Had s60 2004 volvo timing belt/water pump replaced. Check engine light comes on after one week for the 02 sensor but a loud high pitched(sounds like an idler belt) noise is previlent when car gets warmed up. Noise lessens after 2000 RPMS. Shop owner is saying the cam bearing could be bad. Could the timing belt change have anything to do with this?
