5.2 Rear Main Project

Ok over the weekend I decided to do the rear main on my 95 5.2. It has a 3.5 IRO lift on it. First off this amount of lift does NOT provide enough room to get the oil pan off with out lifting the suspension to get more room. So if your doing this on your back, FYI. Also the biggest pain was getting the passenger side bolts out from the y-pipe to manifold, my fix I cut the exhaust pipe and rewelded it to remove the pan. Now for the good stuff I replaced the oil pan gasket with a nice blue felpro, did a high volume pump and did a felpro rear main. I followed the directions and torqued everything, made sure to put in the rearmain in the right way....btw I use to be a ASE certified mechanic so I guess I kinda know what I am doing.......and guess what????? it still leaks LOL, hard to tell but it appears to be from the rear main.....oh how I love working on these jeeps.....but I still love my ZJ.

Think I'll just keep the ghetto drip can under the ZJ

I have read that sometimes it's hard to get the gasket to seat without getting pinched. Not a fun job.

Give it a few days. My 5.2 rear main seal leaked for a day or two after it was replaced.

The seal expands a little? I think I remember hearing that. Forgot about it though.

I really hope this is the case, i dont really understand the physics of the seal expanding but i hope so, i originally had syntetic quaterstate in it and drained it and put in conventional penzoil, hopefullt it will seal up.

The last RMS I did leaked for another 2 days after I did it. I was ready to junk the jeep I had enough. Lol

After two days it stopped completely. And yes it still had oil in it haha

Mine stopped leaking immediately after I replaced it on my old 98. Also changed out the oil pan gasket too though, so dunno.

I don't know if it expands a little or maybe smooths the rubber after a few thousand revolutions or what.

I have to do the RMS on my new to me 9r. I won't get the blues this time if it leaks for a few days.
