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 stuck to the cast 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 penetration 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 is good 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. | What you discovered above will lead you to understanding the solution to unsticking the engine.
