## Discrepancy

(CAN) THE ENGINE WAS REMOVED DUE TO METAL CONTAMINATION IN THE OIL.  DURING DISASSEMBLY OF THE ENGINE, PREMATURE WEAR WAS NOTICED OF THE LIFTER BODY FACE AND OF THE INTAKE AND EXHAUST VALVES OF NR 1 CYLINDER; OF THE INTAKE VALVE OF NR 3 CYLINDER IN THE FORM OF SPALLING AND GALLING AND OF THE AFFECTED CAMSHAFT LOBES. THE FOUR PISTONS HAD SCRATCHES AND MANY METAL PARTICLES IMPREGNATED IN THE PISTON FACE.  ALL DEFECTIVE PARTS WERE REPLACED AND THE ENGINE WAS REPAIRED.
