Its tough to say but it could be like you suggested your throwout bearing but it could also be your mainshaft bearings getting a little tired.

If you push the clutch pedal to the floor the noise should stop and as you let the clutch out ( In neutral) you should start to hear the noise. chances are that its the throwout bearing though.

could be the pilot bearing in the flywheel going. Mine made a groan when the clutch was being released. Pilot bearing was shot.

my release bearing squeaked intermittently, then right before it failed it began squeaking all the time, exploded about 75 miles later!

only does when its in gear and you let the clutch out at the right spot. when i press it to the floor it will stop . I'll get a slight shudder out of the drivetrain. the car shifts fine and wthe week b4 i adjust the clutch to spec. the clutch will will grab at the very top of the pedal . I was told this is normal from another 911 owner. i guess ill start saving for a clutch over haul.

I'm sorry but it sounds like the tranny to me. The good news is that I am not an expert...

ok talked with my friend a retired Porsche mechanic (Jim Long)in the Warrenton ,Culpepper VA area. Great all around guy and a wealth of info. He says the clutch is probably over adjusted. I adjusted the back fine ,but didnt set up the pedals right . So hopefully i can readjust the clutch pedal and everything will be ok. I'll let you know how it turns out and if im still gonna make that trip to clutchville. hope not. thanks for all your help in my downward spiral.

Try to picture the speed of the components related to a gear change, then associate the noise/speed with the component. Does the sound match the engine speed, the input shaft speed or the difference between the two? A pilot bearing will usually make noise as the clutch disc slows to rest when shifting into gear when stationary (difference between the two). A throw-out bearing noise will match engine speed. A mainshaft bearing noise will match the speed of the selected gear (i.e. upshift/downshift)
