A) Why would your TIO-540 blow everything except 6.5 quarts, while my
O-540
would settle at 8?

My engine only holds 8. I believe yours holds quite a bit more.

What??? A turbo-charged O-540 holds only 8 quarts of oil?

I thought a turbo-charged engine ran hotter, and therefore needed more oil
for lubrication and cooling? My normally aspirated, cool-running O-540
holds 13 quarts!

B) Why would any oil "blow over" at all with the air/oil separator
installed?

I can't explain this one. I know oil/air seperator's clain to stop blow
by,
but at least in my plane, the level stays at 6.5. Just empiracal data.

What the heck is the point of having an air/oil separator if it's still
blowing the oil overboard?

I'd have the installation checked, cuz something sure sounds amiss...
