## Discrepancy

THE PILOT REPORTED LOW EGT ON THE LEFT ENGINE.  A VISUAL INSPECTION OF NR 6 CYLINDER WHERE THE EGT PROBE IS LOCATED REVEALED A CRACK AT THE LOWER SPARK PLUG HOLE.  AFTER REMOVING THE CYLINDER, FOUND THE CRACK WENT FROM SPARK PLUG HOLE TO SPARK PLUG HOLE WITH MISSING METAL AROUND THE EXHAUST VALVE.
