## Discrepancy

OIL PRESSURE SWITCH USED TO TURN ON FLIGHT TIME RECORDER ('HOBBS" METER) BEGAN TO LEAK OIL FROM ONE ELECTRICAL TERMINAL.  A FEW DROPS OF OIL WERE NOTICED WHILE PRE-FLIGHTING FOR A 2-1/2 HOUR RETURN FLIGHT.  AFTER RETURNING, THERE WAS A LARGE OIL LEAK.  ENGINE WAS 3 QUARTS LOW.  TESTING SWITCH INDICATES LARGE OIL LEAK AT ELECTRIC TERMINAL.
