## Discrepancy

UPON REMOVAL OF CYLINDER NR 1, INSPECTION OF LIFTERS OF CAM LOBES REVEALED CYLINDER LIFTER FACE CHIPPED OUT CAUSING SCRATCHES ON CAMSHAFT LOBE.  THIS AIRCRAFT DOES NOT HAVE A HISTORY OF PROLONGED PERIODS WITHOUT FLYING.  ENGINE INSTALLED LESS THAN 3 YEARS AGO.  THIS WAS A FACTORY RE-BUILT ENGINE.  SUBMITTER STATED IF OPERATION HAD CONTINUED, SEVERE SPALLING WITH LIFTER AND LOBE WOULD HAVE DEVELOPED.
