## Discrepancy

ON CLIMB-OUT AFTER TAKEOFF, RT ENGINE OIL TEMPERATURE BEGAN TO RISE AND PRESSURE BEGAN TO FALL.  PILOT IMMEDIATELY SHUT DOWN RT ENGINE AND RETURNED TO AIRPORT WHERE AN UNEVENTFUL LANDING WAS MADE.  LOSS OF ENGINE OIL WAS DISCOVERED TO BE COMING FROM THE NR 4 BEARING HOUSING AREA.  THE COTTER PINS HOLDING THE PIN FOR THE EMERGENCY FUEL SHUT-OFF LEVER ON THE NR 4 BEARING HOUSING HAD FAILED (WORN) ALLOWING THE LEVER PIN, LEVER, AND ACTUATOR ROD TO FALL OUT, WHICH ALLOWED OIL TO ESCAPE THROUGH THE ACTUATOR ROD HOLE.
