Removing the exhaust manifold VAZ Kalina 8 valves

Replacing the exhaust manifold and gasket

When dismantling the manifold, the gasket is destroyed in almost any case. Therefore, it is worth removing its remains from the parts. Replacing the Kalina exhaust manifold gasket is a simple process. The use of sealants and other third-party substances is not recommended. They may later get into the crankcase.

Replacing the manifold itself is simple - just take a new part and install it according to the principle in which it was attached. Assembling the system is simply the reverse order of the steps outlined in the last section.

Advice! Don't forget about cleanliness. This is an important factor in long and trouble-free operation of the car.

Manifold dismantling procedure - step-by-step instructions

The dismantling process itself is not so complicated; access to some nuts is difficult, so it is advisable to carry out the work on a lift or in an inspection pit. The algorithm of actions for the injection VAZ-2114 in this case looks like this:

Remove the negative terminal from the battery or turn off the mains switch.

Drain the coolant from the system

Removing the fuel pipes

Disabling the throttle position sensor

Disconnect the muffler exhaust pipe from the manifold

Dismantling the exhaust manifold mountings

Replacement of gaskets and installation of manifold

After dismantling the manifold, it is rarely possible to remove the gasket intact. It changes in any case, but parts of the destroyed gasket will definitely remain on the mating plane on the head side and on the manifold side. They must be carefully removed.

Changing the manifold gasket

To do this, you can use a special spray that softens the gasket residues; you can carefully remove them with a blade. In this case, the plane must not be damaged, otherwise the tightness of the connection will be broken.

Also, when installing new exhaust manifold gaskets, it is not recommended to use sealants. They can be of different quality, and during crimping they can form particles that get into the crankcase, which is extremely undesirable.

The main reasons for replacing the catalyst gasket

One of the main reasons for catalytic converter failure is that the exhaust channels become clogged. The formation of plugs leads to the deposition of soot, soot, and other solid deposits. Sources of clogging can be:

• low quality fuel;
• the use by the owner of the technical equipment of all kinds of chemical additives in the combustible mixture (these reagents only have a detrimental effect on the performance of the fuel system);
• possible mechanical damage to the housing or internal connections;
• long-term operation without replacement or prevention;
• faulty engine ignition system;
• unstable operation of the oxygen sensor, due to which the combustible mixture is lean or enriched, which also has an extremely detrimental effect on the performance of the entire system.

Gasket for Kalina manifold 8 valves

These are: fuel system, exhaust gas recirculation system. After a run of 80-100 thousand km, the metal housing of the exhaust manifold begins to crack at the seams.

Flange connections are torn away from their seats.

Replacing a catalyst with a spider, as a process, is divided into several stages.

This does not take into account the fact that the catalyst itself needs to be changed due to burnout of internal parts due to systematic contact with a hot flame flow. The average gas temperature reaches 600℃.

So, division into stages: collecting data on the number and location of catalysts in the car; preparation of spare parts in each specific case for modification;

When should the Kalina catalyst gasket be replaced?

Most vehicle owners mistakenly think that the catalytic converter, even if in good condition, is the reason for the reduction in power of the power unit.
In view of this, owners of budget car models deliberately exclude this part from the exhaust tract. However, the power of the power unit is reduced solely due to a violation of the throughput of the exhaust gas converter, due to damage to the honeycombs inside it.

Our car service specialists identify the main reasons for premature failure of parts and wear of gaskets:

• Low fuel quality;
• Use of various additives;
• Mechanical damage to elements;
• Incorrect operation of the ignition system;
• Failure of the lambda probe, as a result of which the process of formation of the fuel mixture is disrupted.

If the catalyst fails, the following symptoms are observed:

1. If the throughput of the neutralizer is completely impaired, the vehicle's power unit will start and immediately stall, or not start at all. You can diagnose catalytic converters as quickly as possible in our service center. But you can also perform an independent check, however, it is not always highly accurate. To carry it out, unscrew the lambda located in front of the catalyst, and then start the engine. If it starts, the catalyst is faulty.
2. The acceleration dynamics of the car are noticeably reduced, the speed of the power unit drops.
3. Fuel consumption increases significantly. However, this evidence of a catalyst malfunction only applies in the event of a noticeable decrease in the power and acceleration dynamics of the vehicle. To put it simply, if the vehicle begins to become “stupid” and fuel consumption increases, therefore, the converter needs to be replaced.
4. The “CHECK ENGINE” indicator on the dashboard came on. But this is not always direct evidence of a catalyst failure. In this case, you need to contact a car service for detailed diagnostics.

Restoring the tightness of the intake system on the editorial Kalina

There is nothing criminal about this.

Over time, the tightness of its joints is broken and liquid can seep out. In addition to the aesthetic aspect, this is also reflected in the operation of the motor. Through the cracks not only oil presses, but also air leaks.

Most often, this leads to uneven engine operation (slight tripping) at idle speed. Intake manifold

The tightness of the intake system is very important for the proper operation of the engine. The tightness of the intake system is very important for the proper operation of the engine. Oil traces at the manifold joints are visible to the naked eye, and air leaks can be calculated using a simple technique.

While the engine is running, spray any suspicious areas with brake system or carburetor cleaner.

If after some time the engine speed “floats” or it begins to choke altogether, then there is a significant suction in these places.

The purifier, as a flammable substance, entering the intake, enriches the air-fuel mixture, which causes the engine speed to fluctuate. The intake of additional air, not taken into account by the sensors on the intake side, causes a constant leaning of the mixture. The control system tries to adjust the fuel supply based on the output readings of the front lambda probe.

Reasons for removing and replacing the exhaust manifold Lada Kalina

The exhaust manifold is made of cast iron, which is very resistant to temperatures. However, a critical temperature - 800-900 degrees - can render the distributor unusable. In addition, there are many other factors that negatively affect it. This list can include:

• Mechanical damage;
• Loss of tightness at the junction with the cylinder head (cylinder block);
• Inoperative condition of the gasket between the BC head and the manifold;
• Due to constant overheating, cracks or warping may occur.

Sometimes replacing the exhaust manifold on Kalina 8 valves is necessary in order to install a more advanced and high-quality part.

Important! The exhaust manifold gasket is created from pressed reinforced asbestos and is necessary to create a tight connection between the BC head and the distributor. The fact is that the BC head is made of aluminum, and the manifold is made of cast iron. Therefore, under the influence of temperature, these two elements expand and contract differently. And asbestos allows you to coordinate the difference in thermal expansion. The main threat to the gasket is constant exposure to high temperatures.

There are a number of symptoms that will tell you that you need to replace the exhaust manifold of your Lada Kalina:

• In any operating mode, the engine makes an unpleasant characteristic sound;
• Exhaust gases enter under the hood or even into the interior of your car;
• The engine loses power due to a mismatch between the BC head and the manifold.

When is it necessary to replace and remove the exhaust manifold on a VAZ-2114

Huge temperature changes are the main problem faced by the exhaust manifold and the gasket, for which it is removed. The collector itself is made of a special grade of cast iron; it can withstand high temperatures (up to 800-900 degrees), however, these are critical values, after which the collector may warp or crack.

Exhaust manifold VAZ-2114

Its main task is to collect exhaust gases and distribute them into the exhaust pipe of the muffler.

Replacing or dismantling the VAZ-2114 exhaust manifold is necessary in the following cases:

1. Mechanical damage to the collector.
2. Warping and loss of tightness at the junction with the cylinder head.
3. Burnout of the gasket between the head and the manifold.
4. The appearance of cracks as a result of engine overheating.
5. Replacing the collector with a device of a different configuration, adapted to a more severe operating mode.

In the event that we are not going to participate in high-speed races for the prize of the head of the regional traffic police, replacing or dismantling the collector may be necessary in a number of cases.

Replacement of the intake pipe gasket and catalytic collector

The intake pipe and catalytic collector are connected to the cylinder head through a common sealing gasket. The gasket also covers two channels of the cylinder head cooling jacket, which extend into the plane of the junction of the head with the intake pipe and catalytic collector. We carry out the work on an inspection ditch or overpass. Drain the coolant from the engine (see “Checking the level and replacing the coolant”). We remove the receiver (see “Removing the receiver”) and the fuel rail with injectors (see “Checking the injectors, removing the fuel rail and injectors”). Disconnect the engine management system wiring harness block from the oxygen concentration sensor wiring harness block (see “Removing the control oxygen concentration sensor”). Having unscrewed the three nuts securing the pipe flange of the additional muffler to the flange of the catalytic collector, we disconnect the additional muffler from the catalytic collector (see “Removing the additional muffler”).

Replacing the manifold gasket

The exhaust manifold is a device through which gases formed during fuel combustion enter the exhaust pipe. Regardless of whether the engine is running on diesel or gasoline, gases are produced and they must escape somewhere.

On one side, the device is tightly connected to the cylinder head, and on the other, it is connected to the exhaust pipe or converter.

In addition to removing exhaust gases from the engine cylinders, the unit ensures uninterrupted operation of the engine and the entire car. This happens due to the purging and filling of the combustion chambers.

Lada Kalina (8, 16 valves): replacing the catalyst with a spider or flame arrester

LADA Kalina has been produced since 2003, when the first copies rolled off the assembly line.
Before this, prototypes of future production models were repeatedly tested. The process of creating the model itself turned out to be quite difficult and lengthy.

The first developments began back in 1999 and lasted until 2003.

During its existence, the model has undergone repeated updates. There were four in total:

• 1.4 liter engine, 16 valve mechanism, Euro standardization – 3, 4;
• 1.6-liter engine, 16-valve mechanism, Euro standardization – 3, 4 (production started in December 2009);
• 1.6-liter engine, 8-valve mechanism, Euro standardization – 2, 3 (subject to the “Basic” package);
• 1.6-liter engine, 8-valve mechanism, Euro 4 standardization (Lux+ package from November 2011).

Despite the many positive aspects of the car and the brand as a whole, it is necessary to highlight a number of weak points. These are: fuel system, exhaust gas recirculation system.

After a run of 80-100 thousand km, the metal housing of the exhaust manifold begins to crack at the seams. Flange connections are torn away from their seats. This does not take into account the fact that the catalyst itself needs to be changed due to burnout of internal parts due to systematic contact with a hot flame flow. The average gas temperature reaches 600℃.

Technical features of the insert for Lada Kalina 8V

The industry offers two types of tuning inserts, the design of each of them depends on the location of the pipes. Moreover, each design is designed for a specific power unit:

1. Insert 4-1 is installed on forced engines with a speed range from 5,000 to 10,000 rpm. structurally suitable only for 16-valve engines.
2. The 4-2-1 insert operates over a wider range and is considered a "low-end" insert. It is possible to increase engine power by about 3-5%. This is the model most often installed on the VAZ 1118.

Since it will not be possible to install a preliminary flame arrester on this VAZ car, you will have to carefully approach the issue of choosing an insert. The installation process of the part will not take much time if you follow all the recommendations.

How to install a 4-2-1 spider in place of the standard converter on a Lada Kalina 8V

In a car exhaust system, a catalytic converter is needed to burn harmful elements in the exhaust gases to the level of H2O and CO2. It is quite difficult to predict its service life, since it depends on many factors. But many owners of VAZ cars prefer to get rid of the collector before the end of its service life. For these purposes, they use special inserts, which are an inexpensive alternative to a neutralizer.

Contents Some car enthusiasts are sure that even a working neutralizer prevents the engine from developing the power it needs. This is not true. As for clogged or melted honeycombs, this phenomenon is the result of careless handling of the vehicle and its operation with a faulty fuel supply and ignition system.

The main reasons for device failure:

1. Unbalanced fuel-air mixture due to a broken oxygen sensor.
2. Unsatisfactory fuel quality.
3. Incorrect ignition operation.
4. Mechanical damage to the collector.
5. Use of fuel additives.

For the most part, replacing the catalyst on Kalina 8 valves is done as a result of using low quality fuel. Its slow combustion occurs partly in the exhaust. The detonation of gasoline destroys the ceramic structure of the honeycomb, which over time begins to crumble and clog thin passages.

The engine begins to overheat and loses traction. An obstacle to the free passage of gases contributes to an increase in their pressure.

Technical features of the insert

Installing catalyst replacements can eliminate the problem of a clogged exhaust filter and return the car to its previous performance - power and gas mileage. But what are these substitutes? This insert is a hollow pipe that does not have filters. It is made in the form of a catalyst and in most cases there are no problems with its installation. After installing the insert instead of the factory exhaust gas filter, drivers observe:

• acceleration of warming up of the car in the cold season;
• the car picks up speed better;
• fuel consumption is reduced.

In some cases, there is a change in the sound volume when the car is running. The sound becomes more bassy. The Lada Kalina computer can display “Check” on the dashboard when driving with the insert. To prevent this, use a lambda probe or oxygen sensor. This sensor is an integral part of the exhaust system with a catalyst. The sensor analyzes the level of oxygen and harmful gases in the exhaust and transmits the information to the on-board computer. Based on the data obtained, the computer determines the performance of the catalyst. The lambda probe cannot be repaired; if it breaks, the part must be replaced.

Since the insert does not reduce the level of toxic substances in the exhaust, the lambda probe will constantly transmit information about a catalyst malfunction. To avoid this, special devices are used - decoys. They come in two types: mechanical and electronic.

Lambda zone deception

Mechanical blende is a bronze spacer of a certain size, filled with ceramic chips coated with a catalytic layer. Exhaust gases pass through the small holes of the device, interacting with the crumbs, due to which the CO2 concentration is reduced. Electronics analyzes the changes and sends information to the computer about the normal operation of the catalyst.

Electronic snag is a high-tech device based on a single processor. Such a device analyzes the operation of the exhaust gas purification system and transmits information about the serviceability of the catalyst. The electronics understand that smog filtering is not happening, but generates a signal corresponding to the correct functioning of the system.

You can replace the catalyst with an insert in many car repair shops. Self-replacement is recommended only if you have the appropriate tools, skills and experience. You can install electronic deception yourself, but you need to have a good understanding of the principles of computer operation and have the necessary software. Otherwise, the car owner risks making the situation worse.

Replacement of intake manifold gaskets VAZ 2114 8 cl (Kalina, 2110)

21.03.2019 2095

It is recommended to replace the gaskets on the VAZ intake manifold after each removal. But I had to do this prematurely, as I discovered a significant air leak, which mainly manifested itself on a cold engine. Every cold start was accompanied by a terrible tripping.

In addition to the tripping when cold, there was a slight drop in speed when sharply pressing the gas pedal. This applies to both a cold and a hot engine.

A homemade smoke generator made from a cigarette helped me detect the air leak. A very simple and primitive contraption that has helped me out more than once.

My car (Kalina 1.6 8 valves) has a plastic intake manifold (receiver). The same will be installed on all VAZ family cars with an 8-valve 1.6-liter engine (2114, 2110, etc.). 4 rubber rings act as gaskets. According to reviews, black rings last much longer than white ones. And I was convinced of this personally - these gaskets lasted for about six months and began to let air through. They felt like plastic to the touch. Unfortunately, I didn’t find black ones, so I’ll install white ones again. I hope these last longer.

To remove the intake manifold (receiver), you must first unscrew the corrugation from the air filter, the throttle cable, and the small crankcase ventilation hoses. I will not remove the throttle and its heating.

The intake manifold is attached to 5 studs - one in the center, two on the sides. To unscrew them you will need a 13mm socket. After unscrewing the nuts, you need to remove the receiver itself from the studs and move it to the side. Remove the old gaskets and wipe the seats from oil and dirt. You also need to wipe the seat on the engine.

The manifold has special grooves for guides on the gaskets. The gaskets must be installed with the higher side in the plastic manifold. It is the guide that will prevent you from making mistakes.

I additionally coated the areas near the guides with sealant on the outside of the gasket. Because it felt like that was where the ring entered the groove the deepest. In addition, there was a place for air leaks on the old gaskets.

After all procedures, the intake manifold can be installed back. I couldn't find any information on how tightly to tighten the mounting nuts. I delayed it at my own peril and risk. The main thing is not to overtighten, as the manifold is plastic and can crack.

This is how I replaced the old intake manifold gaskets on my Kalina with new ones. There is no more air leakage, the engine stopped stalling when cold and began to behave much better when warm.

What kind of manifold gasket is installed on Kalina

But their fixation areas are the same. They are removed according to the same scheme, illustrated using the example of a VAZ-21126 engine. Info The difference is the presence of wires and pipelines.

1. Remove the negative terminal wire from the battery.

2. Important Unscrew the ignition coils.

3. Remove the throttle assembly from the inlet pipe.

4. Loosen the tie that holds the exhaust breather of the crankcase ventilation structure to the cylinder head cover pipe, 5. disconnect the breather from the pipe. 6.

But if you follow the instructions, everything will work out.

Well, if you can’t do it, then go directly to a car service center.

Particular attention should be paid to the quality of the product so that you do not have to change the part after several thousand kilometers.

carfrance.ru The Lada Kalina, equipped with an injection engine, cannot be called expensive or difficult to maintain. If problems arise, for example, with the exhaust manifold, then everything can be solved on your own. The exhaust pipe is necessary to collect and redirect exhaust gases to a special exhaust pipe of the muffler.

You can replace the Kalina exhaust manifold at home. The exhaust manifold is made of cast iron, which is very resistant to temperatures.

Remove the old gaskets and wipe the seats from oil and dirt.

You also need to wipe the seat on the engine. The manifold has special grooves for guides on the gaskets. The gaskets must be installed with the higher side in the plastic manifold.

It is the guide that will prevent you from making mistakes. I additionally coated the areas near the guides with sealant on the outside of the gasket.
