ok, i think i got AUDIO, and a pretty lousy video, but it is the sound im after....take a listen. its not the best sound quality, and it is loud because i stuck the camera right down in there. camera location is just above the spark plug closest to firewall, on drivers side. i used my stethescope, and it is defenatly loudest there also. i put the scope in the indented groove on the "valve cover?" just above the spark plug. i also stuck it in the indent around the spark plug. both places it was very distinct tapping.
so, if this works, heres my audio clips.......

ok, thats not working....posting the video, that is.....ill try something else
