RE: seized motor and some Q
Is it a gas engine? Or a diesel? pull the plugs and inspect. If you have a cylinder full of water, you won't get it to turn. Also, if the coolent was allowed to sit in the cylinder for a year, you should pull the heads and hone the cylinder. If there is nothing in the cylinders after you remove the plugs, (or injectors on a diesel) try pouring a good amount of a light machining oil or my favorite, Marvel Mistery Oil in the cylinder and let it sit a good long while (week or more, depends on how long you can wait, or how long it takes I like to try it every other day or so). Then try to get it to move. Once you get it to start moving, siphon the oil out or just let it flow out the open injector/plug hole if you don't mind the mess.
When baring an engine, most people do try to turn it in the direction it normally turns, but it usually won't damage the engine to bar it the other way a little. Rocking it back and forth will help break it free. I've seen some pretty old engines that have been siezed for years broken loose this way and running within an hour.
The pulley at the bottem front of the engine, the one attached to the crankshaft, is the correct bolt/place to turn it over.
Good luck!
