Re: Crank seal replace - 90 Cherokee
Hi Jeff,
Ditto, I don't know why we all have jumped to that concussion, the
last time for me on my Bronco it was the oil sending unit, maybe that's
why we've never seen a rear seal leak, we keep replacing them before
they fail.

Re: Crank seal replace - 90 Cherokee
Once I thought it was my rear main seal because i had sucha big leak and the
back of the head was clean. It ended up being a bad oil pan gasket at the
back. I hit the pan earlier and deformed the gasket surface. While I was in
changing the pan gasket, I figured what the heck do the main seal.
The very hardest part of the rear main seal job is removing the factory
paper gasket material from the block. It took me 6 hours of hard labor lol.

Re: Crank seal replace - 90 Cherokee
Hi CRWLR,
I am only sharing experience also.
A couple of years ago I had a severe oil leak and also posted here for help.
And rightly so, it was recommended that I check the VCG. I tried to explain
to the group that, what was coming from the top of the motor was not nearly
the amount that was coming out of the bell housing. As I posted earlier, to
me, it was easy to distinguish the difference. But I changed the VCG anyway
because it was easier, but the drip... drip... drip, still persisted. After
changing the RMS, the problem was solved. I now can actually change my oil
rather than just feed it through.
Fairly common enough:
http://jeepin.com/features/rearmain/index.asp
http://www.neow.org/rms1.html
http://www.bc4x4.com/faqs/yj.cfm?cat=5&faqid=40
All I am saying is, check the VCG but don't rule out the RMS... it's easy to
tell the difference:

If the engine is oily enough that you can't readily determine where
the leak is, and since the rocker cover gasket is so easy to do, I'd
start at the top and work down.
The gasket isn't that expensive and it never hurts to renew it, even
if it's not the source of the leak.
