If you have no other clues, try PTCrew.Com - lotsa turbo gurus there...

Thanks. Shouldn't the Turbo last more than a few minutes without oil flow. I would think it would take a couple hundred miles of driving before it destructs.
It's getting oil. I removed the drain line hose at the bottom and placed the end of the line in an oil can. Started the motor. The oil is making it through the Turbo. How much oil flow does it require? Example: A steady oil flow as if you open a drain plug. A fast drip or a slow drip.

A few minutes, at the temps a turbo gets, I would think is enough to cook it.
If you're getting oil, then I don't know why it died.

Even without the oil flow, it's cooled by engine coolant. I would think that would take care of the heat issues until the bearings give out.
Thanks for the help and I'll check out PTCrew. If I get it figured out, I'll get back with feedback.

Update.
Turbo was changed without changing the exhaust manifold. The alignment pin was in a different location. This made the wastegate actuator arm bind and so the internal wastegate was not working as it should. This caused the Turbo to overspeed and cause the bearings to fail.

Thanks for posting back with the cure - I haven't heard of that problem before....
