## Discrepancy

PILOT REPORTED LOSS OF OIL PRESSURE DURING FLIGHT.  THE ENGINE WAS SHUT DOWN AND AN UNEVENTFUL LANDING MADE.  OIL WAS LEAKING FROM THE COMPRESSOR INLET AND BLEED AIR VALVES.  AFTER TROUBLESHOOTING, THE ACCESSORY GEARBOX WAS DISASSEMBLED AND THE INLET SCREEN FOR THE OIL SCAVAGE PUMP WAS BLOCKED WITH VARNISH COATING FROM INSIDE THE GEARBOX.  ENGINE REMOVED AND SENT TO P AND W FOR REPAIR.
