Setting valve lash with new, non filled hydraulic roller lifters

So if I am reading this right he was not paying attention to preload at all... just reefed down the adjusters until they stopped moving and was actually opening the valves?

You don’t even have to “reef” them down all the way. Adjusting them with the lifters filled/pumped up will hang the valves open. It’s bad practice.
