Hey guys.

I've had a whirring noise from my engine for a couple months, symptoms:

The whirring noise is audible during idle with clutch engaged (pedal up),
as soon as I disengage the clutch (pedal down) the whirring goes away.

I thought due to the symptoms it would be the Imput Shaft Bearing, but through more thought and in talking with fellow mechanics, I am not so sure.
I'm thinking it could possibly be the TB, in that when the pressure is put on it (disengaging the clutch) it takes up the play that is making the 'whirring' noise.

In your experience with the Maxima's, which is more likely? If it is just the Throwout Bearing I'm not as concerned about it for now, but an Imput Shaft Bearing does bother me, and I'll have to push the engine pulling to a lot sooner than I would have liked. Any comments/opinions?

Please discuss!

Matt
