there is a large thin o-ring that goes inside the flywheel..
right where it bolts to the crank.   Those get hard and leak.

the red, or red-lipped rear main seals are the only ones to use.
The all black ones get hard in a couple of years, and don't seal that well.

it's imperative to put lock tite on the flywheel bolts as a sealant .
otherwise oil will leak out at the flywheel bolts.

the felt pilot bearing  dust shield..
I have seen 'too many times' where the little metal ring that keeps it
in place in the flywheel is missing ..
so someone puts it together with no pilot brg dust shield.
And the pilot brg fails early.

lube the heck out of every moving part in the cross shaft and TOB area.
I have seen tons of those installed bone dry , which does not work very
well long term.

anyway ..
do really careful good work.
it's not just 'bolting in the parts.'
