Tapping Noise

Hi,
Have just recently purchased Micra DCI 1.5 2009.107,000 miles with all service history stamps,last service in March also had the timing belt changed.This noise does not happen when ticking over but does as the revs increase and not so much top end.It can be heard quite loudly from inside the vehicle.
Please dont tell me its the crankshaft on its way out,
Thanks
