Which of the following is NOT a part of the valve system?

Cam lobes
Pushrods
Ring
Valve lifter

The correct answer is: Cam lobes

The correct answer is not a part of the valve system because cam lobes are not directly part of the valve system. Cam lobes are the components of the camshaft that interact with other parts such as lifters or rocker arms to actuate the opening and closing of the valves in an engine. On the other hand, pushrods, valve lifters, and valves are all essential components directly involved in the operation of the valve system in an engine.
