'Interference' engines have been around for a very long time, but combining this trait with a drive mechanism with a strictly limited, but slightly unpredicatble life is where the problems arose. A better anology would be an interference engine where e.g. the valves are controlled directly by a micro rather than a camshaft. Micro hangs, engine grenades itself.
