possibly siezed engine

[CSM_Bronco]

so here i was testing the depth of some small water hole...no big deal...went slow, wasn't higher than the tire even (31")...well...the bottom of it was nice and sturdy ground...very solid...no rocks...nice and smooth...

now to my problem.

i was being stupid and hit it with some more speed...to try to get some good footage...anyways, the hole was about 30' long...not that deep...i got about 3/4 of the way through it when the engine died...at this point the engine was even out of the water...well, i pushed my newly installed/rigged push button ignition and all i got was the starter engaging, and then stopping...engine wouldn't turn...got the starter checked...its just fine...i think i siezed the engine or something...

there is a good possibility i got some mud water in the TB...the engine was running cool and strong before hand...ran like a beast...i tried turning it over manually (crankshaft) and i got nothing...i'm going to try to pull the plugs tomorrow and see if it turns over...hope for the best...

if that does not work i've been told to spray some WD40 down each cylinder...an hour or so later follow it up with some oil...and then just let it sit for a day or two...

i heard it could possibly be a wedged cylinder...i tried turning the crankshaft both ways...and was told if it was wedged...it would unwedge itself turning it in the opposite direction...but like i said...i hit nothing hard...the bottom was smooth with no sudden changes...

any opinions would be greatly appreciated

Hydro lock could be the worst of the problem.

This could blow the head gasket(s), bend valves/rods, etc.

btw, a pal had same problem last month while surf fishing @ shore.. he got into a puddle; thought it was hydo-lock; but turned out his A/C compressor seized; he had A/C on @ the time. But....

Pull a few plugs to check for fouling/ any heavy whitish to brown deposits & read following from wiki and it's external xource.

Good luck to you. hope nothing is damaged severely!

"Regardless of the cause, treatment is the same. Removal of the spark plugs will allow access to the combustion chamber. By inserting an irrigation syringe fitted with a flexible plastic tube on the end, you can **** out the liquid that infiltrated the combustion chamber. Once all the fluid is removed, the chamber should be sprayed with a liberal coating of a water displacing lubricant such as WD40[citation needed], and allowed to sit until the remaining water has evaporated. Once the water or coolant has been removed, inspect the combustion chamber for rust. The best option would be to remove the head, but a borescope or small flashlight and mirror will also work. Light surface rust will be normal, but if you see any heavy corrosion, it should be gently removed, and vacuumed out of the chamber. After inspection, pour a tablespoon of assembly **** (such as Marvel Mystery Oil) or clean engine oil into each combustion chamber. Attach a socket to the crankshaft, and slowly rotate the engine through a few revolutions. (Make sure that you turn the engine in the proper direction, see a service manual for proper rotation direction.) If you hear any clanking, or harsh scraping, you should bring the engine to a competent mechanic. After verifying that the remaining systems are free of water (electrical, fuel delivery, air intake, distributor, etc.), re-install the spark plugs and wires, and attempt to start the engine."
