So after many nights of toil I have completed the full service, cambelt and general spruce up of the spider. It will be off for MOT this week. Trouble is its got a whine from the belts like they are running too tight. Cambelt tensioner pointer is on the mark. Waterpump changed.tensioner changed. Idler changed. balance belt changed with tensioner and seals. can do just over 90 degree twist on the balance belt and the pointer is on the mark. So what is whining. And whining quite loudly too. Is it all just settling in or have i missed a trick here?? i haven't changed any of the aux belt stuff but it wasn't making any nosie anyway.
