I have the same problem...thought it was the idler so replaced.....still there...turns out the stock crank pulley can cause this. I have used some belt dressing on it and it works for a while. I don't really drive the car so its not a biggy for me.....

^ That. Make sure if you go for re-greasing you clean everything really well and get all the old grease out and such, if not chances are it will return.

New pulleys aren't always greased very well from the manufacturer.
