The rocker arm works with the camshaft, pushrods, and valve bridges (if present). When replacing rocker arms, it is recommended to inspect all these components.
A broken or excessively worn rocker arm can lead to serious engine failure, including damage to valves, pistons, and the cylinder head. Symptoms include loud tapping noise from the rocker cover area, loss of power, and rough engine running.
The valve rocker arm transfers motion from the camshaft to the exhaust valves, allowing them to open at the correct moment in the engine cycle.
