## Discrepancy

ON RUN-UP ONCE I GOT UP TO THE FLY POSITION AND WAS STARTING TO PULL PITCH THE MEDIC ASKED ME WHAT ALL THE SMOKE WAS.  I LOOKED TOWARD THE REAR LEFT AND WE WERE ENGULFED IN SMOKE.  I IMMEDIATELY SHUT THE ENGINE DOWN.  I APPLIED THE ROTOR BRAKE AND ONCE THE ROTORS STOPPED, WE EXITED THE AIRCRAFT.  I MADE SURE I COULD NOT SEE ANY FIRE AND THE SMOKE STARTED TO SUBSIDED.  I OPENED THE ENGINE COWLING TO INSPECT THE AREA.  FOUND OIL ALL OVER THE ENGINE DECK AND COWLING.  NOTIFIED AIR COM, AM AND MECHANIC.  A REAR BEARING CLEANING WAS RECOMMENDED SO WE WILL ACTUALLY BE CHANGING THE MO3 FOR OUR COMPLIANCE.  COKING WAS FOUND AT THE REAR BEARING OIL STRUT.
