- If the noise occurs with the clutch *engaged* but not with the clutch
- *disengaged* you can rule out the release bearing (usual, and cheapest
- to fix, problem). This leaves the clutch/flywheel/needle bearing
- assembly as one possibility. The other is the transmission. 8{(
-
- I would suspect the latter as the noise seems to be related to whether
- or not the trans shaft is turning (clutch out) or not (clutch in).
- The needle bearings in the flywheel are only turning when the clutch
- is disengaged (pedal in) so that is out. The rest of the clutch is
- held together pretty tightly by all those springs. So it may well be
- the trans. As the engine warms up in neutral the trans oil gets
- spashed around and may finally lubricate whatever is rumbling, so the
- noise goes away. Have you checked the trans oil level?
