Illuminated Check Engine Light

When the vehicles systems detect an irregularity in the performance of the engine, the check engine light comes on. A failing rocker arm could affect how the engine runs and trigger the check engine light.

Poor Engine Performance

Since the rocker arms are what transfer the movement of the camshaft to the valves, any problem with the rocker arms could affect the engines intake and exhaust. If the valve timing or the air-fuel ratio in the cylinder are off, the engine might generate less power. This could result in poor acceleration or stalling.

Rocker Arm Noise

When there are any issues involving the valves, these could make rapid clicking, tapping, or ticking noises. With broken or poorly lubricated rocker arms, the valves might not be able to open and close properly.
