What you discovered above will lead you to understanding the solution to unsticking the engine. An engine that was in a covered shed, had no visible sign of water infiltration, and was full of oil and coolant- but stuck- is usually an easy fix. The rings, which are cast iron, are usually stuck to the cast iron cylinder walls but only in the cylinders which are open to the atmosphere. If you followed the firing order of the engine, you could determine which are open cylinders and which are closed. You can start by pulling the spark plugs out and inject [http://www.crankshaftcoalition.com/wiki/Removing_stuck_fasteners#Some_recommended_penetrating_fluids penetrating oil] with a trigger type oil can.

{{!}} Diesel fuel reeks and is truly a foul smell to have all over everything it comes into contact with. For that reason, it is not recommended unless that is all that's available. Marvel Mystery Oil, PB blaster or WD-40 are all acceptable, and kerosene works as well. DO NOT use gasoline or a solvent-like product as they do not provide any lubricity, plus are a fire hazard.

{{Note1}} Diesel fuel reeks and will leave a foul smell on everything it comes in contact with. For that reason, diesel fuel is not recommended for use unless that is all that's available. Marvel Mystery Oil, PB blaster or WD-40 are all acceptable, and kerosene or kerosene/ATF mixed together works as well. DO NOT use gasoline or other highly flammable solvents as they do not provide any lubricity, plus they are a respiratory and fire hazard.
