Hmmm.....?
Certainly, I would have.
I seem to remember doing that.
But.  Did I?

Crap.

OK.  Let's think this out.
I THINK that I used all the parts when putting the engine together.
I KNOW that I did NOT perform the extensive re-torquing that Lynn recommends from his experience with loose engines when
 it isn't done.

So, my course of action will be to do a tear down to reach the case bolts, and measure how much they move with a
re-torque.  Given the leak is more of just a seep on the left side, even a 1/4 turn on a bolt would probably be enough
to seal it up.  If I get an additional 1/4 turn on any left side bolt, wash the engine down, bolt it back together, and
call it fixed until I see any additional seeping to prove otherwise.  If I do see any more seeping, I'll pretend my name
is Chris and tear the whole engine down.  8*)
