## Discrepancy

(CAN) DURING INSPECTION #6 CYLINDER WAS FOUND TO HAVE ZERO COMPRESSION. ON REMOVAL OF THE CYLINDER IT WAS FOUND THAT THE EXHAUST VALVE SEAT HAD LIFTED AND WAS COCKED AT AN ANGLE HOLDING THE EXHAUST VALVE OPEN. THIS RESULTED IN LACK OF COMPRESSION AND CAUSED ADDITIONAL DAMAGE TO THE ENGINE.
