## Discrepancy

(CAN) DURING 300 HOUR SB388C VALVE GUIDE INSPECTION IT WAS NOTED BY THE ENGINEER THAT ONE OF THE PUSH RODS HAD BEEN BENT DURING OPERATION. AFTER FURTHER INVESTIGATION IT WAS DETERMINED TO HAVE HAD THE INCORRECT LENGTH PUSH ROD INSTALLED AT ENGINE OVERHAUL. PROPER PUSH ROD LENGTH INSTALLED AND NO FURTHER ISSUES ENCOUNTERED.
