Water in Engine

[steve1001]

Hi Guys

Its been a bad day. I feel like a right idiot.

I went through a ford.  I got half way through the 'lake' and the car ground to a halt. The water was about a foot deep. The water was up to the front door lower rubber and I could not get out without wading in it!
Long story short, a farmer in wellies pushed me out (strong as an ox he was).

I tried to start the engine, but it turned just a fraction, the instrument panel lights went dim, and the starter motor just stopped. The starter motor barely moved by the sound of it.
The interior lights, heater blower, wipers, indicators etc work, so I have got good electrics by the look of it.

The AA relayed me home. The AA guy said the engine was 'f**ked as it had water in it. He said that the engine maybe locked up because something has got bent. Water does not compress so I hear what he is saying.
I've just took the air filter out. It is dripping wet. There is evidence of water in the tube beyond the air filter housing.

Have any of you had experience of this situation? Any suggestions where I go from here to further investigate myself.

All suggestions welcome. Jeez, am I pissed off.

Thanks

Steve
