I've got a 95 mk3VR6, recently started to get a strange rattling noise from the engine, close inspection shows it is coming from the alternator/tnsioner area. My bro reckons it might be a nackered bearing in the tensioner, i don't have a clue, pretty new the the VR engine. Would anyone know what this is, how simple to fix and how muich to fix? If you need any more details please let me know. thanks,
