A Volkswagen timing chain is located at the front portion of the engine. The chain works together with the engine’s camshaft and crankshaft to maintain the motion of the piston and valve. As an integral part of your engine, the timing chain synchronizes the engine’s timing. It ensures that the camshaft can accurately control the opening and closing process of the intake and exhaust valves.
The timing chain and timing belt share similarities in their functions. They both ensure the accuracy of the camshaft. Differences, however, arise in the materials used in making both components. While the timing belt is primarily made from rubber, the timing chain is made from metal. From the durability of these materials, it is understandable why the timing belt is more susceptible to sudden breakage.
The timing chain is crucial in enhancing your engine performance. It operates as a link between the camshaft and the crankshaft. This way, it transmits the motion of the crankshaft to the camshaft. It also precisely conveys energy from the crankshaft to the camshaft by wrapping around the mounted gears used to grip the shafts. Subsequently, there is a reduction in the rotation speed, causing the camshaft to rotate at half the speed of the crankshaft.
Why do you have to change the timing chain?
A timing chain elongates over time due to the constant tensile load placed on it. This wear may cause rattling and whipping noises, and in the worst case, your timing chain will jump, causing your engine to encounter a slow start and sluggish performance. When you notice these symptoms, the replacement of your timing chain will become necessary.
It should be noted that friction is the primary reason for a worn timing chain. This friction cannot be avoided entirely, even with optimal lubrication. This will naturally need replacement over time.
When To Replace Your Timing Chain
Depending on the engine and car manufacturer, timing chains are usually installed as single roller chains or duplex chains and differ significantly in durability and wear. In the absence of any problem with the timing chain, the chain should be replaced between 80,000 and 120,000 miles.
Some symptoms you may notice indicative of a faulty timing chain include:
- A loud bang and no reaction from the engine: This indicates that your timing chain may be broken. Try not to drive your Volkswagen further and contact your nearest automobile repair center.
- Rattling and knocking noises: These noises can be present where the add-on part of your timing chain, such as the pulley, is broken. It is advisable to get it checked quickly to avoid any consequential damage.
- Rattling and clacking noises in connection with engine control light: This noise isn’t a good sign. In most cases, it may indicate that your engine timing chain is probably elongated. You should visit a Volkswagen service center immediately to have the issue examined for proper diagnosis.
- Engine Misfiring: An effective timing chain must always run tightly. When the timing chain loosens, it causes an imbalance in the timing of the engine’s valve and piston, disrupting the combustion process. This causes the engine to misfire.
When you notice any of the symptoms discussed above, you should visit an expert to help you examine the problem for proper diagnosis.
