>presence of O2, and that should not change significantly with the burning of a little bit of oil.
I'm not sure that's true, David. When this happened to me the rapid breathing of the pilot decreased the 02 level in the surrounding area significantly. ;)

When I got back I had a cell phone message from someone who saw me pass over billowing smoke - the message asked me if I knew I was on fire. Very helpful. :)

I had about 4 qts of oil left when I taxied back to the hangar.

I blew two stock turbos and one hybrid before giving up and buying the T04. The engine rebuild after the last blown turbo cost almost as much as the new turbo, not to mention the underware.

Maybe it's just me, but I think that between us we've proved that stock, or modified stock turbos just can't handle the stresses.
