Slight Whine/whistle?

[mazgtr]

R32 GTR.

Started a a few months ago.

Once in a while ill get a high pitch whine/whistle, sounds like its comming from under the bonnet, near the front passenger side (near turbo's) but very very hard to tell for sure.

Now this happened only 1-2 on a 30min drive yesterday, it starts as soon as the revs pick up, and rises with the revs, getting louder. Its worse the higher the gear and gretter the load.

The car otherwise is running fine, with no rough running (so i dont think its a air leak, pre-engine).

Does anything in a GTR's drivetrain sometimes make a similar occasional whine?

Or would a leaking exhaust/turbo gasket have similar symptoms?

Just wanted to see what everyone thought before i book it in to mechanic..

Cheers.

at a ruff guess i would say fan bearing..

I have had the slight whisltleing from a gasket leak but this was loud only while engine was cold

Ok, this sound is only audible with the passenger window down, the radio off, and if you lean forward and squint. So in other words not very loud, but still just a bit concerning. Ill grab the WD40 and see if i can see anything under the bonnet. I do remember when my air-con belt started to die it started to make a pretty horrible sound, it eventually snapped before i could located what was makeing the noise. I havent changed the other 2 belts yet, but the timeing belt was done only 10,000km ago.

Just one of those annoying little noises..

Cheers.

Can you switch your climate control off and check if the whine is still there? I had too a whine of some sort and was convinced it was my tranny, after switchign the climate control off I realised it was a fan for the air con lol

Ok sweet Sir-D, ill give that a go aswell. Most of the time i cant tell what my climate control is doing as the little lcd panel display goes on vacation most of the time!! LOL!!

Cheers for the suggestions guys...
