Removing water from spark plugs

You would have to have driven through an incredible deep puddle in order to get a waterlogged engine. I do hope that it stalled and that you have not tried to start your engine since then. Because when water gets sucked into the engine and the engine tries to compress it with the pistons, and since water just cannot be compressed, something usually has to give and it is easily possible to bend the piston rods. You did not tell us how long ago that this has happened. Unhook the battery before anything else. You so not want to accidentally start the engine while somebody is working on it. Remove the spark plugs, and turn the engine over by hand for a few full rotations. You can use a shopvac to remove as much of the water coming out of the cylinders. Once they are reasonably empty, use a handoiler and squirt regular engine oil into the cylinder via the sparkplug hole. Continue to turn the engine over by hand. It is very seldom that the piston rings seize to the cylinder wall. Once you are reasonably sure that the water is gone, replace the plugs, clean your air intake system of all water. Change your engine and transmission oil. Then reevaluate for any damage. Just out of curiosity, tell us more about this "puddle"
