Ticking Noise In Engine
Ticking noise in the engine, during the park, or in driving is a common cause for concern for drivers, which may require your serious and immediate attention. To ensure minimum damage to you and your vehicle, follow our detailed guide to engine ticking sound that completely navigates this potentially serious issue. Everything you need to know, from common causes to serious ones and how to tackle them, has been described in detail below.
The most common cause of engine ticking noise is inadequate oil pressure. This is an indication that essential engine components are not getting enough lubrication. It’s possible that the oil level in your engine is low. Alternatively, the low oil pressure could be caused by a malfunction or issue within the engine.
Ticking Noise In Engine: How To Navigate?
Ticking noise in car is extremely evident and if you see your car experiencing the same, break down this noise. Note whether there is a ticking sound in engine while idling or during acceleration. Is the car making the noise even in park? Where is the noise particularly coming from? Note these details and refer to them while you diagnose your car.
Keep in mind that an engine ticking sound is worth your immediate attention. The problem can vary from highly urgent to normal. Let us begin with the most non-worrisome culprits to get them out of the way. In certain models of four-wheelers, the following reasons are no cause for concern. Take a look at this list of normal causes for ticking sound from engine:
Injectors
This is an important part of the engine and is responsible for injecting liquid fuel into the internal-combustion engine. It is even used for providing water to the boiler.
One of the most common reasons for an engine ticking sound continues to be these injectors today. This cause is attributed to their electrically functioning nature which makes a ticking noise in engine. If this sound is increasingly louder, it indicates that you have malfunctioning injectors.
Purge Valve
Another important engine component, the purge valve, is responsible for releasing the gasses in front of the charcoal canister into the engine’s intake, making it a crucial part of the car for even starting.
This is where these transported gasses are then burnt, which facilitates the car to run. As the purge valve works, one can expect a ticking noise in the engine.
PCV Valve
PCV stands for positive crankcase ventilation and ensures that the air and fuel from the crankcase do not escape to the atmosphere but return to the cylinder through the intake manifold. It is considered normal for a ticking noise in the engine as the PCV valve goes about its work and is not cause for worry.
These are highly typical causes for ticking noise in the engine but bear in mind that if the ticking sound that comes from them is continuously loud and constant, it is best advised to check it. Do not self-diagnose your car, and always try to get a professional point of view to be sure.
If you are experiencing a ticking sound in the engine, keep looking for the check engine light, as it is the first visual cue that your car is facing distress.
If you see the light blinking on your dashboard in addition to the engine ticking sound, get your car checked immediately to ensure minimum mechanical and financial damage.

Ticking Sound In Engine While Idling
Let us take a deeper look into the causes of an engine ticking sound that is caused while the car is idling. Before we dive into that, what does an idling car even mean? The state of idling refers to leaving your car’s engine on or running but not in motion.
Ticking noise in the engine is most commonly noticed during this vehicle’s state. The engine ticking sound can be drowned in the traffic, which is why it is incredibly crucial that you are vigilant while in the car.
Following is a detailed list of possible culprits for the same:
Low Level Of Engine Oil
A sufficient amount of engine oil is essential for the proper functioning of your engine as it acts as a lubricant for the moving parts of the engine. It even acts as a cooling medium for your engine.
You can expect excessive wear and tear if your car is driven with low engine oil levels. Overheating of the engine is also a common repercussion of the same. Another common side effect of low engine oil levels is a ticking noise in the engine.
Let us break down this engine ticking sound. As mentioned above, engine oils provide lubrication to engine parts, in the absence of which the metal parts tend to rub against each other roughly, which gives rise to these sounds.
If caused by the said low level of engine oil, this ticking noise in the engine generally comes from the timing chain and the valve train components.
Normal Wear And Tear
One of the most common and obvious causes for an engine ticking sound is the natural aging of the car and the obvious wear and tear that comes with it. As mentioned in the above section, certain parts of the engine, including the injectors, are bound to make a tapping sound as they function.
This sound is more like a pencil tapping sound; anything louder or rougher than that is cause for speculation that something is faulting.
Next in line is the valvetrain, which also makes a small ticking noise in the engine as it works, even in optimal condition. It deals with valves, pushrods, lifters, and camshafts, which wear out with time and produce this sound.
The internal parts of your engine, especially the ones in motion, are subjected to normal wear and tear. As these parts work precisely in short distances, they need to function well to ensure the smooth running of the car.
A ticking sound from the engine can result from time and can be fixed with regular maintenance checks in these cases.
Malfunctioning Reciprocating Parts
Reciprocating components are significant causes of ticking noise in the engine, even more than the commonly suspected rotating components. These parts include pistons, valves, and pushrods.
These parts can get subjected to faults, breaks, and wear out, leading to the engine ticking sound. If so, this is a serious problem, so you should get them looked at immediately and check if they are malfunctioning. We have discussed common subproblems that cause this ticking noise in the engine below:
Bad Pistons
Pistons are an indispensable part of the engine and a significant part of your car’s functioning. It is one of those components that allow your car to move forward.
It is responsible for converting fuel into energy and driving the car in the desired direction. They are also more prone to malfunctioning and damage and show the same through ticking noise in the engine.
If left unchecked, this can lead to a much bigger problem, so if you hear this engine ticking sound, rush to a mechanic before the damage worsens.
Bad Pushrods
This, like the piston, is also a part of the internal combustion system of the car and is integral to its general functioning. They also reciprocate parts that give rise to a ticking noise from the engine if it malfunctions.
A fault pushrod is generally bent and is caused due to excessive acceleration. This is yet another serious issue for the car, which is indicated by a ticking sound in engine while idling. The best way to tackle this is to replace it immediately.
Unadjusted Valves
If your car has an unadjusted valve train, you will hear a ticking noise in the engine. It is one of the most common reasons for the same. To understand why, let us look at the mechanism that causes it. The valves open and close every time your engine spins twice around.
In the case of a single-cam engine, the cam actuates the pushrods, which then open the valves through a lever. The latter part is called a rocker’s arm.
It is slightly different from an overhead cam engine, where the valves are depressed by the camshaft lobes. The engine ticking sound is caused when the distance from the valve to the cam or pushrod is improper. This can be caused by faulty shims and adjustments that keep the distance between the valve and pushrod or cam at its optimal level.
When these components shift around, it leads to a ticking sound in the engine while idling. This can be fixed by getting new shims or fixing the rocker’s arms.
Rod Knock
Before we get into the ticking noise in the engine caused by the rod knock, let us first understand this critical component of the engine. The good thing is that problems with rock knock are sporadic as they are scarce. The ticking sound in engine while idling caused by rod knock is easy to identify as it sounds like pretty heavy knocking.
The rods which are moved by the pistons rotate the crankshaft. These rods have some bearing attached to them to ensure steady movement. With time, these bearings are bound to wear out, which then causes the rods to knock around.
This will then cause ticking noise in the engine. This does not change the engine’s temperature, but you will experience a slowdown in your RPM, affecting your acceleration.
These bearings are hard to locate, and sometimes the engine must be torn down to get to them. The best way to tackle this problem is to replace the engine altogether, which is an expensive solution to this!
Lose Spark Plugs
Like the name suggests, spark plugs cause the sparks of electricity that ignite the combustion, which even lets your car start. Like the valves, even malfunctioning spark plugs that are not aligned can cause fires. The ticking noise in the engine can be a result of loose and incorrectly attached spark plugs.
How can you figure out that the ticking noise from the engine is coming from loose or faulty spark plugs?
Spark plugs are a crucial part of your vehicle as they are the components that seal the combustion cylinders. If not, there will be a leak, leading to a ticking noise in the engine.
Such faulty spark plugs can tend to strip the cylinder head threads, which then do not allow the containment of the cylinder pressure, further degrading the car’s overall performance.
How to know that the ticking sound from engine is coming from faulty spark plugs? You can start with a simple visual inspection. It is imperative to note that this inspection should only be conducted when the car is not on. If you notice cracks on your spark plugs, it clearly indicates that it needs replacement.
Make sure that all the connections are tight. You can do this yourself at home. Ensure you do not touch the engine while it’s hot or with your bare hands. Use a tutorial or the car’s manual while doing the same.

Malfunctioning Loose Engine Fan
Ticking noise in the engine can result from faulty or loose engine fans! If you hear said engine ticking sound or tapping noise coming from the hood, you should suspect your engine fan! It is easy to figure it out visually.
Look at the engine fan and see the clips and bolts to determine if any part is loose or broken. Figuring out worn-out parts is easy as it is most visible.
If there is any contact of the fan’s blade with the other components, including but not limited to the shroud, cables, and belts. Take this time to tighten all bolts and clips. Replace and repair any damaged parts. Ensure you do not do this when the blades are in motion.
Fuel Injectors
The injector valves open and close quickly to let in the required fuel for combustion. Due to this reason, an engine ticking sound from it is natural. Not all cars make this noise, so it is best to talk to your dealership to ensure that your car is not undergoing significant stress. If you find that it is not supposed to create any ticking noise in the engine, replace them as soon as possible!
Exhaust Manifold Leak
Your vehicle’s exhaust system is mainly used for throwing out combusted fuel properly and systematically. We see a part of the exhaust system every day, i.e., the exhaust pipes at the vehicle’s rear end, but that is not all it is.
The system also includes other pipes, sensors, and mufflers, which can develop leaks with general wear and tear or by impact and can develop a ticking noise in the engine. This is a severe problem and should be tended to immediately.
This ticking sound from the engine may not seem like a big deal, but if caused by exhaust issues can lead to severe repercussions. Due to combustion, there are bound to be toxic fumes that need to be released.
A ticking noise in the engine coming from the exhaust system is also an indication that your fuel consumption has increased.
Lifters
A ticking sound in engine while idling can also be due to the lifters in your engine. In the case of the hydraulic valve lifter, there is a small cylinder on the vehicle’s hydraulic valve by the rocker’s arm. Here, we can hear the lifter tick, which, as the name suggests, is a continuous ticking noise in the engine.
Even though this issue can arise with any car, it is most common in older vehicles. It is also seen in hydraulic lifters. They are most prone to this issue.
This ticking sound from the engine that occurs due to lifters is because of the oil. It is also because of the normal wear and tears. Replacement is the way to go. Any other fix is not going to last for the long run.
Ticking Noise In Engine: How to Fix It?
The first step to fix an engine ticking sound is to figure out its cause. The solution to this problem is going to depend on the problem. For instance, spark plugs that are not installed properly are easier to fix.
As it will just take a reinstallation, you will have fixed the problem. As described in the above section, most problems will need the faulty component replaced.
There are other ways to go about the same, but all of them will be temporary solutions. The only way to completely get rid of the ticking sound in the engine while idling is to get the components replaced.
There are other things you can do to fix this engine ticking sound. You should begin by topping up the engine oil or replacing it fully. Oil is a significant part and contributor to the smooth functioning of the engine. It works as a lubricant for the internal components.
Try to figure out where the ticking noise in the engine is coming from. If you can find out that the sound is coming from the bottom of the engine. If so, you have a good reason to suspect the crankshaft bearing. You may even need to remove the oil pan.
Ticking Noise In Engine: Why You Should Not Ignore it?
An engine ticking sound is just an indicator of potentially significant problems in the engine. It can be the beginning of an engine failure or even leaks of toxic gas.
Ticking sounds may seem ordinary, but they are not. Do not take them lightly and get into it! Most of these are caused due to gradual wear and tear and, if left unattended, will lead to the breaking down of your car.
Ticking Noise In Engine: Checking The engine
As mentioned above, the engine ticking sound, if heard, should be checked immediately. You can do it yourself if you are handy with your car and tools. Make sure that the car engine isn’t on. Also, give it time to cool off before working on it.
Keep gloves on the entire session. Remember that touching the engine parts with your bare hands can lead to injuries. Always keep your car manual beside you.
If you aren’t sure if you can do it, get your local mechanic to look at it. Do not play with your engine if you are unsure about what you are going to do or do not have confidence in your abilities. It can damage your vehicle more seriously and even cash you a bigger check.
Ticking Noise In Engine: Costs Involved
The first thing that comes to mind when discovering any issue with one’s vehicle is the cost of repairs. It is no surprise to anyone that automobile repairs are not cheap. They range from affordable to extremely expensive. This cost depends on a few contributing factors.
The first and most obvious one is the issue that your car is facing. In the above sections, we have discussed a skew of possible problems that your vehicle may be experiencing, giving rise to this engine ticking sound.
The level of damage to the vehicle is an obvious contributing factor to the final price. We have discussed two groups of reasons which can be responsible for the engine’s ticking noise: things considered normal and the other serious issues that need immediate attention.
