## Discrepancy

RETURNED TO GATE AFTER 90 KNOT ABORTED TAKEOFF DUE TO OIL PRESSURE INDICATION.  ENG 2 OIL PRESSURE WENT TO ZERO.  REPLACED NR 2 OIL PRESSURE INDICATOR, OIL TEMPERATURE INDICATOR AND OIL PRESSURE TRANSMITTER.  RAN ENGINE AND OPS CHECKED OK.  THEN ON DEC 15, OIL PRESS INDICATION WAS INOP AGAIN AND THE OIL PRESSURE TRANSMITTER WAS REPLACED ONCE MORE. WIRING WAS CHECKED AND NO PROBLEMS WERE FOUND.
