## Discrepancy

UPON VISUAL INSPECTION OF THE EXHAUST SYS, DURING THE ANNUAL INSP, IT WAS FOUND THE THE UPPER V-BAND CLAMP LOCATED ON THE TURBOCHARGER WASTEGATE HAD CRACKED AND WAS SEPARATING.  UPON REMOVAL OF THE CLAMP IT WAS FOUND THAT THE GASKET (PN 75845) HAD BLOWN OUT AND WAS BLOWING HOT EXHAUST ONTO THE REAR PORTION OF THE V-BAND CLAMP CAUSING IT TO CRACK AND SEPARATE.
