Woof. Still considering yourself "lucky"? 

So you're thinking oil getting pulled up past the rings and then getting sucked out the intake valves into the plenum?

Hard to do a leak down test at BDC except when the cam is out.

Perhaps fill chamber with oil or diesel and use a dipstick through plug hole to measure drop over a day.

Yes - still lucky to be fortunate enough to play like this . And yes oil was getting by the rings somehow. My machinist is an old racer and has seen everything . He actually went thru the same thing . A ring defect was allowing oil to contaminate the combustion mixture . THe fact I’m pushing 225 psi amplifies the condition I believe . 

Im going to get some larger pistons and salvage the engine - AFTER I finish and get the 3.2 running .

Damn! That bites, I know the feeling well, sometimes you just miss stuff.  But you're right, we are all lucky enough to be able to play like this. Thanks for showing us warts and all, you don't learn much from perfection.

Don’t mind sharing my mistakes . I’ve learned reading about others too. It would be easy to blame my cheapy Ebay Perfect Circle old stock rings that gapped bigger than stock, but that’s not the real reason. Can’t expect rings to seal on a sketchy bore. In the end, I’m glad to know why this stuff was happening and not blame it on cheap parts

Yeah, thanks for sharing all this stuff. Knowledge is certainly a type of wealth.

I agree. No sense hiding our failures. If everyone thinks we never make mistakes, who are we kidding! I’ve never learned anything doing it perfect the first time; mistakes make us better at what we do....
.... and I’m getting “better “ all the time...

 Confirmed by the gentleman who made WD1 - WD39

And the guy who made preparations A through G.

They were complete failures.

I know, and I agree completely. I was just making a joke about the nickname your mechanic coined said some time ago.
