Totally agree with you Peter with regard to the number of parts in a 'push-rod' valve-train that can all contribute to engine 'clatter', vis-a-vie the modern over-head-cam layout (still over-head valve--I am not aware of them being superseded--yet) which has a lot fewer moving parts, and if the camshaft is belt-driven, a LOT less parts to make noise! I don't know if it is just the quality (or rather, lack of) of 'pattern' parts, but I can't seem to remember having to do much in the way of tappet adjustment in-between scheduled servicing when I worked on them as a job--I don't think it is just a matter of 'only remembering the good bits' either.
