An off-airport emergency landing followed loss of engine power over mountainous terrain. The pilot reported that the engine of the amateur built aircraft lost power while in cruise flight, and, although there was oil pressure, eventually seized before the landing. During the landing in a forest clear cut area, the landing gear impacted a tree trunk and the aircraft nosed over. Post accident disassembly of the engine revealed that the crankshaft separated at the crankshaft cheek between the number 3 and 4 throws. The owner reported he assembled the (experimental) engine himself using Lycoming parts, and that the engine had accumulated 631 flight hours since assembly. The owner was not a certificated powerplant mechanic.
Probable Cause: The total loss of engine power due to fracture and separation of the engine crankshaft.
