Can You Hear Your Clutch In Neutral?

[pgilliam1]

At idle (inside the car and doors shut) I can hear a whirring sound when I let out the clutch pedal in neutral. It's not loud, but I can hear a soft whirring sound. It goes away completely when the clutch pedal is depressed (I believe the PO put a racing clutch in this car - if it matters). Normal - Not Normal?
Thanks,

Maybe your throw-out bearing is making a little noise. Nothing to be worried about I think unless it's dramatic.

I have that sound too but only noticed it in gear, it might do it in neutral too.

It is not the clutch you hear. It is the primary shaft rotation in the tranny while in neutral = normal.

I just had my Acura dealer install a new OEM twin plate clutch in my 1991 after a defective clutch or bad installation a little over a year ago.

The new clutch works much better than the old one but, after a couple of weeks of driving, it began to whine when the clutch is depressed. The noise disappears as soon as the clutch is released. And it does not matter whether the transmission is in neutral or any gear - as soon as the clutch is depressed it makes the noise.

I am going to take it back to the dealer but, until I do, does anyone have any thoughts?

I got the same problem, I hear it a lot when I let off the gas at about 4 or 5000 rpm in 1st or 2sec gear.

Bad throw-out bearing or installation. TOB need to be greased properly, otherwise it can be actuated off-center by the lever.

If the mileage is about 100k the countershaft-bearing (inside the tranny) can be worn out and cause this sound (grinding noise) during decelerating in 1st and 2sec gear.
We had some of such cases here in Germany and Switzerland and recommend to replace this bearing during clutch install.

Do you have to open up the trany to get to the bearing or can you just drop it and change it out?
