I have an 85 CJ7 with 167k miles on the 2.5L engine. I was having timing problems so took it to a mechanic friend to help me set it. After we set the timing I got him to drive it and see any other problems he might find. Long story short the bottom end in the engine is starting to go. In other words its knocking in the bottom of the motor. Now to my question, I wasn't expecting to have to replace the motor so soon so I haven't got very much saved up. I may have a 2.5L with 76k miles available in my price range that is the exact same motor I have now with a lot less miles. Should I just replace it with this engine since it will be the closest match to what I have now or should I look for something better. I'm not doing very much in the mud and since I'm in south ga I don't get much in the way of rock climbing and with what I do with it the 4cyl in plenty engine for me. The only other motor I found is a 6cyl with the tranny and ecm but no wiring harness. If I go with the 4 cyl what kind of cost am I looking at vs the 6 cyl. Thanks for any responses. Also what about rebuilding the bottom end as far as cost and whether I should.
