AllanD, This was an old thread bumped for similarity of symptoms.
Ray, the consensus around here is that your $ would be much better spent dropping a 4.0 in there instead. Good luck with your rebuild though.

Of course after buy it I drove it home 40 miles away, on the way it drove fine for the first 10- 15 miles then started loosing power. Dropping cylinders as it went. I only ran about 50- 55 mph and after getting to town and the first stop light, OIL Pressure dropped to nothing and just bounced the kneedle. Missing out and fluttering. About 3 lights later, smoothed out and ran good. No miss, power came back and the oil pressure was in the middle as before.
Went home, Changed oil and filter, started it and the tick was gone.
Drove it around town and ran okay.
Took it back on the Hiway and same as before, power loss etc.
Went home hooked up a oil gauge the next morning when it was cold, 25 psi at idle. NOT good. Ran it down the road, 5 or less psi at idle.
Ended up tearing the motor apart. The guy had bandaded the bottom end with mains, halfa.. and the thust bearing, cam bearings, cam, crank, rod bearings everything junk.
Pulled the motor, am rebuilding it now. New everything, maybe a little over a $1000 in my rebuild! SUCKs, but what can you do! Any comments appreciated. I am new to this forum, so 4X4 1989 help will be appreciated.
If at first, you don't succeed, RTFM.
