No one will argue that most modern cars are programmed to aging. And for a sudden. If the Solaris engine is not subject to repair, why, who is to blame for that, in this case, do and what to do to prevent the accelerated wear of the motor, let's try to figure it right now.

Anyone who produces cars is interested in selling them as much as possible as possible, with minimal investments. Höndai is not an exception, especially for budget solaris. In the design of the car there are many fairly cheap solutions, inexpensive materials and technologies.. This engine concerns, including.

Official opinion

Officially, Höndai gives a guarantee on the engine without hinged equipment one hundred thousand miles or about 180 thousand km, and this is about five years of operation. Of course, it is far from the fact that the engine will scatter on the 181st thousand, because we know people who go on solaris 250-300 thousand, but there is one factor that cannot be avoided by anyone.

On solaris installed engine Gamma G4fa. Volume 1400 Cubo in or G4FG-G4FC. With volume 1.6 L..

A distinctive feature of motors of the development of the early 2000s is considered to be widespread use of aluminum, in particular, the use of this metal for the manufacture of the foundation of any motor - the cylinder block.

Engine Gamma G4FC.

On the one hand, aluminum is much easier cast iron, which is already practically not used to build blocks, it has excellent thermal conductivity. On the other hand, Aluminum is very plastic and less wearless than cast iron. It is precisely this that makes doubt on the possibility of holding overhaul, which will be relevant on mileage under 200 thousand km.

How do the engine overhaul on the Solaris?

High degree of wear when contacting two aluminum parts (piston and cylinder walls) cause engineers to invent all new means to prevent rapid wear.

Often the cast-iron sleeve is pressed into the cylinder blockwhich wear out more slowly aluminum. But there are other methods, for example, on expensive high-forsted cylinder wall engines are subjected to chemical treatment with nickel and silicon carbide to obtain a durable wear-resistant surface or rolling the cylinder mirror and the surface with a high silicon content is obtained.

The impossibility of boring

These are very effective, but expensive techniques, besides, it is often impossible to settle such a cylinder under repair size.

Gelzovka block of cylinders.

Engine Gamma. received aluminum block With stipulated in it thin-walled cast iron sleeves. It would seem that this is the same technology that should have been allowed to spend the capitals with time - settling the cast-iron sleeve under the repair size, install a repair kit from the pistons and rings of a larger diameter and wind the kilometers further with the renovated block.

Engine problems on Hyundai Solaris

The problem is that the wall thickness of the sleeve does not allow a boring, the sleeve is almost impossible to get from the block and replaced (it is flooded with aluminum at the production stage), and Hyundai did not provide for the possibility of producing repair spare parts, rings and pistons.

Ideally, each block of cylinders with wet sleeves (surrounded by a water jacket) have the ability to replace the sleeve, and the Gamma motor is dry, that is, tightly fixed in the block.

Repair "in theory"

Already crushed cylinders under the sleeve.

Theoretically, the replacement of the sleeves in our motors is possible, there are car services that are taken for it, the whole thing in price. After all, you can buy a new block of cylinders and it will cost in the amount comparable to buying a quarter used solaris.

The question arises about the feasibility of buying a solaris in the secondary market - in any case, sooner or later the cylinders are extended and then the engine will again light up the capital.

When the engine is not subject to repair at a solaris?

Diagnose the motor status is quite simple. This will tell both the mileage on the odometer and quite objective symptoms:

Simplicate "Disposable" engines

To some extent, the Gamma engine is still disposable, but it is not alone. Motor of the first Skoda Fabia, atmospheric Brz. 1.2-1.4 liters, also uses aluminum block and thin-walled cast iron sleeves, recent volkswagen Motor EA211 TSI It is necessary to understand the same technologies and manufacturers - they are little interested in reliability and half-million runs, they need to sell maximum techniques at a minimum cost.

Video about the lack of engine Hyundai Solaris

The owners do not remain anything except to closely monitor the state of the engine, use high-quality fuel and oils, sparing the motor in the heat and in winter, do not pull with the adjustment of the valves and comply with the service regulations. Only so you can maximize the engine resource. Durable all run and smooth roads!

Car Höndai Solaris gained great popularity worldwide. And this is not strange, because the car is inexpensive, but at the same time it looks great and performs its functions. Of course, there are certain problems, but without them anywhere.

By minus machines often include engine operation. In general, today the view is popular that all cars are made so that in 5-10 years they will have to be changed, and as an example, hend the familiar to us Hyundai Solaris with his "aluminum" engine.

Owners of the domestic "Zhiguli" hundreds of times heard the word "Tipital". The meaning of this process is to protect one of the most expensive parts of the machine from wear - a block of cylinders.

Under capital repairs still since those times, when Zhiguli appeared, imply the restoration of old cylinders by the method of their boring to the required size.

Also under these understood the replacement of the sleeves. Next, the craftsmen installed the pistons of the required size, and these details were made by the manufacturer of the car itself. Motors could have up to 5 different repair sizes, so the engine could be "rejuvenated" several times.

In such cars, cast iron was used to produce the cylinder block, this is a heavy matter, but it is very strong and easily bred. More difficult repairs began when companies began to produce blocks of cylinders from aluminum, this allowed to reduce the weight of the car, but I was demanding "Capital".

Aluminum cylinders

Such a material as aluminum is not so durable, compared with the cast iron, and with friction of pistons with a block, a plastic material can simply "grab". Therefore, engineers make a lot of effort in order to eliminate even minimal friction of aluminum surfaces.

In addition to covering the piston of the engine, almost always the cylinder of the aluminum block is simply isolated from the piston. In particular, for this, the "wet" of the cast iron sleeve is used, it is installed in the block and processed by the coolant, from which the part and the name is called. Repair of construction with "wet" sleeves is not complicated, because the block can be disassembled if necessary, and replace worn items. True, there is a system and cons, it is a smaller block of block and bad vibration-acoustic indicators.

For this reason, the engines for modern cars are most often equipped with thin-walled coatings or inserts that isolate the piston from soft aluminum.

On the sports car, the coating "Naizil" is used, it is strong enough, but it is expensive and the repair of the engine with such a coating will be difficult. It is clear that because of the high cost, Höndai Solaris manufacturers do not use such material.

Motor features Solaris

If we talk about Hyundai Solaris, and his Gamma engine, then in it aluminum parts are protected from abrasion by piston due to the thin hyelze of cast iron. This solution is very affordable and provides protection.

the engine, the same sleeves use the Germans from Volskwagen in their new TSI turbo engines. It is worth noting that such a sleeve is not inserted into the blocks of cylinders and simply complied, the liquid aluminum fills the part.

A large disadvantage of systems with "dry" sleeves is that their repair is often impossible, the manufacturers did not think about such technology, and there are no corresponding pistons and repair sizes on the market.

If it is easier to speak, then with strong wear of the cylinders, their replacement becomes the only way out. This item is very expensive, and if a person buys used Höndai Solaris, the purchase of cylinders will also add to the cost of about 30%.

Just aggravates the problem information about the planned resource of the engine Hyundai Solaris is only 180 thousand kilometers. True, this information is quite controversial, because there are no objective data that would regulate this issue, and the real resource depends largely on the operating conditions of the car.

In the reviews, the owners also disagree in opinions, some say that cylinders really need to be changed after 160-180 thousand runs, and some quietly departed more than 300 thousand km.

But such doubtful characteristics of the motor say that it becomes the third or fourth owner of the Car Hyundai Solaris really risky.

Of course, if the car drives several years, and after that it will have to be thrown away, then such machines are not needed by anyone. Accordingly, the question of whether the repair of aluminum blocks is possible, causes a lot of disputes. Even in the absence of clear factory repair technology, some masters are taken for this business and commit "Capital", after which the car will still calmly drive a couple of hundred thousand kilometers.

When need to do kapital

It is clear that no one will send the car Höndai to the dump, and in the absence of factory technologies, you will have to trust the repair of the engine to the masters with a service station. Only the question remains open when it is necessary to overhaul, because they say the reviews of the owners of Hyundai Solaris, this moment comes in different ways and depends on the operating conditions of the car.

In fact, some signs will be testified about the need:

• Low compression, large oil consumption and the presence of a dark gray exhaust;
• Low oil pressure and unnecessary sounds from a crank-connecting mechanism;
• When cylindro-piston elements or longitudinal crankshaft circulation were already worn. True, it can be defined only with special equipment in the car service.

Usually, this repair has to be conceived when running at 160-200 thousand kilometers. But it is worth considering that the ability and service life of the Höndai engine depend on the quality of the road surface, damage, the style of driving the owner and other factors.

Stages of major repairs

It is necessary to understand that the restoration of the engine of the Höndai engine is a very difficult procedure with which not everyone will cope. To make a overhaul independently, you need to understand the design and principle of the engine operation, have special tools and skills.

If you even a little doubt that you can handle this task, it is better to overpay, but still entrust the work by specialists, because it can be done only worse.

The process of overhaul engine is divided into several stages:

1. At first, the wizard remove the motor and then disassemble it. When removing the engine, it is necessary to do everything neatly so as not to damage all sorts of hoses, tubes and other elements.
2. The next step will be cleaned by all motor nodes.
3. Next, the masters inspect the degree of wear of the nodes in the Höndai Solaris car.
4. Defect. It is important to prepare technical documents in advance that compare current data with standard parameters and permissible deviations.
5. Repair GBC. At this stage, experts eliminate all cracks, set new or repair old guides and chamfer valve saddle. Also, the installation of new oil-circuit caps and camshafts.
6. Repair of the block of cylinders. At this stage, boring and abrasive processing of cylinders are carried out, as well as the replacement of the sleeves, seelings of cracks and other operations.
7. Next you need to restore the crankshaft.
8. At the end, you should collect and install the motor back. It must be done very carefully so as not to forget about connecting all connectors and connections.

After repairing the engine of the car Hyundai, you need to turn on the motor and give it to work in idle mode so that all the details are started and worked fine.

Why do you need to contact professionals?

DIY repair can only harm, it is better to entrust this business to those skilled in the art, the following advantages of contacting the car service are also talking about this:

• You can choose a hundred per specialization. There are many different workshops, and some of them specialize in Korean cars, so Hyundai Solaris's overhaul is better to entrust them;
• Masters experience. Any repair work that concern the motor is very complex, so the experience of specialists plays an important role here;
• Guarantee.

Motor cylinders are very expensive parts of the car, so the restoration requires a warranty that the repair service will be able to provide.

Engines with a working volume 1.6 (G4FC) of the GAMMA family from 2010 are installed on many cars of the concern. First of all, these are folk pets Rio and Solaris, but almost the same motors put and continue to use on Hyundai Elantra, I30, Creta, as well as Kia Rio X-Line, Ceed and Cerato. Moreover, you can select GAMMA I and GAMMA II generation motors. The first were installed on cars Rio and Solaris from 2010 to 2016. The second generation is still used.

Since the second generation engines have changed slightly relative to the first, we will tell about the design as a whole.

Gamma Series Engine Design

The engine gasoline, four-stroke, four-cylinder, row, sixteenthly populated, with two camshafts.

The cylinder block is cast from an aluminum alloy according to the Open-Deck method with a single casting of cylinders free in the upper part. In this case, the inner surface of the cylinders form thin-wing, flooded in the production process, cast-iron sleeves. The crankshaft is made of high-strength cast iron, with five root and four rod cakes. The shaft is equipped with four counterweights executed on the continuation of the two extreme and two medium "cheeks". Pistons made of aluminum alloy and have a short lightweight skirt. Piston rings have no high height. The piston finger turns into the piston bosses and pressed in the top head of the rod. A non-changing gasket is installed between the block and the head of the cylinder block.

In the top of the cylinder head, two camshafts are installed. One shaft leads inlet valves of the gas distribution mechanism, and the other is the final. A feature of the design of the camshaft is that the cams are pressed on the tubular shaft. Valves are powered by camshafts through cylindrical pushers. The drive of the camshaft - the chain from the sprocket on the crankshaft sock. Used hydromechanical tensioner chain. On the engines of different generations, the gas distribution phase control system is used, that is, changes in the moment of opening and closing the valves. The GAMMA I generation engines have a change in the position of the camshaft of the inlet valves, and on the second generation - on both camshafts.

Motor power system is a distributed fuel injection. On each candle installed an individual ignition coil.

Myths and reality

1. Engines are made in the PRC, and therefore the quality is not very. The engines are really manufactured in China, but it is more important that the production of motors has been established at the Hyundai Motor CO plant, and therefore quality guarantees the famous Korean manufacturer. Please note that even some premium cars, such as Volvo models, are collected in China, including their flagship S90.

2. Engine cylinders aluminum, disposable and unrepretentious. In fact, the design of the cylinder block allows you to replace the sleeve on new thin-walled cast iron, so that the engine can be engaged in the engine several times. Moreover, the price of such repairs is often comparable to the cost of restoring the engine with the cast-iron unit, provided that the pistons leave the previous one (and there is such an opportunity in some cases).

3. The crankshaft has a design of everything with four counterweights, and therefore bends stronger than, for example, by VAZ "transverse" engines. Yes, in terms of engine design, the Korean shaft is experiencing heavy loads, but the practice of repairing such engines with large runs shows that the wear of indigenous and connecting rod necks is usually minimal, and the case is limited to installing new nominal liners.

4. Engine resource - 180,000 km, after which the motor can be thrown out. Practice shows that with good care, some engines pass 400,000 and more kilometers. Only I recommend changing the engine oil more often - every 7500 - 10,000 km, fuel fuel on branded gas stations and prevent engine overheating.

5. Lightweight and shortened pistons quickly begin to hang out in the cylinders. Yes, of course, the design of the pistons is not the same as the "millionnies" of the eighties and nineties of the last century, but relatively inexpensive repairs with the replacement of pistons and rings, as well as the defective and repair of the GBC on mileage of 200,000 km, can significantly extend the motor resource.

6. The timing chain drive is not particularly reliable. Until 150,000-200,000 km, the chain usually goes without special complaints with good oil and a relaxed ride style. The multi-row toothed chain is very good and sometimes the asterisks bend stronger than the chain.

7. The absence of hydrocompensators creates a lot of problems to the owner.According to the maintenance regulations, the valve adjustment should be carried out at least than 90,000 km of run. The real need for adjustment usually comes a little later than the specified period. Another thing is the engines operated on gas. Here, the gaps really need to follow more carefully. In general, savings on the hydrocompensators - indeed minus this motor. And, which is the most offensive, at the ancestor, the engine G4EC Hyundai Accent of the first generation, the hydrocomathers were.

8. Phase pazers have an unreliable design. In fact, there are a partial character on phase hospitals, and even then only when the oil is untimely replacing the oil or at its low quality.

9. Noisy operation of the motor, especially noticeable at idle.Yes, there is a characteristic "dragonment" of fuel injectors, not particularly pleasant ear, but this is the only loud sound published by a working motor.

10. The destruction of the ceramic block of the catalytic neutralizer displays the piston group of the motor. The ceramic unit of any catalytic neutralizer in our operating conditions is indeed not very durable. If the neutralizer is placed far enough from the motor, then there is no danger for the latter. Such a layout is used by some automakers (for example, Renault), but not Hyundai. When painting, the pieces of ceramics of the neutralizer can really fall into cylinders and damage the work surfaces. The destruction contributes:

• The accumulation of unburned fuel in the ceramic block due to ignition interruptions.
• Mechanical damage site of the production system and sharp thermal blows when overcoming puddles.
• The use of low-quality fuel and a large number of additives for fuel.

Real Motor Disadvantages Hyundai 1.6

Most of these flaws do not have real reasons. They can be considered myths. The real miscalculations in the engine design Hyundai is not so much. This is the need to adjust the valves due to the lack of hydrocompensators and the inappropriate location of the catalytic neutralizer for Russian operating conditions.

conclusions

Engines with a working volume of 1.6 liters of the Hyundai / Kia concern with distributed fuel injection are one of the most trouble-free in the domestic market. Only the motors designed in the last century can be considered more reliable. For example, K4M RENAULT concern. But the characteristics of motors of those times are noticeably modest.

Mythical and Real Motor Problems Hyundai and Kia

• Prevention, timely maintenance and addition - here is the key to a long service life of the car!

In the forums often accumulating at the city that, Hyundai Solaris - the car "Chinese" and disposable, ride five years and throw out, after which the authors usually roll in decades, they say, now all disposable, the price is horse, and Maasdam's cheese is not the same. I even intrigued me, is it a competitors or "Disposability" of Solaris with some kind of scientific basis?

At Hyundai Solaris and related to himKia Rio, as well as CEE'D, ELANTRA and a number of models of the alliance are put by the engines of the familyGamma. Version 1.4 of themher the G4FA index, 1.6-liter engine - G4FG / G4FC. These engines have an aluminum block of cylinders, and all doubts are related to this.

When the motor is running, the cylinder block naturally flashes that at large runs leads to known symptoms: compression is reduced, oil consumption increases, and the pickup falls, cold starts are complicated. If you have made some "Zhiguli" to overhaul, then you know the recipe from this ailment: the cylinder boring under the repair size with the corresponding piston replacement on the so-called repair (their diameter on the line of millimeters is greater). The boring restores the desired form of the cylinder, and the repair pistons provide the factory clearance. Other cars had four repair sizes - a capital, how much will fit.

Problems began when strong cast iron blocks of cylinders began to be intensified with aluminum. Aluminum itself is an easy and thermal conductive material (this is a plus), but it is also rather soft and has a bad tendency to be seized upon contact with the aluminum of the piston. There are a dozen ways to solve this problem, but the essence in all cases is one: on the surface of the block (sometimes piston) this or that coating with high hardness is created. But it just complicates the boring blocks.

In addition to cast iron sleeves, wet or dry, chemical hardening of the surface layers of the cylinder is used or special coatings. For example, the cylinder block is cast from a siliceous alloy, and then etching aluminum on the surface of the cylinder mirror, resulting in a layer with a high solid silicon content (technologySILUMAL). In high-affilized engines covered with materialNicasil. (Nickel and silicon carbide), which came from motor racing: it is distinguished by fantastic hardness and wear resistance, although sulfur is afraid.

Accordingly, the maintainability of the aluminum block of cylinders depends on the technology of its manufacture. For example, nicosilene cylinders are almost not boring under the repair size: the alloy is very solid, and the coating thickness is small. Most often, for engines with such cylinders, the pistons of repair size is not available, but they are durable, which confirms the experience, for example, Porsche.

Silmal cylinders can be crowded, but to restore the surface hardness of the cylinder mirror, you need to comply with complex technology. But in general it is possible.

If you return to motorsGamma on Solaris / Rio, that they seemed to be the most maintainable technology with cast iron sleeves, which ensure the surface hardness of the cylinder mirror. The only problem is that it is not easy-graded "wet" sleeves, popular on old engines, but thin-walled "dry". In the manufacture of a block of cast-iron sleeves "fill" with liquid aluminum, as a result of which they, as it were, are swapped into the thickness of the block. Extract them is mechanically difficult, although the craftsmen are in private are taken. Theoretically, the cast-iron sleeve can be crowned, but in motorsGamma. The walls of cylinders are thin, and the manufacturer did not provide for such an opportunity: no repair sizes, no repair pistons.

The question of the maintainability of such (not only solaric) engines causes stormy disputes in the forums, and this is connected with what. Often, the "official" technology and the corresponding parts does not exist, that is, the plant does not provide for the possibility of repair. On the other hand, there are masters who develop folk methods, however, there are already talking about the Kustachin, and judging its quality for the eyes is difficult: it all depends on the master, technology, degree of wear. I admit that in other cases it is possible to revive the block, in the other renovated engine serves for a short time. Naturally, no guarantee of speech does not go.

In the case of Solaris, the problem is exacerbated by the shortness of the block: the hardness of the cast iron is lower than, for example, with an expensive Namille, and in some appears the value of the Solyaris Motor's resource in 180 thousand km. This, as you understand, is frivolous: five to six years of operation. In fact, the issue of the resource is very controversial, because at least depends on the operating conditions, and the declarations of 300-thousand runs are found in the forums of Kia and Hendvodov. It is possible: if you change the oil in time, do not turn the engine and spare it in the frost, you can save a resource. I guess, the value of 180 thousand km is a certain minimum strip that the manufacturer focused when creating a motor - I did not find any official comments.

By the way, Kia and Hyundai give a record car warranty for Russia - 5 years or 150 thousand km, and this warranty is fully valid on the "iron" engine without attachments. I do not exclude that after this period, the wear of cylinders may be critical for quite natural, programmed reasons.

If the block wear has reached the limit, it is changed assembly. I can not call the budget for new prices, but according to old prices it would have happened in the area of \u200b\u200b60-70 thousand rubles without work. That is, very funny.

Along the way, the question of the delights of used cars again arises. I will not generalize, but if buying a newSolaris. there is no questions, it is more complicated with the fauna: a copy with wear, close to critical, and in a couple of years you will get to replace the block. Moreover, it is not about a probabilistic breakdown, but about a completely natural and inevitable process.

What is interesting, in the engines of the familyGamma. There is another constructive feature - the lack of gap hydrocompensators in the timing, therefore, once in 100 thousand km, it is necessary to exhibit the gap between the cam and the pusher. Sometimes the owners ignore this procedure, which can also affect the resource. However, the Nissan engineHR16DE. Also does not have hydrotherapists, so "Solaris" is not unique in this aspect.

And on the image of "one-time"Solaris. works and the fact that motors seriesGamma. produced in China. Although this, I would not put it in a minus, because there are no messages about some frank "Chinese" in the motor: the assembly is neat and fully complies with the standards of Koreans (and these standards are very high).

Well, the final question - why? Why do manufacturers produce such motors? I think this is another victim on the altar of progress. Motors themselves Gamma series very perfect, especially by the standards of the medium-valued segment. In the West, they are produced including with a direct injection of gasoline and supervising (thank God, we have passed the bowl), and in all versions are distinguished by a high level of forsing - in fact, one of the best for class. Depending on the model atmospheric 1,6-liter "Gamma" for Russia, 123-132 hp are issued. and differ in good economy. They have changed phases of gas distribution, and many technically complex solutions, for example, expensiveDLC coating on valve pushers and compression rings with chromium nitride coating. In pursuit of ease and the technological content of the cylinder block, apparently, and donated its maintainability.

But it is logical from the point of view of the company that earns on the primary sale of cars. Her task is to offer a good car for the first buyer, and in this aspect I thinkSolaris. excellent machine. As for durability in the Old Testament sense of the word, it is in principle no longer included in the priority of most manufacturers. Environmental norms are tightened more often than people are ready to change cars, and therefore people need to push it ...

PS: Let not the impression be the impression that Hyundai / Kia is traveling in this matter. In fact, a lot of "disposable" engines is quite a lot, and sometimes engines of different families can be hidden under the same marketing index, one of which can be repaired, another - no. For example, the reputation of the "disposable" deserved the ignorant motors of 1.2-1.4 l in Skoda (BBZ) with aluminum blocks and gray cast iron sleeves. The factory technology is no boring, but in general it is sometimes done using after special pistons of third-party manufacturers. A similar design of a block of cylinders from a new Nobolksvage family, but I did not find information about their maintainability. The engine came out relatively recently, before Kapitilka, I think, no one has yet been run.

Malfunctions and repair of the engine G4FA 1.4 l.

The G4FA engine refers to the Gamma series, which was published in 2006 and replaced outdated Alpha motors. Gamma includes a number of motors, the most famous of which is 1.4 liter G4FA and 1.6 liters. G4FC, collected on one cylinder block, but we will focus on the younger representative.
The engine is based on an aluminum cylinder block with cast-iron sleeves, in which the crankshaft with a piston is 75 mm, long connecting rods, pistons with a peculiar dispenser and a height of 26.9 mm.
Covering this block aluminum 16-valve head with two camshafts. The Solaris / Rio 1.4 engine is equipped with a gas distribution phase change system, but only on the intake shaft, in addition, there are no hydrocomathers on the G4FA engine, therefore, once in 95.000 km you need to adjust the valve gaps if the situation requires that.
Comparing with the old Motors of the Alfa series, the G4FA uses a timing chain with a tensioner, which over its official resource does not require maintenance. And indeed, in practice she is pretty reliable.
The inlet has a single-stage ordinary receiver, without various length change systems.

In addition to all well-known cars, Hyundai Solaris and Kia Rio, this engine is placed on Kia Cee'd II, I20 and other transport in a slightly deformed version - by 100 hp.
On the basis of the G4FA motor unit, a 1.6 liter engine of the GAMMA series - G4FC was developed. Later, other close motors appeared: G4FG, G4FD, G4FJ and L4FC.
Motor release was stopped in 2018 and instead now they put a 1.4-liter option from the Kappa family.

Problems and disadvantages of Kia Hyundai G4FA engines

Many are interested in what engine manufacturer Hyundai Solaris / Kia Rio, so it is produced on the Beijing Hyundai Motor Company, yes the engine is Chinese, but do not hurry to scream "trash / fall apart / junk ...", let's clearly look at the shortcomings and the main fault G4FA, and then We conclude:

1. A knock in the engine Rio or Solaris. If your knock with warming disappears, then most likely, this is a timing chain of noise (in 90% of cases as follows) and not worry about anything, if he is heard and hot, then the problem may be in non-regulated valves, it can be incorrectly adjusted on factory. Contact the service and put them in order.
2. Noise. Sounds in character resembling clicks, cloaks, rigging, etc., this is the normal operation of the nozzles and do not know how to otherwise.
3. Butter lodges. It happens not often, nevertheless, the valve cover is not perfect and traces of oil signs of this. Change the gasket and drive further without problems.
4. Floating speed, uneven operation of the engine Rio / Solaris. The problem is solved by cleaning the throttle, if it does not help with fresh firmware.
5. Vibrations at idle. The cause of this phenomenon is a dirty throttle or candle. Clean the damper, change the candles and rejoice in pleasant operation of the engine. With strong vibrations, look at the engine support.
6. Vibrations on medium revolutions. This arises about 3000 rpm and no one knows what the reason, Hyundai-Kia official dealers speak about the characteristics of the engine and this is true. On these turns, the G4FA motor is included in the resonance and thanks to the original design of the engine fastening, all the vibrations are on the steering wheel and where only you can. Give gas or release the pedal, the motor will come out of the resonance and the vibration will disappear.
7. Whistle. Patient theme, whistle appears due to the weak tension of the generator belt, change the tensioner roller and disappears everything.
8. Eating butter. The problem relates to motors since 2011These power plants are not too reliable catalyst and due to poor-quality fuels (especially concerns regions), it has a property failure after 50 thousand km. In the process of its death, ceramic dust enters the cylinders and forms the loops in the cylinders. As a result, we have a high oil consumption and the need to make a overhaul with a sleeve block. Exit: either pouring very good fuel, or knock out the catalyst.
This problem does not apply to the first engines with the graduate collector "Barbus Rog".

Despite the stated motor (not less than 180 thousand km), over the years of operation, these motors have shown themselves very well, they have a resource at least 300 thousand km. The main timely service and use of good oil.

One of the fastest, simple and cheap ways to increase the power is to calibrate the engine. The offices are promised after chip 110-115 hp, try for the experiment, but do not wait for significant changes. Better let's see what you can do with your motor.

G4FA 1.6

A more efficient tuning option is to increase the volume of G4FA to 1.6 liters. To turn this scaffold, you do not need to change the cylinder block, it is the same as on a 1.6-liter engine, the heads are as the same except in the intake camshaft.
To build a row, you will need a G4FC crankshaft with a piston stroke 85.4 mm, short connecting rods from G4FC and pistons from G4FC (they are with a deepening, to reduce the compression ratio). After installing all this, you need to flash the computer. For the total transformation into G4FC, add to this intake camshaft from G4FC.
All this will give typical 123 hp

To go even further and get 130+ hp, you need to install an intake manifold from G4FG with variable geometry. To do this, you will have to spend some strength and money on the receiver, the VIS system control unit and the probe from G4FG with the guide.
If we started talking about G4FG, then his intake camshaft will be deposited and at certain modifications, it rises to your motor.
To all of the above, you can add a cold inlet, normal spider 4-2-1 and exhaust on a 51 mm pipe. After setting up, all this will give you about 140 hp
