Re: Rear Main Seal Question
I sure wish you guys were right about the valve cover gasket, but I replaced
it a couple of months ago. This engine has 188,000 miles on it and it's
definitely the rear main...flowing like the Exxon Valdez. Do I absolutely
have to pull the tranny or can I snake it in with the trans in place? Thanks
for your replies!

Re: Rear Main Seal Question
It's a two piece seal. It is relatively easy to replace, but seldom fails.
The actual problem is most likely the valve cover gasket. Would you like to
know how I know? I hope not.
The engine is raised on the front. Oil is pumped to the top, and flows down
the pushrods back to the crankcase to start over again. While the oil is
flowing down, it also flows to the back. The gasket likes to break in the
back. The gasket is about 1/4" thick. The hole that results when the gasket
breaks is however much the gasket shrinks wneh it breaks x 1/4" (or the
actual thickness of the gasket). Oil flows out this hole, runs down the back
of the motor and off the bottom of the bellhousing. It looks just like a
rear main. Pull the valve cover first.
