    Can anyone answer the following ... does the oil pump have a failure mode such that if the inlet oil to the pump runs out / line fails and there's no tank oil , it stops the scavenge pump sending the oil out of the engine to the tank , and rather cycles the oil internally ? Just looking at the schematic and not having disassembled a pump - it appears there is a gallery joining the scavenge side to the pressure side with a spring / valve arrangement - separate to the pressure regulator ? It seems that if the input pressure drops , due to say no oil in the input line , the scavenge side redirects oil to the pressure side creating a closed loop to prevent engine seizure - as it uses what's in the sump etc ... is this correct or am I deluding myself that an engineer might have actually designed a failsafe this way ? Thanks , matt Read this topic online here: http://forums.matronics.com/viewtopic.php?p=472496#472496
