Has anyone ever seen this problem before, or any advise what could be causing it?

The OEM crank pulley incorporates a rubber connection which is flexible so as to absorb torsional vibrations in order to protect the crank shaft from high frequency stresses. It would appear that this has become detached and your pulley is therefore running off centre. A replacement pulley is most likely the answer.
