## Discrepancy

(CAN) THE SUBMITTER REPORTS AN INCREASE IN OIL LEAKS, IN CRANKSHAFT OUTPUT SEALS, IN RECENTLY OVERHAULED ENGINES.  IN A PREVIOUS CASE, THE SEAL WAS FOUND LEAKING AND IN THIS CASE, THE SEAL WAS FOUND UNSEATED (HANGING LOOSE ON THE OUTPUT SHAFT).  IN BOTH CASES, THE SEALS WERE LACKING THE SEALANT THAT SHOULD BE USED DURING INSTALLATION.
