Uh-oh better hope you didn't bend a rod. Water doesn't compress like air does. The water 'hydrolocked' the engine, basically filled a cylinder and with the valves closed the piston can't compress so just stops dead.

If there is no damage, all you have to do is pull the glow plugs and turn it over. The water will spray out of the glow plug holes. Reassemble, cross your fingers, and see if it fires.

If the engine was turning when it hydrolocked, good probability that you bent a rod. The momemtum of crankshaft and bottom end components mass want to keep turning and the piston won't go up further. Something has to give and the rod bends.

Do just as tec suggested, remove the GPs and turin it over. That will give the water a place to go.

water in oil will make it turn milky dark brown color, at least on gassers. Since the diesel oil is so black it may be milky black color.

What a ****-poor design. Only lasted half a million miles.

I have a spare 7.3 I'd sell. Has some miles on it, but still ran. $400.

I just don't seem to thank its nothing major because it will start right up no noise or nothing. Does not even smoke. Just seems like its cutting out but not to bad just like a little mis or something. Pull the valve cover off. Took the push rods out and check them on a piece of glass and they all seem to be straight. What can I do now
Thanks in advanced
