01 F-350 7.3 fully submerged at boat ramp

[skeeter101]

Ok guys, I am desperate. This is how it went down. Was fishing a tournament the 1st of Dec, was launching at ramp, in park and emergency brake on, came out of gear and was fully submerged in 16 feet of water for about 4 to 5 hours. The truck sat......yes sat for two months before anything was drained.
at the end of today......differentials are done, engine been drained, new filter - trans same thing, transfer case. All flushed and new fluids.

It shorted the starter, so had it rebuilt and have yet to put it on.

Someone advised me that I remove the glow plugs and turn the crank to force out any water that may be in there.

I have removed the valve covers and all eight glow plugs and I am still unable to turn the crank. Another person suggested that I install the starter and bump it to force it out.

I want to mention that when I was removing the hoses from the turbo, there was ice within the bottom hose. I actually had water in every section connecting to the turbo.

Could ice be causing me not to be able to turn the crank by hand?
Could water be frozen in there somewhere?

Please ask away......I will tell you guys everything I know about this truck and what I have done...."and haven't done"

thanks

the cylinders are probably rusted to the wall. I think you may can put a big wrench on the crank shaft and try to break it free. but i may be totally wrong?

[skeeter101]

thanks for the response,

I can move the crank about a 1/4 of a turn either way.....

is there a certain direction that I should turn? Standing in front of the truck, should it go left or right?

Also, when I drained the oil pan there was about 2 to three gallons of water that came out before the oil started pouring. At first I didnt think that was much......but I have found water everywhere........so that is why I am trying to eliminate all I can....

but I want to make sure there is no water on top of the pistons and that is why I removed the valve covers and the glow plugs.......

any other advice out there?

why'd you wait so long to drain everything?? salt or fresh water?? was the truck running when it got sunk

[skeeter101]

I was told by my "former" mechanic that the fluids had been drained and was told he had done work to it.

With work, the holidays and all that, I really didnt get to go over there until a few weeks ago. That is when I had the truck moved and I have been doing the work myself.

All the oils were drained approx. two weeks ago.

Yes the truck was running when it came out of gear and went into the water.

Fresh water lake.......

The PCM was bad......have replaced it

When you say water was frozen in the turbo line (assuming intercooler piping?), do you mean the truck is still outside in below freezing temps? Iced up in the cylinders? Did the block or coolant freeze?

[chrashd]

You can spray some Blaster or any penetrant into the cylinders and turn it to work it in, then spray and let it sit a few hrs and try again.I've seen people get away with this before,but the work was done as soon as the motor came out of the water!!!!

[skeeter101]

Yes the lower piping on the passenger side. And I am certain that it did freeze, it was outside the entire time my "former" mechanic had the truck. I have it inside now.

So to answer your question.......probably so.

My boat ingested water this past summer and we let it sit for three days before i went to run a compression test. When i started pulling plugs water SHOT out the plug holes , after the third plug and a test showing 5lbs on the first cylinder i just left alone. Anyway 3 weeks later ( right at a month of water in it ) when the builder got it , the wrist pins were completely siezed and you could turn the pistons 360* and the rod wouldnt budge. I will be amazed if it runs again without tearing into it....

I've never submerged a diesel but have drowned an atv or two. Things aren't pretty inside when they inhale water. Obviously water doesn't compress and the result is normally bent internals. Hope for the best of luck but man....doesn't sound good.
