rear main thought i nailed it but.....
She still leaks like a stuck pig. Pumps oil out as the rpms go up. I can live with a little drip but a half a quart a day right onto the exhaust is a lot.
Not sure about tearing it apart. A couple if more tries and I could just bring it to a shop
Leaks either from the rms or more than likley the pan gasket. How can you be 100% that the gasket finds its way into the groove on the rms cap?
I used the dual lip rms and the one piece gasket

theres only two thing there to leak pan gasket and rear main you said you have done these and you sure it motor oil right
Yea. I'm questioning weather or not I got the rear part of the pan gasket seated right. There is a groove in the cap. How can you be 100% that you have it good to go

i noticed the same thing when i installed mine a while back i added some rtv to help seal if off.. to check just wipe down the area that u suspect the leak is coming from and while the jeeps running get under and see if ou notice anything.. I dont know but it could also be the oil filter housing. i remember mine was leaking from there.. and dripping down onto the exhaust.

jw wondering how u took the old one out? when you took a little screw driver or a little pick to get the top half of the seal out did you hit it against the block at all. if u did it could have scratched it and then it will leak

Yea this sucks, I just did my RMS myself on my 01 and leaks worse then it did before!!, this aint my first RMS on a 4.0 Jeep either so I am guessing I buggered up the rear of the pan gasket, was a real PITA doing it from jackstands and on a stock height Jeep. will be redoing in a couple weekeds but this time I am going to undo the motor mounts and try to get an inch or so lift out of the engine THEN put it on jackstands.
Other RMS jobs have been a 1990 Cherokee 94 YJ and a 95 ZJ, guess I have a 75% success rate.
