The health of the car is extremely important for every car enthusiast. The failure of the next unit or node threatens not only unexpected breakdowns on the road, but also makes a serious blow to the wallet. Today we will talk about the heart of Renault Logan - her engine, and find out what it is fear of restyling owner with variations with 8 and 16 valves, and how often the oppressive piston group.
A bit of theory
The principle of operation of the engine is based on the belt drive, which connects the crankshaft and the camshaft, the cooling pump and the generator. The latter, in turn, manages the rockers, which lead certain valves at the right moment and ensure the intake and the release of the fuel mixture.
The belt of the gas distribution mechanism, or simply the timing, is made of a special rubber-like composition, which is capable of carrying friction, heating and operation at high loads for a long time. But from any rule there are exceptions, and stumble upon the defective belt or the item that has exhausted its resource, it is not so rare. And in this case, the belt connecting the shafts and the pump is broken.
What happens in this case? It turns out that the generator sharply ceases to feed the voltage into the cooling system, which leads to the operation of the radiator fan. Pomp sharply ceases to feed the coolant, and overheating occurs. But the worst thing happens at the moment when the camshaft stops rotating, and the pistons on the inertia continue their cycle.
Due to the inconsistency of these parts in the engine, the piston rushes to the valve and with force affects it. The valve is oppressed, and along with them the risk of rockers, pushers and piston themselves. After that, the engine is subjected to full bulkhead and overhaul.
Renault Logan 1.6 After restyling offers two engine variants: 8- or 16-valve design. The first of these issues 82 horsepower power. For each of the four cylinders here you have two valves, one of which works on the inlet, and the other to the release of the exhaust mixture. At the same time, only one camshaft shaft applies, and this repeatedly simplifies the design of the motor and reduces its repair, if the details of the piston group oppresses.
Second Engine on Renault Logan. 1.6 is a 16-valve design with two camshafts. Thanks to the use of 16 intake elements, the engineers managed to achieve more quiet and smooth operation, excellent dynamics and, most importantly, phenomenal power - on restyling it reaches 102 horse power. This design is more perfect and efficient, it will repair any element of the motor will cost the owner at least twice as expensive.
You never know what you can do till you try
It's time to move from theory to practice and turn to the opinion of themselves owners Renault. Logan 1.6 with 8- and 16 valves that already have experience in replacing certain components of the engine and know what surprises should be expected from the power units provided for restyling.
The eight-valve version of Renault Logan 1.6, as has already been said, is the most simple design that has only one camshaft. This means that for good job The motor, in contrast to the 16-valve, is enough to competent adjustment of just one camshaft instead of two. True, the reliable operation of the pump, the overheating of which can lead to the repair of a large number of expensive parts of the engine.
Does the piston group of the octal-valve power unit of restyling? As practice shows, the oppression, and quite often.
What is this due? First of all, the irresponsibility of the owners themselves and their refusal to follow the recommendations of the manufacturer. The discrepancy in terms leads to a rapid wear of the timelines of the timelines and the belt itself and will soon lead to its rupture. On the other hand, ignoring the characteristic whistling rollers, which indicates the need for their replacement, leads to a restyling to a similar effect and oppressive components of the motor.
The same applies to the restyling engine with 16 valves. The whole difference is that there are two camshafts on the 16-valve. This means only that the timing setting here should be even more careful, because two shafts must work synchronously on a strictly defined algorithm. In essence, even if one of the two camshafts of the 16-valve operates in the wrong phase, the valve is oppressed with the same success.
Summing up
Based on the practice of possession of restyling Renault Logan, it becomes clear that the engines on this car oppresses as often as on any other. However, the reliability of the motor itself has nothing to do with it. Strict compliance with the regulations and the timely replacement of components are able to save on the repair and renew the heart of the car to repair and repeatedly.
Replacing valves and so
How much will the repair cost?

Ohrenet at the service service ....
At the original domestic car, this cost is almost overhaul engine ...
I have a chain chain on shoal. And the repair came out about 8 tr., Despite the fact that I shot and put everything myself. Well, after this repair, she better did not, the chain was stretched every 500 km, put a new one ... and why it was shitting to repair, nor comfort neither amenities, and even break every 15 minutes.
pS Since then, five years have passed, now I suppose.

And there are not 16 valves for 1.4?
And another question, but why broke the belt? How long have changed? I just, according to the experience of that shah, in vain it does not break, maybe you should take my head with disassembly and put.
Toxa, did you buy a spare part for a long time in the store on "slake"? Good spare parts are the same as some and more expensive than on foreign cars :) Yes, there are positions that cost at times cheaper than it is, but for everything you have to pay ... For example, the DMRV stands on the VAZ how much? About 1000? On my old old woman more than 5000 ... But I know that I will put it and skip 250 thousand without any problems with him!
Prices in all stores are about the same, but on DMRV runs such because they are on the VAZ "... 004", "... 016", "... 037".
tell me. And what will be from 1.4 when the belt break
what did the engine repair the engine?
Replacing valves and so
How much will the repair cost?
Maybe it's easier to sell it what to mess with her?
My GBC is used in working condition to your motor. I am ready to sell for cheap and install in our service. Will be released in 2 - 2.5 cheaper than yours to do.
Each time before buying a car, we think about what is the volume of the engine, how many "horses" under the hood, what fuel consumption, compare the car in color, interior trim, as well as various exterior elements. Of course, these issues are important, but such a parameter is equally important as the drive of the gas distribution mechanism, briefly speaking the timing belt.
Reference!
The timing belt is an element of the engine that performs the function of the link between the crankshaft and the distribution shaft on any modern car.
Renault Logan Engine Options
Consider such an option that you are going to acquire, by all the folk car Renault Logan. Concerners concern Renault equipped cars (except top equipment) Two types of engine that have passed all sorts of technical tests and have indices of K7J, K7M, which speaks of motors of 1.4 and 1.6 liters 8V (valves), respectively. And the luxury car has a 1.6 liter engine, with a 16 valve "head" with the K4M index. In each of them, a belt stands in the form of a gas distribution mechanism. And what engine to choose in the material:
Now consider each engine individually and discerning, in which of them, the valves will be bend when the timing belt breaks.
K7J - 8 valve engine volume 1.4 liters (valve grid)
The most popular engine at the domestic consumer valve grottoes
Four-stroke four-cylinder gas engine K7J, evolved in our time straight from the 80s of the 20th century. Due to the fact that the motor is the continuation of the line of engines of the former generation, it has a clearly distinguished feature in the form of an outdated design with increased flow Fuel. However, this does not prevent him from remaining one of the most maintainable engines in the line.
On the this engine There are no hydrocomathers, so every 15-25 thousand kilometers it requires a procedure for adjusting the valves. And periodically occur the leaks of oil at the gland of the crankshaft.
Weathered 3 valves of 4
Some "Loganods" of this engine prefer his more powerful version K7m.
K7M - 8 valve engine volume 1.6 liters (valve berth)
Less popular 8-liter valve engine 1.6 liters - K7M
Motor K7M from Renault, constructively with its predecessor K7J is practically no different. The same liquid cooling and combined lubrication system. The same problem remains on the leakage of the oil and the absence of hydrocompensators - adjust the valve.
Bended valve
However, if you look at specificationsThis engine has a 10.5-mm magnified piston running (due to the fact that the height of the block is changed), as well as the greatest engine and flywheel.
Nevertheless, all the above-mentioned advantages did not help save the engine valve, when the timing belt is broken, they are neut.
K4M - 16-valve engine volume 1.6 liters (Navy valve)
Round valve on K4M engine
The distinctive feature of this "top" engine from the previous ones is two lightweight camshafts in the cylinder head and new piston system. From this power compared to K7M increased by 20 hp, at the same time increased efficiency and stability in the work. On the K4M motor, there is no problem to adjust the valves through a certain range of mileage, as the above-mentioned hydrocompenss are already present.
The GHM drive is still carried out with a belt and just as on previous engines, the valve bends during its cliff.
The reasons!
Timing belt can break for different reasons
Of all the above, we realized that on all types of engine engines of Renault Logan when the timing belt breaks the valves. And below, we describe the reasons why the cliffs occur at all and how to avoid it.
- Timing belt wear (low quality or technical wear), oil entering, etc
- Fit various foreign bodies under the belt
- Jars pump
- Jump or removes pulling roller (s)
- Enclosures crankshaft or camshaft
In order not to worry about the status of the timing belt, it is necessary to constantly monitor its external state, degree of tension, to replace according to the regulations or change immediately if there are any damage on it. To ensure that oil and other liquids do not fall on the belt (serves as the beginning of premature wear).
It was once a piston and part of the engine
If when the timing belt is closed, only the valve bent, it can be said that this is a great luck. In some situations, the pistons themselves may suffer with such a breakdown, the surfaces of the cylinders.
The symptoms and behavior of the car in which the timing belt replacement is necessary
As a result of elevated loads or wear of a connecting rod-piston group, the timing belt can jump on one round, resulting in. This phenomenon is a symptom to check the status of the belt and the correctness of its installation.
Repair cost
Specifically, in each situation, depending on the state of the engine, after it stops, due to the breakdown of the GDM drive, auto mechanics counted the cost of repairing strictly individually.
Given the usual example of the belt break in the K7J engine, the average cost of repair (with materials) will be released approximately 10-15 thousand rubles.
The valve mechanism operation occurs as follows: At the time of reaching the piston of the upper dead point, both valves are closed in the combustion chamber - it creates a certain pressure. Bridal belt leads to the fact that valve Do not have time to close before the arrival of the piston. Thus, their meeting occurs - a collision that directly leads to the fact that the valve bends. Earlier, in order to prevent a similar problem, special valve valve was performed on old engines. On the new generation engines, similar notches are also found, but they are intended only to avoid the valve deformation engine and when the belt break occurs, they absolutely do not save.
From a physical point of view, at the time of the breakdown of the timing belt, the camshaft stops, under the action of return springs that brake his cams. The crankshaft at this moment is inertially continues the rotational movement (regardless of whether the transfer was included or there was no, low revolutions or high, the flywheel continues to turn it). That is, pistons continue to work, and as a result - to beat the valves at the currently open. It is quite rare, but it happens when the valves damage and the piston itself.
Causes of timing belt
- the wear of the belt as such or its low quality (gears of the shafts have sharp edges or enter oils from the oil salts).
- crankshaft clinical.
- pOMP clinics (the most common phenomenon).
- clear several or one camshaft (for example, because of the coming to the disrepair of one of them - however, there are a little different consequences).
- the pulling roller is unscrewed or clins the rollers (the belt is weakened or hauling).
Modern engines, as they are more powerful, in comparison with their predecessors, have a much smaller and vitality. If we consider the cause, relying on the valve, this problem occurs due to the short distance between them and the piston. That is, if at the time of the arrival of the piston, the valve is properly, then its bend instantly occurs. Since for greater compression and compression in the bottom of the piston there is no groove under the valve of the required depth.
What motors of the valve jet?
On machines with 8 valve Engine Caresses less often, but 16 and 20 cl., Whether gasoline or diesel bend occurs in most cases. True, sometimes it can be one or more valves, and if the engine worked at idle, then it will break it at all. But there are few such cases, mainly the consequences of irreversible. The table with the list of engines on which the power of the valve of all popular cars when the belt is cutting the gas distribution mechanism.

How to find out the valve blows?
Does the engine check threatens if the valves bend after the timing break
In this matter, you will not help a visual inspection, nor the numbers given in the "Gnet of the Valve" tables. Even if you have information from the manufacturer about damage in the event of a belt break, it is not known how reliable it is.
If you wish, check the presence of the probability of the bend by the valve piston when the timing belt breaks, it is necessary to remove the belt, set the first piston at the VMT, turn the camshaft to 720 degrees.
If everything went well and he did not stop, you can continue checking - go to the second piston. When and everything is fine there, then the possible belt break will not lead to negative consequences for the engine of your car.
In order to avoid this problem (the bend of the valves during the breakdown), it is necessary to constantly keep the condition and tension of the timing belt under control. When the slightest unfamiliar noise appears when working, it is immediately necessary to try to find out the reason for its occurrence, inspect the state of the rollers and the pump.
When buying a used car, make an immediate regardless of what the seller told you. And then such an actual question as does the valve bend when There will be no disturbing.
Round valve signs
When the belt broke out, then simply by changing the timing strap, hoping that everything went without consequences and you start the motor, it is not worth it. Especially if the engine is in the list of those on which the valve turns. Yes, there are cases if the bend was not big and several valves ceased to fit tightly in the saddle, then you can turn the starter, but often such actions will further exacerbate the situation. Since with insignificant damage everything will work and spinning, but the engine will shake, and the consequences will only deteriorate.
Best of all, if you remove the "head" in order to check it clearly or bay Kerosin, however, there are several ways to check whether the valve without dismissing the engine.
The main symptom If the bended valves are small or completely no compression. Therefore, it is necessary in the cylinders. But, such actions are relevant if the crankshaft can be checked and nothing rests anything anywhere. So the first thing to do is installing a new belt, manually, for a bolt on a kV, scroll through a few turns all the gas distribution mechanism (you need to unscrew the candles).
How to check whether the valve bent
To determine if some valve rod melted, it will be enough for a literally five revolutions of manual turning key per crankshaft bolt. If the rods are integers, then the rotation will be free, beaten - heavy. And more should be clearly tangible 4 points (with one turn) resistance to the movement of pistons. If such absolute resistance, screwing back the candles, unscrew them in turn and scroll the crankshaft again.
In force on manual tapping, with a missing one of the candles, it is relatively not difficult to understand in what particular cylinder bend the valve (s) occurred. However, this method will not always be able to help accurately find out the valve or not.
If the crankshaft turns freely, then you can check compressometer. No such tool? So pneummont, and checking the tightness of the cylinders the most correct way that will give the answer as the valve plates in the seats are adjacent, without additional consequences when scrolling the starter and without installing a new belt.
How to check whether the valve itself will be?
For a pneumatic test, it can be unnecessary to pull the car on a hundred, you can find out, sealed cylinder or not. The easiest thing:
- pick up diameter candle well a piece of hose;
- unscrew the candle;
- install the cylinder piston into the upper dead point (valves are closed) by once;
- insert tight hose in the well;
- at all, trying to blow into the combustion chamber (the air passes - wondered, does not pass - "carried").
The same test can be done using the compressor (even automotive). True will have to spend a little more time, as you need to prepare. In the old candle, drill a central electrode, and a hose on a ceramic tip (fixing a well-clamp). Then swing the pressure into the cylinder (provided that the piston in it is worth the VMT).
Hitting and pressure on the pressure gauge will understand the valves hats in the saddles or not. Moreover, depending on where the air goes to determine intake bent or graduation. When curved outwards, the air goes to the exhaust manifold (silencer). If the inlet valves be bent, then in the intake path.
Renault Logan 1.6 8 8 valves appeared in our country with the first generation Renault Logan. Initially gasoline force aggregate K7M issued 87 horsepower, but today the same motor has a capacity of 82 hp There are no errors in this difference. The fact is that in 2005 the motor corresponded to the ecological standards of Euro-2, and today corresponds to the norm of Euro-5. The power unit was more environmentally friendly, but the reconfiguration was deprived of the Logan engine of several horsepower.
Technical characteristics of Renault Logan 1.6 8 8 valves
Working volume - 1598 cm3 Number of cylinders - 4 Number of valves - 8 cylinder diameter - 79,5 mm Piston stroke - 80.5 mm Drum drive - belt Power hp (kW) - 87 (64) at 5,500 am. in min. Torque - 128 nm at 3000 vol. in min. Maximum speed - 175 km / h acceleration to the first hundred - 11.5 seconds Fuel type - gasoline AI-92 Fuel consumption in the city - 10 liters Fuel consumption in mixed cycle - 7.3 liters Fuel consumption on the highway - 5.8 liters The engine has a large resource and completely unpretentious. The main thing in time to change the timing belt, which is perhaps the main thing weakness Motor.
Pluses of the engine K7M Renault Logan 1.6 8 valves
✔ low price and reliability of engines design; ✔ Reliability: a confirmed motor is more than 400 thousand km; ✔ Universal and maintainable; ✔ simple maintenance; ✔ have a high torque; ✔ It provides good "elasticity" of engines, equal to 1.83.Minuses of the engine K7M Renault Logan 1.6 8 valves
✔ relatively high fuel consumption; ✔ There is instability of revolutions when working on idling; ✔ In the design there are no hydraulic components, so it is necessary to constantly adjust the valve (after 20-30 thousand km); ✔ There is a probability of valve bending with a sudden breakdown of the timing belt; ✔ The crankshaft seals often flow; ✔ low reliability cooling systems; ✔ Very noisy and prone to vibrations.If everyone regulations Perform a timely and according to the manufacturer's recommendations, the engine resource can reach 400 thousand km, which is confirmed by real numerous examples. The only unpleasant surprise may be the breakdown of the timing belt, evidenced by reviews. In the case of such an accident, pistons face valves, causing their bend or complete destruction.
Engine Renault Logan 1.6 8 CL. petrol, four-stroke, four-cylinder, row, eight-block, with upper arrangement distribution Vala.. The order of the cylinders: 1-3-4-2, the countdown - from the flywheel. Supply system - distributed fuel injection MPI. The engine with a gearbox and clutch form a power unit - a single block fixed in motor compartment on three elastic rubber-metal supports. The right support is fastened to the bracket on the top cover of the drive belt of the gas distribution mechanism, and the left and rear - to the card of the gearbox. The engine cylinder block is cast from cast iron, cylinders are boring directly in the block. The nominal cylinder diameter is 79.5 mm. At the bottom of the cylinder block there are five supports of the native bearings crankshaft With removable covers that are attached to the block with special bolts. The holes in the cylinder block under the bearings are processed when the covers are installed, so the covers are not interchangeable and for differences are marked on the outer surface (the lids account is conducted from the flywheel side). On the end surfaces of the middle support, nests are made for a stubborn semi-colts that prevent the axial movement of the crankshaft. Inserts The root and connecting rod bearings of the crankshaft steel, thin-walled with antifriction coating applied to work surfaces. Crankshaft with five root and four rod cakes. The shaft is equipped with four counterweights, cast at the same time with him. To supply the oil from the root neck, the channels, the outlet holes of which are closed with plugs are served. In the front end (sock) of the crankshaft, the oil pump drive is an ascent pulley of the gas distribution mechanism (timing) and drive pulley auxiliary aggregates. In the hole gear pulley There is a protrusion that enters the scene on the sock of the crankshaft and fixes the pulley from turning. Similarly, fixed on the shaft and pulley of the drive of the auxiliary units.
Renault Logan Motor Lubrication Combined. Under the pressure, the root and connecting rod crankshaft bearings and the camshaft bearings are lubricated. Other engine nodes are greased by splashing. The pressure in the lubrication system is created by a gear oil pump located in front of the crankcase pallet and attached to the cylinder block. Oil pump is given chain transmission From the crankshaft.
The timing of timber on Renault Logan 1.6 8 valves is carried out according to the following scheme (the image is slightly higher) - the torque of the crankshaft pulley is transmitted to the pulley of the camshaft rotating the plot of the coolant pump. The belt is tensioned by a special roller, which changes with timing belt. In the event of a belt break of the valve. Therefore, in accordance with the Rules maintenance Car checking the status of the belt every 15 thousand km of mileage.
