## Discrepancy

ACCESSORY CASE WAS PARTIALLY DISASSEMBLED FOR CLEANING DURING MAJOR ENGINE REPAIRS.  OIL PRESSURE RELIEF VALVE SPRING WAS WORN ON OUTSIDE OF COILS WHERE THEY RIDE ON INSIDE OF RELIEF VALVE PLUNGER.  COILS WERE WORN TO .034 INCH FROM .050 INCH NEW DIAMETER.  THIS SPRING IS TO BE REPLACED AT EACH OVERHAUL.
