Engine VAZ 21114 1.6 8v 80 hp: reliability, characteristics, service life, reviews, service, problems and price


The appearance of the Samara family (originally Sputnik) in AvtoVAZ production was a real breakthrough for the domestic automotive industry of that time. The three-door hatchback VAZ-2108, which debuted in 1984, created a real sensation among Soviet car enthusiasts. Stylish design, advanced production technologies, outstanding driving performance - all this led to resounding success. And this despite the fact that the body of the three-door hatchback clearly did not correspond to the utilitarian preferences of car enthusiasts of that time. The new model gained enormous popularity, and its design even received its own nickname – “chisel” – due to its characteristic silhouette.

In 1987, model 2109 was released - a five-door hatchback based on the V8. While retaining all its advantages and features, it was more suitable for the role of a family car. This only cemented the success. Later, the family was expanded to include a four-door sedan. With minor changes, the first generation remained on the production line until 2004.

The second generation of the Samara-2 family is, in fact, a restyling of the first generation models. The front part of the body was redesigned, the lighting equipment and some visual elements of the exterior design were changed. The interior also received changes in the form of a new panel (the so-called “euro-panel”), as well as improvements to some elements.

Line of power units VAZ-2114 (Samara-2)

During production, various modifications of engines already known from other models of the manufacturer were installed on models of the Samara-2 family. The widest choice was offered by model 2114, the successor to the legendary VAZ-2109 “nine”.

All engines that were equipped with the “fourteenth” are in-line naturally aspirated fours. The carburetor power system was gradually becoming a thing of the past, so the restyled successor to the “nine” is found exclusively in injection versions. This made it possible to modernize the engines and comply with environmental standards.

Engine 2111 (1.5 l., 8 valves)

At its core, the engine is a redesigned modification of the well-known 21083 unit, which appeared on the legendary G8. The processing affected, first of all, the food system. Instead of a carburetor system, the engine began to be equipped with an injection system. The design of the connecting rod and camshaft also received changes. All this made it possible to improve technical characteristics. Power and torque have increased. In addition, the engine began to comply with Euro-2 environmental standards.

Gas distribution mechanism with overhead camshaft and belt drive. Its nice feature is that if the valve belt breaks, it is not susceptible to damage.

Typical problems

Floating idle speed most often occurs due to malfunction of the following components:

  • Idle air control;
  • Throttle position sensor;
  • Vacuum booster.

If the existing symptoms are supplemented by the fact that the engine stalls while driving, then you should also pay attention to the condition of the mass air flow sensor (MAF).

If the engine begins to run unevenly and “triple”, then first of all you should pay attention to the compression indicators. Noticeably lower compression in one of the cylinders most likely indicates a burnt out valve. If the spread is small or exists in several cylinders, then the valve clearances should be checked. There is a high probability that they require adjustment. A similar symptom may also indicate problems with the gasket between the cylinder head and the cylinder block. However, even if such symptoms are not observed, do not forget to regularly check the thermal clearances of the valves, as well as adjust them. The manufacturer recommends performing this check every 20 thousand km. If everything is fine with compression, but there are similar symptoms, you need to check the ignition module.

Often noises and knocks become companions of this motor. All of this can be caused by out-of-adjustment valves. If you experience an increasing loud, dull metallic sound when you press the gas pedal, the engine will most likely need to be repaired. There are several main reasons for this symptom:

  • Knock of main bearings;
  • Knock of connecting rod bearings;
  • Knock of pistons.

The operating coolant temperature range for this unit is 95-103 degrees. However, there are often cases when the engine simply does not heat up to such levels. The main reason for this behavior of the motor is a malfunction of the thermostat. Some owners have to replace it almost on a regular basis. All this is a consequence of the low quality of spare parts.

Other common malfunctions of this engine

  • Valve cover leaks;
  • Wear of cooling system components;
  • Failures of the injection system on old copies;
  • Breaking off the fastenings of the exhaust exhaust pipe (can be treated by replacing the steel threaded connections with brass ones).

The engine is very common and deservedly popular among many car enthusiasts. Its simplicity, maintainability and good knowledge make it easy to cope with existing shortcomings and characteristic malfunctions.

The manufacturer officially declares a resource of 150 thousand km. However, practice shows that many specimens are nursed deep beyond 200 thousand km. A lot depends on operating conditions and attention to maintenance.

Causes of breakdowns and elimination

Thanks to the deep grooves in the pistons, the 21114 engine does not bend the valve, reducing the frequency of overhauls until the full service life of the piston group or rings is exhausted. However, there are smaller faults characteristic of it:

Knock when accelerating, uneven operationvalve clearances are offtiming valve adjustment
Oil leaks on the blockcylinder head gasket leakgasket replacement
Engine overheatingpump failurepump replacement
Increased gas mileageinjector malfunctiondiagnostics, replacement of parts of the distributed injection system

The motor does not cause any other troubles to the owner; it is considered very reliable and “resourceful”.


Replacing the cylinder head gasket

Engine 21114/11183 (1.6 l. 8 cells)

The unit is a continuation of the development of the motor with index 2114, and accordingly its progenitor 21083, which was installed on the first generation of the Sputnik/Samara family. The changes affected mainly the cylinder block. Its height has increased, and accordingly the piston stroke has increased. The working volume has increased to 1.6 liters. Performance in terms of power and torque has also increased. In practice, this manifests itself in the form of improved elasticity and greater traction. The modifications made allowed the engine to comply with Euro-3 environmental standards.

Car owners can call this engine different names. You can find such names as engine 2114 (out of habit with an 8-valve Euro-2 valve), “Kalina”, as well as those corresponding to the official indices 21114 and 11183. The differences between engines with these two indices are that they were produced on different assembly lines.

The huge similarity with the 2111 engine endowed this unit with almost identical problems and malfunctions. It is also necessary to regularly monitor the condition of the valves and combat uneven operation.

One of the unpleasant individual features is the noisy operation, similar to the sound of a diesel engine. With other noises, things are the same as in the 2111 engine.

However, despite the common roots and problems, experts note that 21114/11183 is still a little less capricious. At the same time, there is still no risk of bending the valves if the timing belt breaks.

The motors are also similar in terms of service life. Thus, the manufacturer indicates 150 thousand km before major repairs, but in practice the figures easily exceed 200 thousand km, and sometimes reach 300 thousand.

Tuning

  1. The easiest way to increase the power of a VAZ 21114 engine is to install a new lightweight camshaft, split gear and adjust the valve timing accordingly. This allows you to get an engine power of about 90 horsepower. Among other things, the behavior of the power unit at high speeds is improved.
  2. Maximum performance can be achieved by replacing the exhaust manifold, modifying the cylinder head and installing lightweight valves. In this case, the engine will produce about 115 horsepower.
  3. Further tuning is possible only with the installation of a compressor and turbocharging. However, in this case, the life of the engine is significantly reduced, which may require major repairs literally after 50,000 kilometers.

Engine 21124 (1.6 l., 16 valves)

The engine with index 21124 was replaced by unit 2112 on the conveyor. The sixteen-valve “four” increased its volume to 1.6 liters due to the use of a “high Kalinovsky” cylinder block. Modifications were made to comply with Euro-3 environmental standards. Thanks to this, traction at low speeds increased, but at the same time it became calmer in character. Compared to the “twelfth”, the noise level has increased.

The problem that was most feared by the owners of the sixteen-valve engine of the previous generation with index 2112 was solved. Thanks to the special design of the pistons with holes, the valves will not bend if the timing belt breaks. This is a significant advantage compared to the “twelfth”.

Thanks to the presence of hydraulic compensators, there is no longer a need to constantly monitor the thermal clearances of the valves. However, these parts are most often the cause of unpleasant knocking noises from under the hood. In addition, the cause of the knocking may be a problem with oil pressure. Moreover, the indicators can be either lower or higher than normal.

The old problem with valve adjustment was replaced by a new one. It is recommended to monitor the tension of the timing belt and tighten it every 15 thousand km.

There are also problems with knocking of a different nature. They can be called “branded” for VAZ engines. This is a knock from the main and connecting rod bearings, as well as from the pistons.

The engine is not without other “proprietary” faults:

  • Floating speed;
  • The engine “troits”;
  • Stalls at idle or while driving;
  • Temperature problems.

All these problems are familiar from other units. For example, for the same 2111. The roots of the problems are common, so the solutions can be found in the corresponding section of this article.

If the car does not start at all, then the check must be carried out according to the following scheme:

  • Starter and battery;
  • Ignition system;
  • Power supply system and fuel pump.

If there are problems with traction, and specifically with its decrease, you should check the pressure in the fuel rail, as well as the condition of the injectors. Perhaps their filters are clogged.

A characteristic feature of the engine was increased vibration. There can be many reasons for this. Among them are the idle speed regulator, high-voltage wires, spark plugs, and a lambda probe. And this is not a complete list. To identify the cause, you will need a high-quality diagnosis from an experienced technician.

This engine easily overcomes the standard resource indicators from the manufacturer of 150 thousand km. According to the experience of the owners, most specimens easily last more than 250 thousand km. In addition, in a secret rating this engine model is considered one of the most successful from VAZ. This becomes especially important for owners who prefer to tune and modify the engine of their car.

Advantages and disadvantages

Since the 21114 motor is already an improved version of the 2111, there are no obvious shortcomings here. The main “diseases” of internal combustion engines are:

  • intense heating of the pistons - there are no special nozzles for oil cooling; they will appear only in later versions of the manufacturer;
  • cylinder head – not suitable for other engines


Cylinder head 21114

The manufacturer recommends periodically monitoring the valve settings, since there are no hydraulic pushers in this internal combustion engine.

Engine 21126 “Priora” (1.6 l., 16 cl.)

A continuation of the evolution of VAZ 16-valve engines was the engine with index 21126. It is a development of 21124, but with some changes. Among them:

  • Lightweight ShPG (connecting rod and piston group);
  • Better surface treatment;
  • Honing of cylinders with more stringent requirements.

The timing drive is a belt drive with overhead camshafts. But unlike its predecessor, when it breaks, the valve bends. There is a radical solution to this design feature - replacing the pistons. If the engine is of a standard design, then you just need to carefully monitor the condition of the belt. Moreover, the problem with its weakening was solved by installing an automatic tensioner. The type of belt used was also changed.

Typical faults

If you feel a loss of power, then most often the reasons for this are the following phenomena:

  • Loss of compression due to a burnt-out cylinder head gasket;
  • Wear of the cylinder wall;
  • Wear of piston rings;
  • Piston burnout.

The result of unstable operation and refusal to start may be a problem with pressure in the fuel system. In addition, such symptoms are caused by sensor malfunctions, air leaks through leaky hoses or their connections, timing problems, or problems with the throttle valve.

If the engine is clearly “troubling”, then, first of all, it is necessary to check the compression readings to eliminate the problem of valve burnout. But more often this is caused by faulty spark plugs or a malfunctioning ignition coil. Sometimes the reason lies in the condition of the injectors, namely in the degree of their contamination.

Floating speed is a completely typical disease of VAZ 16-valve engines. Often, in addition to this, the engine runs unevenly. In this case, first of all, it is necessary to check the mass air flow sensor (MAF). If it is working properly, then most likely the cause is the throttle valve. It is necessary to clean it, and possibly replace its position sensor (TPS). At the same time, you should check the condition of the idle air control (IAC).

This engine was not without its signature headache with the thermostat. It also becomes the reason that the engine cannot warm up to operating temperature. However, if there is severe frost outside, perhaps the old-fashioned method of using cardboard in front of the radiator will help.

Some characteristic problems of other VAZ engines migrated to the 21126 Priora. So, if you detect knocking noises under the hood, you should first check the condition of the hydraulic compensators. Most often, they are the culprits of unpleasant knocking noises. At the same time, knocking noises that are associated with main and connecting rod bearings, as well as pistons, familiar from other VAZ engines, can also occur. This is already a serious malfunction, which is fraught with difficult engine repairs.

Minor problems, such as refusal to start, most often lie in the following malfunctions:

  • Starter and battery;
  • Ignition coil;
  • Candles;
  • Fuel pump malfunction;
  • Clogged fuel filter;
  • Faulty fuel pressure regulator.

Having improved its technical characteristics, the 21126 motor is still slightly inferior to its predecessor 21124 in reliability. Although it cannot be said that it is inferior very significantly. This is mainly due to the more complex design. Nevertheless, it is one of the best domestic engines, which also fits into modern environmental standards.

The declared resource is 200 thousand km. Compared to the officially declared resources of its predecessors, it has increased. However, in practice, older motors with a simpler design generally last longer. If we judge by reviews of actual use, then on average the actual resource corresponds to that specified by the manufacturer. Sometimes it can be more, sometimes less. Much depends on operating conditions and level of service.

Maintenance intervals

The 21114 engine is not capricious in operation, but consumables must be replaced according to the schedule presented below, as required by the internal combustion engine design:

Maintenance objectTime, months or mileage, km (whichever comes first)
Timing drive (belt)replacement after 50,000
Battery12/20000
Valve clearance24/20000
Crankcase ventilation24/20000
Belts that drive attachments24/20000
Fuel line and tank cap24/40000
Engine oil12/10000
Oil filter12/10000
Air filter12 – 24/40000
Fuel filter48/40000
Heating/Cooling Hoses and Fittings24/40000
Coolant24/40000
Oxygen sensor100000
Spark plug12 – 24/20000
An exhaust manifold12

If the user has tuned the internal combustion engine, the frequency of replacing some consumables is reduced due to intense wear of friction pairs.

Owner reviews

VAZ 2114 continued the tradition, and like its predecessor, it became a truly people's car. At one time it was the most affordable offer among non-mileage vehicles. This allowed it to become widespread and take its rightful place among other popular VAZ models.

Maksim. Lada 2114 1.6 l. 8th grade, 2010 180,000 km

I bought a car in 2015. The mileage on this example was quite decent, but the condition is good. I settled on the version with an 8-valve engine. Power is not so important for me, but they are considered much more reliable.

In general, this is confirmed so far. I only let you down once. When the temperature dropped below 30 degrees in winter, the battery died. But in fairness, it’s not entirely correct to make claims against the car itself.

Among the repair work, I did the replacement of the master brake cylinder and vacuum booster. We also had to change almost all the hoses under the hood. I recently had to replace the heater radiator. The rest is just consumables. I change the oil every 6-7 thousand, I only use synthetics. Many people do this on much higher mileages, but I like to play it safe. Moreover, given the quality of our fuels and lubricants, this will not be superfluous.

Among the shortcomings, we can note the quality of spare parts. Original spare parts from the factory do not serve flawlessly, but they have some margin of safety. Among the new ones there is a lot of different rubbish and defects. And this despite the fact that I try to buy the highest quality possible and not save. However, their “life” is very short. This is very frustrating and stressful. So I started thinking about selling.

Andrey. Lada 2114 1.6 l. 8th grade, 2008, 150,000 km

This car came to me unexpectedly. I was looking for a temporary second car for the family and settled on this option. I thought it wouldn’t be for long, but it turned out that I drove it for five years. All because I had to sell my main car. When purchased, the mileage was about 65 thousand.

There is not much to say about the ownership experience. A simple and unpretentious car. There are minimal amenities, but it doesn’t cause any trouble either. There is a minimum of electronics and electrics, and as a result it is quite reliable.

I didn’t have any breakdowns that would make it stand up straight on the road. I changed the clutch, replaced the timing belt and rollers three times (at my own request). Nothing more serious. I went for diagnostics a couple of times because the engine was not running very smoothly. Once we cleaned the throttle, and the second time we had to clean the injectors. I also replaced a rotten muffler.

Perhaps I would have kept it as a second car just in case, but it was starting to rot very actively. If not for this shortcoming, I would have given it a solid A. And so only four plus. For those who need a simple work machine for every day and are not too demanding, this is a very good option. The main thing is to find a specimen that is not killed or rotten through and through.

Nikolai. Lada 2114 1.5 l. 8th grade, 2006, 120 00 km

I purchased it in 2011 with 30,000 miles. The mileage is truly original, despite its age. I can say this for sure, since a friend had the car and was in plain sight all the time. I traveled for three years and did not know grief. I only changed consumables and all sorts of small things. But after the mileage exceeded 100 thousand, breakdowns began to appear.

First the stove stopped heating. Well, I thought it was a common thing: a thermostat or a faucet, but it’s not that simple. The antifreeze was slowly decreasing, but I thought it was coming from under the clamps somewhere, so I just added it little by little. Everything turned out to be much more serious. The temperature sensor was broken and was giving incorrect readings. That is, it showed normal temperature, but in fact it was overheating. It wasn’t actively boiling, but just a little bit at a time. Accordingly, the antifreeze gradually disappeared. As a result, such regular overheating gave me headaches. And minus the cylinder head gasket.

Then the ECU burned out. For some unknown reason. There is an opinion that the firmware is simply crooked. In the end I had to replace it. It cost, as they say, a pretty penny.

Well, little things somehow started to fall apart. And the quality of spare parts is absolutely poor. At least buy it in advance and rearrange everything around. Therefore, I sold it at 120 thousand. Perhaps I just came across an unsuccessful copy, because many people can easily ride for 200 thousand. But we need to clarify how much is being invested in repairs. I wasn’t happy with such fixed costs, so I decided to sell.

Judging by the mileage of 100 thousand, then everything is quite worthy, with the exception of corrosion resistance. Afterwards there is a big lottery. The car is suitable for those who love and know how to tinker themselves. The services turn out to be very expensive.

Design Features

After modernizing the 21114 engine taken as a standard, the 11183 engine has the following design nuances:

Cylinder head 11183

To reduce manufacturing costs, a connecting rod-piston group, a pulley and a crankshaft flywheel from the 2110 engine are installed in the engine. The volumes of the combustion chambers are increased for the engine with the sole purpose of ensuring a compression ratio of 9.6 - 10.0.

The manufacturer does not provide hydraulic compensators in this internal combustion engine, therefore, on the one hand, the use of lower quality oil is allowed. On the other hand, the savings in the operating budget when using cheap lubricants are “eaten up” by the costs of periodically adjusting the valves in a service station, since the manufacturer recommends doing it more often.

The main attachments are driven by their own belts. The design of tensioners (for example, a generator) leaves much to be desired. But the internal combustion engine allows you to increase power in the following ways. Moreover, a reasonable boost does not require major repairs to be carried out more often than the established deadline.

Belt drive of the generator
Even without improving the characteristics, the motor is high-torque and torquey, and produces 200% of the resource declared by the manufacturer. The available repair dimensions of the piston group make it possible to increase the service life, taking into account several overhauls, up to a million kilometers.

Removing the additional muffler

To avoid burns, it is recommended to start work after the exhaust system has cooled down.

We carry out the work on an inspection ditch or overpass.

We disconnect the pipes of the additional and main mufflers.

1. To separate the flanges of the pipe of the additional muffler and the catalytic collector, use a chisel to bend the edge of the locking plate of the lower nut and the edges of the heat shield that lock the other two nuts.

2. Using a 13mm socket with an extension, unscrew the three nuts securing the flange of the additional muffler pipe to the flange of the catalytic converter.

3. Remove the locking plate and heat shield.

4. Raise the additional muffler and remove the front muffler bracket from the rubber cushion

5. Similarly, remove the rear muffler bracket from the rubber cushion

6. Remove the flange of the additional muffler pipe from the studs of the catalytic collector

7. Remove the sealing gasket

After each removal of the additional muffler pipe flange from the studs of the catalytic collector, the sealing gasket should be replaced with a new one.

Install the additional muffler in reverse order. After installation, you should lock the nuts securing the pipe flange and catalytic collector by bending the edges of the locking plate and the heat shield.
