Chris,

Well, at least you're redeemed in your decision to pull the engine down and
investigate.  I'm sure Lynn will have some comments to make regarding the
condition of the front main and thrust bearings.  My suggestion is to
reassemble with new parts and carefully measure the e-shaft end play.  My
guess is that the pieces of thrust bearing probably caused the damage to the
main bearing.

Also, pull your oil pump and check it carefully.  If not in spec, replace
it.

I'm curious, how do you remove the rear counterweight?

Mark
