Repairing More Flood Damage

[ferncreekjeep]

Hey - no one will reply to this thread in the Ford ZX2 Forum - its pretty general. You guys on the Jeep Forum are way more helpful/insightful anyways.

Here it is:

Please help - sorry for so many questions...

There was water in the two right cylinders - I got most of it out. I also sprayed WD40 into all the cylinders. There is still some visible dirt on the pistons - is there any way to clean the cylinders out better (a brush, rag...)?

What is the best way to clear the fuel lines (compressed air)? Gas tank has been drained and wiped out (it was more than half full of water). Should I put a new strainer on the fuel pump module or just see if it will start before putting any more money into it?

Also, there is a constant buzz/ring (from the radio speakers) when the ignition is turned to aux and start - does anyone know why? The radio does not work - could that be the reason for the constant ring? The pcm was fully submerged - could the ring be a default for a bad pcm? The engine/starter will turn, but I haven’t tried to start with spark plugs in.

Any other suggestions would be greatly appreciated!

Thanks

A clean rag will work for the cylinders themselves, both to clean and get the water out. You said there was water in them, to me it sounds like you had the head off?

For the fuel lines, once you've refilled the tank with gas, I'd think you could disconnect the line somewhere up towards the front, and turn on the fuel pump for a few seconds, but watch your eyes. I'd replace the screen on the fuel pump, and maybe even the pump itself, since it was submerged in water.


I'm no good at electronics, other than to tell you that a buzz/hum is often caused by grounding or shorting. Since the wiring harness (and PCM) were submerged it's a good bet that some of the electronics are corrupted.

If it had that much water on or in it you will have a lot more problems than the raido.

If it got to the pcm it usually wipes it out along with the wiring and a lot of other electrical stuff.
And some of them may crop a year or two later.

Was it salt water or other?
How long did it sit in the water?
Do you have the heads off of the engine?

It was creek water/storm run off, and a little dirty due to the high flow. It was submerged for about 6 hours (2-3hrs at peak water level).

The head is still on - I took the spark plugs out and can see the dirt/ not sure if there is any rust. There was no water in the cylinders until I turned it over - water was evidently in the intake manifold.

Hmmm, maybe park it on an incline (or jack up one side) and suck the water out of the cylinders.

I kinda wonder about that dirt in there but.
Well blow them out and oil them up and hope for the best.
Time will tell.
Good Luck

Just three things:
* as Fred said... disconnect the fuel line and have someone turn the key on and let the fuel go into a jar. Pump as much gas in there until clear...the water and gasoline will separate.

* squirt some WD-40 and then a light weight 5w-20 engine oil (a couple of squirts with a squirt can) in all the cylinders and crank over with all the spark plugs out first... get as much stuff out of there first...then fire it up and the debris should burn up and go out the exhaust

* Take the radio out and dry it in the sun and then test it.
Also ..Remove the door panels and look at the speakers, the water might have rotted the speaker paper away ...or caused a "shorting" in the speaker wiring ....you might have to clean inside of the doors anyway
