the bearing in the tensioner pulley is ok but the bearing is not a tight fit in the plastic pulley,it seems to be floating inside but not removeable as the pulley moulding is smaller than the bearing OD.quite how its assembled i do not know unless it is a one piece assembly when manufactured.the bearing in the idler was replaced as slightly worn but had little effect.
thanks for info,will check on those other parts when i get the chance,with regard to the tensioner pulley that was not new,its how i found it when i took it off so maybe i will replace it as well.Noise does sound "metallic"so timing belt bearings could be the source,also the noise is more noticeable via a screwdriver held to the ear and placed on the alternator so will have a look at that.
thanks for now,Brian.
sorry have not had opportunity to check car since last message,will reply again as soon as i do.
