Changing the main bearings, any of them, requires pulling the pan. Once that's
off you might as well replace all of the main and rod bearings because they're
all probably equally worn. It's always possible though rather unlikely that
the rear seal was just defective, and it can be changed when the flywheel is
off. And while the trans is out its also easy measure how far the crank can
move in a the fore/aft direction to check the thrust bearing wear ... a
separate possible (and fairly common) problem.

Hmmm, how do I know if the bearing is gone? After changing the clutch/pilot a
few years ago I immediately started getting a slight "bearing noise" while
decelerating. I haven't noticed it much lately but I am sure it is still there.
The car has 105K miles on it and started leaking about 5K (6 months) ago. I
am not a gear head and not exactly sure what changing the rear main bearing
entails. Is this something that can/should be done when I change this seal.

FWIW (and YMMV) rear engine seals don't usually go bad until prompted to by

Rear engine seal (I hope). Oil coming from the weep hole in the bell
housing. I'm half a quart down right now on the engine oil so I am assuming
that is it. I guess we will find out when we pull it.
Definitely not CAS o-ring (recently replaced) due to the weep hole leak.

Rear engine seal or front trans seal? (or CAS o-ring?)

My oil leak is getting a little worse and I think I am close to
pulling the seal and replacing it. I have had a new seal laying around forever
but have been too lazy to pull the tranny and do the work. I know how to pull
the tranny but anyone have tip for pulling the seal or replacing it? Just
looking for any little tricks you guys may have up your sleeve...
