## Discrepancy

ON ANNUAL INSPECTION, ROCKER COVERS REMOVED FOR GASKET LEAKS.  FOUND PUSH ROD RETAINERS ON NR 1 AND NR 2 CYLINDERS BROKEN.  THESE WERE SUPERIOR MILLENIUM CYLINDERS WITH 346 HRS SINCE NEW.  SUBMITTER STATED PROBLEM IS BELIEVED TO BE INSUFFICIENT SURFACE AREA FOR THE RETAINER TO SEAT AGAINST.
