Thanks for your comments John and Ian
Yes I agree that the measured difference in noise level is about the point where a difference can be noticed. I think the slightly harsher sound of my car catches the ear more.
Ian I did not measure the end float or timing gear backlash. So that may be a contributor. The sound appears to come from the tappets rather than the gears.
When I get time I will measure the tappets, but that will have to be a while away.
