Ed,

"Foaming oil at block vent tube at over 5000RPM" - although this is
fixed, what did this turn out to be exactly?

I've seen this before and have wondered if it's a crankcase ventilation
problem in general.  One time I had one of the crankcase vents (the one
on the bottom of the factory oil filler neck) plugged up and had some
"interesting" results, including my oil pan to block sealant bubbling as
well as pretty cool James Bond 007 smoke-screen out of the exhaust.   
The only other time I've seen foaming was associated with an outer water
seal dripping/dumping water into the pan and foaming as it was sloshe
