Why would anyone need a flame suit? I'm not attacking any theory, and I hope nobody else would either. The true cause of this mess still needs to be determined, but probably never will be conclusively proven one way or the other. An oil analysis is kinda pointless at this stage b/c the oil from the turbo failure is on one stretch of road or in my grass (from the exhaust idling after the turbo was replaced) and if the engine holds 6.5 quarts total, it was certainly low when the turbo line finished pumping (and I had shut it down when I realized the extent of the problem) and maybe the damage was already done to the bottom end. But I didn't run it without oil, I added more while looking for the problems intentionally to prevent it being OUT of oil as much as I was aware of. As I have said, I poured in a full gallon, and that brought it to the top of the "full" mark on the dipstick, but engines can safely operate for a minute or two (far more than this did) with only 2 quarts in the reserve sump. The first-ever oil change I did as a kid, I actually DROVE the car about a block with only 2 quarts added to it after a change. The car was fine for 100k miles after that mistake.
With this hole in the oil pan, again an analysis is kinda pointless since this oil only had 10 miles on it, and the oil is now residing at an intersection. I'd say the engine is well and truly out of oil now.

I only hope that since the engine was only idling when it imploded, the new turbo is still in one piece. I won't know that until I can pull it out again, once I know what will be happening to the whole package.
Fuel-related causes should certainly be explored, as any other theory. I'm happy to address any questions about this, whatever the resultant knowledge. This should be a learning experience for everyone, to know what to avoid doing.
It may be that the purpose of my experience is to serve as a warning to others.
