Why oil in wells on VAZ 2112. Why oil appears in a rubber and what to do to eliminate it. Bad valve cover seal

Each brand and model of the car has its own distinctive features. For example, the VAZ ten very often suffers from the fact that its candlestones are often "bathed" in oil after a certain operating period. The reasons for the manifestation of such trouble can be the most different, but one knows exactly: it depends to one degree or another on the type of engine. In this article we will analyze where this problem appears, and how to clean the well of the spark plug from the oil that has fallen into it.

Why oil appears in candle pads

Any flow in each mechanism of the car, first of all, is caused by a prudent gasket. Of course, when the oil begins to accumulate in candle wellsThis is not so dangerous. For example, if you compare with such a problem as entering the same lubricant on the CCC.

What is the danger of oil getting into wells

The most serious thing that can occur in this case, is softened by a rubber insulator of high-voltage wiring and a breakdown. But this does not mean that it is possible to further allow the oil to accumulate. If you notice it, immediately change the gasket. In 100% of cases at first it will help. What threatens the oil formed in candlestones in this case? The further this case will be postponed, the more the resource of the candles will decrease. This will lead to constant financial costs for their replacement.

We produce phased repair

The reasons for the appearance of motor oil in candlestones, we have already found out with you. Now it is worth talking about how to eliminate oil entering the candlestones. First need to prepare all consumables and spare parts. For high-quality work on eliminating engine oil seepage, you will need the following:

Laying valve cover - 2 pieces.

Spray WD-40 and silicone grease.

Candle shuttle glands - 4 pieces.

Motor cleaner.

Strike with everything necessary, proceed to work. Easier this process Conditionally divided into four stages:

1. Removing the valve cover.

2. Dismantling of wells.

3. Removing old gaskets and installing new ones.

4. Reverse installation.

So, start your work:

1. Remove the plastic cover power aggregate and receiver.

2. All openings of the intake manifold are tightly close. It is necessary to prevent extra items inward.

3. Remove the ignition module and the ventilation hose from the cap covers.

4. Key to "10" unscrew the bolt bracket of the nozzle wire connector.

5. Clay on "8" unscrew the valve cover screws.

6. Remove the GBC cover.

Next, you should check the hydraulic switch. An ordinary dummy is slightly tapped on it and observe. It must be pressed with great effort. But if with a minimal press, he succumbed, then it should be changed.

Important! Diagnosing a hydrotherapler, pay attention to the cam distribution Vala It was directed toward him. It is necessary!

Consider the situation when the hydrotherapler requires replacement.

1. First of all, remove the gear pulleys of the camshaft and the wire from the oil pressure sensor.

3. Remove the bolt that connects the back of the motor and the bar.

4. Then remove the nuts with the key to "15" and remove the rear support bracket together with the camshaft bearings housing.

5. Remove the ignition candle guides from the last guide tubes.

6. Then, out of the housing, pull the camshafts, not forgetting about the glands.

7. Remove the two rear cylinder head plugs and camshaft bearing housing.

8. Remove the hydrotherapler from the head nest by attaching to his end magnet.

Collecting the GBC, before carefully clean it from dirt, and the bearing body - from the oil and the old sealant. Fist shafts and cervical supports. Lubricate with new oil. On the surface of the bearing housing, which is adjacent to the GBC, apply the sealant "Lokate No. 574". Install the case in place. Next, lubricate sealing rings and mount the guide tubes into the holes of the cylinder block and the bearings housing. After pressing new camshaft glands and install the caps from the opposite sides. We sincerely hope that this material helped you figure out how to remove the accumulated engine oil from the candlestones.

In the cavity to screw the spark plugs should not be any technical fluids. If you discovered the oil in the candlestones, we recommend that you fix the cause of this malfunction as soon as possible. Consider what is dangerous such a phenomenon, as well as the procedure for sealing compounds with the help of sealant, replace the glands, sealing rings using the example of VAZ and Toyota engines.

The main reason

The oil in the candlestones falls through the leaks of the junction of the elements separating the well from the inside of the GBC. There are several options for the design of the block head.

Carter ventilation system

The increased pressure of crankcase gases is one of the main causes of the accelerated breakthrough of oil through the seals of the candle holes. A closed type implies a mixture of a mixture of water vapor, gasoline and exhaust gases back to the intake manifold.

The PCV valve is responsible for dosing a portion of gases. If for any reason the valve will not cope with its task, an overpressure is formed inside the GBC. The cause of the malfunction can be both in the valve itself and in the worn-out cylindropore group. With worn compression rings, an increased gap between pistons and cylinders, the Carter ventilation system is harder to cope with its task.

In case of abundant fogging around the gasket of the valve cover, pallet, candlestones, we strongly recommend checking the ventilation of the crankcase. With an increased pressure of the exhaust gases, the replacement of gaskets with applying anaerobic sealant will only give a short-term effect.

Symptoms and consequences

To determine the malfunction, it is enough to pull out the tips of GDP / ignition modules from the wells and unscrew the candles. Oil film on the elements and will be the main sign of leakage. If it is not possible to eliminate the cause of oil in time, will lose power in all or certain modes of operation, which can also be poured in. Most likely, due to the cylinders on dashboard CHECK Engine will light up.

Leads to such consequences the negative impact of motor oil on the tip seal high voltage wires, ignition coil modules. The oil medium creates favorable conditions for the breakdown of the spark, as a result of which the combustion of the TPVS in the cylinder is disturbed.

Replacing the seals on the VAZ 2112 1.5 l, 16 valves

To determine the type of device of the candle cavities, unscrew the candles and look inside the well. The option from inserts has smooth walls from the beginning to the end of the opening. On the engines of VAZ 21126, the joint of the valve plane of the valve cover and the bed of camshafts will be visible.

To replace the glands on the VAZ 2112, it is necessary to dismantle the plastic cover, the inlet receiver, the ignition module, the ventilation hose of crankcase gases. Wells are extracted using a slotted screwdriver (drip screwdriver it is necessary to the upper cut). Make sure that the bottom gland remains after the exit on the tube. Clean inserts before installing the seals. Nizhny gland need to smear motor Oil. Using the appropriate diameter drawer, press the insert to the characteristic click.

Candles at the time of work will be twisted, so make sure that the cylinders do not get trash or third-party items.

On the video you can see how with the help of a homemade puller, you can get inserts to replace the glands of the candlestones without removing the valve cover, receiver.

Engines 21126.

On cars in Lada Priora, Kalina, grant from the engine model 21126, you need to shoot not only hinged equipment and the valve cover, but also the gears of distribution shafts, bed. Elimination of the causes of oil entering the candlestones is to apply high-quality anaerobic sealant. The use of silicone gasket sealant will not be as efficient.

The sealant must be applied with a thin layer on the bustal planes bed of camshafts. Too thick layer in the clamp of parts will result in the extrusion of the sealant inside the GBC, which may cause the lubricant system lubrication. After installing the valve cover, the internal joints in the candlestone also recommend losing with a gasket sealant.

Sealing threaded connections

Getting trash, foreign items in the engine cylinders, cylinder head, can lead to a decrease in the resource and a serious breakage. Therefore, perform all work as much as possible.

Usually, machine oil in the candlestones does not cause special concerns from motorists. But statistics says, in most cases, there are reasons to fear for stable work Engine, because oil in the candlestones should not be.
There are some possible causes Why oil falls into the candlestones, and several nuances can affect it, which should be considered separately. In order not to take the car to the maintenance station, you can try to solve this problem without resorting to the services of specialists.
To do this, you must first determine why oil fell not by purpose. If suddenly it was discovered that car candlestones in oil, then immediately need to track the reason to turn the negative consequences.

As a rule, this problem occurs more often in old cars than in new ones. If the candles in the oil, the reasons for this may be related to the fact that the most suffer the car that have quite large mileage. If, when replacing candles or during their revisions, traces of oil were found, then this is most likely indicative of the deplorable state of the gaskets that were worn out.

Old cars, as a rule, require a replacement of a large number of laying elements, not only the pads under candles, and although some motorists believe that it is possible to exploit the car in such a state, the practice still shows that problems with gaskets need to be solved as quickly as possible, otherwise it is will affect the service life of the entire car system as a whole.

Subsequently, the presence of oil in the candlestones can lead to the fact that the insulation of high-voltage wires, which usually consists of rubber, softened or will be squeezed by additives, and perhaps even the base of the oil (if insulation is poor quality), which besides pollution of wires, can also lead to closure electrocups.

In this case, the current breaks may damage other devices of the car, which besides unpleasant blows, electric current also threatens with the refusal of some systems, including electrified or those, the functioning of which depends on fluids inside. In addition, the problem may be aggravated by the fact that the candles themselves will become unsuitable, and their service life can be reduced. Therefore, the oil caught under the candles will not only force the driver of the gasket, but can also lead to a constant need to replace the candles. To avoid this, you need to prevent further oil entering the candles.

How to remove the leakage of oil into candlestones?

In order to independently prevent the oil from entering the candle, there will be several elements. Further repair is reviewed by the example car Lada. Priora.

First, you need to stock up with multiple gaskets for valve covers and seals. It will also be necessary to use lubricant, like the VD-40, the engine cleaner and the glands. For candlestones, the repair should always be carried out in a room with normal temperature conditions - without drafts and winds, to prevent dust and other pollutants from entering the working surfaces.

There are several major alternate steps of repair:

1. First you need to remove the valve cover, Receiver. The collector needs to be covered, as well as isolate all holes to prevent foreign parts and contamination into the node.

2. After you need to remove the ignition and dismantle the crankcase ventilation tube. Then you should unscrew the bracket under the nozzle and remove the block cover.

3. It is worth checking the hydrotrode, pressing on him, - he must come with normal effort. The camshaft fist should be directed to the rear.

The collection of the system occurs in the opposite algorithm, while the old sealants and lubricating fluids should be removed from the bearing case, and the shaft fists need to be lubricated with fresh lubricant.

It is worth noting that in the absence of experience of such repairs, you should not try to spend it yourself, especially if there are no skills of the tools.

In this case, it is necessary to contact the nearest car service, where such manipulations will spend literally in a few hours, but they guarantee excellent repair quality.

Thus, the car will serve for a long time to serve its owner, spark plugs and gaskets in wells will not need to change too often.

Most likely, the volume of oil falls into candlestones is threatened, most drivers and experienced, and newcomers are unlikely. And completely in vain. The causes of this phenomenon can be various factors. In many respects they depend on the engine model, and from its type.

In any case, the wedding owner will most likely not rush to break his head on the nearest service station, but try to solve the problem independently. So let's stop in this in more detail.

What threatens the fall oil into the candlestones? A similar trouble may happen quite often, especially on cars domestic production, with decent mileage. We will analyze the elimination of the problem on the example of the Lada Priors, the car of the domestic release of the vase, not without some of the shortcomings.

Possible consequences?

The main reason for the appearance of oil in the bellows of the candles is the wear of the gaskets. And what may be its consequences for the health of your car? In fact, to be honest, such a fiery in operation can not lead to a particularly military lead, according to experienced repairs. That is, you can ride with such a problem, but not too long. This is not to enter the same specified lubricant on the GBC (head of the cylinder block).

One of possible consequences It is the case when the rubber insulator of wires (high-voltage) is softened, which can cause and breakage the electrical circuit. However, the fact that the breakdown is insignificant, should not mean her launcher on Samotek (many people like to ride until everything closes and will not start falling off). And if you notice that the lubricant is lubricant in the candlestone, laying this node must be changed as quickly as possible. So the problem will be eliminated, and the question is resolved.

Still masters notedWith this scenario, it is necessary to change the candles themselves quite often. Their resource is significantly reduced (several times, by experience). And if you do not want to get out and put new with enviable constancy, it is necessary to do appropriate repair work.

Repairs

How to work out the change of these parts right? At first, for a successful procedure, you must prepare the appropriate details and tools. We will need: a pair of valve cover pads, 10-sealing, cleaner for the engine, 4th seals for wells. Collect the listed, you can start. The process is better to produce in a closed heated and illuminated room, as a last resort, in a closed from the wind and dust (because the dust can get into unprotected sites of the node, creating additional problems).

We produce work in several stages:

• Remove the valve cover, also - receiver. In the collector, we close all possible holes so that unnecessary details, items and dust will be in the node itself;
• Unmount the ignition, hose;
• We unscrew the bracket bolt on the nozzle (key 10). Then - screws on the lid of the block (15 pieces). Remove the cover;
• Next - you can check the hydrotroller. It's quite simple: with a screwdriver. You need to click (it should be squeezed with good effort). In the opposite case, the mechanism is changed. With such diagnostics, you carefully take care of the camshaft camshaft to be directed by the back side;
• After you need to dismantle the candle wells. This procedure is done using the appropriate puller. It must be inserted into the well well, the nut is delayed and the mechanism is quite easily dismantled;
• Next, remove the old sealing rings and install new ones;
• We collect all B. reverse order. Remember that before assembling the head should be carefully cleaned from dirt and the bearing case - from old sealants and oil. Fist shafts need to be launched with fresh lubricant. Before mounting the housing, we apply a sealant to the places where it was before dismantling.

The car engine is a combination of a large number of systems and nodes that work for one general result. Despite this, the intervention of one system in "life" another can lead to a malfunction of both and even to disable the entire power unit.

To insulate individual systems, the manufacturer includes various glands and gaskets that compact and seal the compounds and do not allow mixing liquids and gases. However, due to the fact that the motor constantly works in heavy conditions and exposed to high loads, gaskets and glands often come into disrepair, resulting in tightness in a particular system.

Today, dear friends, tell you why oil penetrates the candlestones and what is fraught with the engine. Also briefly let's talk about how to solve this problem.

Oil leakage is always bad, not only in terms of oil consumption and its cost. Different oil leaks often lead to the formation of a car in different parts of the engine, unstable work The power unit, as well as the occurrence of a thick layer of dirt on the motor hull.

In the Candle Well Fords - the phenomenon is quite common, but this does not mean that other cars are completely deprived of such "sores". And you can see oil in the candlestones not only on cars with big mileage, Often even new cars from the conveyor have such an unpleasant defect. This was due to the fact that during the assembly, the sealant simply did not have time to grab or was simply poor-quality. If it is not possible to eliminate this problem in a timely manner, it may damage the spark plugs in the process of ignition, coils, as well as the unstable operation of the engine. The most common problem after the oil falls into the candlestones - the sample of sparks and skipping in the cylinders. The engine begins to lose power, troit and works with interruptions.

Why is this happening?

Fitting oil into candle wells occurs through leaks in the valve lid. It may be a poor-quality gasket or sealant, a problem with the glands of the wells, a bad tightening or violation of the assembly rules. Most often, the leak gives the connection exclusively on sealant, which during operation is subjected to constant heat loads, from which it can be deformed and dried. As a result, leaks and oil penetrates the candlestones.

Elimination of the problem of oil in the candlestones

This work provides for dismantling: intake manifold, timing belt casing, valve cover. After receiving the necessary access to the workplace, clean the joint from the remains of the laying and the old sealant. It is necessary to work carefully using wooden or plastic scrapers, metal analogues are able to leave scratches that will inevitably lead to the emergence of new problems associated with depressurization. There is also a lot of specials on sale. Chemistry, which without any problems removes any sealant. After everything is degreased and a new layer of sealant is applied to the joint. The assembly is performed in reverse sequence, the bolts are delayed with a dynamometric key.

In general, the process of replacing the gasket or sealant of the valve cover does not represent anything complicated, the most important thing in this process correctly remove the old sealant and put a new one. Also, an important role is played by the tightening of the bolts, the wrong effort can be reduced to no all your efforts.

After completion, it is necessary or at least to check and clean the old candles.

If everything is done correctly, oil in the Ford Candle Welcome You will no longer see. If, after repair, the oil falls into candle collectors again, I recommend contacting the specialists who will be able to perform better and efficient repairs.

I have everything, thanks for your attention to the new meetings. So far, write in the comments for what features you found oil in the wells of candles and how you solved this problem.
