The rear main seal consists of a two-piece neoprene single lip seal. Correct
installation of the seal is required for leak-free engine operation.

Drain the oil
Remove starter motor
Remove pan
Remove pan side gaskets
Remove all sludge and throughly clean gasket surfaces
Remove rear main bearing cap
Remove and discard lower seal
Clean bearing cal throroughly
Loosen remaining bearing caps
Use brass drift and hammer to remove upper half of seal.


This is from my FSM for 1981 Jeep V8 engines. It seems to apply to both the
304 and the 360.

Re: Rear Main Seal Question
 

I just hit 280,000 Km today and check the oil since the last oil change
(3000 km). Still the same....No oil leak and not burning. i Just love my I6
, Am i the only one in this case ?
i got it a 237,000 Km and was well taken care off.
