I thought he same- the cam gear run out could be an issue but it looks true in the video they took. Its a real reach but it might be possible the cam gear teeth (or distributor gear teeth) might not be machined right such that the cut depth & width of the teeth changes along the circumference of the gear effectively pushing against the other gear when a narrow cut engages the other gear...like a said...its a real reach.
Anyway, listened to the videos of the knock again last night, to me, the sound and timing are that of a bad lifter tap..but its a roller so???
