Exclamation Help: Odd noise while idling

After a few seconds, maybe 20 or so, while idling with the clutch in, and in gear, I hear this kind of scraping sound for about a second, then it goes away. Seems to come from tranny area. Clutch is good, no increace in revs or chattering. Any ideas?

In reply to the original question, it could be a slight vibration from the engine thats causing your heat shields or something to vibrate, wich can sound like metal scraping. An audio clip would be great btw.

i bet its your throwout bearing, it probably isnt spinning freely and is scraping on the pressure plate, ive had hte same thing happen. Replace it!

eh?

the pilot bearing doesnt speed on load clutch disengaged (you'removing) because the flywheel's rotational speed is the same as the tranny's input shaft's rotational speed
