Still haven't figured this out. The oil pressure issue went away when I switched back to a plain ol' M55 pump, but the smoke won't stop.
So far, I've done these:
Had .100 milled off the ends of the intake, because it was squeezing the rtv out and ending up metal to metal. Now it sits like it should.
Switched out the Viton valve seals for Teflon.
Still smokin'.
Today I pulled the pistons, and there were no rings upside down or anything stupid. Stuck #6 back in upside down with just the oil rings on it and pulled it with a fish scale...had 10-11 lbs of drag. Now I'm out of options, so if anybody has more ideas, lay 'em on me.
