The internal combustion engine works as a single complex mechanism. The effective interaction of gas distribution and crank-connecting mechanisms and from the engine lubrication system in many ways provide oil surcharge caps. The driver not only should be familiar with the functions performed by the functions, but also to properly diagnose the wear and need to replace the glands.
For what we need oil-challenge caps
The movement of the piston in the cylinder contributes to splashing oil under the skirt. But the thin lubricant film is removed by the oil-circulation rings that are dressed on the piston. On the other hand, in the gas distribution mechanism, the intensition of contacting surfaces occurs.

Under the cover of the block head, a peculiar oil suspension is created. On the border of the cylinder and the cavity over it and there are oil consuming caps. Their task is to prevent oil fog and oil from the feet of the valve into the combustion chamber of the cylinder.
It is not difficult to guess with permanent contact with the valves of the gases distribution mechanism that the caps are experiencing a permanent load. Each valve makes hundreds of movements per minute, and the oil is warm up to high temperatures.
How many and where they stand on the engine
Based on the appointment and work performed, it is easy to install where the oil-challenge caps are located. If we consider the engine assembly, then the cap is dressed on the valve rod. Structurally, the part is a plastic part in the form of a sleeve of a special stable material and a metal base.

The location of the engineering caps in the engine during its disassembly is defined as the head of the cylinder block, at the place of the valve input to the working chamber.
If in the engine 8 valves and 16 valves
Breaking your head about how many oilmaging caps in the 16 valve engine do not have to. The number of these responsible parts is equal to the accuracy of the number of valves. Those. If the engine with 4 cylinders states that 2 valves per cylinder, then the cap will be 8. In more modern motors, where the valves per cylinder 4, the number of glands will be leveling 16. Provided that the engine4-cylinder.
Causes of wear
Along with constant mechanical exposure, the cap is experiencing an aggressive effect of heated oil and impurities in it. Do not forget about the hot exhaust gases at the occurrence of the exhaust tact.
Over time, natural rubber grubes, the walls of the bushings are cracking and abrase. Despite the fact that the maintenance regulations did not define the accurate interval of the receipt of the caps, when the corresponding symptoms appear, it is not worth tightening with a replacement for new parts.
How to determine the need to replace
Among the main criteria that directly indicate the need to replace the oil surcharge caps are called:
Spark plug-in electrodes. The oil has the ability to leak into the combustion chamber.
Increased oil consumption. Compared with the traditional "appetite" 1 liter / 10,000 km, similar consumption increases to a liter for each thousand.
The appearance of a sizogue smoke when exhaust. A part of the oil has time to burn during the compression tact.
Sometimes a dilemma is rising, which is the cause of the sizogo smoke from the exhaust pipe. In error, it is often called such a cause of wear of the details of the cylindrophone group. To finally decide, it is necessary to overhaul the engine or the replacement of the oil-challenge caps, it is enough to check the compression. The normal value of this indicator allows you to confidently indicate the caps.
By the way, briefly the problem of increased oil consumption will make it possible to remove the use of special means. The special additive of the softening of the oil-challenge cap will allow you to restore the functionality of parts a couple of thousand kilometers. There is a additive after 500-700 miles of run after adding. Do not tighten with the repair, most likely similar engine wear symptoms will soon appear again.
How to choose everything you need to work
When contacting the service center, the oil surcharge caps will not be difficult. However, this approach will mean for the owner of the auto option to perform work with the removal of the head of the block, which implies the replacement of gaskets, fastening bolts. Yes, and the time spent here are big. This option means a significant overpayment.
The easiest option is to perform work yourself. To do this, it is worth preparing a tool for replacing the oil-challenge caps and buy a set of consumables for a single engine.
What caps fit: sizes and price
When determining which oil-free caps are better for a particular motor, it is worth paying attention to the original kit. You will receive a high-quality product, and the price does not seem significant.
For example, a set of original spare parts for popular models costs from 1.3 thousand rubles. (Toyota Camry 2.4 L) to 2.2 thousand rubles. (BMW x3 2.5 l). When compared with the available counterparts, the oil-sensitive caps are cheaper than the amount from 800 to 1200 rubles, respectively.
If you select Analogs, do not be lazy to check the corresponding part of the VIN number, or ask the store manager's consultation.
We select the removal
To successfully replace the oilmaging caps without removing the heads, you will need to buy a special tool. As a last resort, it turns out to be borrowed such a set of a neighbor in the garage.
To perform work, you will need a tool, better known as an exhauster. When choosing, it is worth paying attention to the equipment with an appreciation of it to use with a specific engine. The use of universal devices is allowed. However, some "universals" are still calculated on a specific engine type - with HV or SOHS layout.
The tool is designed for clips of valve springs by mechanical pressure. After removing the superstar, access to the oil surcharge caps.
The order of removal and installation do it yourself
At the initial stage of the work, the car is dealers, the ignition coil is turned off and the candles are turned off. The piston of the first cylinder is installed in the upper dead point. Further, to change the oil-challenge caps, the following operations perform:
The valve lid and all hoses are removed. Rocker bolts are turned away.
Remove the rocker. At the same time, control the crackers during removing with the axis. Do not remove the rocker from the axis and do not turn over so that the oil from the hydraulic compensator does not flow.
Install the puller and squeeze the spring. As a result, two crushers are released, which need to be removed (convenient to use tweezers).
We remove the valve plate, get access to the spring and the valve puck.
We write the set detail. It is possible to use either a shock collet or pliers for tightening the cap along the axis.
Before installing a new cap, check the flavor of the valve itself in the guide. If the indicator does not exceed 0.15-0.20 mm, set the valve back.
A new cap on the lubricated valve axis is dressed using a mandrel. Returning in the reverse sequence of spring and valve plate, crackers.
When tightening the bolts of the rocker, use the dynamometer key. Often the tightening torque is set at 50nm.
If it is necessary to change the oil-circulation caps in the cylinders 2 and 3, the pistons are also required to be translated into the extreme position.

Modern technology engines are poorly presented without a good lubricant system. But it is also necessary that the oil does not fall into the cylinders.
What is the valve gland?
Because of such loads, the material from which the softest part is performed becomes more solid. Then there is erasing the working edges of the part. In this case, the engineering caps will have to replace, the engine can also be rinsed or carried out prophylaxis.
However, it is not necessary to think that the glands must be changed every year. Modern manufacturers have already established the culture of these details. The replacement is required once in 100,000 km. But there are motors where the replacement needs to be produced more often.
What are the old oilmaging caps signs of wear? Here they can be seen even outwardly. Worn can be recognized by the Size of the smoke from it can appear for a while only when the engine is started either when braking the motor.
On such a detail, as an oil surcharge cap, signs of wear in the form of smoke - not the only factor. The expert is an increased "appetite" to the oil. In this case, the leaks can not be observed at all. To speak approximately, the flow will increase to 1 liter oil by 1000 km. Also another feature is an arrangement and grinding of electrodes on candles.
How to replace oiling caps?
Many advise to conduct this operation in the certified service station, as the work requires the disassembly of the motor. You can spend this operation and without removing the GBC, it is only stocking of the required amount of patience.
Set of tools
For work, you will need some tools. Usually required which is used when repairing the motor. We will have a passage and a special tool that will burn the valve spring. Tweezers will be needed in order to get crushers. In addition to all this, you need a mandrel, with the help of which I will undergo pressing the glands. You still need a hammer and rods of tin solder. The size of the rod must be no more than 8 cm in diameter.
We carry out a replacement
Removing the oil-challenge caps provide the following actions. First you need to dismantle the cylinder cover. Then we turn the crankshaft. Wash it is necessary until the mark on the camshaft asterisk with the same mark on the bearing housing is not combined. Further removing with the distribution shaft. Now you can fix the asterisk and chain. Disconnect the wires from the spark plug and turn the candles.
In the next step, we press the spring well and remove the valve drive lever. We remove from the lock plate and remove the spring from under the lock. Turn the adjusting screw. You need to screw the tool that can squeeze the valve spring. In a hole that was formed from the removal of the candle, we insert our rods. This is required in order for the valve to remain closed. Now we liberate the cruck. To do this, it is usually necessary to compress the valve spring and spin the bolt of the distributor. Remove the details, remove the tool.
Now you can see the glands. If you do not know how to change the scale caps, you should use the collet clamp. This allows you to remove the seals with the help of light blows. It is not necessary to use screwdrivers, pliers or any other similar tools for reassessing. So you can resort the sleeve.
A new detail should be carefully put on the valve (and at the same time try not to cause damage to its extreme part). Internal surfaces need to be lubricated with oil. So it turns out to move the gland along the valve to the guide bushing. Now it remains lightly knock and finally press the gland.
After successful pressing it is time to collect everything in the reverse order. So you have learned about how to change the oil-challenge caps.
How to choose seals?
Today there are practically no problems with spare parts. However, it is not necessary to exclude the situation when you have to trust not in the parts that the manufacturer recommended, but what is in stores.
If we talk about the choice of oil-challenge glands, then their main purpose is a seal for the valve rods, as well as valve sleeves. These seals must protect the combustion chambers from oil. When oil surges can be seen, signs of wear, it's time to take care of the acquisition of new ones.
You know how these elements are arranged. As it shows the use of details, it is such a solution that allows you to get good results. So, the protection is preserved and then when suddenly the valve terminal turns.
New models of ftorkuchka or acrylate rubber caps are used on modern engines. However, no one else says that they cannot be used on older cars.
If you establish new signs of wear on the old engine, will appear much later, and the motor itself will greatly benefit from such a stroke. This is the optimal solution if the cap is suitable for the landing valve.
It is also important to take into account the profile of the inside of the gland. For example, Japanese engines have caps that are inside have a protrusion. On the guide sleeve in this place the groove. You should not conduct experiments and put such details for smooth bushings.
Long resource caps will ensure the installation of new seals to new engines. If you can put new models of caps on the old motor and nothing will be, then if you put an old model of the gland to a new model of the engine, then anything can happen. Here, the whole thing is not even in which scale caps on constructive features, but in the fact that new power plants work in extremely rigid modes. Old glades simply will not stand such loads. Therefore, their purchase is meaningless.
So, we found out what oil-challenged caps are like wear.
In order for the car engine to worked properly as long as possible, and so that oil and gasoline consumption does not increase, it requires timely prevention or repair. Such mandatory procedures also applies to oil-challenged caps. Next, we will talk in detail about the valves of the valves and consider what it is for the details. In this article, we will answer questions, for what signs you can determine the need to replace the oil-challenge caps and how to change the oil-free caps with their own hands.

General information about oil-giving caps
Masciling caps (seals) are part of the mechanism of oil distribution in the engine. The presence of oil is the main condition of work. Only not everywhere it should be. For example, during its rotation is always in the oil fog. But in the combustion chambers should not be. There is only a fuel and air mixture that burns. If the oil in it is added, the combustion will deteriorate, which will affect the increase in gasoline consumption.
Removal of coke sediments and car in the engine: available methods. Independent flushing of a motor without autopsy, mechanical engine cleaning.
Motors of modern cars have many very small, but very important for its serviceable functioning of parts. If it does not find it in time and not to take appropriate measures, the consequences of this for the power unit, and, accordingly, the budget and nerves of the car enthusiast can be the most sad. An oil surcharge caps include the "smallest things".
They are part of the design of the gas distribution mechanism (timing) of the car internal combustion of the car. The dimensions of them are quite small and they are not in sight, but inside the engine.
As you could understand this article will be devoted to the oil-challenge caps. Here you will learn why the oil-challenge caps are needed and what are the signs of their wear.
Valve and oiling caps.
The oiling caps are needed in engines in order to prevent oil entering and small garbage in the combustion chamber. They are often called valve glands, and this name fully reflects the role they perform.
The oil slimming caps are located directly on the valve rods, and consist of three main parts:
- Base;
- Proper cap;
- Spring.
The base is a sleeve made from steel. She plays the role of the frame of this part and gives it the necessary strength. A proper cap is the main item of the part. It is made of special, resistant to high temperatures and exposure to rubber friction. The cap is installed inside the sleeve, and being mounted on the valve, fits the rod tightly and removes the oil. And the spring is mounted in a special ring excavation cap and provides its most dense adjacent to the rod.
As for the oil that these caps should be removed, it is fed to the gas distribution mechanism with an oil pump. It is designed to lubricate the timing of the timing experiencing friction and increase their resource. At the same time, its ingestion of cylinders through the valve groups is extremely undesirable, because, burning, it forms a nagar accumulating on their walls.
It should be noted that in modern internal combustion engines, oil-sensitive caps have to function in fairly harsh conditions of high temperatures and increased mechanical loads. In addition, substances contained in the removable lubricant are negatively affected. Therefore, the manufacturers of oilmaging caps are used to manufacture the most durable, friction-resistant, thermal and chemical exposure materials.
Wear oil surcharge Caps
Like any other detail of the internal combustion engine, which regularly experiencing a whole combination of negative impacts of various kinds, oiling caps gradually, but steadily wear out. Their most loaded rubber part over time loses elasticity, cracks appear in it. In addition, over time and under the influence of high temperatures, imminently weakens the clamping forces of the spring. As a result, the wear of the oil-challenge caps leads to the fact that the oil is not removed from the valve rods and it enters the combustion chamber of the internal combustion.
As practice shows, the resource of oil-circulation caps, installed in modern internal combustion engines, is approximately 100,000 mileage kilometers. After the car passed this distance, they are subject to replacement. Experts also recommend changing the oil-circulation caps and in the engines of cars, which for a long time were derived from operation.
In addition, it often happens that the oil surcharge caps for one or another reasons are extended prematurely. In such cases, they, of course, also require replacement to new ones. The fact that the time of this kind of engine repair came, testifies several characteristic features.
Signs of wear
Valve stem seals.
The following signs may indicate about the wear of the oil-circulation caps:
- Significantly increased oil consumption;
- The appearance of nagar on the spark plug electrodes;
- The appearance of exhaust gases of blue at the time of engine warming up.
The increase in the "oil appetite" of the engine with the wear of the oil surcharge caps is quite logical and explained. The fact is that the lubricant, which is not removed with them from the valve rods, enters the cylinders and burns. Accordingly, it is irrevocably lost from the lubrication system of the power unit, and the oil has to be treated more often than usual.
Since the oil burns, the combustion products that have blue are outward, staining in the corresponding color exhaust gases. When the engine is warmed up, the oil burns almost completely, so the blue smoke disappears.
Cryo it, if the oil, not filmed by cap, falls into the cylinders, then its smallest drops are settled on the electrodes of the spark plugs. Accordingly, after the combustion, Nagar is formed on them.
The consequences of wear of oil surgery caps
As soon as the listed signs of wear of the oil-challenge caps are beginning to manifest, it should be checked by checking the gas distribution system, and special attention should be paid to precisely oiling caps. Experienced motorists do it on their own, less sophisticated sent to the service station, where the diagnosis produces experienced specialists.
It should be noted that it is not recommended to operate the engine with worn oil-free caps categorically. As practice shows if you ignore this defect and not eliminate it, it is almost inevitable:
- Reduced power of the power unit;
- At idle it will begin to stop periodically;
- Turnover will "swim";
- Compression will significantly fall;
- On the cylinders, pistons and valve saddles will appear Nagar.
As for Nagara, his appearance is really a very serious "bell", since its formation may well lead to a very expensive overhaul of the power unit.
How do oil surcharges change?
If the car owner discovers that the oil slimming caps were worn on his car, they need to be replaced. This procedure is successfully carried out by car maintenance stations.
First, they give the engine to cool, after which they dismantle the timing cover. Next, on the distribution and crankshaft, they make the appropriate labels, after which they remove the camshaft. At the next stage, the valves "dismissed" (that is, pushing springs are removed from them), faulty oil-challenged caps are dismantled. For this, specialists are most often used or ordinary passatsii, or a sewage specially intended for this purpose. The valve rods are then lubricated with oil, after which new oil-challenged caps are put on them. Next, the assembly of the gas distribution mechanism of the car is carried out in the reverse order.
Video on the topic
All modern internal combustion engines are equipped with a whole piece of special sealing. One of them includes oil consuming caps. As you can guess from the name, they are connected with oil in the automotive unit. In general, it is more correct to call such caps with valves. Their task is to prevent situations where surplus oil fall into the combustion chambers. Despite the fact that the oil slimming caps are made from special rubber, their operational resource is quite large. In case of wear of the caps, it is possible to observe an increase in the flow of oil, as well as the formation of a car in the engine and the deterioration of its stability. Let's figure out how many oil-challenged caps are "live", as they have been completed and what affects their operational resource, when and how they need to be changed, and we will also figure it out with the peculiarities of the choice of new products.
Briefly about functions
In the engine, 2 types of valves are isolated: exhaust, intake. Each of the valves is located so that its upper part has contact with the distribution shaft. From this side of the valve during the rotation of the shaft is an oily fog. The type of valve will depend on what is on the other side of it. If this suspension of gasoline droplets, the valve is intake. If the bottom side of the valve goes to the exhaust gas area, the valve is called an exhaust.
Now we return to the topic of oil-challenged caps. Since the camshaft requires a large amount of lubrication for normal operation, overclocking this oil may well be leaked in the engine combustion chambers. It is extremely undesirable. Outlooking caps, they are valve seals, just serve as a barrier between the medium with a large number of hot-sized oil and combustion chambers. Oil that is lubricated by the rod with reciprocating movements, is removed by oil-sensitive caps.
Why do high demands presented to valve glands? Everything is very simple. In the combustion chamber, the oil can get along the valve rod, where it, mixing with the fuel and air mixture, burns. Modern oils have many additives and are not completely burned in principle. When they are combustion, a nagar is formed on the saddles of the valves and the so-called. "Plates". As Nagara accumulates, the valve simply loses the ability to close. Nagar will also form on piston rings, cylinder walls and upper piston planes. All this leads to a serious acceleration of engine wear and a decrease in the quality of its work - the mixture is simply not burned properly. If the caps do not remove the oil and themselves will be affected by the aggressive medium, they cannot be called efficient.
Device and resource of oil-challenge caps
All engine sealing elements seem simple, even uncomplicated. Caps are no exception. As already mentioned, they are made of special rubber. They have a rather complicated form, and if we recall that the quality of the caps are presented with high demands, it is easy to guess that they are not so easy to be in production. Here are from what elements they consist:
Base. This is a steel sleeve performing the role of a solid frame;
Spring. Without spring, the edge of the cap will not fit enough to fit into the rod;
Cap. The main element of the valve sealance. It is manufactured from the acrylate or second head. In the past, the caps from fluoroplast were spread. It is the cap removes the surplus of lubricants from the valve rod.
The use of rubber as the base material for the cap is due to the fact that it is distinguished by resistance to the effects of a chemically aggressive medium and high temperatures. Since manufacturers are interested in that the engine seals are most durable, they began to use this particular material. It cannot be called cheap, so the price of the final product, many motorists consider overestimated. Together with advanced and rather complex production technology, oil-free caps are expensive, but durable seals.
As for the operational resource, everything is not so unequivocal here. Many firms produces valve oil supplies that may not have such a high quality of execution as originals. The point here is that the valve in 60 seconds performs over 1000 clocks. The temperature in this zone is very high, and the caps surrounds hot oil and spent gases. If they are made of low quality materials or have not the most successful geometry, their resource will not be large. Good oiling caps can run over 100 thousand kilometers. In case the car has been idle for a long time (over the year), then the glands will greatly lose in the residual resource. It is determined by the fact that the rubber begins to decrease, and the material of the spring is age, because of which it ceases to press the cap with sufficient force.
Wear oil surcharge Caps
It is not very difficult to determine the wear of the valve seals is not very difficult. It highlights primary and secondary signs of wear, although in some cases they may indicate wear of other engine elements. We will consider these signs in the context of a possible failure of the caps. Primary signs that you cannot do not pay attention to, this is:
Changing the color of exhaust gases. The exhaust becomes more dense and acquires white or bluish color;
Nagar appearance on the exploited ignition candles;
Increasing oil consumption (up to a liter per thousand kilometers).
If something is observed from the listed, the oiling caps need to be inspected. The question of how to get to them, we will look at a little later. Immediately, let's say that with the wear of the caps, it is recommended to inspect the valves and the gas distribution mechanism. The secondary features of the wear of the caps include the following:
Tangible reduction in engine power;
Reducing compression in the engine;
Nagar appearance both on the pistons and on the engine cylinders;
The appearance of "floating" revolutions and the emergence of situations where the motor stalls at idle.
Secondary signs of wear are not so unequivocal, as they may indicate a multiple engine nodes at once. In any case, if you see the above, it is recommended to inspect the aggregate by a specialist. Remember that the appearance of Nagar precedes the engine outlet and further overhaul, with which you can fly to a penny - it is better to be renewed here and allocate a day to inspect the specialist in the automotive units.
Independent replacement of oilmaging caps
Immediately, we note that the manipulation with the engine should not be carried out without having a profile education, of course, of course. If the motorist discovered the release of caps in order and still wants to work with the engine independently, then for the beginning he should be familiar with the manuals. The fact is that the process of removing and replacing caps will directly depend on which model of the car and the engine will have to work. Here you can allocate several stages of the works that are the same for all cars:
Wait until the engine cools off;
Remove the lid of the gas distribution mechanism;
Make markers on camshaft and crankshaft shaft, after which weaken the drive and dismantle camshaft;
Remove the pushing springs of the valve ("dismantling");
With the help of the passage to remove the oil slimming cap;
Grease the valve valve oil and the inside of new caps (before this you need to remove the spring);
By installing the gland in the frame, quickly move it to the rod and pressed until it stops. Apply the force is categorically not recommended - pressing should be carried out with light blows, gradually;
Wear on the springs caps, after which the valves are drumming;
Return engine elements and timing to place.
If the problem with the oil-challenge caps was observed for a long time, it would also have to remove the GBC and clean the internal cavities of the engine from Nagara. It would also be impossible not to note that some oiling caps are made so that their dismantling without special skills and tools is practically impossible. If it seems to you that the work on the replacement was too complicated, it is not necessary to persist - trust this work by a specialist.
Which oiling caps choose
Almost all experts recommend purchasing and install the same engine components that the car manufacturer uses. This recommendation is often disturbed, which, however, does not always have consequences. The fact is that with the development of technologies for the production of oilmaging caps and the use of new materials, the final product may even exceed the original for the operational resource. This is usually true for caps for engines of old cars. For example, rubber caps successfully replace fluoroplastic. We still recommend looking for auto parts by:
Parameters of the car and, in particular, the engine;
Code of existing caps.
So you will definitely find the appropriate option for repair. Be especially careful when searching for caps by car parameters. Everything is important here: model, full information on the engine, vehicle release year. If the original was found, it will be easy to find and analogue. When selecting analogue, it is especially important to pay attention to the manufacturer, as well as the country in which the cap was produced (most manufacturers have plants in several countries). Do not forget that analogs are often formed. The fake is easy to identify in the absence of special protective signs (verification codes, QR codes, holograms), low quality of the execution of the caps themselves, often color of the product, as well as the absence of corporate packaging or discrepancies in packaging design.
As already indicated in the previous paragraph, the analogues of the oil surcharge caps may exceed the originals in terms of performance and operational resource. For example, the factory caps for Mercedes-Benz cars M110 and M123 models (fluoroplastic) can be replaced with more modern counterparts from rubber. You have to choose between the products of the following manufacturers:
ELRING (Germany);
Ajusa (Spain);
NOK (Japan);
Goetze (Germany);
Victor Reinz (Germany-USA).
In fact, these are the same firms that they supply their products to the plants of autocontraces. Under the names of their own brands of these manufacturers, you can find OEM-quality spare parts. Unfortunately, the mass surfactant caps of these firms are often formed. Be especially carefully when choosing analogs from Ajusa, Elring and Victor Reinz. Practice shows that it is the Spanish product for fake especially often, as a result of which the manufacturer itself has not the best reputation.
Not bad analogues can be found in the catalogs of Musashi (Japan), Corteco (Germany), Stone (Japan-USA). Immediately we note that some motorists celebrate the average quality of oil-circulation caps of these firms. From the top three listed firms only the reputation of Corteco spoils a large number of fakes operating the name of the German brand. As for the analogue from little-known packers, it will almost certainly be a product of one of the manufacturers from the list above. There is only low-quality fakes.
To identify the oil-challenge caps, it is worth getting a brand product. Fortunately, today it will be enough to have photos found on the net. Pay attention to several things. First, on labeling. For example, on NOK caps (Japan) there is a marking with the code and the name of the manufacturer. Secondly, fake caps are often performed in the wrong color. For example, complete with corporate products one cap is completely gray, and the second has a black item. In fakes, everything is simple - both caps will be gray. Thirdly, fake products are almost always more branded. Often the outer diameter of fakes by 1.5 millimeters is more than the originals. And, fourth, pay attention to the price. Fakes are always cheaper. If the average price of the cap is a conditional $ 3, and you found the same, but already for $ 1, then it will be fake with a high probability.
The oil slimming cap is an important element of the internal combustion engine. The output of the cap failure in no case cannot be ignored. At first, it leads to an increased oil consumption and to the operation of the engine in anomalous mode, and over time and to the failure of it. Engine repair will cost tens times more expensive than buying oil-challenged caps and work on their installation. Fortunately, the analogues and the originals are quite easy to find. When buying data parts, carefully check their authenticity. The amount of fakes is extremely large, and the fakes are seriously inferior to the originals as execution and can cause the engine to appear in the engine and increasing the flow of oil.
