If you’re a car lover, then you must be familiar with lifters. If you’re not, though, I’ll explain what they’re all about.
A hydraulic valve lifter, which is often simply called a lifter, is a tiny cylinder that’s well attached to the end of a pushrod or a rocker arm. This is where it meets the valve.
The purpose of a lifter is to make a vehicle’s engine quieter while also improving its performance and ensuring that it has a long, healthy life. Although lifters are meant to prevent unwanted noise and to be quiet themselves, they can sometimes become noisy over time. This is a common problem found in older cars and those that have racked up a lot of mileage, especially if a particular car hasn’t been serviced regularly.
Un sollevatore rumoroso può causare danni?
Questa è una domanda comune che la gente fa, e la risposta dipende dal tipo di rumore che fa il sollevatore e da quanto tempo il rumore tende a durare.
Un sollevatore può produrre suoni di battito e clic che possono durare solo pochi istanti, ma potrebbero anche durare per tutto il periodo di tempo in cui il motore funziona.
The type of engine lifter noise you’re hearing and its duration are the most important things when it comes to determining how harmful a noisy lifter can be.
In most cases, this wouldn’t be a serious problem, but it can point to an accumulation of sludge and dirt that’s starting to interfere with the function of the lifter. When this problem occurs, you can easily clean it with some oil additives, and the issue should be solved relatively quickly.
Tuttavia, se il ticchettio e il battito continuano per un periodo di tempo più lungo, allora questo potrebbe essere un sintomo di un problema di fondo che dovrebbe essere risolto il prima possibile.
If the problem isn’t solved as quickly as possible, it can prevent other components of a vehicle’s engine from functioning properly, and even cause very serious damage to a car over time.
Come calmare un sollevatore rumoroso
What You’ll Need:
Liqui Moly 2037 Pro-Line Engine Flush – You can use these oil additives to get rid of accumulated dirt in your engine, which helps to quiet a noisy lifter.
Lucas 10001 stabilizzatore di olio pesante – You can also use this oil stabilizer to get rid of accumulated dirt in your engine.
Misuratore di pressione – This will help you adjust your lifter after changing your car’s oil and cleaning it with oil additives.
1. Cambiare l'olio
This step is very important, as every mechanical part of a vehicle’s engine requires the correct oil for lubrication. If the oil you’re using isn’t suitable for la tua auto—if it is, perhaps, more or less heavy than your engine needs—it won’t lubricate the engine properly and can actually cause some serious problems.
This improper lubrication can cause metal parts that come into contact with one another to produce annoying tapping sounds. If this continues for a period of time, grime and dirt can build up within the engine’s oil filters, which can then prevent further lubrication of the engine’s components.
To stop this noise once and for all, and prevent possible damage to the engine due to a lack of lubrication, you’ll have to change your oil by using one with the right gradation for your car’s engine.
If you’re wondering how to choose the right oil for your engine, here’s a video you can check out:
2. Pulire i sollevatori con additivi per olio
Earlier, I mentioned that there are ways to stop the tapping sound in your car’s engine that occurs when you start the motor.
The best way to solve this problem is by cleaning the lifters with oil additives, but it’s also a good idea to clean more than the lifters. You can use this amazing product to clean the rockers and valves, thereby removing any grime and specks of dirt that have accumulated inside. Oil additives don’t change the viscosity of the oil that’s used in your engine, so you don’t have to worry about ruining the oil, now that you’ve found the right one.
Vi consiglio vivamente di passare attraverso questo processo abbastanza spesso, perché può fare una grande differenza nella vostra auto, e può farvi risparmiare tonnellate di soldi pure.
Sbarazzarsi dello sporco accumulato è probabilmente l'opzione più conveniente quando si tratta di risolvere il problema dei sollevatori rumorosi.
Here’s another video guide that will give you more information about cleaning your engine’s lifters with oil additives.

I personally haven’t used them, but based on the video and the positive user reviews, it looks like they’ll make the engine entirely clean.
3. Regola i tuoi sollevatori
If you’ve already cleaned your lifters with oil additives and have changed your car’s oil to the correct one, but you’re still hearing rumori striduli, then you should adjust the engine’s lifters.
To do this, the first thing you’ll need is a spessimetro that you can wedge between one of your engine’s rocker arms and the valve stem. Now, you’ll have to adjust the valve adjustment screw to the correct clearance, but before doing this, check out the workmanship manual and find the correct factory settings to adjust it to.
Here’s a video guide that can teach you more about adjusting the lifters:
4. Replace a Bent Pushrod
Se i rumori di battito o ticchettio persistono ancora, la seconda parte del treno valvole che potrebbe essere difettosa sono le aste di spinta. Quello che si può fare qui è controllare se tutte le aste di spinta sono dritte - se qualcuna di esse è piegata, quella potrebbe colpire altre parti del motore ogni volta che il sollevatore la spinge.
A bent rod usually indicates that you’ve been a bit too heavy-handed with the gas pedal. If the speed of the depression bends one or more of the rods, the only thing left to do is replace the faulty ones with new ones. The rods I’ve seen online are very affordable, so this shouldn’t be too much of a hassle.
To replace one, all you’ll need to do is unscrew the rocker arms and take out the bent pushrod. Then, carefully check and see if any of the others are bent by rolling them across a flat surface.
If you’re not skilled at fixing vehicles, I highly recommend that you take yours to a mechanic to have a bent pushrod replaced. The process can be very hard and may take up to six hours, even for a professional.
Regardless of who carries out the job, it’s best to get this sort of fix done in a timely manner. If a bent pushrod is left to clang against the engine, it could do some serious damage.
Conclusione
