Is this bad or just what I have to expect?

Lol I can't form any opinions on other kinds of trucking. I'm still new to this forum. Things like replacing the doser, EGR or sensors don't really concern me. What does worrying me is the issue with the cups in the head leaking and the overhead being starved due to sutt and damage to the cam. I think I've watched most of Rawze's videos and It makes me feel like all these engines are prone to failure. I don't feel like I can buy one of these engines without pulling the valve cover. From the outside how can I tell if a cup is leaking? Every one around here is saying don't buy anything earlier then 2014.
