Hello all, recently my BRZ has been making a high pitched whine noise coming from the front. When you increase the RPMs the noise is more noticeable, and it doesn't matter if it's in neutral or in gear.
Took the belt off to rotate the pulleys and noticed 2 of the pulleys sounding different. Do the idler pulleys sound normal to you guys?
