It has come time to either rebuild or replace my 4.0 for my 93 YJ. It is using excessive oil and when I changed out my rear main seal a while back, I recall finding sizable metal pieces in the oil pan. There is no oil at all where I park the Jeep.
While doing my search, it appears that the pistons/cyclinders have gotten worn past tolerances. I don't appear to be burning any oil, so I don't think it is my valves going out.
So, my delima is this. Do you think it is better to try and rebuild the 4.0 with 163K on the clock, or step up and look into a remanned engine with a warranty? Like everyone else, my budget is tight. I have access to all necessary tools and knowledgable people to help me out. I just dont want to do a rebuild if it actually needs more to make it right.
Thank you in advance for your time reading my posting and any responses you may have.
