## Discrepancy

(CAN) CRACKED COMPLETELY THROUGH FROM ONE SPARK PLUG HOLE TO THE EXHAUST VALVE SEAT TOTHE OTHER SPARK PLUG HOLE. CYLINDER WAS REPAIRED 25.6 HOURS PREVIOUS. (DUE TO EXHAUST VALVE PROBLEMS) NOTE: LOGBOOK INCORRECTLY STATED CYLINDER WAS OVERHAULED. CYLINDER WAS ACTUALLY REPAIRED 25.6 HOURS PREVIOUS.  CYLINDER FAILURE OF THIS TYPE IS NOT UNCOMMON ON LARGER 6 CYLINDER ENGINES.
