The defect
FOUR COMPRESSION BACKPLATE RETAINING FASTENERS ON THE TURBO-CHARGER WERE TORQUED ONLY HAND TIGHT. THIS ALLOWS THE FASTENERS TO LOOSEN, AND CAUSES OIL TO LEAK INTO THE COMPRESSOR AIR SIDE OF THE TURBO-CHARGER WHICH, WHEN COUPLED WITH THE HEAT PRECIPITATED BY THE COMPRESSOR AND THE MIXING ACTION OF THE COMPRESSOR WHEEL, CAN RESULT IN AN AIR/OIL MIXTURE THAT FUELS THE ENGINE.
The risk
WHEN THIS OCCURS, ENGINE RUN-ON AND SUBSEQUENT LOSS OF OPERATOR CONTROL VIA THE NORMAL THROTTLE MECHANISM CAN OCCUR, WHICH COULD RESULT IN A VEHICLE ACCIDENT.
The remedy
REPLACE THE SUSPECT TURBO-CHARGER WITH A NEW TURBO-CHARGER.
