Faults and engine repair 2114/2111
The VAZ 2111 engine, or as the people call the 2114 engine, is essentially the same eighty-third, the main differences between the 2114 engine and the use of an injector instead of a carburetor, a floating connecting rod finger and a slightly different camshaft, it is also 6 Horse power more powerful. Accordingly, all modern Lada engines were developed on the basis of this motor, such as 124, 126 (Priora motor), 127, 114, 116, 119 (Kalina motors). Was replaced by 1.6 liters. 8V motor VAZ 21114.
VAZ 2114 engine 1.5 liters. injection in-line 4-cylinder with an overhead camshaft, the timing belt has a belt drive. Engine number 2114 is stamped on the block under the thermostat. The resource of the VAZ 2114 engine, according to the manufacturer's data, is 150 thousand km; in practice, the motors run more than 200 thousand km, with normal maintenance. For example, the oil change in the 2114 engine should be carried out on a warm engine, at least once 10-15 thousand km. When signs of malfunction appear, the lamp "check the engine VAZ 2114" is on, you need not to start and immediately go to diagnostics or look for the cause yourself.
A feature of the 2114 motor does not bend when the timing belt breaks.
The motor is not without its drawbacks, valve adjustment is still required, the cooling system parts are worn out, the oil filter must be constantly changed, oil flow through the seal valve cover, fuel pump and the sensor-distributor, breaking off the fastenings of the receiving exhaust pipe due to the use of steel nuts instead of brass ones, injection system failures are possible on older cars. The operating temperature of the 2114 engine is 95-103 degrees.
Now in more detail about the most common problems, the first of them: engine speed 2114 is floating, what is the reason? Usually this happens at idle and on new cars, if this is your case, go to diagnostics and do under warranty, if not, then look for the problem in idle speed regulator, position sensor throttle or in a vacuum cleaner.
The same reasons (+ a problem with the mass air flow sensor) are relevant if the 2114 engine stalls on the move.
Moving on, does your 2114 engine troit, undermine or run unevenly? We measure the compression, if the compression in one cylinder is much lower - the valve is burned out, if the run is small - we adjust the valve or the problem is in the gasket. If the compression is ok, then the reason is in the ignition module.
We figured it out, the next popular malfunction is that the VAZ 2114 engine does not heat up to the prescribed working temperature... The reason is simple - the thermostat, if you recently changed it ... change it again, it has arrived. Quality!
Knocking and noise in the VAZ 2114 engine is also not uncommon. The most common cause is unregulated valves. A dull metallic sound increasing when you press the gas pedal - the main bearings of the crankshaft or connecting rod bearings are knocking, you need a service. Pistons in the cylinder can also knock, you cannot do without service.
VAZ 2114/2111 engine tuning
Chip tuning of the VAZ 2114 engine
For atmospheric engine Chipping is useless, the improvement will be so small that it is impossible to feel it.
Increase engine power VAZ 2114
Consider the potential of a 2111 8V motor without replacing the cylinder head with a 16 valve. The 103 16V engine and its modifications are mentioned in a separate article.
The easiest way to improve something is to replace the camshaft with OKB Dinamika 108 or Nuzhdin 10.93, install a split gear, adjust the phases. At the output we will get around 85 hp. at a minimum cost and a slightly more active motor. Let's let the motor breathe freely, put the receiver, the throttle valve 54 mm and the exhaust spider 4-2-1 we get already under 90-95 hp and the dynamics at the Priora level. To this we add the revision of the cylinder head and the intake manifold, light valves, cylinder head milling, the power will jump to 100 or more hp.
For a further increase in power, it is recommended to increase the volume of the 2111 engine to 1.6 liters, by increasing the stroke to 74.8 mm.
When using valves with an increased diameter, lightweight valve discs, setting the program, the car will show 110 or more hp, but in this configuration it is necessary to select evil shafts with a wide phase and a large lift. We will get an excellent sports engine for a VAZ 2114 with a power of 120-130 hp. and more.
Compressor for VAZ 2114
An alternative method of obtaining such power is to install a compressor with a pressure of 0.5 bar. With the correct setting and using the Nuzhdin 10.42 shaft or the wider Nuzhdin 10.63 (or other manufacturers with similar characteristics), the motor will give out about 120 HP + \ -. The well-known video explains everything that is required for the successful implementation of the project.
Attention MAT (18+)
It is possible to increase power without using a turbine up to 170 hp. and higher, but the resource of the VAZ 2111 engine is sharply reduced.
It is possible to significantly increase the potential by installing a 16-valve cylinder head, with a receiver, a 54 mm damper and 51 mm on the exhaust, a return of 105-110 hp. occurs without loss of resource.
Rotary engine for VAZ 2114
A good way to sharply increase the power by 2 times. About the rotor at the very bottom is written ano.
On cars of the Samara 2 series, the Volzhsky Automobile Plant installed injection engines with electronic, distributed fuel injection. And for the VAZ 2114, which appeared in 2001, and was launched into the series in 2003, the following was developed power point- model 2111. In subsequent years were produced various modifications this car and some of them were equipped with other engine models, such as - 21114, 11183, 21124 and 21126. But the most massive production cars were VAZ 2114 with engines of models 2111 and 11183.
The design of the VAZ 2114 engine
The main hallmark of all engine models on the VAZ 2114 is that an injector is installed on them. Electronic control fuel injection, depending on the readings of a large number of different sensors that monitor a variety of parameters, up to the composition exhaust gases certainly contributes to balanced and economical engine operation. The engine itself on the VAZ 2114 is an in-line, four-stroke, eight-valve unit with a camshaft on top. It has four cylinders, runs on gasoline and is cooled special liquid... In the engine compartment of the car, the engine is located transversely to the direction of travel. The photo of the VAZ 2114 engine shows its real location relative to other units. Cylinder block of this power unit made of cast iron by casting. All holes for antifreeze are formed in a casting mold, oil passages are machined mechanically... The working cylinders are also machined. At the bottom of the block there are main bearing supports, the covers for them are made during the manufacture of the block, they have an individual fit, so it is impossible to replace them. When disassembling, you need to pay attention to the marking of these covers so as not to confuse them. Liners made of steel and aluminum alloy are inserted into the covers and supports. In the third support, thrust half rings are inserted that prevent axial movement crankshaft.
Specifications VAZ 2114

During the operation of the internal combustion engine on a car, various failures and malfunctions may occur, which are eliminated when self-repair or with the involvement of specialists. The need for overhaul of the power propulsion system, when it correct operation, occurs when reaching 150,000 km of run. In this case, a VAZ 2114 engine bulkhead is needed.
When rebuilding the internal combustion engine, it is required to carefully inspect each unit, assembly or part. Upon detection mechanical damage the spare part is subject to mandatory replacement. All gaskets, washers and non-metallic parts are also required to be replaced.
Overhaul of the power unit will require more in-depth knowledge of the design and principle of engine operation, but if desired, every motorist is able to figure it out and carry out these operations with his own hands.
It is worth noting that when diagnosing faults, it is worth carefully and carefully examining every detail for defects. 8-valve device injection engine VAZ-2114 is quite similar to the first generations of this engine - "Samara". Of course, the designers made many changes to the features of the power unit, but in many ways they remained similar. Repair and service this engine it is necessary to carry out regularly, which will extend not only its resource, but also reduce the wear of the parts that are located inside.
Sensors VAZ 2114
A modern car with an injection engine is a complex mechanism that is a combination of numerous units and electronic devices... They are controlled using various sensors. In order to use them correctly, you need to know where and what sensors are on the VAZ 2114. Sensors are installed in order to signal the state of systems, the level of liquids, emergency situations... They are located on the engine, transmission, body and electronic circuits... Almost all VAZ 2114 sensors are installed on serial cars as standard. However, some can be supplied by the car owner on their own or during the tuning of the car, as an additional option. List of major measuring instruments placed on serial VAZ 2114, this is a sensor:➤ oil pressure; ➤ temperature of antifreeze; ➤ antifreeze level; ➤ fuel level; ➤ idle; ➤ mass air flow; ➤ fluid level in the brake system; ➤ throttle valve position; ➤ speed; ➤ crankshaft position; ➤ the position of the camshaft, it is also the phase sensor; ➤ oxygen; ➤ detonation; ➤ uneven road; ➤ ambient temperature. The list is quite solid, but car owners do not calm down and improve their cars by installing additional devices... The following options are most often installed as options: open doors; ➤ front wear gauge brake pads; ➤ light sensor device. Coolant temperature gauge. It is also called the engine temperature sensor. On the forums, the question is often asked - where is the engine temperature sensor VAZ 2114. It is installed on the inlet pipe of the cooling jacket of the cylinder head. It is quite simple to check its performance. It is enough to connect an ohmmeter to it and lower the DTOZH into a vessel with liquid. When heating it, it is necessary to monitor the temperature and the change in resistance due to its increase. If the required schedule is met, the device is considered to be in good working order. Coolant level sensor - stands in a tank with antifreeze. It is screwed on like an ordinary plastic cover, then the electrical connector is connected. Level sensor brake fluid- float-type device, installed in a reservoir with brake fluid. The idle speed sensor, or IAC, is installed on the throttle assembly next to the throttle valve. Mass air flow sensor - located on the body air filter near the large inlet. Throttle Position Sensor - Located on the throttle body. Crankshaft position sensor. It is also called a synchronization sensor, due to the fact that the controller, according to its readings, synchronizes its work with the injection system. Installed next to the alternator drive pulley. Camshaft position sensor or phase sensor - located on the side of the air filter next to the cylinder head cover. Depending on the position of the camshaft, it gives an impulse to the computer and is injected just before the valve opens. The fuel is thrown in simultaneously with a portion of air, mixes well and a high-quality detonation occurs. Oxygen sensor or lambda probe. Stands in the intake manifold exhaust system in front of the resonator. Gives a signal to the electronic on-board system on the level of oxygen concentration in the exhaust gases. Knock sensor - installed between the second and third cylinders on the power plant block from the fan side. Its readings, through the controller, affect the ignition timing. These are all the main sensors on the VAZ 2114 engine. However, there are other sensors that give readings from the VAZ 2114 indicating its performance or condition the environment or road surface. Fuel level meter - located in the intake chamber fuel tank... A sensor of the DUT-1-03 type is installed on the VAZ 2114. Speed meter - stands at the checkpoint and transmits data about the current speed of the car to the speedometer. It is also connected with the controller, which, receiving its impulses, regulates IAC work or the throttle valve, on what position the gas pedal is and what the engine speed is. Rough road retainer (sensor) - it is mounted under the hood on the body in the area of the right mudguard cup. It reports changes in body vibration to the controller, if the signal level is exceeded, the electronics disables misfire diagnostics. The overboard temperature sensor (that is, the ambient atmosphere) is its standard location on the VAZ 2114 - in the center behind the front bumper. During the operation of the car, the driver constantly monitors the state of systems and assemblies using instruments, warning lights and on-board computer... The readings on them come from the measuring instruments that are installed throughout the car; sometimes the life of the people in the car depends on their correct and accurate operation. Therefore, it is necessary to constantly monitor their condition and performance, paying attention to this during the next MOT. Signaling devices called sensors are installed in order to inform the driver or some control device about changes occurring during the operation of the car or the state of the corresponding unit or system, as well as signal in case of failures or emergency conditions in the car. Therefore, the driver must have a good understanding of the principle of operation and the location of the sensors on the VAZ 2114. Oil pressure gauge... An important device that signals a low oil pressure in the engine. When this happens, it indicates a problem in the propulsion system. The most serious consequence of ignoring this signal can be overhaul or complete replacement engine. Bulb emergency pressure oil associated with the sensor lights up in several cases: the oil level has dropped significantly; clogged oil filter; the oil pump has failed; the oil pressure sensor is faulty; faulty wiring or oil pressure drop due to leaks. On an eight-valve engine, the sensor is located on the right side below the valve cover in the head of the blocks. On the sixteen-valve - on the left end of the camshaft bearing housing. The design of the DDM is extremely simple, and its price is low, therefore, if it is out of order, it is more economically profitable to buy a new one than to repair it.The VAZ 2114 car is a high-quality modification of the most successful creation of Volzhsky automobile plant VAZ 2109. The model was named "Samara 2". Its presentation took place in 2001. Whereas the car entered mass production only in 2003. Later, an even more improved VAZ 2114 16 valve appeared on the domestic market. It is this model that we will consider in more detail in our review.
Differences between VAZ 2114 and VAZ 2109
The improvements of the VAZ 2114 in comparison with the prototype turned out to be more than serious. They touched and appearance, and the technical part of the car.
The designers of 2114 have made a number of changes:
- installed new front and rear bumper;
- updated version of the hood cover;
- the model has received improved optics;
- the radiator lining was carried out;
- added a package of moldings.
The interior of the car has changed even more. Here the dashboard was completely replaced and wheel... To improve the comfort of passengers and the driver, engineers have replaced the outdated heater. Also 2114 received new design front wipers.
VAZ 2114 engine
The most expected changes in the VAZ 2109 concerned the power plant. In the first generation, the model used an 8-valve 2114 engine. It had a displacement of 1.5 liters. In the next update of the VAZ 2114, which took place in 2007, this engine was replaced with an improved one with a volume of 1.6 liters.
Installation 16- valve engine on the VAZ 2114 became a real breakthrough for the model. This modernization was carried out entirely under the supervision of ZAO Super-Auto, which is part of OAO AvtoVaz. The most important characteristic 16 valve VAZ 2114 - maximum power 89 hp Thus, the car on the technical side came close to budget cars foreign production.
For comparison, we suggest that you consider the following table of dynamic indicators:
Road characteristics of the VAZ 2114
In addition to the fact that a 16 valve engine was installed on the model, the VAZ 2114 was significantly re-equipped to improve road properties. Machine gearbox with gear ratio 3.7 received new package"closed" bearings, which significantly increase the reliability and performance of the system, in particular the torque of the car.
For brake system 16-valve VAZ 2114 engineers used larger diameter (up to 200) than in 2109, brake discs clutch. In addition, the brake cooling system has been improved, which made it possible to achieve not only safety, but again reliability.
The designers managed to achieve great success in terms of the stability of the car. This was mainly made possible by the installation of shock absorbers with increased energy intensity, as well as struts from the 2107 model. This set of procedures led to an increase in body rigidity, road stability, maneuverability and durability.
Price for VAZ 2114
Of course, most car owners domestic production choose VAZ cars precisely because of the low cost. Price for 16 valve vaz 2114 is in an equally acceptable range, but at the same time you can count not only on economy, but also on a fairly good performance of this vehicle.
Prices today for a 16-valve model fluctuate around 300 thousand rubles.
On cars of the Samara 2 series, the Volzhsky Automobile Plant installed injection engines with electronic, distributed fuel injection. And for the VAZ 2114, which appeared in 2001, and was launched into the series in 2003, such a power plant was developed - model 2111. In subsequent years, various modifications of this machine were produced and on some of them other engine models were installed, such as - 21114, 11183, 21124 and 21126. But the most massive production cars were VAZ 2114 with engines of models 2111 and 11183.
Engine tuning theory
The concepts of "engine tuning" and "budget tuning" are incompatible, so here I have almost nothing to say. Of course, the most effective measure in tuning a motor is an increase in displacement. Only this gives a simultaneous increase in power, torque in the entire speed range - from the modified VAZ-2112 engine with a volume of 1.8 liters, you can get a torque of more than 20 kg / m, and the maximum thrust of 10 kg / m of the standard motor 2110 can be curbed already from 1500 rpm min! Another measure is installation of various kinds compressors, replacement of fuel with more "fuel" (nitromethanol, ie alcohol), supply of an additional fuel oxidizer (nitros), but it is expensive. And even the little that can be done with a smart investment requires the hands of a master and a lot of experience. Therefore, I will dump here not only the engine itself, but also the power supply, ignition and exhaust system. Timing- the gas distribution mechanism is the only place available to budget tuning where you can get a "boost". Theory. The camshaft determines the valve lift (and the more it is, the better - over the entire engine speed range), as well as the timing and duration of valve opening. Unfortunately, we cannot lift the valve as much as we want: the valve springs will choose the gaps between the turns and break. To raise the valve even higher, the cylinder head needs to be revised - first, lower the valve seats (for example, for MM54 - by 1 mm), then more radical measures - replacing springs, pushers, etc. - not budget. Therefore, for the 2108-2111 motor, the maximum allowable valve lift is 9.7 mm, i.e. without alterations to the timing, you can put a camshaft "", "Nuzhdin" or their equivalent.A few words about the time and duration of valve opening - phase width. The higher the engine speed, the earlier to top dead center (TDC) the intake valve must be opened and later closed. This is necessary in order to provide a mixture with a large inertia for high revs, the ability to fill the cylinder as completely as possible and release the burnt charge. Accordingly, at the release phase, it is also necessary to act ahead of time, so that by the time the nmt is reached, when the hot mixture no longer does work, let it start to leave the cylinder, and also delay Exhaust valve open after TDC in order to remove as much exhaust gas from the cylinder as possible. At low revs, this leads to the fact that not yet fully escaped exhaust gases enter the intake system, not letting in the fresh mixture, which reduces traction at the bottom, makes it very unstable idling(therefore, on shafts with wide phases, it is necessary to increase the idle speed). On high revs overlapping the intake and exhaust phases allows for a more continuous gas flow through the CPG and, accordingly, burns more mixture and significantly increases the engine output. The relationship is non-linear: a gradual increase in phase overlap first gives an increase in torque at high rpm, gradually shifting the maximum to higher rpm. After a certain moment, the subsequent increase in phase overlap has the opposite effect - a drop in power and torque even at high speeds. When it comes to a twin-shaft motor. then the task of the master is to find such a position of the shafts at which we get the maximum torque at the maximum possible turnovers, and thus getting maximum power... In the case of a single-shaft motor, there is no need to think about this - the phase overlap is set by the manufacturer, you only need to accurately set the position of the camshaft relative to the crankshaft, and the overlap can only be changed by changing the shaft. To obtain "tractor" traction, you need a shaft with a minimum phase overlap and maximum valve lift. We will get more thrust on low revs, which is very important for a city with eternal traffic jams.
Specifications 1.6 liter engine not much different from previous versions... In comparison with the 1.5 liter, this engine became more powerful by only 4 hp. Apparently, the designers of AvtoVAZ, in pursuit of an increase in the engine resource, completely forgot about the fact that they also needed to add power. Therefore, happy car owners themselves are trying in every possible way to "add horses" under the hood. There are cases when craftsmen managed to squeeze out up to 140 hp. from the VAZ 2114 engine, the engine tuning added power almost twice as much as the factory ones show specifications... But with an increase in power, the engine resource decreases. Therefore, we will talk about how you can increase the power and at the same time shorten the life of the VAZ 2114 engine as little as possible.
It's no secret that in its standard, that is, in serial form, the engine does not develop all the power it is capable of. It is possible to configure the firmware in a new way, but the load curve cannot be drastically changed without reducing the environmental class. You can buy a "racing camshaft" to replace the stock one. But then, for new phases, it will be necessary to change the firmware ... Let's see what happens if we apply only the methods available tuning... Let's say right away, on the VAZ-2114 hatchback, the increase in power can be 20% or even 25%, and we are talking only about 8 valves. There is no need to bore the valve channels. During the tuning, the 21114 engine (1.6 liters) was refined. List of works: Bore saddle bore, which is equivalent to valve enlargement;
The throats of the canals also had to be bored a little. Thin duralumin plates were installed, which made it possible to dissolve the springs by 1.5 mm; Standard valves were replaced with lightweight ones; The guide sleeves were machined from special brass;
A split gear appeared in the design;
Valve crackers were replaced with imported ones, just in case; A shaft with "narrow phases" was installed: outlet - 66 degrees, inlet - 70, opening angles - 246 and 250 degrees, respectively. The valve travel is 9.5 and 9.6 mm. Our new motor remained "not plugged in" - the valves do not reach the pistons. When checked at the stand (the sensors were turned off), the result was not impressive.
If you install the engineering firmware, you can select the parameters "from and to". And then the picture looks better ...
All sensors, including the lambda probe, were connected in the latter case. We managed to remove 96 "forces" at 5300 rpm!
How not worth increasing the power of the VAZ 2114!
✔ Do not attempt to bore canals. This operation can be performed in the absence of ball cutters, but in garage conditions nothing will work even with cutters. The bottom line is that the accuracy of the cutter installation is important - the error should not exceed 1-2 microns. ✔ As you can see, on the stock VAZ-2114 hatchback, the power increase was 24%, and this is without installing a "chandelier", "improved exhaust" and other expensive elements. ✔ It makes no sense to buy a "racing camshaft" without a suitable tuning firmware.How to make tuning a VAZ 11183 engine
It is clear that the replacement of the ECU will be a mandatory step in tuning the 11183 motor. It's simple: you can't flash a regular M74 unit, but January 7.2 is a good and time-tested solution. We will also have to abandon the E-Gas option, which means that the throttle assembly and the receiver will have to be replaced.
The parts of the intake tract were borrowed from the 2111 engine. A cable pedal was installed, and the engine began to look human.
Everything works well with the January controller, but standard firmware- this is not an option if the camshaft has been replaced. And he, in turn, has the following parameters: The width of the release phase - 104; Intake phase width - 109; Outlet opening angle - 272; Inlet opening angle - 268; Valve travel (outlet / inlet) - 9.5 / 10.1 mm. After installing a new shaft, the motor became "plug-in". However, on the 2114 hatchback, the increase in power is almost always associated with a compromise. In this case, we had to sacrifice reliability. What's improved: Maximum torque increased by 14 N * m; Power also increased - the limit of "90 forces" was passed. By the way, any tuning leads to a decrease in durability. Make a choice.
Tuning 8 valve engine "with split gear"
The split, that is, the adjustable gear was not used in the last project. It is better to install it on "non-plug-in motors". Setting method: 1. The movable and stationary parts are marked with a mark, the same as on a standard pulley; 2. Installation is carried out in the usual manner, setting the crankshaft and the timing mechanism according to the marks (as when replacing the belt), you should also remember about the correct tightening torque of the belt; 3. If in the 4th cylinder the intake and exhaust valves are not open "to the maximum", we carry out the adjustment: we loosen the outer screws, and, holding the outer part of the gear, correctly align the camshaft. Tighten the fixing screws.Many motorists, especially beginners who have just purchased a VAZ-2114, thought about how the 8-valve injection engine installed on this car works. This article will discuss the design of the motor, the main characteristics, as well as dismantling and repair features. This information will be very useful for beginners and those who do not know how the main power unit works.

Characteristics of the 8-valve engine
Many motorists remember how at the end of the 90s of the 20th century and at the beginning of the 2000s, the VAZ 2108-09, which was also called "Samara", were popular on the roads of the CIS. These cars became legendary in that era. Due to the high popularity, the AvtoVAZ plant decided to resume production of these models with some modifications.
VAZ-2114 engine under the hood
First, the VAZ-2114 received a modified engine... In fact, this is the injection version of the Samara. Although she received some features from modern engines... If we consider in more detail, the Samara-2 engine (this is the type installed on the VAZ-2114) is a mixture of two engine options into one: from VAZ 2108 and VAZ 2110.
Many motorists liked the Samara-2 power unit and they fell in love with it. The main indicator was - ease of repair and inexpensive spare parts. Thus, the 8-valve engine has become the benchmark for the "price-quality" indicator.
When the basic information has been reviewed, you can go directly to the consideration of the characteristics of the motor.
Table of the main characteristics of the Samara-2 engine with 8 valves:
| Name | Characteristic |
|---|---|
| engine's type | Inline, longitudinal, 4-cylinder, 8-valves |
| Fuel type | Gasoline (installation of gas equipment is possible) |
| Arrangement of cylinders | 1-4-3-2 |
| Injection system | Distribution, injection type |
| Control | Bosch, January or GM |
| Camshaft location | Upper |
| Drive unit | Front |
| Diameter of piston and rings | 82 - nominal (tolerances by groups: A - 82.00-82.01, B - 82.01-82.02, C - 82.02-82.03, D - 82.03-82.04, E - 82.04-82.05) |
| Crankshaft | Cast iron |
| Cylinder block | Cast iron |
| Timing system | Belt and roller |
Disassembly and repair: basic facts
Therefore, consider the main operations aimed at removing the engine from the car:
- At the preliminary stage of disassembly, it is necessary, as well as coolant from the system.
- Another point that should not be overlooked is the blackout of the car. This is necessary in order not to close the system.
- Disconnect the fuel system.
- We dismantle the units that supply air to the engine.
- Disconnect the throttle, as well as all remaining air pipes and pipes of the cooling system.
- We dismantle the injection system and the receiver.
- We shoot completely.
- We disassemble the gas distribution mechanism.
- and a pump.
- Now, you can dismantle the manifold.
- Remove the pan, oil filter and pump.
- Disconnect the gearbox and remove the clutch. The gearbox can also be dismantled for convenience.
- Remove the cylinder head.
- We dismantle the power unit.
- We carry out the final disassembly.
Overhaul of the power unit will require more in-depth knowledge of the design and principle of engine operation, but if desired, every motorist is able to figure it out and carry out these operations with his own hands.
It is worth noting that when diagnosing faults, it is worth carefully and carefully examining every detail for defects.
conclusions
The device of the VAZ-2114 8-valve injection engine is quite similar to the first generations of this engine - "Samara". Of course, the designers made many changes to the features of the power unit, but in many ways they remained similar. Repair and maintenance of this engine must be carried out regularly, which, but will also reduce the wear of the parts that are located inside.
