Whats the Rocker arms ?
Rocker arms are typically located between the pushrod and intake and exhaust valves. They are pushed and pulled by pushrods to “rock” up and down, opening and closing the exhaust valve and intake valve of the combustion chamber on engines with a camshaft below the engine. Pushrods move up and down as the camshaft below them rotates, driven by the crankshaft. Then power can flow from the combustion chamber of engine through various parts to the wheels to put the vehicle in motion.
