Timing Chains

Unlike belts, the metal timing chains sit inside the engine, but much like timing belts they allow the camshaft and crankshaft to rotate in unison. This acts as means of opening and closing the engine’s inlet and outlet valves at the right time. It achieves this via a tensioner pulley and guide rail system. The timing chain will suffer wear and tear with age and constant use. As a result, experts recommend replacing yours every 40,000 to 100,000 miles. Stretching is the most common issue affecting worn timing chains. This will slow down ignition times and harm your engine’s performance.
