The majority of drivers get used to the sound of their BMWs. If even a little difference in noise occurs from their car, such as the dreaded ticking sound, they will notice it immediately away. Let’s examine a few causes of this noise coming from your BMW.
- Low Oil Level: The moving parts of your BMW’s engine, like the camshaft, rocker arms, and others, are maintained with special motor oil to ensure optimal performance. If your oil level is low, not all of the parts will be properly lubricated. During this time, you might hear a ticking sound.
- Even if your automobile has sufficient of oil, a bad oil pump will prevent it from getting to the top of the engine. The ticking sound may occur if the pump does not provide enough pressure for optimal lubrication, much like when the oil level is low.
- A loose lifter is a purely mechanical problem in your BMW engine that results in a ticking noise. As your engine operates, the lifter forces the intake and exhaust valves to open. The lifter will tap the camshaft and make a ticking sound if it goes loose.
Low oil levels and faulty oil pumps can be easily fixed if they are discovered in time. On the other hand, a loose lifter calls for a significant repair. If your BMW makes any of these noises, have it serviced right away by a qualified BMW mechanic.

Ineffective Hydraulic Valve Lifter Symptoms
A malfunctioning hydraulic valve lifter’s primary symptom is a grating ticking sound. The noise is brought on by insufficient lubrication and occurs more frequently in colder weather.
Ticking and rattling sounds can also be caused by other problems. On the other hand, the hydraulic valve lifter was a regular culprit in BMWs produced between 2004 and 2015.
What to watch for in a BMW
According to this article, the primary sign of a failing hydraulic valve adjuster is an audible ticking sound that is caused by insufficient lubrication. This component starts to tick and rattle over time if it isn’t properly lubricated, especially when the ambient temperature is lower. While most rattling or ticking noises can be attributed to other problems, if you have a BMW that was produced between 2004 and 2015, you might think about the hydraulic valve lifter as the cause.
How crucial the hydraulic valve lifter is
Unfortunately, the poorly built hydraulic valve lifter in these specific BMW cars is what causes the unpleasant ticking noise that drivers frequently hear. Since there isn’t much space under the hood to begin with, the part is designed to allow for the expansion and contraction of various engine parts when the internal temperature rises, creating room for the parts to grow even slightly. Once the hydraulic valve lifter is “broken in,” it starts to encounter issues that produce the dreaded ticking sound. The main cause of this is an inadequate oil supply, which prevents the part from continuing to function as intended.
What does a ticking noise coming from a car mean?
Your engine’s working parts are kept lubricated by the oil, preventing severe damage from heat and friction. Due to inadequate lubrication, an engine with low oil or low oil pressure may create a ticking noise. If your oil level drops, it can be a sign of oil consumption or an oil leak, both of which need to be fixed right away. You’ll probably see a warning on the dash if your oil pressure is low. Low pressure is a very significant problem that, if left untreated, can completely wreck your engine. It can be brought on by a malfunctioning oil pump or the use of oil with the wrong viscosity.
Why doesn’t my car’s check engine light come on, although it makes a ticking noise?
Hi Le. We appreciate your reaching out to us. A noise like this may be caused by a number of things, but an exhaust or vacuum leak is usually to blame. However, it might also be caused by a damaged or loose air intake, a loose serpentine belt pulley, or a variety of other potential causes. Before making any repairs, you might want to have a qualified mechanic do an inspection to help identify the noise’s cause.

Is a BMW supposed to tick?
There is a ticking sound that many BMW drivers have heard coming from their engines. The more you choose to move the car about, the more often this becomes. This frequently appears between 50,000 and 100,000 kilometers into the BMW’s life. Additionally, it will become more noticeable while you are in heavy traffic and when it is chilly outside for an extended period of time.
Compared to certain other cars, the BMW engine makes this ticking sounds more frequently. This may occasionally indicate a serious issue with your car, while it may just be a typical noise this kind of car makes. You ought to have the problem examined as soon as you can by a competent mechanic because it can be difficult to determine whether this is a problem to be concerned about or not. Since this automobile has some particular features that American cars might not, it is best to work with someone who has previous knowledge with BMWs.
Why may I hear a ticking noise when I’m at rest?
Ticking noises are a given when a valve train is out of adjustment. Usually, uncorrected valve trains are the main cause of ticking noises in engines while they are idle. The valves must open and close once for each complete engine rotation. In a single cam engine, the rocker arm acts as a lever to open the valves while the pushrods are moved by the cam.
The lobes of the camshaft pressurize the valves in an overhead cam engine. Since the valves move quickly and across a small space, it is crucial that the distance between the valve and the pushrod or cam be extremely exact. This distance is managed using shims and other adjustments. The distance does have a tendency to wander outside of tolerance, though, as regular wear and tear occurs.
As these parts move about while the engine is idle, a ticking noise is made. This happens when the engine’s parts have too much flexibility in them. To eliminate excessive play or clearance, new shims can be installed, or the rocker arms can simply be adjusted.
Can you operate a vehicle while it is ticking?
Depending on how the engine is built, a car making a ticking noise can be typical. For instance, fuel-injected engines can cause a ticking sound in an automobile due to the injectors firing. Small electrical valves called fuel injectors create clicking and ticking noises when they open and close fast at idle. The injectors ticking is typical, so you can drive without being concerned.
Can changing the oil generate a ticking sound?
Unusual engine noises are always concerning, but they might be even more so if your maintenance has been up to par.
Periodic oil changes are crucial since they enhance engine performance and provide peace of mind that problems won’t develop.
Ticking typically occurs because there is insufficient lubrication, which prevents the moving parts from moving smoothly.
However, a ticking or tapping sound, particularly after an oil change, cannot be linked to a specific issue way other engine noises can. It can be because of a number different things that could have gone wrong when changing the oil. The potential causes of a ticking sound after an oil change are listed below.
How long can an automobile continue to run?
So, is leaving your automobile idle a bad thing? The vehicle should not, however, be left in that condition for an extended period of time (more than 30 minutes), as it will burn gasoline and harm the environment by producing exhaust gases.
Will changing the oil stop the engine from ticking?
You’ll probably hear a splattering, tickling, or ticking noise coming from the engine if your oil pressure is low or your oil level is low. If the valves or lifters are the source of the noise, adding oil or doing an oil change will silence it. But regrettably, changing the oil won’t stop a rod knock noise.
Can you operate a BMW while using a lifter?
You can keep driving your automobile if the ticking noises are caused by the N52 hydraulic valve lifter problem. Although the issue hasn’t been linked to any known safety concerns, we do not advise driving your BMW without a full diagnosis because the sounds could point to other engine problems. Since driving with engine issues might lead to more expensive repairs down the road, you should have the ticking noises evaluated by a qualified mechanic.
Can a ticking lifter harm something?
The hydraulic valve lifters, also known as hydraulic tappets, are tiny cylinders located directly next to each engine valve in your car. It guarantees quiet, efficient operation of your car. The lifter mechanism will eventually wear down (especially if there isn’t enough or unclean oil), which will cause a ticking or tapping sound.
If you ignore this noise or other bad lifter warning signals, the issue might get worse and seriously harm your car. We’ve compiled a list of problematic lifter symptoms you should never ignore to help you escape the costly repercussions of ignoring a defective hydraulic lifter.
Before we discuss lifter problems, let’s discuss how they operate when they are functioning properly.
Is it safe to operate a vehicle while it is clicking?
Check your engine oil if you hear clicking while driving. If your oil is clean and not low, your car’s starter, battery, axles, or brakes may be the cause of your issue. To identify the problem, thoroughly inspect each component, or get it serviced by a reliable mechanic. A
Cars are naturally noisy, but if you hear a new sound that isn’t a part of your car’s typical symphony, it can be an indication of something more serious. If you don’t identify the issue as soon as possible, it could jeopardize your car and cost you a lot of money. Clicking noises while driving can be an indication of a variety of problems, from low engine oil to loose brake pads. A
What is the cost of fixing an engine tick?
Repairing a knocking engine might run between $2,000 and $3,000 on average for materials and labor. You might also have to pay to replace other parts if the damage is more severe. Avoid delaying this repair because doing so will simply make the damage worse (and the expenses will rise)
Can lifters develop a tick from cheap oil?
Low Levels of Oil Your oil levels being too low is another frequent cause of your engine starting to tick. The same issues that arise from tainted and filthy oil might also arise from low oil levels. Hydraulic lifters will perform poorly if there is not enough oil for lubrication.
Should I be concerned about the lifter tick?
Because a lifter tick or tap can result in major and costly issues with your engine, you should have it addressed as soon as possible.
Is it pricey to remedy a lifter tick?
The replacement of one or more lifters is an expensive and time-consuming procedure. You should typically budget between $1,000 and $2,500 if you decide to hire a professional to complete the task. Naturally, the precise price will depend on a number of criteria, including the year, make, and model of your car.
