Well sometimes my car makes a weird whistleing ,screeching noise when i sit at idle with the clutch pressed. When i let off the clutch it goes away. And it happens randomly, but the times it is happening i also feel a weird crunch/obstruction in the clutch pedal feel. Its a FMS king Cobra Clutch, thanx....btw my mechanic doesn't think its a throwout bearing...its pretty loud too im gonna see if i can get a video of the noise
