## Discrepancy

AFTER REMOVAL OF THE CYLINDER, FOUND THAT THE CRANKSHAFT MAIN BEARINGS FROM THE NR 6 CYLINDER WERE CRUSHED AND PARTS OF THEM MISSING, LATER FOUND THE REMAINING PIECES OF BEARING MATERIAL AND PIECES OF THE CONNECTING ROD END CAP, NUTS AND BOLTS IN THE OIL SUMP. THE CRANK LOB WAS FOUND DISCOLORED AND DAMAGED FROM POSSIBLE OIL STARVATION AND HEAT.
