I hear the loud knock we are talking about like 3 times in that clip, but I hear a lesser tap more in sequence with the RPM of the motore in the backround. Maybe this is stupid thinking here but is it possible that a broken exhaust pushrod or rocker is allowing the cylinder to fire and that loud bang is a backfire thru the intake? Is that possible or am I stupid? Its not hard to yank valve covers...
