Rocker Arm Spring
Volvo

The rocker arm spring is an integral part of the valve train, providing the necessary tension to keep the rocker arm in contact with the valve and camshaft. Its proper function ensures precise valve timing and smooth engine operation. A high-quality spring resists fatigue and maintains consistent tension over time, which is vital for engine reliability and performance. Worn or weak springs can cause misfires, rough idling, or valve train noise, leading to potential engine damage. Regular inspection and replacement of these springs help maintain optimal valve operation.
