Hello,
I just had vauxhall replace my cambelt (full kit) water pump and v belt. Although the car runs great and idles nice and smooth i notice a slight vibration/rattle on acceleration and on overrun.
This noise does not happen if you rev the engine out of gear. When the noise does occur if you dip the clutch it stops at once. As far as i can tell the noise seems to be coming from engine bay (sorry to be vague) as appose to floor pan or wheels.

Any help would be appreciated.
Thank you
Andrew
