Water in Everything



1996 Ford F-350 7.3L Powerstroke with 352,000 miles. Could use some help here. Got the truck stuck in a fast moving river for about a day after my rear passenger side valve stem was knocked off by a rock. Due to the location and timing it took some time before I was able to get it out. Water never entered the intake, but after it was towed out there was water in the oil, transmission and transfer case. Truck still has all working electrical. I replaced the starter, but truck still won't turn over. When you turn the key there is no sign of it trying to turn over. The only time the truck would never show signs of trying to turn over is when it doesnt think its in park. (Previous owner messed with the shifter and now its finnicky, usually have to shift into drive then back to park to get the truck started.) I can freely turn the crankshaft. Any help is appreciated. Enjoy the pictures!

you were in deep enough that the PCM and maybe the IDM went under water?

do you get a WTS light?

When it was pulled out both were dry. I have no lights on. Only the front of the engine got wet due to the constant water splashing up on it.

It’s called a PowerStroke bud, not a PowerSwim 😆 just bringing a little humor in the mix .. That looks pretty bad

I would suggest keeping your updates and questions in one thread so everyone can see the progress and help you work through the issues to get your truck running again.

in your other thread you said the oil was milky again after you started it. I would change the oil again and this is probably one of the few times i would consider opening the oil rails and hpop reservoir to change the oil. You could have some water in those areas as well from cranking the motor over. I would not want it moving throughout the system. Change it all and start fresh.

with it starting for a minute, i feel like that is a good sign.

did you pull the IDM and PCM to make sure water did not get into them?

how long were you fording water until it died, and how long did it sit until it was rescued?

My bad! Still new to the whole forum thing. When I pulled the truck from the river both the IDM and PCM were dry but I can pull them today to double check. The truck was running for only about 3 minutes while I was going through the water, but once I realized it wasn't going anywhere I turned it off. No water entered through the intake, but I believe just the force of the water against the truck forced its way in somewhere into the motor. The truck was in the river for nearly 24 hours before I was able to get it towed due to the timing and location.

Update

Removed passenger head, this is how it is. The rust is able to be removed with the swipe of a finger.

Reminds me when me and my boys got stuck in our 00 f250.






I would change every fluid in the truck, change the MLPS (sensor located on the transmission on the driver side shift linkage) and maybe even the starter.

My 88 F150 flooded in Hurricane Harvey, so I get your pain here.

Pull seats and carpet. Get it clean and dry there.

Service axle(s) as usually the vent hoses are broken off, but water was so high it may not help anyway. PS too. ATF given.

UPDATE:

Have replaced the MLS Sensor, starter, all 8 injectors, valve cover wiring harness, glowplugs, and all fluids that had water in them.

Truck is attempting to start, and with some starting fluid she starts up for a second or two, revs up without me touching the accelerator, and then dies.

Any more ideas is appreciated.

Make sure not using glow plugs and starting fluid.

Plug it in for a while. I bet the fuel system needs to reprime since injectors were out. Did you drain the HPO rails?

If so, I would pull the glow plugs so you can spin it fast and easy with no compression fighting you.

When you say no glow plugs you mean to remove them, or just unplug the battery to them?

I didnt have the tools to fully drain the oil rail, but I did siphon everything out of them.

Unplugged at least at the relay. I have also heard it is better to have it spinning before inducing ether.

It will take more cranking to refill the HPO system. Hot oil flows better so plug in the block heater.
