## Discrepancy

(CAN) THE FLIGHT CREW REPORTED A MINOR ENGINE VIBRATION AND HIGH NR 2 CYLINDER EGT AS WELL AS ERRATIC CHT INDICATIONS.  EXAMINATION FOUND THAT DUE TO FAULTY INFORMATION FROM THE MULTI PROBE SYSTEM THE OBSERVED INFORMATION ACTUALLY REFLECTED NR 6 CYLINDER OPERATION.   NR 6 CYLINDER WAS REMOVED AND THE EXHAUST VALVE WAS FOUND BROKEN IN THE SEAT AREA. THE ASSEMBLY WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
