I was not thinking when I posted its going in the 2000xj its a 96 engine only had about 70,000 on it however the guy I bought it from left it out side under a tarp for a couple years and some water got in one cylinder. The engine in the 2000 has 210,000 on it sounds like a diesel when you start it I overheated it (BAD) when the head cracked there was no water in it at all when we got it towed home. I have ran it for a about a year now all we did was put the 96 head on nothing else and still runs good but is getting quite loud uses and leaks oil. I could most likely just throw it in a run it and be okay. I just want to hone the cylnders and put new rings in so might as well do the bearings. I am not doing a complete rebuild unless something inside looks bad.
