Pulleys are fine... otherwise when giving gas, sound would get louder... seems to be coming from passenger side, front valve cover area...

one car at a time

Sounds like either an exhaust leak or a pulley rubbing something...Sorry I can't be more helpful. Generally exhaust leaks are worse when the car is cold.

Its random, actually rarely happens on cold start... Positive not exhaust leak though.

Use a automotive stethoscope to help pinpoint where the sound is coming from.
