The problem is most likely moisture causing rusting in one or more cylinders. It is best to determine the reason for the engine being stuck. So removing the heads and possibly the pan are the the best way to begin the process. Because it takes much more labor many try to loosen the parts by putting a penetrating lubricant into each cylinder. Automatic Transmission Fluid or Marvel Mystery Oil or PB Blaster are what I have found to work the best. Take out the spark plugs and squirt the oil in each cylinder. Let it soak for a few days. Then try to move the flex plate both clockwise and counterclockwise. I use a large screw driver to put mild pressure on the teeth of the flex plate. If it does not move then stop! You might try adding more oil and soaking a few more days or take the heads off to inspect the cylinders.

Not necessary to remove the gas. It will evaporate or migrate into the crankcase. As long as it is not too much it won't have much effect on the oil.

Well the motor is turning pretty freely so i am safe there for now but i found why shes not starting for at least one reason. NO SPARK :( There was nothing even at the distributer which is an efi and fairly new. I am noticing wires to my lights are completely rotted and fell apart so i am hoping to find some bad wires leading to the distributer. Is this a good possibility or am i looking at a costly replacement of the distributer i have in there now?
