Oil scraper caps on Niva are parts of the gas distribution mechanism of a car engine, the task of which is to prevent lubricant from entering the combustion chamber. Made of metal and special rubber, these elements fit tightly to the valves, but over time they wear out and break down.
Their rubber part becomes less elastic and may separate from the base. Oil begins to pass through, and the consumption of lubricants by the engine increases. This means that the oil on the Niva’s removable caps needs to be replaced.
This process is complex, but can be done on your own if you familiarize yourself with the stages of the work and prepare the appropriate tools.
Reasons for replacement
On average, on domestic cars, such as the VAZ 21214 and other models, they are replaced approximately every 80,000 km. For modern imported cars, the interval approximately doubles or triples.
Signs of the need to install new caps on the Niva may include:
- high oil consumption;
- the appearance of blue smoke when the engine accelerates sharply or, conversely, when braking using the engine;
- an unreasonable increase in gasoline consumption (when traveling the same sections of the route and under similar driving conditions).
Fake and original
Be careful when buying, there are a lot of fakes. Usually, when you look at a photo of the packaging on the Internet, you already understand that it’s crap. There isn't even a verification code. Since I bring spare parts from European warehouses and Scandinavian warehouses, I have nothing to be ashamed of. I will list several features of original products:
individual code
- EACH package of caps has its own individual code. Even if you don’t have a computer at hand, just take two packages; the codes should not match.
- There is a hologram stuck on the packaging; it’s not just “glitter.” The four digits from the hologram must match the outermost digits of the digital code.
- If you have a computer, on the manufacturer’s page, you can enter a digital code and verify the originality of the product.

Preparing the tool for work
List of necessary equipment:
- screwdrivers and wrenches;
- desiccant;
- torque wrench;
- tweezers;
- inertial removable device;
- rod (d = 8 mm) made of tin.
During preparation, the battery is disconnected and the spark plugs are removed. It is also necessary to dismantle other parts in turn - from the bearing housing and camshaft to the drive levers, springs and valves.
When dismantling the shaft, set the pistons of cylinders No. 1 and 4 to TDC (the conventional position of zero degrees of crank rotation), preventing the loosened valves from falling inward.

Good afternoon do you have a vibration stand?
Hello! I need to replace the rear brake pads on a Peugeot Partner Teepee. Is it possible to do this at your place and what is the price for such work? Thank you.
Hello, please tell me how much it costs to repair the front axle gearbox of a 2005 Tuareg? And when can you come?
Main stages
The next point of work is to install the rod in the spark plug hole. Thus, it is located between the piston plate and the valve.
This is followed by placing the pressure bracket of the desuction tool on the spring plate and securing the support bracket using a nut located on the mounting pin.
Now required:
- compressing the valve spring with a depressurizer;
- removing two crackers (using tweezers);
- removing the desiccant;
- removing the spring plate;
- removing both springs, both lower and upper;
- removing the support washer from the intravalve spring;
- installing the collet of the removable device on the part being removed;
Using the upper striker of the puller, compress the collet (by hitting the lower striker with it) and compress the cap (impacts are applied to the nut).
To protect the replacement part from damage during pressing, a special installation sleeve must be located on the valve stem. Usually it comes with new consumables.
Now, having applied lubricant to the inner surface of the cap, it is pressed down along the bushing (all the way).
After this, install the valve elements back and proceed to the next stage - removing the rod and installing the crackers in place (lightly hitting the end of the rod with a hammer). Now we need to replace the parts of the remaining valves, turn the shaft half a turn and install the pistons of the two remaining cylinders (No. 2 and 3) at TDC.
In the same way, change all the caps, and then turn the shaft another one and a half turns.

Rating of the best manufacturers of oil reflective caps
The same model of valve stem seal from different manufacturers
A review of valve stem seals with their brief characteristics, positive and negative sides, indication of conveyor applications and current prices will help you choose parts for a specific engine.
The table below contains valve seals from all the most popular manufacturers, available in Russian retail.
Valve seals: manufacturer ratings
| Manufacturer | A distinctive feature of the brand, the caps themselves | Which cars are most often installed on from the factory? | Price for summer 2022 in rubles* per 1 piece |
| Elring | Elasticity of rubber, good wear resistance, which is achieved through the selection of materials for various types of engines and high-quality casting. In addition to classic fluorine rubber, polyacrylic rubber, nitrile rubber, Teflon and other modern materials are used | BMW, Mercedes-Benz, Porsche, Toyota, Volkswagen, MAN, Iveco, DAF, Renault | From 150 |
| Victor Reinz | Good caps made of heat-resistant but flexible fluorine rubber. The original is often green in color (dark shades); it can also be black. They are distinguished by good adherence to geometry, which effectively removes excess oil and prevents its consumption. | BMW, Mercedes-Benz, VAG, Nissan, Opel, Renault, Fiat, Ford | From 150 |
| Corteco | Valve seals from one of the world's largest manufacturers and suppliers of automotive seals. They produce both domestic and discontinued models. They are made mainly from fluorine rubber, which combines elasticity and heat resistance; other fluorine-containing materials are used less frequently. | Alfa Romeo, BMW, Audi, Citroen, Ford, Fiat, Isuzu, Lancia, Iveco, MAN, Nissan, Opel, Peugeot, Mercedes Benz, Renault, Saab, Rover, Volkswagen. | From 100 |
| NOK | Japanese valve seals, factory installed on many local brands. They are distinguished by high quality workmanship and the correct selection of materials. They last a long time, and with gentle operation they last longer than the allotted resource. Often in Corteco packages you can find exactly NOK valve stem seals (as evidenced by the casting mark), because both companies belong to the same concern. | Toyota, Honda, Lexus, Mitsubishi, Nissan, Suzuki | From 150 |
| Goetze | German valve stem seals are often made of fluorine rubber or acrylate rubber. Teflon and other heat-resistant polymers with fluorine are used only for rare product models. | BMW, Fiat, Renault, Ford | From 100 |
| Glaser | Budget valve stem seals of good quality, originally from Spain. Elastic, they cut off oil well under normal operating conditions. Among the disadvantages is the fear of overheating. | Suzuki, Nissan, SEAT, Chrysler, John Deere, Ford. | From 50 |
| Ajusa | Inexpensive, but high-quality valve stem seals made of soft fluorine rubber. They work for 60–100 thousand km without problems, and if you regularly operate the engine in a gentle mode, even more. | SEAT, Nissan, Daewoo, Fiat, VAG and others. | From 100 |
| THO | Japanese THO valve seals combine elasticity, heat resistance, high precision performance and affordable price tags. Original parts serve the allotted 100 thousand km and even more. | Nissan Suzuki, Mitsubishi, Toyota | From 50 |
| Payen | Affordable MSCs made from high-quality fluorine rubber. They are distinguished by elasticity and at the same time have a long resource. They are also notable for the fact that they rarely become victims of counterfeits in Russia. | Ford, General Motors, Mercedes, Renault, Honda, Chrysler | From 70 |
| S.M. | Inexpensive, but high-quality valve stem seals. Viton fluorine rubber is used for production, combining elasticity and durability. | Aprilia, Audi, Bitzer, BMW, Copeland, DaimlerChrysler, Delmag, Deutz, Ducati, Ferrari, Hatz, Renault, Rotax, Voxan | From 30 |
*Not all manufacturers sell oil seals individually. They are often supplied in sets of 8, 10, 12 or 16 pieces, so the prices are approximate, based on the calculation “set price/quantity of MSK = price of 1 piece”. Exact prices depend greatly on the engine model.
Elring valve stem seals
Elring is a German manufacturer of seals for automobiles, supplying products to assembly lines of more than 50 European and Asian brands. For a number of trucks and special vehicles, its oil seals and other seals have no alternatives, so the same Elring is usually sold in branded packaging.
Thanks to the use of heat-resistant fluorinated rubber, they have a long service life, adhere well to the valve journals and effectively remove excess oil. Some oil seals use Teflon, which is a substance with one of the lowest coefficients of friction and is not afraid of heat.
Characteristics of Elring valve seals:
Victor Reinz valve stem seals
The Victor Reinz company has two homelands - the USA and Germany, as it belongs to the Dana corporation trademark (known to many car enthusiasts as a manufacturer of transmission units). Formed as a result of the merger of the German company Reinz and the American Victor.
The company has production all over the world and supplies parts to the assembly lines of many automobile factories. Its valve stem seals are distinguished by high quality, long service life and increased oil removal efficiency (reducing oil waste). In Russia, the main problem of the brand is the abundance of fakes.
Characteristics of Victor Reinz valve seals:
Corteco valve stem seals
Corteco is an Italian brand owned by the German concern Freudenberg. The company is one of the largest manufacturers of seals in the world.
Thanks to the use of fluorine rubber and a well-thought-out shape, its valve stem seals have a good service life and retain elasticity at low and high temperatures. They differ in their affordable cost from 100 rubles per part.
Characteristics of Corteco valve seals:
NOK valve stem seals
NOK is a Japanese manufacturer of valve stem seals, supplying products to car factories in this country. Its MSCs are made of heat-resistant rubber based on fluorine rubber, have a good service life and are elastic. Original NOK oil seals for intake and exhaust valves are often slightly different in appearance (for example, a white stripe on the exhaust valves). Packaged sets under the original brand are relatively rare.
Characteristics of NOK valve seals:
Goetze valve stem seals
Goetze is a trademark of Federal Mogul Corporation. This German brand is known for its piston rings, cylinder liners and other metal engine components, and also produces sealing elements.
Goetze valve seals are affordable, but at the same time have an acceptable service life. The downside of the company on the Russian market is the abundance of fakes. Counterfeit valve stem seals rarely last more than 20 thousand km, which is why some motorists treat the brand with disdain, leaving negative reviews. But, if you take original spare parts, they will last more than 60 thousand km.
Characteristics of Goetze valve seals:
Glaser valve stem seals
Glaser is a Spanish manufacturer of auto parts that has been operating since the 60s of the last century. Today the company belongs to the Dana concern, as does Victor Reinz. The range includes a wide selection of seals made of heat-resistant rubber, as well as Teflon. Their distinctive feature is the combination of low prices and acceptable quality.
This is not Elring in terms of durability, but its seals are noticeably superior to various Chinese products of little-known brands. The main thing is to change the oil in a timely manner and not to overheat the internal combustion engine. There are few fakes, which can be considered a plus.
Characteristics of Glaser valve seals:
Ajusa valve stem seals
Ajusa is another Spanish manufacturer of valve seals. Valve seals from this company are supplied to the assembly lines of many car factories, but are not very widely represented in retail. The MSCs themselves are good, they last up to 100 thousand km, and sometimes more, but there are many fakes on the market. It is sometimes difficult to distinguish them; the main test criterion is elasticity. The original is quite soft, but at the same time durable, while the counterfeit is often made from “oak” rubber.
Characteristics of Ajusa valve seals:
THO valve stem seals
The THO company is a Japanese manufacturer of valve stem seals, supplying them to the conveyors of local car factories. There are many models on sale that are compatible with Japanese brands, in particular, new and old Toyota, Lexus, Mitsubishi. Original valve seals have good elasticity and have a long service life. They are produced on the basis of their own research developments and taking into account all the necessary requirements.
Characteristics of THO valve seals:
Payen valve stem seals
Payen is a French manufacturer of engine seals, like Goetze, owned by Federal Mogul. The brand’s valve seals have good elasticity, are resistant to heat and can last up to 100 thousand km. The company is not very well known in Russia, so it is not often counterfeited.
Characteristics of Payen valve seals:
Valve seals SM
Oil scraper seals from the German manufacturer Schottle Motorenteile GmbH are sold under the SM brand. In addition, the company's products are available under the NE and NPR brands.
Oil seals combine low cost and long service life; they quietly serve the allotted 100 thousand km with timely engine maintenance. Counterfeit brands are extremely rare in Russia, which can also be considered an advantage. But, since it is not so easy to find them in mass retail, these valve seals close the rating of valve stem seals.
Characteristics of SM valve seals:
Having determined for yourself which company's valve stem seals are better, check their authenticity before installation. This is an inexpensive spare part, but replacing it is difficult and time-consuming, since it requires disassembly, and in some cases, dismantling of the cylinder head. It’s better to immediately pay a little more for genuine components and forget about the problem for several years, than to have to deal with replacing fake oil seals again after 10 or 20 thousand km.

A little theory
The main task of valve stem seals is to seal the valve-guide pair. So that oil that is absolutely not needed there does not get into the combustion chamber. By the way, caps are important only on the intake valves, since it is in the intake tract that vacuum is formed. We develop excess pressure in the exhaust tract, so by and large the valve stem seals play a rather “decorative role” there. In this regard, the Americans distinguished themselves, sometimes with a full set of gaskets for the engine, NO exhaust valve caps AT ALL. In the old, ancient times, caps were made of rubber, caoutchouc and fluoroplastic. Now the materials are completely synthetic. The most popular are Acrylic (working temperature range -40C to +180C) and Viton (working temperature range -40C to +250C). The second material is more modern and lasts longer. The selection of valve stem seals for our valves is very large. Elring (Germany), Goetze (Germany), Victor Reinz (Germany), Corteco (Italy). A couple of times I was let down by the quality of the caps and cuffs made by Ajusa (Spain). After that I don't recommend them. The Kirovochepetsk brand “reserve” has a very good price-quality ratio, but unfortunately it is very difficult to find original products. Sometimes on forums you can hear the phrase, I put Audi or BMW caps on the car. This is a misconception, since automakers do not produce these items themselves, but place orders and purchase products from the above-mentioned manufacturers of rubber products.
