What Is a Timing Chain and Why Does It Matter?
The timing chain synchronises the rotation of your engine’s camshaft and crankshaft, ensuring valves open and close at the correct intervals. Unlike timing belts, chains are built to last—but they’re not immune to wear, especially in high-mileage or poorly maintained engines.
A worn or stretched timing chain can throw your engine’s timing off, leading to:
- Rattling or ticking noises from the engine
- Loss of power or misfires
- Check Engine Light warnings
- Difficulty starting
- Metal shavings in the oil (a sign of internal damage)
