## Discrepancy

(CAN) CUSTOMER COMPLAINED OF RED OIL IN HIS ENGINE OIL. THE PROPELLER WAS SENT IN OFR REPAIR, AND IT WAS DETERMINED THAT THE CYLINDER WAS BADLY WORN INTERNALLY AND THAT THE SEAL WAS ALSO BADLY WORN.  THIS ALLOWED RED OIL FROM INSIDE THE HUB TO ENTER THE OIL SYSTEM.   A NEW SEAL AND CYLINDER WERE INSTALLED, THE PROPELLER WAS ASSEMBLED, AND LOCKED.
