## Discrepancy

THE PUSH ROD HOUSING TUBE RETAINING SPRINGS WERE BROKEN AT THE BEND JUST OB OF THE MOUNT HOLE.  THE UNBROKEN SPRINGS HAD A TOOL LINE AT THE POINT OF THE BEND.  THERE WERE 2 BROKEN SPRINGS, LOCATED ON NR 3 AND NR 4 CYLINDERS.  ONE SPRING HAD ONE SIDE BROKEN OFF THE OTHER BOTH SIDES WERE BROKEN.  BELIEVE THE TOOL MARKS ARE CAUSING THE PROBLEM.  ALL 6 SPRINGS WERE REPLACED WITH NEW MFG PARTS AND SOME ALSO CONTAINED THE TOOL MARKS AT THE BEND.  (K)
