Well, I'm with you - do the retorque first, that may fix the seep.  IF not then I guess other alternatives will have to be take, Chris {:>)

Sounds like progress, Ernest.

However, I'm not certain the equation of oil spitting to power.  The oil
pressure should remain fairly constant from 2000- above rpm.  Unless you
are referring to perhaps the plates flexing more due to the increased
power?

I think re-torquing the bolts would be the first step - who knows that
might fix the problem.

I presume you did place the "O" rings over the alignment  "tubes"
between the plates that carry the oil when you assembled the engine?


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*)
