## Discrepancy

CYLINDER REMOVED FROM ENGINE DUE TO ALUMINUM IN OIL SCREEN.  FOUND PIN PLUG SHAVED COMPLETELY OFF ON NR 3 CYLINDER ALLOWING PIN TO RUB AGAINST CYLINDER WALL.  THESE TYPES OF PIN PLUGS ARE A LOOSE FIT UNLIKE SUPERIOR AIR PARTS, INC., STYLE AND WERE INSTALLED WITH CORRECT LYCOMING PART NUMBER AND FIT.  REMAINING PIN PLUGS SHAVED ALSO.
