gentlemen bit of a story so have patience. a noise developed in the vr the other day. stripped the belt off because it sounded like a bearing. i found it was the alternator. got a price£143 plus vat. decided to strip it down to have a look and i found it was the plastic runner that the bearing sat into that was located in the housing. anyway i got a new one and fitted it and it ran perfect, on idle. now i dont know if these two items are related but i took it down the road to test drive it and it almost felt like the engine was about to seize and the oil light came on briefly.then it was fine
