Ford 6.2 ticking sound

First sound (kinda like a vibration or a buzz) is the purge canister, replaced in April by my local ford dealer per a TSB. It does it again, 4,000 miles later. Dealership claimed this noise was not there the second time around.

Second ticking noise up to 3,000RPM is undetermined. It was deemed "normal operating conditions" by the dealership, yet there is no way a gas engine should sound like this unless theres a valve train issue.
