Freeing a stuck engine

With the spark plugs out of the engine and a FULLY charged battery give the starter a one second click and then stop. Observe as you do this if the fan or crank pulley has moved slightly and which way it moved, if the valves have moved, if the starter is fully engaging into the flywheel. Take the breaker bar and turn the crank pulley back a nudge and then his the starter button again to put some torque on the flywheel. This torque multiplication will move the crank journal a degree or two and will push or pull on the piston which in turn will apply thrust against the rings. All you have to do for the moment is crack the rings loose a thousandth of an inch to allow the diesel fuel to get in to that cavity. After allowing the diesel to settle in for a few minutes use the breaker bar to remove the tension on the ring. The diesel fuel between the ring and the wall will act as a fulcrum and break the ring free from the cylinder wall. It may take a dozen or so tries before all of the stuck rings and bearing are free but with each successive try more fluid will fill the voids until the engine is free to turn. Allow the engine to make two or three revolutions before stopping the exercise. This will allow the excess diesel fuel to evacuate itself from the combustion chambers and for some of the oil in the crankcase to move in the system. The engine will now have a new place to rest while the lubrication seeps into the surfaces of the internals.
