does it go tick tick tick tick and when it warms up it stops or goes quiet?
its your lifters not getting enough oil
when u change your oil it will stop till that oil gets worn out
you will have to replace the lifters or it can also be a slack oil pump not pumping oil around the engine like it should

if noise is higher pitched and coming in on valve time...(2wice for every revolution of motor..ie: faster)...then upper end pressure is down due to sludge, wear , lifter failure, valvespring failure,rocker stud lifting out of cylinder head (kinda common) cam bearings failing (very rare)..oil pump bypass stuck open..and a few other possibilities... respond and we will go over lower end sound (deeper ,slower) and see what identifies your issues .... miles

I bought a used 05 Silverado and it had started to get a ticking noise. I had one of the lifters replaced as it was determined that it was sticking. A week later the oil pump went. Replaced the pump and have not had any issues since.

Your lifters have become clogged over the years. Its only after the oil warms up and thins out does it allow oil to "pump up" the lifters. That's why it goes quiet after 5 min. There are several different brands of additives on the market that can fix this problem ,unless you have a more serious mechanical problem, which I doubt.Check your local auto parts store for the additive. Just add it to your oil and "wham!" problem solved. Good Luck!
