When to adjust valves? oil change? On recent motor.

I used to worry and worry about adjusting valves !! After wearing out valve cover gaskets and wasting a lot of time. I figured out the valves will let me know when they need to be adjusted !! And it was pretty amazing really cause they didn’t need no where near as much adjusting as I was giving them lol !! Long story short .. When you hear valve train noise adjust which ever cylinder it is ! Rock on down the road !!
