Ernest,

Did you do the rebuild?  If so, did you apply RTV on the lower portion
of the housings per the assy. manual?  I'm talking about the section
of rotor/side housing that is common to the oil pan.  If you don't put
RTV in this area, no amount of re-torquing will get it to stop
leaking.

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*)
