## Discrepancy

DIVERTED TO SLC DUE TO AN APU OIL LEAK.  NR 1 GENERATOR WAS PREVIOUSLY DEFERRED.  UPON OPENING APU COWLING FOUND A LARGE AMOUNT OF OIL INSIDE.  *S/D*  FOUND OIL LEAKING THRU STARTER MOTOR.  REPLACED STARTER MOTOR WITH UPGRADED DASH 7.  ALSO, REPLACED GEARBOX SHUTOFF VALVE AS A PRECAUTION FOR HIGH OIL CONSUMPTION.  AFTER STARTER REPLACEMENT, APU LEAK CHECK AND OPERATIONAL WERE GOOD.
