Citroen relay noise

This vehicle was presented with a noise coming from the gearbox, when we removed the drive shafts and dump plug the oil was like silver paint, we took the gearbox out and it needed a flywheel and clutch. We sent the gearbox away for repair and the customer was very lucky. The bolts holding the pinion wheel on came loose and was lathing away the internal of the gearbox. Caught in time.
