whirring noise when in neutral.

There is a faint whirring noise when T350 is in neutral. It goes away when the clutch is pressed down?

Any ideas. Tends to happen once the car is warmed up.

Thrust bearing, and you will find it with the majority of manual cars.

Also known as the clutch release bearing I believe. Not serious but fiddly to fix.

First motion shaft or layshaft bearings can cause this, noise worse when hot due to oil thinning.
Disengaging the clutch stops them turning.
