GC Laredo and it was a great car, but this one sucks.
Now I did make a few calls today about the head and spoke to three different companies about the head. They all said that 0331 casting was crap and cracked faster than a dropped Saltine. They all said they sell two or three heads a DAY for that casting. That my friends is alot of heads being moved.
I just do not see how Chrysler cannot think there is a problem.
I feel your pain on the 2000. Chrysler knows it is a problem but they don't give a crap. Much like the HVAC problems in the WJs and all the crappy Chrysler transmissions, the noisy AL D44, etc.
Did you call Alabama cylinder head?
I would say just throw one of the improved heads on and call it a day, but the low oil pressure is pointing to other problems. Unfortunately, since an elderly person will be driving it it may be best to take Vaj's advise and replace the head and sell the jeep.
Yes, I did call Alabama Cylinder Head and they told me it would be a few weeks before anymore were in stock, sold out at the moment. He told me they sell them everyday. He also said they make their own with thicker spots between the prone crack areas, so I will most likely go with that one so I am not replacing it later. I know some said fix it and sell it but I just cant sell it knowing something might be wrong with it, unless I sell it for cheap and tell the next owner about all the problems.
