List 10 things a camshaft might do in an Internal combustion engine?

Might be timing adjustable by the computer using oil pressure. Might need shim changes when valves where. Might need valve adjustments when the valves where.

Might throw a code if the oil is low causing the cam adjustment mechanism to not work. Might spin a lobe down and stop a cylinder from working. Might break. Moght get out of time if the timing chain jumps a tooth.

It open and closes lifters that control the valve train.
