While pulling away from a stop light in light city traffic, engine suddenly had reduced power output immediately followed by loud sounds of loose metal parts through out the engine compartment. Upon inspection by a Porsche specialist, he determined that the engine had suffered intermediate shaft failure which caused catastrophic engine failure by allowing the valves to make contact with the piston heads and shredding ball bears which sent metal shaving through the oiling system. The engine is considered non-repairable and requires a complete replacement engine.
