Are you missing the rubber covers between the wheel arch and engine bay?

Is it muddy water? It may be crap in the rear drums.

the covers are still on between the engine and wheel arches. The sounds coming from under the bonnet not at the rear... Any more ideas? Last time it dissapeared after 20-30 minutes of constant driving (speed sitting on 100kmph). Tonight, its still doing it but I haven't driven it for a long period of time, just 10 minutes here and there, i just went for another drive and its still doing it. Its not as loud when idling but when your accelerating its high pitched sort of squealing noise and again when staying at constant speed its not too loud, louder then what it is when idling but not as loud as accelerating. Is it a chance it could be coming from the turbo? I have a snorkel though so I don't know how it would be able to be that.. Also when i went through the water it wouldn't happen straight away it would 30-50 seconds before it started. I went through one puddle and it started after the 30-50 seconds and then through another. When I went through the next one it stopped for about a 1-2 minutes and then started again... Any ideas would be very greatly appreciated, I'm starting to get a bit nervous :\

Alternator bearings? How deep was the water? Have you looked for the noise with the bonnet open at idle?

 

[Jason]

Also may be belt tensioner pulley bearing?

Mine makes a light squealing noise when the belts are cold. After the engine gets a little warmth in it the thing quietens down. Could yours be belt noise, or are we talking "finger-nails-on-the-blackboard" kind of squealing?
