Find another mechanic. The dealership guys don't want to talk to you if you use non-OEM parts. Did you use the cheap Chinese pullies? Sometimes those bearings go bad in fairly short order. Get a mechanics stethoscope like this one and locate the source of the noise:


Might be that the timing belt is too tight.
