The most common signs of a faulty timing chain are engine misfires, metal shavings in the oil, and rattling noises from the engine while idling. Since the inception of the internal combustion engine, one constant has remained – all of them have a timing chain or timing belt. Most higher-displacement engines have a timing chain as opposed to a timing belt. The chain is located in the front of the motor and is attached to a set of gears and pulleys that power multiple mechanical components, including the crankshaft and camshaft. In order for your engine to fire, the timing chain must smoothly rotate around the gears without hesitation. Although the timing chain is made out of metal, it is subject to wear and tear and may break if not replaced as recommended by the manufacturer.

Why It’s Important and How to Tell Which One Your Car Has Timing belts and timing chains do the same thing: They connect the engine’s crankshaft to the camshaft, which opens up the valves of the engine. The valves let fuel and air into the engine, and exhaust out. However, timing chains and timing belts are made of different materials (metal and rubber, respectively), installed in different ways, and have different maintenance costs (the most important characteristic for car owners). We’ll explore what these car parts do, how they differ, and how much they cost. What Do Timing Belts and Timing Chains Do?
