This was the interior of a Jeep engine that was in a Jeep that was inadvertently towed quite some distance in first gear, low range. This is only a guess, but I can imagine someone maneuvering the Jeep up behind the towing vehicle going as slow as possible while someone else hitched the two together and then just turned the engine off, leaving it in gear, and away they went. It was estimated that the engine could have reached 50,000 RPM. Did about $30,000 worth of damage. That would be close to the price (after discounting) of a new base Wrangler. I would just keep this one for parts and buy a new one. I know, it was stupid, but stupid things happen. ???
