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 timing belts, timing chains are made of metal and are designed to last the lifetime of the engine, reducing the need for frequent replacements. However, they can still wear out or stretch over time, leading to potential engine damage if not monitored. Regular maintenance and inspections can help detect issues early, ensuring optimal engine performance and longevity.
