## Discrepancy

(CAN) CYLINDER WAS REMOVED DUE TO LOW COMPRESSION AND INCREASE IN OIL CONSUMPTION. INSPECTION FOUND THE HEADS OF THE PISTON PINS MUSHROOMED OVER. FURTHER INSPECTION REVEALED THE ALUMINUM PLUG BROKEN IN HALF. NO DAMAGE WAS FOUND ON THE STEEL PIN. INSPECTION OF THE OTHER PISTON PINS FOUND NO FAULT. ENGINE WAS REASSEMBLED.
