Ok guys I searched but nothing seemed to go along with my problem. When the car idles I can hear a faint tap coming from under the valve cover. Now on a free rev there is no audible tap, but when riding in 1-2 gear if givin more than half throttle it taps like a mofo. what could this be? I do not think it's rod knock because it is coming from the middle-upper portion of the valve cover.
