How To Quieten BMW Lifters?


For the lifters BMW promotes, there is a “bleeding” process. In essence, you rotate at 2500 RPMs for three minutes. Repeat several times. The specifics are probably somewhere on this forum. Try Googling “lifters bleeding technique”

How can you silence the engine in your car?

The best thing to do is change the oil after making sure that a worn-out lifter or another damaged element is not the source of the lifter ticking. Before adding new oil, drain the entire amount of oil that is currently in the engine. Ensure that the brand of oil you are replacing is exactly what the manufacturer recommends. Make sure it is synthetic oil if you can. Use a synthetic blend if you can’t acquire synthetic oil.

After changing the oil, you should let the automobile run for around 30 minutes to allow the oil to circulate throughout the system. After doing this, the lifter noise should stop if it was caused by an oil issue.

Try again to check if you have a component problem if this doesn’t fix the issue. Verify the rocker arm is securely fastened, the pushrods are straight, and the lifters themselves appear to be unharmed. As necessary, you can tighten or loosen the valve lash, which is the distance between the rocker arms and the valves. Although hydraulic valve lifters automatically adjust themselves, if all else fails, this might be the answer. Undoubtedly, many people cannot perform these tasks without a mechanic’s training.

It’s generally the user’s behavior that is to blame if your automobile or bike’s hydraulic lifters are only recently becoming noisy despite regular servicing.

Many vehicles, both diesel and gasoline-powered, are only utilized for brief distances or, what’s worse, for brief and infrequent distances.

Contrary to popular belief, if this is your situation, resolving loud lifters may be as easy as driving or riding your bike far enough.

You could discover that thoroughly warming up the engine for a lengthy time can significantly reduce noise from noisy lifters by adequately flushing warm oil through the entire system and assisting in preventing lifters from clogging.

Of course, in order to exploit this method to its fullest potential, an oil and filter change should come first.

Be advised that no amount of oil changes will quiet lifters that are already noisy if your automobile or bike has solid lifters that are suffering from lifter tick.

I would also advise avoiding making any lengthy trips with solid lifters until getting your valve clearances corrected.

This could result in unnecessary engine wear that could be easily avoided.

How it occurs

The lifter, a tiny cylinder often found where the rocket arm and valve meet in the engine, is the source of the ticking sound. The lifter, also known as the hydraulic valve lifter, is primarily responsible for keeping the engine quiet while it is operating. The hydraulic valve lifter also contributes to the enhancement of the vehicle’s performance and durability.

When this lifter begins to exhibit certain flaws, it is nearly impossible to silence it. Of course, that negates the whole point of it—to keep the engine quiet. If anything, a lifter ticking issue is much more alarming than the real engine noise and may even result in unnecessarily high levels of worry while driving. This obviously detracts from the flawless driving experience that BMW cars are known for.

Replacing the Oil

Your car’s engine needs to be properly maintained and lubricated, just like any other mechanical component or engine.

If you use oil that is not appropriate for your automobile, such as oil that is heavier or lighter than what your car requires, it won’t lubricate well and could lead to issues.

The lifter tick noises that are an issue here are caused by poor lubrication of metal parts that come into contact with one another.

If the tapping and rubbing continue for an extended period of time, the oil filters in the engine may fill up with too much debris and sludge, which may prohibit the engine parts from receiving additional lubrication.

Regular oil changes are recommended, although in the majority of situations, a quiet ticking noise in the engine can be easily fixed.

You must provide your engine with the required lubrication, which can be accomplished with the appropriate sort of oil, in order to stop this issue and stop your engine from running on its own.

You will need to determine the proper oil grade for the engine in your automobile and change it accordingly.

The subject of how to select the proper oil for your engine is one that keeps coming up.

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.

Will noisy lifters be quieted by synthetic oil?

Can synthetic oils therefore silence noisy lifters?

Whether or whether your lifter is producing noise depends on the cause. If you haven’t changed your oil in a while, all you need to do is do it with a high-quality synthetic oil, such as Royal Purple High-Performance Synthetic Oil.

Will quieter lifters be achieved with heavier oil?

Heavy oil does little to reduce hydraulic lifter noise. Because thicker oil takes longer to reach the top of the engine, you most likely to have the opposite result. Louder tapping or ticking is produced by the lifter. Hydraulic valve lifters are standard in the majority of automobiles. There are no lifters (unless they have overhead cams, in which case there are.) To allow oil to enter, these lifters have a tiny hole in the body of the machine. When the engine is cold, heavy oil may not be able to fill the lifter rapidly, and you will hear the lifters tapping. As the motor and oil warm up, the noise normally stops. If the tapping persists even after the car has warmed up, you might have one or more damaged lifters. Lifter noise is more likely to occur when any oil becomes more contaminated; heavier oil just exacerbates the issue.

Make careful to replace your oil frequently, regardless of the type you are using—even a heavy oil. The suggested ranges from 3,000 to 5,000 miles. Every 10,000 miles is also standard, I suppose. yet not really useful. The adversary of effective lubrication and long motor life is dirty oil.

Will thicker oil quiet the lifter?

Depending on what the true reason for the engine’s noise is. Think about the right use of motor oil before deciding whether it can quiet that noisy engine. Motor oil works to lubricate moving parts and guard against wear damage brought on by movement and metal-to-metal contact. By removing harmful deposits from lubricated surfaces and cleaning them, motor oil also offers protection to those surfaces. Corrosive acids that develop in the engine environment’s heat and pressure are neutralized by motor oil. Finally, motor oil plays a crucial role in dispersing heat and moving it away from engine components.

If or not the cause(s) of the noise are related to any of those oil functions will determine whether motor oil can reduce engine noise. The first possibility—metal on metal contact—would be the most obvious. However, if this is the cause of engine noise, it’s most likely because you have insufficient oil to begin with, which prevents enough oil from getting through to adequately lubricate all of the parts.

The valves of the engine frequently make a “clattering noise” when there is low oil volume or low oil pressure. This may result from both a lack of oil and an oil that is too old and beginning to froth or break down. In either case, the engine will be noisy because not enough lubricant is reaching those areas. simple answer? To return the oil volume to the right level, change the oil or add more oil. Also bear in mind that if the oil level is very low, a mechanical problem, such as an oil leak, is what caused the oil to be consumed over time. The noise will stop if you add extra oil, but the oil leak that is the root of the problem won’t be fixed.

Which oil works best for noisy lifters?

  • The hydraulic lifter additive Liqui Moly 20004.
  • MM13R Mystery Oil by Marvel
  • The premium synthetic engine treatment from BestLine is 853796001049
  • Oil additive for TriboTEX used in automobile engines.
  • Items from Bar Concentrate for Rislone Engine Treatment

What causes noise from valve lifters?

When the push rod or camshaft doesn’t maintain constant contact with the lifters, a lifter tick results. This could be as a result of the lifter wearing out, which occurs frequently with hydraulic lifters, or the valve becoming out of alignment.

When heated, does lifter noise disappear?

The noise you are describing resembles that made by hydraulic lifters, which are a component of the valve train. The oil has had a chance to fall back into the oil pan when the engine is cold or in the mornings as a result of gravity. As you mention, the engine can make a ticking noise when you start it when it’s cold. This occurs while the lifters are initially moving without oil. The ticking sound should get lighter and finally stop when the engine warms up and oil circulates back up to the top of the motor, where the lifters are located. A recent oil change would be advised in order to resolve issue. Sludge that might also be a factor in any potential lack of oil circulation will be removed by using fresh oil. Use the noise as a reference for future oil changes, and if it persists or worsens, have a mechanic have a look at it because there may be a problem.

Can you operate a BMW while using a lifter?

The N52 lifter tick issue is not known to cause any problems. You can keep operating your BMW, however it is not advised. Drivers may hear noises from a variety of engine issues besides the lifter ticking issue. It is advised that you have the symptom evaluated by a reputable BMW expert.

Why does my BMW sound like it’s ticking?

The majority of drivers get used to the sound of their BMWs. They will immediately become aware of any difference in sounds coming from their car, even if it’s only the dreaded ticking sound. 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.
