If it was the cam, would I hear it louder when I removed the oil cap?

I'm not grasping on the reason to suspect the cam? The entire problem has been with the single injector.........nothing in the process suggests the cam is the issue in any way.
The engine offers a very light injector knock at idle...........sounds more like a 617...........rather then the typical sewing machine sound of a 60X engine. Above idle, the problem is eliminated.
Sometimes these engines do exhibit lifter noise which will be characterized as a noticeable "ticking" sound, most easily heard behind the wheels in the fenderwells.
