He reported that as he was making a forced landing, the acft came in contact with a washed out ditch, cartwheeled & hit a fence. An exam of the eng revealed that the #4 exhaust valve stem had failed. The #4 piston was disintegrated & pieces were scattered thru-out the inside of the eng, but the valve head was not found. The eng had accumulated 555 hrs since the last major overhaul.
