I have been noticing a sqeaking sound coming from the pulley area of the motor the past few days. Today it started making a clicking sound, then all of a sudden, there was a loud whirring sound. the sound seems to match engine speed as it sounds different when pushing the gas.

what could this be

 

Could be any of the pulleys:

Alternator pulley
accessory belt auto-tensioner pulley
accessory belt idler pulley
timing belt idler pulley
timing belt eccentric pulley
power steering pump pulley

 

having the same problem, check for my post i put a video of the noise, check it out and if you figure it out let me know
