Grinding/buzzing Noise When Driving

[khoala]

theres a buzzing/grinding noise coming from somewhere under the car everytime i cruise at EXACTLY 1600 rpm. as the revs climb and it hits 1600rpm, the buzzing begins but as soon as the revs increase past 1600rpm, the buzz goes away. i thought it was clutch related but ive just changed the clutch today and serviced the car but the buzz is still there. i cant pinpoint the exact location of the buzzing but its around the gearbox/rear engine area.

anyone have a clue what it could be? (i dont think its the synchros as the gear changes are smooth) any help is appreciated, thanks guys.

I believe I'm having the same drama. When the car warms up, I have a particular bzzzzz sound when putting the clutch in to select (especially between 2nd and third). It has been doing it for the last 10,000kms, so it's obviously not too serious.

Did you work out what was causing your noise?
