Have a similar problem with my integra. The noise would always go away if I
depressed the clutch but was there even at idle with the clutch out. It
would also do it coasting with the clutch in (basically anytime the trans
was turning). Mine turned out to be the clutch housing bearing (the bearing
in the trans nearest the clutch). I put up with it for about 6 months as it
gradually got worse before I finally took it apart the other day. The wire
mesh that spaces out the bearings was completely ate up. About $27 for the
bearing itself but lots of labor to replace.
