Whistling noise HELP

[SantosG]

Hi everyone, 

looking for some help and advice! 
i have a 2011 Nissan Qashqai 1.5 

I have noticed there is a ‘whistling’ noise coming from engine area, it seems to start once the engine warms up and Ive been driving a while, I then noticed when the clutch is engaged the noise stops … foot off clutch it starts again, but the whistle itself can be intermittent. I have been told it is the ‘throw out bearing’ but upon doing some research it could be something else and something alot less costly… has anyone had this or can advise?? 
I have limited funds and I am wondering if I should question mechanic and maybe try other options first. 
 

any help would be greatly appreciated. 
 

(I have video of noise just not sure how to upload yet!)

First thoughts....do you rest your foot on the clutch pedal at all?

If so, then you have worn the release bearing and this is the reason for the sound.

As long as it doesn't get any worse then it should still be good for a while

Thanks for replying. 
 

new clutch in, it had already been making sound for sometime so just did it rather then waiting for it to completely!
