Why oil falls into a candle well. Where to flow oil into candlestones on a grant and how to eliminate it. How to replace this detail

Each brand and model of the car has its own distinctive features. For example, the Vazovskaya dozen very often suffers from the fact that it candleys Often "bathe" in the oil after some 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 the candlestones, it 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. It is easier to divide this process to 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. The principle of ventilation of a closed type crankcase implies a supply of a mixture of oil vapor, gasoline and exhaust gas back into 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, oil in the air filter, candlestones, we strongly recommend checking the crankcase ventilation. 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 does not fix the cause of oils on time, the engine will start tall, loses its power in all or certain modes of operation, which can also be poured into big flow Fuel. Most likely, due to the ignitions in 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 Lada Priora, Kalina, grant with internal combustion engine Models 21126 It is necessary to shoot not only hinged equipment and valve cover, but also gears of camshafts, 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

On Toyota cars and other cars with a similar type of device, the repair is to lubricate the bottom and the upper thread. For the removal and subsequent installation of the tube, you need to screw and consume two nuts. It is also necessary to replace the cuffs that seal the jack of insertion of the wells and the valve cover. Detailed instructions for removal hinged equipment, Moments of tightening, you can find in the repair manual and operating your car model. We offer to watch the video of repair.

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.

If the oil appears in the candlestones on the 16-valve VAZ-2112, then you need to pay for it special attentionSince this can lead to breakdowns of high-voltage wires, as well as other problems associated with the work and normal operation of the engine. In this article, consider how to determine the problem and methods to eliminate it.

Consequences of oil entering candlestones

Oil in a candlestone

When oil appears in the candle wells, a nagar will appear on the ignition candle, the high-voltage wires will be made through, or or.

It is so structurally so it happened that only 16-valve engines with a volume of 1.6 liters are equipped with candlestones. For 1.5 motor installed guide tubes - glasses that are missing on the older fellow. This can be determined very simple:

• Unscrew the candle.
• We visually inspect the nest.
• If the surface is smooth, glasses are installed, and if there are slots - then the candlestones.

1. Bad valve cover seal.
2. Valve glands damaged.
3. Sealing compounds of candlestones were worn.

When all possible problems Considered, you need to go to the methods of solution.

Methods of solution

Engine with a valve lid, where candlestones are visible

To eliminate oil in candlestones, it is necessary to gradually consider each problem. For each reason, a different tool and time will be required.

Bad valve cover seal

To eliminate this problem will be required. Using the head on 8, we carry out a phased tightening of each nut until the maximum seal is achieved. Then, it is necessary to rub the candlestones with a vet.

Valve lid tightening sequence

We collect everything back and drive a few kilometers. If the effect is disappeared, the problem was in the seal. But it is worth watching the condition of the candlestones and the presence of oils in them. If it appears again, then you need to look for the cause elsewhere.

Damage to valve glands damaged

With greater wear masonry Capscan appear oil in candlestones. This is due to the fact that the glands do not completely remove the oil, and it hits the candles and in the wells. To resolve the problem, it is necessary. If the candles have a large nagar, then it is necessary to check and in the case. About, .

Wear of candlestone seals

To eliminate this problem, you will need to replace the seals. Usually they are sold by repair kits. The cost is on average - 400 rubles.

Remkomplekt Candle Wells Production AvtoVAZ

Consider, step by step, how to install a repair kit for candlestones. But, first, you need to decide on the details: laying the valve lid and repair kit for candlestones. Now, directly the process itself:

1. We carry out the valve cover dismantling.
2. Insert a special puller inside the candlestone.
3. Spin the fixation nut.
4. We take out the well.
5. Remove seals.
6. The assembly is carried out in the reverse order.

And here are two grooves, marked by the arrow

When the repair kit is installed, all possible oils in the candlestone are eliminated, and therefore you can ride further.

conclusions

Find the cause of oil in the Candle Wells of the 16-Valve Engine VAZ-2112 is quite simple. You can eliminate it yourself, but not always and some car enthusiasts often turn into a car service.

The main places where you can meet with leakage:

• wells (containers) of candles;
• region next to the oil filter;
• selniki. crankshaft or camshaft.

Oil leakage is not just the problem of engine pollution (although this fact does not have a positive effect on the overall state of your Iron Horse). The reduced level of oil, as is known, extremely negatively affects the operation of the engine, while significantly accelerates its wear component parts. We strongly recommend periodically checking the oil level using a special probe. This will help you to prevent leakage on time, as well as start the process of identifying the problem.

One of the most common problems - the oil falls into the candlestones. Let's figure it out with the reasons for its occurrence, as well as define a way to deal with a malfunction.

How to check whether oil happens?

The verification process is quite simple. It is enough to remove the candles, and then with the help of a flashlight to explore the cavity, where every candle is placed (a candle well). Usually leak oil takes place only in 1-2 wells.

Cause of oil hits in candlestones

Root problems go to malfunction from the pads of the valves. It is also possible to malfunction in the glands of the candle wells. In a word, any source of oil ingress implies problems with rubber gasket or a sealing agent.

Often, the rubber gasket may not even be used by the manufacturer. This is done in order to simplify production, as well as minimizing the cost of parts. Of course, the absence of gasket (use only sealant) negatively affects the reliability of the compounds.

It should be noted that the large mileage of the car is far from always acting as a catalyst of the wear or incorrect functioning of the gaskets. The problem with filling the candlestones is often found quite often on vehicles without a run or with a minimum number of kilometers traveled.

What threatens the oil in the candlestones

Eliminate the problem must be immediately as soon as you discovered it. This question does not tolerate deposits. Riding on vehicle With a similar malfunction entails the appearance of many more serious problems. Some of them:

• weakening of insulators (in high-voltage wires, ignition candles);
• failure of spark plugs and coils;
• engine power loss;
• periodic breakdowns sparks.

In addition, minor troubles are possible: the engine can start tangible worse. This is especially noticeable in the winter.

As a consequence of the faults mentioned above, the indicator lights up Check Engine" The car owner is forced to spend time and means to diagnose the engine, as well as reset mistakes. The consequence of the "flooding" of the candlestones is to accelerate the wear of high-voltage wires and the candles themselves.

How to remove oil from candlestones?

So, you decided to overcome a malfunction to get rid of the leaks of the oil. First of all, it is worth saying that this procedure is quite simple, but without any experience of repair and interaction with the "insides" of the car, it is better for it to still not be taken (contact the nearest car service).

If the experience is still there (or there is a great desire to do everything with your own hands), we propose to do on the following algorithm:

• dismantle the intake manifold;
• prepare everything for removing the timing belt (dismantle the casing);
• remove the timing belt itself (by the way, it is recommended to inspect the wear belt at the same time) and the valve cover;
• remove the camshaft.

Then you can freely get to all places where you need to replace the sealant. Previously, naturally, it is necessary to remove the old layer of the sealing agent, and then thoroughly clean the surface. If necessary, you can also process all the problem areas with solvent (White Spirit, for example, perfectly cope with this task).

To stripping parts from the old sealant, it is necessary to approach the most responsible as possible, since any (even the most insignificant) remains of the old substance can cause sealing disorders with a new composition. In this case, you will be forced to reinstall all work on disassembling, stripping and repair. In addition, the proportion of the material will be wasted.

To remove the old layer of the sealing agent, it is recommended to use gentle materials. Do not use abrasives (for example, rigid sandpaper) or files. Such tools can leave scratches and chips that often serve as the reason for the depressurization of the compounds in the future. As a result, a new oil leak appears, pulling up air and repetition of all repairs.

Loosen the old sealing agent can be a simple solvent or gasoline. It is enough to moisten a cloth in the liquid, and then without extra effort to treat the surface.

In addition to all measures to seal the compounds, the ultimate, it is necessary to remove the oil from the candlestone. There are no difficulties in this process. It is enough easy to get a candle well with rags or sponges. You will completely bypass with infirred materials without the need to use some special tools.

Fully cleaning the candle well from the oil, you can install the candles backwards. Before installing, make sure that the candles from the wells, where oil leakage was observed, do not have a car, are in good condition. Otherwise, candles are subject to immediate replacement (do not try to continue to use them).

Applying a new sealant layer, be careful, because it should be smooth. Significant deviations from the optimal amount of sealing agent in any direction may cause further problems. Candle wells are usually processed by a special red sealant (it is easy to find in auto shops or on automotive market Your city).

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.
