Why Is My Jeep Making A Ticking Noise?
So, what’s that engine-ticking noise in your Jeep?
If your Jeep is making a ticking noise, there’s likely oil clogging the valvetrain, which causes friction and noise with the lifters and drivetrain. This problem will solve itself in a few hundred miles, but your Jeep may also be ticking because the wrong air filter is being used or the oil pump is dying out.
While the first issue can potentially be diagnosed and fixed by the Jeep’s owner easily, mechanical defects like the second two issues are more difficult to diagnose and fix unless the driver is a mechanic.
In this article, you will be given in-depth explanations of the issues that can lead to a Jeep ticking noise and how to fix it.
Jeep Ticking Noise Causes
1. Valvetrain Problems
If you have noticed a ticking noise in your Jeep, you should first investigate the vehicle’s valvetrain.
By design, most cars use hydraulic valve lifters. These rely on oil pressure to help maintain a tight clearance between the camshaft and the rocker arm.
If the pressure is not correct, it can cause problems between the lifters and the drivetrain, thus starting the tapping noise that becomes a concern. A Jeep lifter tick, tick, ticking may be annoying, but it’s not dangerous.
To rectify this issue, use cold oil at start-up to help pump up the lifters. If that solves the problem, then it likely means the temperature of the oil is the culprit.
However, using oil at ordinary temperatures could result in the viscosity being too thin to work the lifters efficiently.
The oil usually breaks down after over a thousand miles, eliminating the noise. However, if that doesn’t happen, it could signal a bigger vehicle problem.

Jeep Valvetrain Maintenance
As with any vehicle, it is a good idea to care for the parts that keep it moving.
It has already been established that the valvetrain can do strange things when not cared for properly. So, taking care of your Jeep’s valvetrain is important!
Some tips for caring for your Jeep’s valvetrain include:
- Some models of Jeeps require the valvetrain to be cleaned periodically. If your engine light won’t go off, you may not be cleaning your valvetrain often enough.
- The camshaft is usually the part of the valvetrain that fails first, but, if the other parts have not been cleaned correctly, the issues can spread. This means that the longer the issue is left unattended, the more money it will cost to fix.
- Only use the oil recommended for your specific engine. Using the wrong oil can result in many things going wrong with the vehicle.
2. Mechanical Issues
Mechanical issues are notoriously harder to diagnose because they usually involve popping the hood and examining the vehicle’s inner workings. Below are two of the most common mechanical causes of a ticking noise in your Jeep.
The Wrong Air Filter is Being Used in the Vehicle
Using the wrong type of air filter in a vehicle is a significant cause for concern and could explain the ticking noise. So, the first thing you should do when you open your hood is check if the correct filter is being used.
Even if the specifications of the air filter are correct, vehicles work much better with the filter supplied by their manufacturer in many cases.
Even if the manufacturer filters are more expensive, it is recommended to pay the extra for peace of mind of knowing the chance of issues will be slimmer.
Additionally, paying a bit more for your air filter could also potentially save you money by preventing further mechanical issues that need to be fixed.
How to Change the Air Filter in a Jeep
Some people prefer to make improvements to their cars without the need for a mechanic. An air filter is easy enough to change if the correct directions are followed.
To change your air filter yourself, follow these steps:
- Undo both hood catches and prop up the hood.
- Turn attention to the factory air box on the lower left side of the engine bay and find the four clips around the airbox. Undo each clip.
- Use a 10mm socket wrench and undo the two bolts to the right of the airbox.
- Lift the airbox to reveal the filter.
- Pull out the filter and find the replacement.
- Replace the filter, while ensuring the tapered end always points towards the driver’s side.
- Once in place, close the box again, replacing all the screws.

Air Filters to Consider for Your Jeep
If changing your Jeep’s air filter is the best course of action, then the following choices are great filters to consider for your vehicle.
Spearhead Max Thrust Performance Filter
The Spearhead Max Thrust filter comes recommended by Amazon thanks to the rave reviews from people who have actually used it, as well as the high quality of the product. It is listed as an Amazon’s Choice product.
The Fram CA348 is another product gathering excellent reviews on Amazon, with many liking how robust it is and the filter’s longevity.
Amazon also has this one listed as an Amazon’s Choice product, meaning it is another product of great value.
K&N Engine Air Filter
The K&N product comes at a higher price than the other two, but it comes with many benefits to back up the price.
It comes pre-oiled, so it is a plug-and-play component you can easily add. This filter also lasts 50,000 miles without cleaning. [Filter Reviews]
Faulty Oil Pump
The worst-case scenario when a clicking noise arises is the oil pump slowly dying out. Driving a car with a dying oil pump can slowly damage other components of the vehicle, meaning that the cost associated with a repair could be much higher if the driver continues to use the car.
If you have checked your jeep’s valvetrain and air filter and are still hearing the ticking sound in your vehicle, then you should bring it to a mechanic as soon as possible.
Why Should Jeep Ticking Noises Be Taken Seriously?
Many issues can arise with Jeeps. Some problems are worse than others, but drivers must remember that driving a problematic vehicle could be putting everyone inside and other drivers at risk.
That’s why it is always imperative to take any vehicle-related issues seriously.
If this is your Jeep’s first issue, it would be wise to check the warranty and contact the manufacturer. If the Jeep warranty is still valid, it could save you money. Contacting a mechanic would be the best action if the vehicle warranty expires.

Addressing Jeep Ticking Noise
Jeep owners may experience a ticking noise in their vehicle at some point in time. Various factors, including wear and tear, damaged parts, excessive wear, and more can cause this noise. It is essential to address the issue promptly to prevent further damage to the vehicle.
One possible cause of the ticking noise is a faulty purge solenoid. The purge solenoid is responsible for controlling the flow of fuel vapors from the charcoal canister to the engine.
If the solenoid is damaged, it can cause a ticking noise in the vehicle.
Another possible cause of ticking noise is contaminated fuel injectors.
Fuel injectors can become clogged with debris and other contaminants, causing them to malfunction and create a ticking noise. It is important to have the injectors cleaned or replaced to resolve the issue.
The timing chain is another component that can cause ticking noise in a Jeep. The timing chain is responsible for opening and closing the engine’s cylinders.
If the chain is worn or damaged, it can lead to a ticking noise in the vehicle. Replacing the timing chain can resolve the issue.
The crankshaft is also a component that can cause a ticking noise in a Jeep. The crankshaft is responsible for converting the up and down motion of the pistons into rotational motion.
If the crankshaft is damaged or worn, it can cause a ticking noise in the vehicle. Replacing the crankshaft can resolve the issue.
Addressing Jeep ticking noise requires proper diagnosis and timely repair. It is essential to identify the root cause of the issue and take appropriate measures to resolve it.
