If they over filled the engine with oil like they said they did, they would have hydro locked the engine. Remember back in high school physics (are kids still require to take H.S. Physics?) that liquid can not be compressed, so if enough oil got into the cylinders and the valves are closed the oil has no where to go and you can't compress a liquid so something has to give.

They could have removed the spark plugs and drain the oil from the cylinders and sump. And if they were lucky they might had dodge a bullet and the engine will still run.
