Amen to that!

I spend way too much time trying to get the rear main seal "perfect" - using a variety of chemicals and such. And I still get a leaker from time to time.

I think an FE is the only engine that you assemble with nails...

I cannot really comment on the amount of leakage or the reasons - that stuff is nigh unto impossible to isolate sometimes even with the car in front of you, much less over the internet.
