Well, I didn't throw a rock in this puddle before going through it
I just put my '88 really deep into some water, it was almost up to the hood. Thankfully my gf was there and was able to tow me out right away. Upon inspection, I've gotten water into the engine. It's realy dirty water, and that's what I'm worried about. When I took the air hoses off the throttle body, the water that was in there was heavy with silt and dirt.
Right now I'm letting it dry out. I've disconnected all the electrical connectors, and I'm about to drain the oil and take out the spark plugs.
I'm looking for advice on what else I should do to it before I try to run it again. Any help is GREATLY appreciated.
lol, yes she drives a ford. It's the 302 bronco listed in my signature (mine is the 351w). So here is what else I've found:
There was a quart or two of water in the oil pan. I pulled the vaccum module off the tranny, and the fluid that came out seems ok (how else should I check the tranny?) I haven't checked the diff's or t-case yet.
I pulled out all the spark plugs, one was somewhat wet and another was really wet (and somehwat muddy looking, actually). I'm going to pull off the upper intake to see if there is any water sitting in the intake ports in the lower intake.
And the carpet is really wet
As mentioned above, I'm worried about the amount of silt that was in this water. Is there some way I can clean this out of the cylinders before cranking it over?
Oh, more info: It was in the water for less than 20 minutes. After that I had her tow me home in neutral (about two miles).
It is common to get bent rods. You will also need to change the diff fluids, xfer case, and tranny. It got into all of the electrical connections. You will also have to remove the interior and pull the dash etc. All of that water got into the HVAC system, seats, padding, doors, and will smell...
believe me you could of easily bent rod... i know from experiance. i went through a hole going a little too fast and it was a little too deep... needless to say i sucked water into it and bent one of the rods. hopefully you are luckier than i am and didnt bend anything
Luck of the draw on whether you bent a rod or not. After letting the motor dry out really well, I'd turn it over by hand slowly (with the plugs out) and make sure there isn't any sort of hangups before trying to start it. Take it slow and step by step with your finger crossed!
I sprayed a bunch of wd-40 in the cylinders and then tried to turn it over by hand. There aren't any hangups, and it seems to turn ok. I hooked up my torque wrench, and i can turn it with the wrench set at 60 foot lbs, and it doesnt click. It was clicking with 50 lbs.
I'm still worried that there is some water on the walls in the cylinders. I was thinking about putting my soldering iron in the spark plug holes to vaporize the water out of there?
So do you guys think it's ok to try and crank with the starter?
Also, water got in the computer. Is there anywhere I can take it where they can test it to see if it's fried or not?
I cranked it over using the starter today. It blew out a little more water, and it is sounding ok. The pistons are traveling far enough up that they are coming up to the spark hole, so if they are bent I'm guessing it could be worse? Assuming the computer isn't fried, I'm going to try and run it tonight and hope all goes well..
Sounds like a stuck valve, you might tear off the valve covers and check out the valve train, if you have a problem, you might be looking at a head job.
It could be something as simple as a broken valve spring. Was that the compression in all of the cylinders, or just the one that you tested? Sounds like a engine tear down is in order however... Let us know what happens.
