## Discrepancy

AN UNACCEPTABLE OIL SAMPLE LEAD TO A RECOMMENDATION BY AN OUTSIDE COMPANY TO HAVE AN INSPECTION OF THE CAMSHAFT AND LIFTERS PERFORMED. WE PERFORMED THESE INSPECTIONS AND FOUND A GOUGE ON THE #6 INTAKE LOBE ON THE CAMSHAFT. A PICK CAN BE CAUGHT IN THIS GOUGE THEREFORE IT IS REASON FOR REJECTION. THE LIFTER WAS IN GOOD CONDITION. THE #6 EXHAUST LIFTER SHOWED SIGNS OF HEAT/DISCOLORATION.
