I've been herding this noise that sounds like I have a supercharger, at idle and now in every gear. I've read around and have come to the conclusion that maybe it's the Throw out bearing/ slave cylinder. I replaced that paid a crazy amount of money but I replaced it and to my surprise the noise is still there...

has anybody else come across this problem and if so what have you done to correct it? I'm sure other bearings come into play but before I go spend even MORE money I'd like some help to pin point what it is. Any help is greatly appreciated. Btw it's a 6spd ml.
