## Discrepancy

WHILE IN CRUISE, THE CREW REPORTED THAT THE LAVATORY SMOKE DETECTOR WENT OFF AND THAT A STRONG SMELL WAS COMING FROM PACK NR 2.  INITIALLY, THE NR 2 PACK WAS DEFERRED AND THE SMOKE DETECTOR WAS OPERATIONALLY CHECK GOOD.  THE DEFERRAL WAS CORRECTED WHEN MAINTENANCE REMOVED AND REPLACED THE NR 2 ENGINE FOR LEAKING OIL INTERNALLY WHICH WAS CAUSING THE SMELL AND POSSIBLY THE SMOKE.
