Narrative:
According to the pilot's statement, the converted Ford V6 automotive engine overheated and seized when a malfunctioning thermostat valve allowed excess pressure to build up inside the coolant system. The resulting overpressure blew out a plug in a coolant outlet from the block, which is unused in this installation. The coolant was then pumped overboard and the engine seized. The aircraft collided with fence posts during a forced landing onto a road.

Probable Cause: a loss of engine power due to a malfunctioning thermostat valve in the liquid cooling system.
