## Discrepancy

'ACCESSORY CASE OIL LEAK'.  A FACTORY LYCOMING ENGINE HAD A PERSISTENT SLIGHT OIL SEEP AT THE MAGNETO BASE.  AFTER REMOVAL, IT WAS FOUND TO HAVE A FLAW IN THE APPARENT CASTING.  A LOW SPOT IN THE GASKET AREA ALLOWED OIL TO SEEP BY.  PART WAS REPLACED FOR THIS REASON AS WELL AS FLANGE/CLAMP WEAR.
