## Discrepancy

(CAN) RECEIVED ENGINE, AFTER A REPAIR FOR PREMATURE CAMSHAFT FAILURE (REF: SDR 20070319008).  AFTER INSTALLATION AND RUN-UPS, AN OIL LEAK WAS DISCOVERED AT THE CRANKSHAFT SEAL. WHEN THE SEAL WAS REMOVED IT WAS NOTED THAT IT WAS A (SPLIT) TYPE SEAL NOT THE ONE-PIECE AS CALLED FOR IN THE IPC.  AFTER SPEAKING WITH REPAIR STATION, THEY AGREED TO COVER THE LABOR AND NEW SEAL COSTS. A NEW SEAL WAS INSTALLED AND THERE HAVE BEEN NO LEAKS SINCE. WE RETURNED THE DEFECTIVE SEAL, AS THEY REQUESTED IT FOR QUALITY PURPOSES. (TC NR 20070503006)
