The timing chain is a crucial component in an internal combustion engine, connecting the crankshaft and camshaft to ensure that the engine's valves open and close at the correct times during each cylinder's intake and exhaust strokes. Unlike a timing belt, a timing chain is made of metal and is designed to last longer, often exceeding the engine's lifespan. Regular maintenance is essential, as a worn or stretched timing chain can lead to significant engine damage. It's important for vehicle owners to pay attention to any unusual noises or performance issues, as these can indicate a timing chain problem that needs immediate attention.
