## Discrepancy

DURING 100 HOUR INSP OF A/C, DISCOVERED NR 1 CYL COMPRESSION WAS READING 25/80 AND OIL FILTER CONTAINED AN EXCESS AMOUNT OF ALUMINUM SHAVINGS.  NR 1 CYL WAS REMOVED FROM SERVICE TO INVESTIGATE REASON FOR LOW COMPRESSION AND EXCESS ALUMINUM IN THE FILTER.  NR 1 CYL EXHAUST VALVE, GUIDE AND SEAT WERE ALL WORN BEYOND LIMITS.  PISTON PIN PLUGS SHOWED SIGNS OF WEAR AND SCUFFING ON CYL WALLS.  BOREASCOPE INSP OF OTHER 3 CYL  SHOWED SIGNS OF SIMILAR SCUFFING.
