Hey guys and gals, new to the forum. I'm having a Chirping nose when my motor is warm and it sounds as though it's coming from the valve cover, drivers side. If you stand at the front of the truck you'd swear it was the fan or idlers, the serpentine is riding dead center and as you get closer and up into the motor it's more in the valve cover area, maybe even towards the intake a little..
