## Discrepancy

NEWLY OVERHAULED COMBUSTOR HOUSING INSTALLED ON ENGINE LE-45876, DURING REPAIR.  WHILE ASSEMBLING THE ENGINE, A HIGH AND UNACCEPTABLE DELTA (P) WAS CONFIRMED, WHICH INDICATED CLOGGED OIL PASSAGE AT THE NR 2 AND NR 3 BEARING BORE AREA.  FURTHER INVESTIGATION CONFIRMED THE PROBLEM.  REPAIR WORK AT VENDOR HAS BEEN HALTED PENDING FURTHER REVIEW AND SUCCESSFUL PROCESS AUDITS.  NOTE: NO NONCONFORMING PARTS HAVE BEEN RELEASED TO SERVICE BY THIS FACILITY.
