## Discrepancy

WRONG SIZE ADEL CLAMP ON OIL LINE TO WASTEGATE UNDERNEATH OIL SUMP.  THE CLAMP MOVED ON ENGINE MOUNT CAUSING CONTACT BETWEEN THE METAL BAND ON OIL LINE AND THE SUMP.  CHAFING OCCURRED RESULTING IN MATERIAL LOSE OF OIL SUMP.  REPLACED CLAMP WITH PROPER SIZE, REPLACED OIL SUMP WITH NEW AND CHECKED OIL LINE FOR SECURITY.
