You do realize that oil cavitation due to a rapid drop in pressure is the same thing. It's not flashing in a sense of reaching ignition, but is boiling / cavitating from a rapid change in pressure. That's what causes cavitation...a rapid pressure drop.I highly doubt there is any oil "flashing" or "boiling/vaporization" going on as the oil comes out of the bearing since going through the bearing would have to raise the oil temperature from ~200F to over 450F. If you study up on journal bearings the normal oil temperature rise as it gets squeezed and sheared by going through the bearing is around 30~40F ... not a rise of 250+F. (200F to 450+F).
In order for the bearing to raise the oil temperature inside the bearing to 450+F, the clearance would have to be very very small, and besides if oil the localized oil temperature is raised to 450+F the MOFT will go to zero and the bearing will literally smoke itself with metal-to-metal contact. That's why I don't believe that theory.
