## Discrepancy

DURING CLIMB THERE WAS A PACK ODOR, PACKS FULL COLD.  FLIGHT ATTENDANTS REPORTED SMOKE DETECTORS IN LAVATORY SOUNDING.  FLIGHT CREW WENT TO MANUAL ON PACKS AND SELECTED A WARMER SETTING.  SMELL AND ALARMS CEASED IN ABOUT 2-3 MINUTES.  OK REST OF FLIGHT.  MAINTENANCE FOUND APU OIL LEAK AT LOP SWITCH.  MAINTENANCE REPAIRED SAME.  APU LEAK CHECK GOOD.  APU INLET AREAS CLEANED AND PACK BURNOUT/OPN 5089 PERFORMED.  MAINTENANCE ALSO REPLACED BOTH WATER SEPARATOR BAGS.
