The camshaft assembly is a core component of the engine's valvetrain, responsible for opening and closing the intake and exhaust valves at precisely the right moment in each combustion cycle. It works in direct synchronization with the crankshaft, and any wear to the cam lobes or bearing journals will disrupt valve timing — leading to loss of power, rough running, increased fuel consumption, or difficulty starting. Replacing a worn camshaft assembly promptly restores correct engine breathing and protects the surrounding valvetrain components from accelerated damage.
