Bad valve, sticking

something in cylinder hitting valve, crank shaft bearing loose. bad timing

Maybe the rocker broke (say due to fatigue) and the broken parts and contaminated lubricant then scored the cam? Very difficult to say without seeing the thing in the metal.

Since the valve train is at the terminus of the lubrication system I would first suspect inadequate oil supply at this location.

Not enough info. Need more detail on other similar parts damaged or just this one valve train, etc.
