So you guys have been helping me along with my low oil pressure woes, so I thought I'd share the rest of the story. I bought this old CJ and decided I sneak up on the resto, just in case it turned out to be bigger than me. it took 3 years but we got all the rotating gear done except the engine, did the body work, it looks OK, and then decided it was time for the engine. Pulled out the old one, it was bored .80 over and was worn out, needed to be sleeved, and the crank was cracked.
After some looking I found a Willys Reman that was built as a compressor engine, it was standard bore with about .003 wear, and good bearings. Brought it home and took it to a guy, he did the valve job, compressor engines only run on two of the 4 cylinders. Polished the crank, cleaned it all out , reinstalled.... Oil pressure problems, pulled the motor and found the rear seal had disintegrated and tore up the crank, cleaned out the engine again with brushes and brake cleaner, new bearings, new rope seal, pulled the oil galleys down, reinstalled, ran it about 30 miles and found my oil pressure at idle is 0 psi again.
Took it home and dropped the center main bearing cap and Viola, bad bearings, took out the screen and let the oil in the pan settle and guess what I found? When Willys remanned the engine they painted the inside of the block, looked like it was adhereing well and it did not come off when it boiled out so we didn't worry about it, guess what, paint chips all over the inside of the pan, its spalling off in chunks half the size of your finger nail, chewing up in the pump and killing the crank. So she's coming out again and we have to get the paint out, I'm getting way too good at pulling this motor and rebuilding it. Wife is wishing I had a girlfriend
