Common reasons for engine ticking noises

Drivers who can hear a ticking sound coming from the engine of their vehicle should stop the car as soon as possible and address the issue.

Common reasons why they can hear these sounds include;

• Insufficient engine oil or poor lubrication leading to low pressure
• Leaking exhaust system
• Faulty fuel injector
• Worn or damaged fan belt
• Loose or damaged spark plugs

If the ticking noise persists after performing basic checks and maintenance, or if you notice other symptoms like decreased performance, poor fuel economy, or warning lights on the dashboard, it’s important to have a professional mechanic diagnose and repair the issue.

Ignoring a ticking sound can lead to more serious engine damage over time – so get it looked at as soon as possible.

How to fix a ticking noise

If you think you can fix the issue yourself before taking it to a garage to be checked, here are some steps you can take to stop the ticking sound in the engine.

The first step is to check you have are your fluids and lubricants at the correct levels and they are clear of dirt and debris.

Clear anything that is clogging up the various systems and replace any worn components.

If there is an issue with the exhaust system, take it to a mechanic as this will likely involve more extensive work.

This is also the same for the fuel injector as it involves specialist equipment to replace.

Regarding the fan belt, you can see this by opening the bonnet. If it is worn or damaged, it will need to be replaced as soon as possible.

Loose or damaged spark plugs can cause a ticking sound, so if you can still hear the ticking after cleaning, lubricating or replacing them, there could be a more serious problem.

If you are looking at the status of the spark plugs, it is worth also checking the glow plugs at the same time.

Ticking noise from the engine

In some cases, ticking noises can be a normal engine sound – however, when it becomes louder and increasingly regular you will likely have a serious problem.

Also, if the ticking sound is accompanied by a jerking engine or even smoke pouring out – stop the vehicle immediately.

There are many causes for a ticking noise, regular maintenance and a car service will prevent a lot of these issues from happening.

Engine ticking while car is idle

If your car is idle, it will be easier to hear louder and irregular sounds coming from the engine.

While idle, the ticking sound could be caused by insufficient engine oil or poor lubrication. This can lead to low pressure within the engine.

Leaking exhaust system will lead to further issues, including a ticking engine.

In internal combustion engines, faulty fuel injectors, fan bets and spark plugs can all be heard ticking while the car is idle.

Engine ticking while accelerating

While you are driving, it can be hard to hear a quiet ticking sound coming from the engine – so if you are hearing something irregular coming from under the bonnet it is important to stop the vehicle as quickly and as safely as possible.

This could indicate a serious problem, and something that should be looked at by a trusted local garage or mobile mechanic.
