Before we pulled the engine, we checked all the possible causes that could be checked with it in the truck. No coolant in the cylinder, no coolant in the oil, no evidence of fuel in the cylinder, no bent push rods or loose rockers. When discussing it with others, we concluded that #6 injector hung open in one of the 4-stroke cycles and bent the rod. The engine ran only for about 20 seconds before we shut it down for the leak. Watching the video, we notice a couple of knocks in the last second, which leads me to believe that when we shut it down the loss of power from the other cylinders allowed to piston/rod to bind up at the bottom of the cylinder at the bottom of the stroke as it stopped.
