What causes noisy valve lifters?
A ticking lifter is usually an indication there is a problem with your oil, especially as your car ages. It's possible the lifters themselves are simply worn. If you have a much older car you've been driving for a long time, it is more likely this is the problem.

Will thicker oil stop lifter noise?
Adding more oil will make the noise go away, but it won't solve the underlying cause of the noisy engine – the oil leak.
Does hydraulic lifter treatment work?
Conclusion: lifter treatment might help to clean dirty and sticky lifters and dilute the oil to make it flow easier but be carful with the viscosity, don't leave in the engine till next oil change, and for treatment of less than a 4 litres of oil use only half of the bottle.
What Is A Hydraulic Lifter And How Does It Work
First, let's figure out what a lifter is to determine a more efficient lifter noise fix. Not everyone knows about valve lifters; for one, it's a kind of mechanism in most cars' internal combustion units.
What Causes Valve Lifters To Be Noisy?
Before we get into more details of how to fix lifter tick or that disturbing noise in your vehicle, let's discover what causes the unwanted sound. Here are some of them:
Knowing How To Fix Noisy Valve Lifters
The valvetrain is another possible culprit for the engine ticking problem. It is something you should be aware of when figuring out how to fix lifter tick. Initially installed hydraulic lifters require necessary adjustments for a fully operational plunger in its mid-range of travel.
Frequently Asked Questions
Part of the fix is getting a replacement when essential, and doing so comes at a cost. How much you'd spend depends on the engine you have. In such cases where it's necessary to replace all filters, you can expect that it could be anywhere between $200 to $400.
Final Thoughts
In summary, we hope you will find this article helpful in identifying possible engine problems that cause unwanted sounds. Now that you've learned how to fix noisy valve lifters, you at least have an advantage by knowing ways of further improving your car's performance.
Why does my valve lifter make a noise?
It is easiest to hear while the motor is idling. The tapping noise will speed up when you increase engine RPM because the cylinder is firing more rapidly.
What is a valve lifter?
Valve lifters are finger-sized cylindrical parts (usually hydraulic) responsible for transmitting camshaft movements to the pushrods allowing valves to open and close as required. Which lets fuel into the cylinder and exhaust out of the cylinder. Nothing important.
Why do hydraulic lifters have holes?
Hydraulic lifters have a small hole in the cylinder body to allow oil inside the unit. Oil is virtually non-compressible, so it is perfect for hydraulics. Dirt in the oil–usually caused by poor maintenance–restricts the free flow of oil. It can even clog the lifter hole. Without enough oil in the lifter, you will hear metal on metal tapping–especially on start-up. Get the motor hot, drain the existing oil, fill the motor with new oil, and take it for a drive. Quite often magic occurs, and the tapping will have disappeared.
What is the space between a solid lifter and a rocker arm?
Solid Lifters. Solid lifters have a small space between them and the rocker arm–around 10/1000th of an inch. (The space is necessary to prevent motor parts from binding as they expand as the motor heats up.) This gap is known as valve lash, which when not adjusted properly, leads to lifter noise.
How long do hydraulic lifters last?
Hydraulic, self-adjusting lifters should last well over 100,000 miles. Mechanical, or solid, lifters need to be adjusted about every 30,000 miles–or sooner if they are making noise. These adjustments are needed because of wear in the valve train.
How to prevent a gasket from leaking?
Make sure to follow the instructions. One way to avoid the leaking problem is to use a double oil change to flush the engine.
Where are the lifters on a Dodge Caravan?
Here is one for a Dodge Caravan. The job is relatively simple because the lifters are at the top of the motor under the valve covers. Many other lifters are down inside the motor–like my Hemi–which involves not only removing the valve covers, but the intake manifold, and virtually all accessories on top of the motor.
What Are Car Lifters?
A car lifter refers to your car’s hydraulic valve lifter. It’s a small cylinder attached to your car’s hydraulic valve by a rod called a rocker arm. The system works well, except when it doesn’t. A phenomenon can occur called lifter tick, where the lifter itself makes an irritating ticking or tapping noise.
Why Do Car Lifters Make Noise?
Certain solid and mechanical lifters do not tend to make noise, but your car probably has hydraulic valve lifters, which can fall victim to this type of problem. But why? A ticking lifter is usually an indication there is a problem with your oil, especially as your car ages.
How Can You Quiet Your Car Engine?
Once you verify the lifter ticking is not caused by a worn-out lifter or some other damaged part, the best thing to do is change the oil. Get rid of all the oil currently in the engine and flush it out before adding new oil. Make very sure the new oil you are putting in is exactly the type of oil the manufacturer specifies.
Choose Rislone for Your Needs
In addition to putting in new oil, there are proven additives you can add to your oil to improve performance and quiet your lifters and engines. High-quality products such as our legendary Rislone Engine Treatment serve this purpose and can significantly quiet noisy engines.
Why is my hydraulic lifter so loud?
Hydraulic lifter noise can also be aggravated by excessive valvespring pressure. The Dart heads on our small-block use 1.250-inch-diameter single springs with 110 pounds of seat load and around 280 pounds over the nose. This seat pressure is about 20 to 30 pounds higher than production springs and could contribute to noisy lifters.
Can you clean a check ball?
Sometimes, the caged check ball can be cleaned with a shot of carb cleaner and high-pressure air to restore its proper seal. If you connect the top of the piston to a vacuum source, you'll see that any lifter that can't maintain a vacuum has obvious check-ball leakage and will likely cause hydraulic lifter noise.
