Air filter pipe for VAZ 2110 8 valves injector

The air filter is an important consumable component that protects key engine components from dirt, dust, stones, insects and other debris that can harm the stable operation of the engine. The air filter should be changed every 10-15 thousand kilometers, or in accordance with the manufacturer's recommendations.

When replacing, the driver may encounter the problem that traces of engine oil appear on the filter element. In some situations, the driver pays attention to this due to symptoms of improper operation of the air filter, which has not yet completed its required mileage. It is prohibited to operate a filter that contains traces of engine oil for reasons of safety of the car engine. At the same time, installing a new filter element will not get rid of the problem, since after a few kilometers of run oil traces will appear on it. Before changing an air filter that has traces of oil on it, you should find the problem and fix it.

Reasons for the appearance and methods of eliminating the appearance of oil in the air filter and corrugation of VAZ cars

When operating VAZ-2110, 2114, 2115, owners are faced with the problem of engine oil appearing in the air filter and corrugation. This happens in 8-valve and 16-valve engines. As a result, the air filter clogs prematurely and loses the required capacity, and this leads to a change in the parameters of the fuel-air mixture. The car's power decreases, and the engine wears out more intensely. Often the appearance of oil in the air filter and bellows leads to failure of the mass air flow sensor, which will require its replacement.

What to do if oil gets into the filter

If the problem is not related to a dirty air filter, you will need to carry out several diagnostic procedures to determine the problem and then eliminate it. You can determine the cause of engine oil getting into the air filter as follows:

Check the exhaust color . If bluish-blue smoke comes out of the exhaust pipe of a car, the malfunction is associated with wear of the elements of the engine cylinder-piston group;
Measure the compression in the engine cylinders . When the measurements are taken, you need to compare them with the normal values for a particular engine, which can be found in the technical reference book for the car. If you cannot find normal compression values, you can stick to average numbers - from 9 to 12 atmospheres in each cylinder. Important: The values in different cylinders should not differ by more than 1 atmosphere, otherwise this can be considered a malfunction. When the measured pressure is less than expected, this indicates an engine malfunction. Most likely the problem is due to poor fit, damage or wear of the rings. It is possible that the valves have burned out or another problem has arisen in the operation of the motor;

Reasons for the appearance of oil in the air supply system

To make sure that the engine is throwing oil into the air filter of the VAZ-2110, 2114, 2115, it is enough to disconnect the corrugation, in which you can see oil splashes and drips. Sometimes when replacing a filter you can see that it is not just dirty, but saturated with machine oil. To identify the cause of oil getting into the air filter, you need to completely remove the pipe so that it does not interfere with operation, for which you need to loosen the clamp and disconnect it from the throttle valve.

This will open a tube above the throttle valve with a hose connecting it to the valve cover, where excess oil is supplied. You need to remove the rubber tube from the valve cover and try to blow it out. If the throttle tube is not blown through, it means the system is clogged, and this is the reason for the appearance of oil in the corrugation and air filter. This situation is due to the fact that the oil does not return to the cylinder block through a rubber hose, but is discharged under pressure into the air supply system, first of all into the corrugation, and then to the air filter.

Much less often, squeezing oil into the air filter bellows indicates severe wear of the piston group, in which case a major engine overhaul will be required, but more often the problem lies in the obstruction of the throttle valve tube described above. It happens that the rings on the pistons have already come together in a row, they leak oil, and the engine requires serious repairs, while no traces of engine oil are observed on the air filter and in the bellows, they are absolutely clean.

The role of pipes in the VAZ stove

The heating system in the car operates automatically, thanks to which the air enters the cabin at the required temperature with an error of about 2 degrees. To connect various elements to each other, where the working fluid is present, pipes are used. Experts recommend that VAZ 2110-2112 owners pay special attention to the pipes and monitor their condition.

Defects that are not corrected in time may subsequently affect the operation of the car engine. It is also important to monitor the condition of the clamps that are responsible for the tightness.

The lower pipe serves as a supply of coolant to the radiator. Hot coolant flows here.
The upper pipe plays a draining role; the cooled liquid leaves the heater radiator.
Short couplings are required for the pump and thermostat.

If faulty pipes or coolant leaks are detected on a VAZ 2110-2112, professionals recommend immediately replacing the faulty elements.

How to prevent oil from getting into the air filter

The simplest solution is to simply break through the clogged tube using soft wire with a diameter of 0.8 mm. But since the entrance to this tube is angled, you need to act very carefully, in addition, this does not always lead to successful cleaning of the tube. When the connector is cleaned with wire, you need to try to blow out the tube again; if air flow is restored, oil will no longer get into the air line.

You need to blow through the throttle tube through a rubber hose; this can be done with your mouth, using a special syringe or a hand pump, which will help create sufficient pressure. When the pipe is cleaned, air passes freely, and oil will not enter the engine air supply system, being discharged into the cylinder block; the bellows and filter will remain dry and operate normally.

Cleaning the throttle body

If it was not possible to pierce the tube with wire, you need to completely dismantle the throttle valve. This is done as follows:

the pipes approaching the damper from above are removed;
the latch is removed and the cable controlling the gas is removed;
the electronic throttle position sensor is disconnected;
unscrew 2 13 nuts securing the damper (one higher, the other lower).

The throttle valve is easily removed from the engine block, after which it needs to be cleaned. This does not require additional equipment and tools; all work can be done in a regular garage.

To clean the throttle valve, we take the same wire with a diameter of 0.8 mm and clean the tube from the reverse side. We periodically use a cleaning aerosol that will help wash away any remaining carbon deposits and other debris from the pipe. You can use a liquid lubricant like WD-40, which also removes carbon deposits and other contaminants well. After this, the pipe is purged again, and if air passes through it, the throttle valve is replaced and engine oil will no longer appear in the air filter.

When assembling the air filter, you need to thoroughly clean the corrugation so that there are no oil stains left on it. If the filter itself becomes dirty, it is better to replace it, otherwise the air supply to the engine will be difficult, which will negatively affect its operation. After this, the car can be operated normally.

To check the effectiveness of the repair, after a month it is advisable to remove the air filter bellows and carefully inspect it. There should be no oil drips or splashes in its opening. If they appear, you need to clean the throttle tube again using one of the proposed methods. But recurrence of the problem after a month of operation is rare.

Replacing the pipe: how it happens

When undergoing scheduled or unscheduled maintenance, a malfunction is detected, the corrugation should be replaced. This work is not difficult or difficult.

Repair begins with unscrewing the retaining clamps or mounting bolts.
Remove the unusable pipe.
Replace with a new element and tighten the clamps or fastening nuts tightly to avoid further air suction.

To replace, you need to use the original corrugation. Follow the manufacturer's recommendations in this matter. For this purpose, there is an article listed in the catalog of original spare parts for modern cars.

What is it for? The original spare part will fit into place without any problems. Using a supplier's part or purchased corrugation on the market, get ready for installation problems.

When ordering a product from an online store, ask the manager about the quality of the corrugation. Agree with him to purchase goods from a normal manufacturer, and not a packaging company.

This service will cost 10-15 percent more than the samples put up for sale. But, in this way, you can bypass the problems with installing a low-quality element.

Having installed corrugations of dubious origin, it can be assumed that in the near future problems will arise in the operation of the power unit.

For your information. When cleaning the pipes from the air filter to the turbine and from the turbo/compressor to the intake manifold, attention should be paid to removing sand and dirt.

What to do to prevent oil from getting into the filter

The problem with oil getting into the air filter is typical for older engines that have traveled more than 150-200 thousand kilometers. To delay as much as possible the moment when engine oil begins to enter the filter element, it is recommended to properly monitor the engine:

Buy high-quality oil recommended by the car manufacturer. Remember that motor oil from major brands is often counterfeited, so you should purchase the fluid from reputable stores;
Change the oil after a maximum of 10 thousand km.
Fill the fuel tank with high-quality gasoline ;
Change the air filter every 10-15 thousand kilometers . There is a “golden rule”: the filter should be changed 5 thousand kilometers earlier than the car manufacturer recommends. For example, if the technical manual for a car states that the filter should be changed every 20 thousand kilometers, do this after the car has traveled 15 thousand kilometers.

High-quality consumables are the key to the “health” of the engine. It is better not to skimp on oil, gasoline and filters so that the need for major engine repairs does not appear too early.

There are oil in the air filter corrugation - VAZ 2112 - 16 valves, the main reasons

How to prevent oil from getting into the air filter

VAZ 2110 Air filter and sound-absorbing pipe

The air intake by the engine contains dust and dirt particles that should not enter the combustion chambers, as they act as an abrasive on the cylinder walls and cause premature wear of the pistons and cylinder working surfaces. The air filter filter element cleans the air entering the engine cylinders and is located in the air filter housing (sound-absorbing pipe). The sound-absorbing pipe performs a very important task: it calms the uncontrolled rotating flow of fresh air and at the same time suppresses the noise generated by the air intake. In the Fiesta, the sound-absorbing pipe consists of a plastic housing and a fine-pored, accordion-shaped air filter element.

Air Filter Maintenance

The sucked air passes through the air filter housing, inside of which the filter element is secured with two plastic gaskets. The entire air flow passes through the filter, while dust and all dirt particles that accelerate engine wear are retained by the filter element. Larger foreign particles, such as insects or grains of sand, remain in the air filter housing. The air filter and filter element only function properly if they are constantly checked and maintained in good condition. A dirty filter element does not clean the intake air, which leads to a deterioration of the air-fuel mixture, increased toxicity of exhaust gases, and a decrease in engine power with increased fuel consumption.

Cleaning the air filter element

The filter element and oil catcher in those engine versions where it is installed must be cleaned at least once a year and changed once every two years

You need to purchase filter elements in specialized stores, and they do not necessarily have to be only original, but in any case, pay attention to the quality

Question No. 1: why is the car air filter covered in oil and the reasons for this phenomenon?

This question arises among some car enthusiasts during the next air filter replacement; moreover, this fact causes confusion among many. According to their opinion, there can be no connection between the lubrication and air filtration systems of internal combustion engines. However, even minimal knowledge of the principles of operation of the power unit makes it possible to refute this concept.

In fact, the answer to the riddle of why the air filter is in oil is simple - in addition to the main air flow, crankcase gases also pass through the filter element. Moreover, their concentration is directly proportional to engine wear. Serious problems with the cylinder-piston group lead to the penetration of lubricating fluid into the crankcase and the appearance of excess pressure, which destroys the seals. All these factors contribute to unwanted penetration of lubricant into the air filter.

Based on the experience of practicing craftsmen, we can outline the most common reasons why oil ends up in the filter element:

High levels of wear and coking of the piston rings, which does not allow excess lubricant to be effectively removed from the cylinder walls, and the substance penetrates into the crankcase.
The oil deflector drain is clogged and the remaining lubricant cannot return to the crankcase, so the air filter is filled with oil supplied with crankcase gases.
Clogged crankcase gas throttle outlet hose.
The filter element loses its performance characteristics; in other words, the air filter becomes contaminated with dust. Due to the insufficient volume of incoming air, the engine begins to compensate for this parameter by suction from the crankcase.

Air pipe

The air pipe is connected to the air cleaner. The float chamber cover contains a needle valve 11, a float 12, a balancing tube 4, an accelerator pump nozzle 5, and a number of connecting channels.

Air pipe - air pipe 7 is used to suck air into the impeller.

From the air pipe, air is directed into the diffuser, where its speed increases significantly and the pressure decreases. To reduce losses during air flow, a diffuser is used with angles at the inlet of 30 and at the outlet of 7 and with a smooth transition of the profile. In practice, the profile of diffusers, especially for carburetors with a single diffuser, differs from the optimal one due to the need to reduce the height of the carburetor. When departing from the most favorable ratio of the dimensions of the diffuser, the jet of moving flow is compressed, which, in turn, leads to a displacement of the zone of greatest rarefaction along the air movement. The movement of the air flow in the carburetor diffuser in a wide range of modes is turbulent. Turbulent air movement with intense turbulence is necessary for better crushing of the fuel flowing from the atomizer at significant speed.

The design of the air pipe prevents the siphon release of the sludge evaporator contents into the sewer.

The float chamber, air pipe with air damper and acceleration pump are common to both mixing chambers.

When the engine is not running, the carburetor air pipe is closed with a cover 35 sealed with a felt gasket.

The dimensions of the flow sections of liquid and air pipes are calculated based on the condition of continuity of flows. In this case, the permissible speed of liquid flow through the pipe is assumed to be no more than 16 m/sec, air flow – no more than 75 m/sec.

An air pipe with an air damper and a separate float chamber cover are installed on top of the body.

From the atmosphere, air passes through the air purifier and the air pipe through the minimum cross-section of the diffuser, where its speed increases significantly and the pressure decreases.

Why do you need a cold intake and how to implement it

We noticed that in hot weather, in a traffic jam or at traffic lights, the car accelerates worse, and after a while the throttle response returns. This is due to the fact that if the engine temperature is higher than the opening temperature of the thermostat, but lower than the temperature when the fan is turned on, then the system to prevent detonation delays the ignition to the late side. After you start driving, the air flow cools the radiator to the opening temperature of the thermostat, and the dynamics return. The system, realizing that the temperature has dropped, returns the OZ to its previous value.

There are several ways to make a cold air intake for the engine:

Using aluminum corrugation
Using plastic pipes

Cold intake made of aluminum corrugation

As a result, the new highway will have a snail shape. This design has been tested for years, and we can say that it is not inferior in reliability to the standard one.

Where to do the work

You can do the work yourself. This can be done in the garage or at +t0 outside. Just watch the video and purchase the original corrugation recommended for use by the manufacturer.

If other complex measures are being carried out, it is better to entrust the replacement to the service station masters. They perform work in accordance with established standards using modern equipment. And they will install the original corrugation. At least they have all the conditions for this. And also, the service station technicians provide a guarantee for the installation.
