* A S195 diesel engine, replacement of the new valve, valve guide and valve seat, and the valve seat and valve were carefully reaming and grinding, installed after the start, the valve top piston occurs the phenomenon.

Remove the exhaust valve and found the intake valve than the exhaust valve 3 mm long, after replacing the standard new valve. Troubleshooting. * A new S195 diesel engine took just over three months to burn 17 kilograms of oil. During this period, the crew replaced three sets of piston rings, a cylinder liner, intake and exhaust valves and ducts, but the fault still persists. Remove the connecting rod check no bend
