No adjustment, but shimming sometimes
The valves have hydraulic "lifters" that have a specific amount of travel. Sometimes there is wear on a rocker arm or the "shim" gets cupped and the gap exceedes the travel of the "lifter". Then they make a tapping noise. In such a case the 'lifters" need to be re-shimmed to set a base position.
