I guess I would have to be there looking at it to tell you what it is, because somehow we went from "intake popping" to "loose valve cover" to "injectors".... which all usually make different sounds. a pop-corn popping sound from the intake is usually cam timing being off, a "clacking" sound from the valve cover is either the timing chain/guides or something loose, and a small "clicking" sound is injectors.
