## Discrepancy

CLEANED UP ALL VISIBLE OIL , CHECKED DUCTS NO OIL FOUND.  APU PUT ON MEL AND NEXT TAKEOFF ABORTED DUE TO SMOKE IN CABIN.  ACFT CAME BACK TO GATE, DUCTING CHECKED AGAIN NO OIL FOUND IN PACK DUCTING, APU WAS ALREADY ISOLATED BUT OIL WAS FOUND FORWARD OF THE ISOLATION VALVE IN BLEED DUCT FROM ORIGINAL LEAK.
