We have it torn down now, pulled the crank and have the reluctor ring off. The engine (130K on it) looks pretty clean, no sludge in the oil pan, oil looks good. We will use new bearings, and we have a new '02 timing set for it. When my 02 blew, we discovered one of the chain tensioners in pieces when we started tearing it down so we wanted to start out with new timing components.

I have a 2004 Jeep Liberty 2wd, that was rolled in an auto accident. runs and drives, just with the new roof configuration its a little airy. i can get my hands on a 2002 Jeep Liberty 4x4. is it possible to take my 3.7l engine, engine wiring harness and ecm out of the 04 and transplant it into the 02? will this solve the reluctor ring engine timing issues if i transplant everything over?
