How oil falls in candlestones. Why oil appears in the rubble and what to do to eliminate it. Consequences of oil entering candlestones

the main / miscellanea

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, your own hands carefully make sure the cam distribution Vala. was 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 everything in the 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 lubrication. Before mounting the housing, we apply a sealant to the places where it was before dismantling.

It is well known that the engine and its systems have various seals and gaskets in their design, which provide the necessary seal in the connecting places of individual parts and elements. Such a seal allows sealing joints, which eliminates the course and other technical fluids.

At the same time, during the operation of the car, the owner often may often face the fact that the oil still begins to leak. In some cases, the lubricant actively pollutes the engine outside, the oil falls into the candlestones, follows from under oil filter, flow, etc.

It is important to understand that oil leaks not only lead to increased flow lubricant And pollute, but are the cause of various failures, that is, affect the operation of the motor. One of these common problems is considered to be the problem when oil is detected in candle wells. Next, we will talk about what the cause of oil getting into the candlestones, as well as how to eliminate such a flow with your own hands.

Oil in Candle Wells: Cause of Malfunction and Possible Consequences

Note that the appearance of oil in the area of \u200b\u200bthe candlestone is sufficiently distributed on different internal combustion systems. Next, we consider the problem on the example of 16-valve motors, which are installed on the domestic model of Lada Priora.

It should be added separately that such a problem may occur both on a car with mileage and practically new copies. In this case, this malfunction should be immediately immediate, as the oil entering the wells can lead to more serious complications.

In the event that the oil is present in the candlestone, then this leads to the softening of rubber elements (insulator,). As a result, sparklers arise, ignition passing over the cylinders, the engine is badly started, the troit, loses its power. In the future, various elements (coil, candles, etc.) may fail.

Such failures can cause the fact that dashboard , the motor becomes necessary to constant, not to mention the reduced resource of the candles themselves, wire of wires and other details.

So, back to the reasons. Let's start with the fact that the oil usually enters the candlestones through looseness in the area of \u200b\u200bthe valve cover or through the glands of the candlestones. On many engines under the valve cover for sealing, a rubber gasket is installed, also recently received widespread distribution different types Sealants (anaerobic, silicone, etc.).

Often, oil leaks are found on the engine, where the valve cover is initially planted only for sealant. In other words, constructively installing the gasket from the rubber is not provided by the manufacturer itself in order to simplify and reduce the cost of the overall design.

The gradual drying of the sealant, errors in its application, as well as the use of low-quality compositions leads to the fact that such a seal begins to flow, and much faster compared to the usual laying. The owners of the models of the prior noted the cases when oil in the bellows of candles appeared even on new cars. The fact is that during the long downtime of the car in the car dealership, the sealant managed to try simply.

Self elimination of oil leaks in candlestones

Taking into account the above information it becomes clear that for normal operation of the ignition system, even a minor leakage, which leads to a cluster of oil in the field of wells, it is necessary to eliminate. At the same time, not all drivers know what to do if oil in the candlestones. Let's look at how to remove the oil from the candlestones and make such a repair with your own hands.

Immediately note that although this procedure is not difficult, without certain skills, it will still be correct to contact the service and entrust the car to the specialists. If you decide this problem yourself, then you will need:

remove the intake manifold;
dismantle the casing;
remove the timing belt;
remove valve cover;
take out of bed;

These works will allow you to get free access and fully remove the old layer of sealant from the elements and surfaces, and also qualitatively apply fresh composition. Note that it is necessary to completely remove the old sealant. Any residues can disrupt the subsequent sealing of parts with the help of a new composition. In this case, the whole complex of work is needed to venture.

At the same time, it is necessary to remove the old layer of sealant, that is, it is impossible to use sharp solid objects or abrasives. The fact is that the appearance of scratches and scratches on the bustal surfaces can lead to the fact that even after applying fresh sealant, it will not be possible to achieve tightness after connecting parts.

As a result, oil leakage will continue, additional air seats may appear, etc. For this reason, the old sealant is removed by solvent chemicals. This uses acetone, White spirit or ordinary gasoline. A small piece of fabric is wetted in a solvent, after which the surface is thoroughly rubbed from the old sealing composition.

Then fresh sealant is applied to the surface of the valve cover, after which the reverse assembly is carried out. As for the sealant itself, for these purposes optimal option It is anaerobic sealant. During the assembly, it is also important to take into account the order and moment of tightening the fastening bolts when the valve cover is installed.

As can be seen, the replacement of the sealant under the valve lid is not a complex procedure. The main requirements can be considered a thorough cleaning of the old layer and the proper application of fresh sealant to the surface.

The applied layer must be smooth, interruption is not allowed. It should also be noted that the composition for sealing needs to be treated and joints between compounds of candle wells, pre-removing from there an old sealant.

We add that the specified areas are usually abundantly covered with a sealing composition, which will require certain efforts to complete the cleaning of such surfaces. To process compounds of candle wells, a special red sealant is used, which can be purchased in auto shops.

It should be noted that the use of the sealant if the valve cover on a particular engine is installed through the rubber gasket, is undesirable. In this case, you must purchase a new high-quality gasket, after which the valve surfaces are checked. Next, after which the valve lid is tightened with the order and torque of fasteners.

That in the end

As a rule, it is possible to solve the problem of oil in the candlestones with minimal financial costs. Even if you acquire an expensive professional sealant, the price of a small tube remains quite affordable.

After removing the oil from the wells to restore the normal operation of the engine, it may also be necessary to replace the spark plugs and high voltage wires. The reason may be that the oil in the wells quickly softens and damages rubber insulation.

We add that at the initial stage, in some cases, it is not necessary to change the candles, but it may be necessary to produce. Only after removing pollution and nagar force aggregate It will work stably and smoothly.
If errors were allowed in the process of applying sealant, then oil leakage can be maintained in the future. For example, anaerobic sealants solidify only when there is no contact with air. It turns out if it fails to achieve a dense fit of the surfaces, then the composition will remain liquid and seam sealing will not occur.

Why occurs to leak oils in the scene boards of the sixteenth glove engine on Lada Granta: causes and consequences

The origins of the problem take roots from the first 1.6 16V, which was mounted on "dozens". According to the results of the first two or three years of operation, the VAZ 21124 engine demanded serious interference in view of the fact that the candles were filled with oil suite. The case is certainly a warranty - a malfunction was eliminated for free in the dealer center, as well as now. However, no one has given the guarantees of the absence of repeating symptoms in the near future, and not going to give.

Where emulsion come from

The oil in the candlestone is accumulated on the grant 16 of the valves for one reason - the loose contact of the conjugate parts of the cylinder block. After driving the coil, you can see two junctions on the plane:

Valve cover bed camshafts.
Cover of switchgear GBC.

The gaskets do not apply on the sixteenthlylaps. The docking surfaces are compacted by special sealants. At the factory, they are applied by spraying and dry over time. Through the looseness, the oil emulsion begins to leak, which goes into the wells and outwards (the engine sweats).

What threatens the filling of the well oil

Strog under the hood is fraught. At least the candle in the oil suite is subject to failure, as a maximum - can "cover" an expensive ignition coil. It is not necessary to assess the situation exclusively in the monetable key - such an environment under the engine cover is unsafe in terms of the emergence of a fire.

Diagnosis of malfunction

In the early stages, only the direct fixation of the fact of finding the oil in the candle flux will be discovered. To do this, it is enough to dismantle the ignition coil and evaluate the space around the candle. In the launched cases, the following status symptoms will indicate power plant:

Skip ignition.
Troy.
Lowering the oil level.

For your information. Most often, the disease overtakes the fourth cylinder. It is exposed to a high temperature gradient, especially in winter.

How to eliminate oil flow in a candle well on the Lada grant with a motor on 16 valves: a sequence of actions

Without a thorough inspection, succeed in the elimination of the defect will not work. His task is to find out which of the two joints of the GBC flows. This depends on the specificity of the outflow technology. Often, drums are observed only from under the valve cover, eliminate which is much easier than the leakage of the oil-emulsion at the junction of the bed of camshafts and the head of the cylinder block.

Selecting sealant

Eliminate leaks of oils in grant's candle wells can be only one way - "plant" parts of the GBC on a special anaerobic sealant. The secret of the sealing mixture is that it is instantly hardening in the absence of contact with air. Such a condition is created in small gaps between parts of the cylinder head.

Part of the hermetic composition remaining outside and inside the engine is in contact with air, and therefore does not harm. Under high pressure The oil flies the liquid remnants of sealant with ribs and safely displays them through a small network of oil canals. That is why it is so important that an anaerobic sealing mixture is so important - it will not forget the maslochannels and hydrocompensators, in contrast to the conventional seal, hardening in the air.

For your information.

Color - red.
Packaging - a syringe, which is enough for the processing of a single connection, say, the valve cover-bed camshaft.
Approximate price for 1 pc. - 200 rubles.

Preparatory activities

Get to the valve cover, like , not so easy. It is necessary to dismantle the throttle assembly with the inlet nozzle and receiver. Removing the intake manifold is associated with a number of difficulties: the back of the engine will have to be disconnected from the support (pillows), since the places in the subcontrol space are noticeably less than that of priors.

If it flows from-under bed, you will have to additionally shoot:

Timing belt.
Switching shaft gears.
Camshaft bed.
Trees timing.

It is possible to remove the oil from the luminous wells of the Lada Grant Lada Motor on 16 valves by sealing all the joints with airtual composition. Before applying a viscous consistency, the surface is pre-cleaned from the factory layer with screwdrivers (screwdriver, chisel, knife blade) and degreases. Apply the sealant is necessary for one of the conjugated surfaces. Successful sealing is possible only after processing all the joints of the GBC parts specified in the figure.

Reverse assembly

Making camshafts are not more difficult than , the main thing is not to confuse them. Overall characteristics The same, but there is an additional groove on the inlet camshaft. With troubleshooting, it is advisable to connect the replacement supplies, such as:

Seals camshaft - 250 rubles per 2 pcs.
The plugs of the camshaft - 100 rubles for 2 pcs.
Carter ventilation nozzles - 250 rubles per set (3 pcs).
Seal oil affection - 30 rubles per 1 pc.

The glands and plugs are preferably "put" on the sealant. Installation work The bed of camshafts and the valve cover is recommended to be performed using a dynamometric key, otherwise the risk of threading threads or break the bolt is great. Tightening threaded connections is conducted in accordance with the scheme in compliance with the moments:

Bed camshafts - 12 nm.
The valve cover is 5 nm (by manual, some motorists are tightened with a moment of 10 nm).

Summary

The causes of the leaks of oil into the Sixteenth glovental power plants of the Lada Grant is a loose connection of the valve cover with the camshafts and / or covers of the camshaft with the GBC. The fault enhances the level of fire danger and leads to the failure of the ignition coil and candles.

Prevent the leakage helps the processing of joints of the conjugated parts of the cylinder head of the anaerobic sealant. To apply a hermetic composition, it is necessary to dismantle the parts and prepare the surfaces. For back assembly Be sure to replace the receiver gaskets and use the dynamometric key.

It is necessary to deal with the oil in the Candle Weld of the VAZ 2110, it is necessary after the main thing was understood. The reason for this factor may be different, it also depends to some extent on the types of engines.
On the VAZ 2110, the oil in the candlestones can lead to unpleasant consequences.

The consequences of the appearance of oil

What could be the consequences if you do not pay attention to it on time?
When the car is operating with such a defect, there is a breakdown of high-voltage wires, due to the softening of the rubber insulator. Also, the candlelight will occur premature Nagar, so they will not produce their service life. This leads to a frequent replacement.

Engine designs on VAZ-2110 are constantly being improved. Therefore, on some engines, such as 1.5 liters are installed guide tubes - glasses.
Motors with a volume of 1.6 liters are not equipped with glasses, candlestones are provided in the design.
You can identify it yourself:

Unscrew the candle.
View visually nest.
If glasses are installed, then the surface is smooth to the top of the well.
In the absence of it in the well, two slots are visible.

Engine 1.6 L.

Engine design 1.6 l more modified option. On such engines, the appearance of oil in the well can be formed due to poor seal.
You can try to start to stretch it, nuts on the heads of the head can be loosen:

To perform this work, you will need head No. 8.
Tightening should be done, alternating nuts right side and left.

Rafting wipe the seats of all candles. Try a machine to operate.
The oil continues to enter the slots of the candles, it means it is necessary to replace the sealant layer on the cover seal.
To do this, it is necessary to buy an anaerobic sealant in the auto shop:

Put a car into the garage room.
Disconnect the minus terminal with the battery.

Prepare a tool:

head number 8;
horn key number 10, №13;
a screwdriver with two nozzles - flat, cruciform;
a sharp knife.

The order of work on the tightening:

Press the plastic lock.
Disconnect the coils from the coils of the wiring harness.

Unscrew the bolt that crept the coil to the block cover.
Remove the coil from the candle well.
In the same method, disconnect the harnesses of the nozzles of the nozzles from the front bracket. Rozhkov key number 10 unscrew the front bolts, rear brackets.
Loosen the screws on the clamps of the exhaust hoses of the crankcase ventilation, from the nozzles of the cover and the cylinder block.
Remove them.

The oil level indicator (probe) is installed on the guide bracket, so you need to unscrew the screw of its attachment.

Remove the guide assembly with the pointer.

The intake manifold is fastened to the lid with two nuts, unscrewed by their horn key number 10.
To the head of the block, the collector is fastened with three nuts No. 13 and two bolts, unscrewed by the root key:

Remove the collector after that.
Head number 8 Unscrew the nuts with the spills of the lid.

Neatly flat screwdriver squeeze the cover from the block while holding the protrusions around the perimeter:

Remove it.
Put on the workbench.

FROM inner, flat screwdriver gently clean from the old sealant. Moisten a rag in a solvent degreased sealant application.
The inner surface of the cover will also wipe the closure. The glitterness of the block is to clean from the applied old sealant, degrease the solvent.

Note: Do not conduct gasoline degreasing, as oil additives are present in its composition.

After cleaning work, a thin layer pave a sealant along the edge of the unit:

Put the lid.

Screen nuts are necessary in order, installed assembly technology.

1.5 l engine

The oil in the candlestone can accumulate due to damage to the seals (seals), which are installed in the wells themselves. In each well, the glands are installed on top and bottom of the glass (2 pcs.).
Buy the glands are necessary after their inspection. It is necessary to make sure that they do not have cuts, cracks, growths.
The rubber gland must be removed by glossy glitter.

Replacement of salon

To replace the seals, it is necessary to remove the valve cover, the work on its removal is described above. It is necessary to produce the process of removing wells with two flat screwdrivers.
At the top of the wells there is a protrusion in which screwdrivers are resting, from two opposite sides:

Gently simultaneously pressing the screwdriver with the same effort, remove the glasses.

Warning: carefully remove glasses, do not allow the lower sealing ring to fall into the camshaft bearings housing.

With dismantled glasses, clean the traces of sealant, wipe the winds of the accumulated mud around the circumference of the wells:

Install purchased glands inside wells, lubricate them motor Oil.
The installation of the well must be carried out with accuracy.

The fixation of the well is made by the collar, which is in the design of the upper ring of the bearing cover.
Therefore, further work on its installation should be carried out using head No. 22:

Install it at the edges of the well, press up to the appearance of clicking.
This will mean that the well snaps into a collar.

Replacing the seals in wells can be carried out without removing the valve cover. For this you need to make the puller with your own hands.
Materials for its manufacture:

stud in length 14 cm;
rubber hose with a diameter of 25 mm;
two metal washers by the outer diameter of the candlestone;
sleeve;
nuts in the amount of 3 pieces.

On the hairpin in the sequence to wear:

puck
rubber hose,
puck
sleeve
nut.

The bottom washer is focused on the tip of the stud, the top washer is clamped by a sleeve:

insert a manufactured puller in the well,
tighten the bottom nut until the well can be removed during the axial movement.
attach a little effort and a glass is removed.

ATTENTION: The attached friction force allows removing the puller with a cladding well. WARNING: It is necessary to take into account the elastic member inserted into the glass should not look out for the edges of the candlestone!

By the same principle, work is carried out on the installation of new seals along with glasses:

Before installing, it is necessary to lubricate them with engine oil.

Note: A gum of the puller should not stand for the edge of the well, otherwise the nuts twist will give it the edges, which will not give the desired effect.

Show accuracy when removing a candle well, do not allow to jump apart the old lower coil.
Working work with your own hands will make savings of financial resources of 1500 rubles. This is the initial price for carrying out similar repairs in the auto repair shop.

The cost of the glands is 100 rubles. For one set.
The price of anaerobic sealant is about 700 rubles.

Repair to remove the reasons that enhate the appearance of oil in the candlestone on the VAZ-2110 can be started after watching the video and attentive study of the photo on which all venues are indicated. repair work. It is also necessary to familiarize yourself with the instructions for applying the necessary precautions.

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 ignition skipping in the cylinders on the dashboard, check Engine will light up.

It leads to such consequences, the negative impact of motor oil on the tip seal of high-voltage wires, modules of ignition coils. 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. The bottom gland needs to be lubricated with engine 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 COF MODEL 21126 It is necessary to remove not only the 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

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.
