## Discrepancy

ENGINE WAS RETURNED TO THIS REPAIR STATION FOR SMOKE AT START UP AND TAILPIPE OIL LEAK AT SHUTDOWN. UPON DISASSEMBLY NOTICED INTERNAL OIL FEED TUBE CONNECTED TO THE FEED CHAMBER OF THE HOUSING TO BE LOOSE. THE TUBE SEPERATED TO A POINT THAT THERE WAS A GAP OF  1/16" BETWEEN THE TUBE AND THE FEED CHAMBER OF THE HOUSING. THIS FEED LINE SUPPLIES OIL TO NR 2 AND 3 BEARINGS VIA AN OIL FEED RING THAT HAS THREE OIL JETS AIMED AT THOSE BEARINGS. THE BEARING DID NOT SHOW ANY EVIDENCE OF WEAR OR DAMAGE, JUST MINOR VARINSH OR COCKING, NO ROUGH ROTATION. THE HOUSING, BOTH BEARINGS AND OTHER ASSOCIATED PARTS ARE BEING SENT DESIGN HOLDER FOR FURTHER INVESTIGATION.
