sunk the hood and motor under water... what to do to fix

[elementtrev]

Ya so im new to the fourms, and dont know where else to post this...

so my buddies and i went mudding the other night and one of my friends went to far into the water and sunk the front end to the hood while running.. not good at all!!!! but now the engine has seized up and were trying to get it back runnin. his truck is a 02 explorer, we have been shootin all the pistons with pb blaster trying to eat the rust away form the cylinder. tryed drainin the oil and all the fluids. the truck sucked water up through the intake, to the manafold and into the motor, also brought it through the exhaust... we have been trying to break the seized pistons for the past day and are stuck between a rock and a hard place. really need to get this fixed. and wondering if anyone has had this happen and how they fixed it. any and all advice will be appreciated. thanks again in advance

Pull all the plugs. Try to turn over the motor by hand. If it wont turn, you have likely hydrolocked the engine and it is good for scrap. Yes I have done it before, and ruined a good engine.

If it is hydrolocked and damaged, then fix is to the replace the engine.

thanks for responding... unclemeat! and sadly your right, need to get a new engine

It's not just the rust, if you hydrolock an engine then there are likely bent connecting rods too.

you need new

talked to another buddy and he said the same thing about rods as you john. and we decided to rebuild the block.

For future reference...

If you go too deep in water and the engine stops. Don't crank over the engine! Get the truck pulled out of the water. Pull all of the spark plugs. Then crank the engine to flush out any water in the cylinders. Re-install the spark plugs and see if she starts.
