Rocker arms work in conjunction with your camshafts and valves, applying pressure from the camshaft to open and close your intake and exhaust valves. If your rocker arm rollers have failed, this can lead to extreme camshaft damage, requiring the camshaft to be replaced. Replace your rockers whenever servicing your camshafts or replacing your hydraulic lifters to ensure long-term engine reliability.
