For this, can oil leakage occur from rear bearing(Exhaust cone/ Dome over the pump) bottom side just front of the 4 th stage turbine rotor viewed from rear.

pjvr99 Posted May 27, 2020 Share Posted May 27, 2020 Yes, because it is flooding through the delivery nozzles and tubes as though the engine were running Quote Link to comment Share on other sites More sharing options...
