Howdy JK forum,
I just purchased a 2002 Liberty 3.7 limited with 4WD and auto transmission. It has a blown motor, but only cost $500. I’ve partially torn down the engine to see what went wrong, and so far I’ve found that all the coolant is in the oil pan, #4 spark plug is broken from some kind of mechanical damage (like a dropped valve), and I found a timing chain tensioner broken on the crank to balance shaft chain. It has so many new things from the previous owner like new transmission, AC, alternator, battery, etc. that I think it’s worth rebuilding the engine. What kind of things should I make sure to replace or upgrade on these engines? I’m not super familiar with these 3.7 Mopar’s, but I know engine rebuilding pretty well.
