One of the more fun aspects of driving a car is the force and sounds you experience when you accelerate. When all is going well, you can feel the power of the engine under the hood and hear it roar as you step on the gas. However, for some drivers, there is an unwelcome noise that comes along with it – a clicking noise when accelerating.
While this clicking noise may seem like a minor issue, it can actually be a sign of something more serious. In most cases, the clicking noise is caused by something wrong with the car’s acceleration system particularly relating to the engine’s fuel and air mixture combustion procedure.
The components that are responsible for this noise are the valves, the pistons, and the crankshaft. When these parts don’t work correctly, they can create a clicking sound that you’ll hear when accelerating. In this article, we’ll take a closer look at what’s causing the clicking noise and how they come about to be.
Is Ticking Noise When Accelerating Normal?
There are multiple sounds such as roaring, humming, and hissing that your car can make that can consider normal in an engine, but what about a clicking noise? Many drivers who have reported hearing this specific sound when accelerating their car worry that it may be a sign of engine trouble.
This noise is usually just caused by something minor and isn’t anything to worry about if it just lasts for an odd second or a few. However, if the clicking noise persists or becomes louder, it’s best to take your car to a mechanic to have it inspected just to be safe.
There could be something wrong with the engine that needs attention, and ignoring this noise could lead to even bigger problems down the road. So, let’s jump into it and take a closer look at what might be causing your car to make this clicking sound when you step on the gas!
5 Reasons Why Clicking Noise When Accelerating
There are multiple potential reasons why your car might be making a clicking noise when accelerating. The following are some of the most common explanations:
1. Bad Reciprocating Components
A more serious issue that could be causing your clicking noise is faulty reciprocating components. This means that something such as the piston, connecting rod, or crankshaft and relevant valves are not functioning properly. When these components come in contact with each other, they can create a clicking noise if they’re not working correctly as intended.
2. Low Amount of Engine Oil
When your engine oil level is low, it can cause the engine to make strange noises. One of these sounds could be a clicking noise, specifically. Engine oil is supposed to act as a lubricant for all of the internal engine components, and if there’s not enough of it, they can start to grind against each other and create that clicking noise.

3. Rod Knocking
The rod knocking phenomenon is often mistaken for a clicking noise. This sound is actually created when the bearing of the connecting rod knocks against the engine block as the piston moves up and down. This bearing is supposed to be lubricated by the engine oil, but if there’s not enough of it or it’s dirty, this noise will occur especially with the more wear and tear on the engine it encounters over time.
4. Fuel Injectors Firing
Fuel injectors can also cause a clicking noise when they fire. This usually only happens when the engine is first started up, and it’s just the injectors doing their job of delivering fuel to the engine while it warms up. In some cases, the clicking noise persists even after the engine has fully warmed up, but it might be worth having a mechanic take a listen to see if this is a cause for concern.

5. Valves Not Adjusted
Service and maintenance of your car require that various engine valves are periodically adjusted. If these valves are out of adjustment, it can cause the engine to make a clicking noise. This noise is usually more pronounced when the engine is under a heavy load, such as when you’re accelerating.
The valves work by regulating the flow of air and fuel into and out of the engine, so if they’re not adjusted correctly and there is something called a rocker arm that is responsible for opening and closing the valves. The camshaft has a pushrod that controls the rocker arm and must be precisely positioned from the valve.
This is especially true since the valves change position so quickly and at such a short distance. If the settings aren’t precise, the components will shift about, producing ticking or clicking noises.

FAQ
How do I fix a rattling noise when I accelerate?
To fix the rattling noise, you need to determine the root cause. There are many reasons why this noise can occur, so it’s best to take the vehicle to a mechanic for inspection. Some of the most common causes include bad reciprocating components.
However, it will still need further investigation to determine the specific issue but generally, this is due to simpler components such as broken or loose heat shields or engine mounts.
Why does my transmission slip when I accelerate?
A major cause of transmission slippage is low, worn-out, or burned transmission fluid. Other reasons behind this may also include, solenoid problems, cutch problems, worn-out gears, torque converter issues. Most issues related to transmission are not cheap to fix, so it is best to take the car in for service as soon as possible before the problem worsens.

Why is my car revving high when accelerating?
Some common reasons for a car to rev high when accelerating are incorrect spark plugs, ignition coil problems, vacuum leaks, and low compression. If the problem is not fixed, it can lead to extensive engine damage. It is best to take the car in for service or consult with a mechanic to determine the source of the issue.
Conclusion
In summary, there are many potential reasons why your car might make a clicking noise when you accelerate. Some of the more common causes include bad reciprocating components, low engine oil, dirty engine oil, fuel injectors firing, and valves that are not adjusted correctly.
If not addressed in due time, these issues can lead to more expensive repairs. It is best to consult with a mechanic to determine the specific cause of the clicking noise and take appropriate measures to fix it. Thanks for reading!
