Need help SVG gang!! Have a strange noise coming from the rocker/valve train area over the # 2 cylinder. Using a stethoscope on top of the valve cover bolt closest to this cylinder one can hear a noise that sounds like two metal object coming together with little or no lubrication. Oil pressure is good. When started cold there is some lite lifter clatter (same general area) that stops as engine warms. The other sound remains constant. Car runs fine, no rough idle and shows no codes. Thks for any help, advice or suggestions.
