I had a motor that water got into somehow. I pulled the plugs and cranked the engine over. When no more came out, put the plugs in and tried to fire it. You want to be careful if there still is some water in there, when the cylinder fires, it will create steam and crack the block. (Ask me how I know that
) Might want to check the oil BEFORE you start it, and if its high on the stick or looks like chocolate milk, don't drink it, drain it. After you change start it, then change it again to get any water that might be left. Definitely check the trans and rear. Gas tank too. Sorry to hear bout that.
