## Discrepancy

UPON REMOVAL OF NR 3 CYLINDER DUE TO LOW COMPRESSION.  THE EXHAUST LIFTER AND CAMSHAFT WERE FOUND SEVERELY SPALLED.  THE INTAKE LIFTER HAD MINOR SPALLING.  THE LUBRICATION SYSTEM WAS FOUND TO BE CONTAMINATED WITH METAL.  BOTH LIFTER HAD CORROSION ON THE SIDEWALKS, CAUSING THE UNITS TO STICK IN THE CRANKCASE.
