What is a timing chain?

A timing chain coordinates the rotation of the crankshaft and camshaft(s) in correct timing and permits the engine’s valves to open and close during each cylinder’s firing. The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance essential as well. A timing chain is in the front of the vehicle and is connected to a set of gears and pulleys that power several mechanical components. For your engine to fire perfectly, the timing chain must effortlessly rotate around the gears without delay. Even though the timing chain is made from metal, it is subject to wear and tear and will in time need replacing as recommended by the manufacturer in their guide. A four-stroke engine will work on a cycle with four strokes within each one:

  • Intake stroke

  • Compression stroke

  • Power stroke

  • Exhaust stroke

The task of your timing chain is to perform the accurate operation of the cycle at the correct time of its strokes. If the pistons and valves don’t move exactly at the right time, then the engine will not work or it can get damaged, leading to costly repairs.

Top warning signs you need to replace your timing chain

The timing chain can start to stretch and wear over time, which will cause the engine's timing to be inaccurate and produce a few warning signs.

  • Engine misfires or runs poorly

  • A sign of a timing chain wearing out is if your garage technician tells you they have found small metal pieces in the oil, as these can break off the chain and find their way into the oil pan.

  • If the engine does not start, or fails when driving, then this can be caused by a broken timing belt. If the belt is broken before you start the engine, then it will not have enough compression to start it at all.

  • Engine light on dashboard can illuminate due to faulty timing belt

  • When the timing chain is loose, it often causes a vibration from within the vehicle and that will produce a rattling sound as the engine idles.

What does a timing chain do?

The timing chain is specifically responsible for connecting the crankshaft and camshaft within the engine, which are in turn, responsible for opening and closing the engine's valves.

How complex is a timing chain repair?

A timing chain needs to be replaced between 40,000 and 100,000 miles and problems are not uncommon, especially for cars with higher mileage on them.

Like every part used to construct a car engine, the timing chain is subject to natural wear and tear which means, eventually, it will need to be replaced. If your engine oil is low, this will speed up the process of degradation for the part as the build-up of heat and friction will damage the part.

Furthermore, there are a variety of parts which are responsible for keeping the timing chain in the correct position including the chain guider, chain tensioner and chain silencer, which are also liable to suffer from wear and tear. If these parts are damaged, the timing chain will invariably become unsafe as well.

What will happen if my timing chain breaks or is damaged?

If the timing chain in your car is damaged or broken, the engine may feel sluggish, be low on power and or completely unable to start. As the timing chain wears down over time it becomes longer as it is stretched. Once this process has taken place, the ignition and valve timing becomes troublesome.

There are also a few signs that other parts surrounding the timing chain are damaged. If you can hear rattling, whirring, whining or buzzing, there is a good chance that the timing chain guide or timing chain tensioner are broken and responsible for the offending noise.

How much does a timing chain replacement cost?

The average price for a timing chain replacement is around £962.91 when booked with WhoCanFixMyCar. The cost of a replacement will depend entirely on the extent of the damage, the age of the car and the model of the car as well.

What can I do to prevent timing chain problems?

Changing your engine oil regularly will give you the best chance of keeping the timing chain in the best health and using premium oil will improve the help even more. In a well maintained engine, a timing chain could last for up to 300,000 miles and above.
