I hear a "Chatter Noise" from the front of the engine, I have lifted the car up and listened all around and I have pined it to FRONT for sure.
I am not kidding when I say I spent over an hour listening all over the car. I do not hear the noise coming from inside the motor.

I am starting to believe its a Pulley starting to go bad, I noticed that it get louder as I rev the car. I have read that it can be the Idle pulley but I really want some advice.
