Timing Belts and Signs of Failing

Timing chains are metallic components of the car that connect the camshaft to the crankshaft. These components are major parts of the engine that contribute to the revolutions of the pistons. Without their functionality, a combustion engine will be unable to work.

The crankshaft and the camshaft have spikes or teeth for the timing chain. When the timing chain attaches to the crankshaft, and the camshaft, it dictates both of their movements, so that they can rotate with accuracy and bring about the mechanical workings of an engine.

A timing chain is a solid, durable metal that lasts the lifetime of the car. However, for it to last forever, the car owner has to be on top of their engine oil replacements. If that is not the case, then the car will show signs of a damaged timing chain. Below are a few indications of a failing timing chain.

Timing belts and Rattling Noise from the Engine

If you are driving the car at idle or low speeds, and you notice a rattling sound coming from the engine, this can be the rubbing of the damaged chain against the engine. You are most likely to notice this sound during the ignition of the engine.

Like rubber timing belts, a timing chain can also stretch over time, and in this occurrence, it fails to attach tightly to the camshaft and crankshaft. This ultimately results in some parts of the chain touching the outside covers and makes a noticeable rattling noise.

Due to the natural wear and tear, it fails to apply adequate tension to the timing guide. To confirm this issue, make sure to remove the timing chain cover, if you find metal shavings inside the timing chain cover, this indicates that the timing chain is overstretched.

Timing belts and Issues

When the timing chain starts to wear off, it begins to jump teeth on the crankshaft. This disrupts the timing of the pistons, making the valves open and close inaccurately. This will likely decrease the car’s engine power, and you will not get the best acceleration after you push the throttle.

Timing-related codes are unusual, and the crankshaft and camshaft codes do not have clear indications in the car. Therefore, an extension of the timing chain can result in a check engine light that does not go away until you replace the belt. If your check engine light keeps blinking and you have tried everything to make it stop, then it is time you also open up the timing belts and analyze them.

These are the most notable and common indications of a timing belt or chain replacement. Even though they last forever in most cases, if you feel your car is low on maintenance, and you find these signs then take your car to a specialist for a timing chain or timing belt replacement.
