## Discrepancy

DIVERSION TO LAS DUE TO LOSS OF THE LEFT ENGINE OIL QUANTITY AND OIL PRESSURE.  AN EMERGENCY WAS DECLARED INTO LAS, ENGINE WAS NOT SHUT DOWN, CREW KEPT ENGINE RUNNING AT POWER AND THAT THE OIL PRESSURE DID NOT GO BELOW 14PSI.  CORRECTIVE ACTION: FOUND OIL LEAKING FROM OIL CLOGGING TRANSMITTER, REPLACED O-RINGS LEAK CHECKS GOOD.  FOQA DATA SHOWS ENGINE RAN BELOW 13PSI BEYOND AMM LIMITS, ENGINE CHANGE REQUIRED.
