## Discrepancy

DURING INSPECTION, SAW NR 3 CYLINDER WITH ALL OF THE HOLDDOWN STUDS BROKEN OFF.  THE CYLINDER MOVED IN AND OUT AND BROKE CONNECTION ROD, PUSH ROD TUBES, FUEL INJECTOR LINE, EXHAUST RISES, INDUCTION TUBES.  1 OF THE BROKEN STUDS HAVE A FILM OF RUST ON IT.  THIS COULD BE THAT THE 1 STUD WAS BROKEN FOR A BIT OF TIME.  THE BROKEN FUEL LINE AND THE OIL DID CREATE A SMALL ENGINE FIRE.  BURNED SOME WIRING INSULATION.  ENGINE WAS REMOVED FOR O/H.  ALL 6 CYLINDER WERE INSTALLED 1/14/1999 AT ENGINE TIME 886.1.  THE CYLINDERS ARE PN 05K21118.
