## Discrepancy

DURING T/O ROLL PILOT NOTICED FUNNY ODOR IN CABIN SIMILAR TO OIL ODOR.  A FEW SECONDS INTO CLIMBOUT, LAV SMOKE DETECTOR SOUNDED.  A/C RETURNED TO FIELD AT PHL AND LANDED WITHOUT INCIDENT.  MX INSPECTED A/C, PERFORMED GROUND RUNS AT ALL POWER SETTINGS WITH BLEEDS & PACKS ON.  NO INDICATIONS OF SMOKE OR LAV SMOKE INDICATION.  REMOVED AND REPLACED LAV SMOKE DETECTOR.  A/C FERRIED TO IND FOR FURTHER EVALUATION.  A THOROUGH INVESTIGATION AND CHECKS WERE PERFORMED ON THE A/C AND ENGINES, AND NR 1 ENGINE WAS CONFIRMED TO BE CAUSING THE ODORS.  NR 1 ENGINE WAS REMOVED AND REPLACED PER TASK CARD CE720001.  ENGINE RUNS ACCOMPLISHED, NO LEAKS AND NO ODORS NOTED IN CABIN.  AIRCRAFT RETURNED TO SERVICE.
