did some searches nothing resembling what i noticed tonight... I popped my hood today after work while the car was idling...just checking stuff out. I noticed a buzzing sound coming from the passenger side bank of the motor. it sounds like its coming from somewhere near the valve cover but towards the front. maybe by the cam gears. I really cant tell, just in that area.. anyways, i thought it may be normal valvetrain noise, but its only on that side. and its a buzzing sound. sounds almost electric. Funny thing is that it will completely stop every once in a while.. but then start again. my question.. IS THIS NORMAL? first time ive noticed it. The engine runs fine and i have no issues, that i know of. None of the reported problems etc... I just thought it was weird...

you can get a stephoscope for engine use, it would pinpoint the sounds location (has a thin tube rather than a disc or wide cone) I can' say engine buzz sounds familiar (no pun intended)
