With it running is always how I adjust them, this is how I can tell what the engine likes. How I adjust them is back off really slowly until it ticks. Then tighten really slow until the tick stops, then give it a quarter turn. I've seen guys go half turn, 3/4 turn, full turn, you name it. There's another trick called "Zero lashing" hydraulic lifters but since it involves more time and makes a mess I only do so on the ones I build and don't recommend it to others. I've learned so much about valve adjustment I can do it without oil squirting everywhere.
