Rattle in the top?
when 7.3 is idleing there is a rattle in the valves. If you increase the rpm's it goes away. How or can I quite this down at idle? Just put on 4" exhaust and would like to hear the new tone at idle.

I am leaning to injector noise as well. HPX crossover, running synthetic oil, both of those will make a big difference. I also run additive in every tank and can tell a difference in noise if I don't for sure.
