But you can't have the oil thing both ways, one minute you are saying that the oil would stop the engine dead and now you are talking about it NOT stopping it at all, in fact the opposite.
But that was my point, the quantity of oil from a broken turbo is not huge (the oil pipe is quite narrow I believe) so it would probably burn it.
To get enough into the cylinder to cause a fluid lock the intercooler would have to be full and a blown turbo is not going to run on long, the drop off in power and the noise means that the engine is normally stopped quite quickly.
It depends on the rate at which the oil reaches the head - I was just trying to demonstrate that oil does reach the head from the turbo EVEN under normal circumstances. If there's sufficient oil to stop the engine, it will, otherwise it will burn. The quantity of oil lost from a turbo can be large because if the engine is running, it's still at full pressure and the seals will have failed - the turbo only has to stop for the seals to fail! It's not just down to the size of the oil supply pipe - that's to control the flow. Look at the size of the oil return pipe! My Lupo lost 1L of oil in no time at all. It took some miles to burn off all the oil from the exhaust after everything was repaired. The inlet side was cleaned with a pressure washer. I couldn't do that with the exhaust!
