## Discrepancy

INFLIGHT ENGINE SHUTDOWN,  DUE TO A HIGH OIL PRESSURE INDICATION.  PERFORMED A VISUAL INSPECTION OF RT ENGINE WITH NO ISSUES.  PERFORMED A GROUND RUN TO CONFIRM HIGH OIL PRESSURE & DID NOT FIND OIL PRESSURE HIGH,  FOUND OIL PRESSURE LOW, SHOWING 34 PSI AT IDLE & 39 PSI AT TAKEOFF POWER.  INSTALLED A DIRECT READING GAUGE & PERFORMED A GROUND RUN & CONFIRMED BOTH AIRFRAME & ENGINE OIL PRESSURE WERE READING THE SAME.  SWAPPED BREATHER VALVES FROM LT TO RT & ADJUSTING PRESSURE TO 35 PSI AT IDLE, 40 PSI AT 88% N2 & 42 PSI AT TAKEOFF POWER.  LT & RT ENGINE BREATHER VALVES WERE FOUND IN SERVICEABLE CONDITION.  ALL GROUND RUNS FOR LEAK CHECK WERE PERFORMED WITH SATISFACTORY RESULTS.  OIL PRESSURE WITHIN LIMITS.
