![]() ![]() ![]() If the timing chain brakes, pistons will hit the valves and damage the engine which causes expensive engine rebuilds. So, it’s one of the key components in your car’s mechanical system. It ensures that the engine’s pistons don’t hit the valves which would cause your engine to stall. It connects the crankshaft and camshaft, therefore opening the valves and controlling the pistons in a precise manner.īecause of the is chain, everything runs smoothly within an engine’s firing cycle. Your car’s timing chain is a metal chain mounted in the engine which rotates between the gears in the engine to move some of the crucial mechanical components. What’s a timing chain and what does it do? It’s always useful to know how a damaged timing chain will affect your engine’s functionality, so our team decided to give you a detailed overview of the greatest signs. ![]() So, it’s crucial to respond after hearing the first timing chain symptoms telling you it’s time to change your chain. The metal chain serves a key role in opening your engine’s valves on time, and its dynamic role in the engine makes it vulnerable. When a timing chain becomes stretched it will cause vibrations inside the engine that will produce a rattling sound as it idles.Technological advancements in the automotive industry enabled car manufacturers to replace rubbery timing belts with more sophisticated timing chains. A normal engine should have a consistent and smooth sound indicating that everything is running as it should. One auditory way to find out if your timing belt is failing is to listen for unusual rattling noises. If its sensors detect something is wrong then the light will turn on requiring immediate attention and a scan to be conducted to get to the root of the problem.Ībnormal rattling sounds from the engine while idling The vehicle’s computer will display this warning light only if it detects something is wrong with the car. The check engine light is onAnother indicator of a stretched or a damaged timing chain is the check engine light. If this happens your engine may skip its timing and the pistons may come in contact with the valves leading to a serious repair and impairing the movement of your vehicle. The engine refuses to start or fails to idle A broken or damaged timing chain will not allow the engine to start or will have it fail while driving. However, it could also be a sign of something else, so keep that in mind when inspecting the oil. If there are metal shavings found in the oil it could be an indication that the timing chain has been stretched and is on its way out. Metal shavings are found in the oilA good way to detect if a chain is failing is by looking at the oil in the engine via an oil change. The engine misfires or runs poorlyThis could indicate that the timing is off with the engine as the valves aren’t properly in sync with one another and could leave a small gap in between the combustion process. Here is a quick list of signs to look out for which indicate that it could be time to replace a timing chain. It’s also harder to make a timing chain jump teeth causing the engine to go out of sync. It is important to note that while a timing chain is more durable than a timing belt signs of it stretching or failing are slightly harder to detect. It is also important to keep the timing chain well lubricated as using the wrong viscosity oil could damage the timing chain pins and plates. However, this will still depend on the engine and the specifications of the manufacturer. ![]() As this part lasts longer than a timing belt these will be changed between the 120,000 to 150,000-kilometer mark of a vehicle. ![]()
