It's sad day when a 4.0 dies. and today is no different. Cash for clunkers claimed far to many Cherokees, and most where still in there prime.
Overheated My 1992 Cherokee today. In the process some serious damage was done. :explosion It's fighting to live, after it cooled down I didn't see any signs of coolant in the oil, the Jeep did start, but bit of a clanking and rough running. later as it cooled down it would start to quiet down. Oil pressure steady at 40lbs at idle
It still ran rough, like a couple of plugs where fouled out. Plugs swapped out for fresh, and they where worn but no signs of oil fouling. still ran rough sounded like a an exhaust leak, perhaps I cracked the header.
Run the throttle up slowly to see how everything sounded, engine smoothed out, no signs of missing.
decide to take the Jeep for a quick trip around the block, by now the temp gauge was at normal operating temp. The Jeep is lacking power, and I start to hear some noise. rattling and light knocking, Limped the Jeep back home and shut her down.
If not for the noise I heard I would chalk it to a blown head gasket. after all the oil pressure is decent... The question now is how much time do I spend trying to figure out if the 4.0 can be saved? the Jeep is a 1992 with 214k on the clock. The Jeep WILL live again, perhaps with a different engine. I have regretted getting rid of my last cherokee, and I like how easy it is to work on.
