I am getting increasingly concerned, and deafened by a whirring / rubbing noise from my cambelt area. It is quiet for the first few minutes but slowly gets louder as the engine warms up.
It is not really a whirring or rubbing noise, its sort of a belt noise. I wonder, is this a common / known problem, what is the most likely source. Could it be the tensioner bearings? The belt itself?
The tension is correct, the belt appears in perfect condition, does not appear to be fouling anything and was only replaced last year [less than 1000miles ago :-o]
Appreciate some wisdom please.
