## Discrepancy

PILOT REPORTED THAT, AFTER LANDING, HE OBSERVED ENGINE OIL LEAKING FROM THE NR 2 ENGINE.  THE OIL LEVEL WAS VERIFIED TO BE JUST INDICATIONS OF OIL PRESSURE LOSS, FLUCTUATION OR HIGH TEMP. MAINTENANCE REPLACED THE OIL COOLER AND LATER VERIFIED THAT IT WAS CRACKED (BENCH CHECK VERIFIED LEAK AT A CRACKED ENDI PLATE WELD). (K)
