    If your engine is hydrolocked it means any liquid (in your case, H2O) has flooded the cylinder. Air is compressible but liquids (in your case H2O) won't. If H20 is in the engine the piston cannot move in the cylinder because H2O cannot expand/compress. The connecting rods are usually the first things that may bend or break.

    Pull all of the spark plugs out and try to start it then. If it turns over crank for several seconds. put a table spoon of oil into each plug hole and crank some more to displace any water left in cylinders. If it is not turning over after pulling the plugs she very well could have snapped a rod that has locked up the motor.

    Wow. Never thought of that OFFGRID. I remember guys doing that years ago to their hot rods to determine bad cylinders. Great idea.
