When I start up the car after not driving it for a while, or in the morning when it's cold, i'll start to hear this nasty grinding/crunching type of sound after a few seconds to a minute of the car idleing in neutral. It's coming from the clutch/tranny area, and whats even weirder is that the noise stop's when i press in the clutch!? At first i thought maybe it would be a bad throw out bearing, but wouldn't that have the opposite effect? Sounding nasty when pressing the clutch. Oh, and this sound that i'm experiencing will go away after a couple mins of driving or i guess until the car is warmed up? I don't notice any difference in the feel of the clutch, no grinding of gears, etc. Everything "feels" ok, but it sounds horrible for a few minutes. Any ideas?
