Laying the head of the cylinder block (GBC) is a device 3 in 1. After all, it can simultaneously compact three motor systems: cooling, oil and gas distribution.
Accordingly, the requirements for qualitative indicators of this gasket increased.
Defense device
Engine modern car Very complex mechanism and consists of various interrelated nodes. In the cylinder block, there is a crankshaft with a connecting rod-piston group, it is covered with a head of the cylinder block, in which the valves and the gas distribution mechanism are located.
This design is created for the convenience of the engine repair and maintenance, and between them is our gasket. It is necessary for sealing the cavity of the cylinders, the cooling system channels and the lubrication system channels.
The service life of the entire engine depends on the reliability of the insulation of these cavities. We should not forget or try to save when repairing. The gasket is designed for one-time application, so at any repair, it is necessary to replace the gasket to the new one.
The GBC laying compacts the connection site of the cylinder block and its head.
Types of designs
- Bepassed - manufactured out composite materialscharacterized by a small shrinkage and the ability of the material itself to recover.
- Asbestos and tale asbestos - Looks like their properties on blessing, the same elasticity, heat resistance, elasticity. Currently applied in most car motors. Their base is a fibrous fire-resistant material asbestos, cooked in the form of a thin sheet. For the adoption of strength, it is additionally reinforced with a metal mesh or perforation from the steel sheet, then a ready gasket is cut out of the resulting sandwich. The gasket must accurately repeat all the planes and channels of the cylinder head. As the contour of the combustion chambers, oil canals And other thin jumpers asbestos gaskets are additionally edged with a thin layer of soft metal. Such a metal edging significantly increases the mechanical strength, increases the density at the joint of the cylinders, which makes it possible to significantly increase the resource and the degree of engine forcing. To reduce the properties of the sticking of the gasket, its surface is additionally treated with graphite lubricant.
- All-metal strips Made from thin sheets of soft metals - aluminum, copper, soft steel. They are considered to be most effective, with such a gasket there is a uniform distribution of pressure and temperature over the entire stationary plane. Used by diesel engines trucksengines air cooling, as an additional gasket to reduce compression.
Causes, signs of malfunction GBC
No manufacturer will definitely say when the gasket fails - it can serve as decades, and can bring in the most inappropriate moment. Durability is directly related to the operation mode and its observance.
The main reason for breakdown is overheating, it can happen due to the cooling system malfunction or due to very intensive operation at the limit of motor capabilities.
Overheating leads to deformation of the block of cylinders and the head of the block, upon subsequent heating, the gasket is no longer so tightly adjacent to the planes, as a result, the loss of elasticity occurs and the inevitable leakage of gases from the combustion chamber begins, which can fall into the cooling and lubrication systems.
The second most popular reason is the wrong tightening of the bolts when installing the GBC during repair. Another reason is wrong installed ignitionwhich leads to detonation and cylinder ignition, which accelerates wear as a piston group and block gaskets.
Signs of design failure:
- The presence of leaks of oil or antifreeze on the outer jack of the CBC and the cylinder block.
- At the probe level of oil, emulsion traces of coolant are visible, the oil level is higher than usual - it happens when the tightness is loss between the lubrication and cooling channels.
- Exhaust white color On the heated engine - a signal about attacking antifreeze to cylinders, a drop in the level of the liquid in the expansion tank of the car.
- Footprints of oil in an expansion tank - a sign of oil entering the cooling system through a punctual gasket.
- Bubbles in the cooling system and radiator.
- The deterioration of the engine thrust on all turns.
These signs are not always indicators for replacing the GBC gasket, it is possible a malfunction elsewhere - this is just a reason for careful engine diagnostics.
It should always be remembered that the belated replacement of the gasket can lead to expensive repair as row-piston groupand to repair the head.
Product replacement procedure
So, leaks are detected, our actions. First, if there are no explicit signs of damage to the gasket, you can try to further stretch the bolts for fastening the block head.
It happens that after that flowing leaves, and the node serves another thousand kilometers.
If it happened strong overheating or the gasket is badly damaged, then a replacement is necessary.

USEFUL ADVICE
Remove the head of the cylinder block is more convenient with the assistant, as it is rather heavy.
- ... Then remove its gasket.
- Tighten the bolts on the cold engine in the specified order in four stages:
Stage I (pre-sediment pads) - Tighten the bolts with a torque of 20 N · m
(2 kgf · m), after which it is belugged to an angle 100 ° ± 6 °. Make an excerpt 3min;
Stage II - release bolts 1 and 2, after which they again tighten them with a point of 20 N · m (2 kgf · m) and end the angle 110 ° ± 6 °;
III stage - release bolts 3, 4, 5 and 6, after which again tighten them with a point of 20 N · m (2 kgf · m) and end the angle 110 ° ± 6 °;
IV Stage - release bolts 7, 8, 9 and 10, after which they again tighten them with a point of 20 N · m (2 kgf · m) and end the angle 110 ° ± 6 °.
- Install all the details and nodes, except for the cylinder head cover and the air filter, in order, reverse removal.
- Adjust the tension of the gas distribution belt (see "Checking the tension of the auxiliary aggregate drive belt").
- Believe me and, if necessary, adjust the gaps in the valve drive (see "adjusting the gaps in the valve drive").
- Set the cylinder head cover (see "Replacing the gasket of the cylinder head cover").
- Install the air filter (see "Removing and installing a air filter").
- Fill the cooling fluid (see "Replacing the coolant").
In general, it should be understood that the replacement of the gasket under the head of the cylinder block is a rather complicated operation that requires certain skills and special tools.
The cost of its replacement is also high enough, so it is easier to prevent failure than then to repair.
It is necessary to monitor the level of coolant, the health of the cooling systems and the engine temperature.
Use only quality lubricants And antifreeze are not aggressive to aluminum alloys. It is also necessary to monitor the health of the ignition system, to use the gasoline of the necessary brand.
Motor vehicle - This is a rather complicated and technological unit, which consists of a large number of nodes that perform their narrow functions, which, as a result, convert the combustion process of combustion into energy mechanical, which is capable of driving a vehicle. In other words, that would be filled into the tank fuel turned into motion, you need to use many nodes and aggregates, which every car enthusiast should know.
The GBC is called the head of the cylinder block, which is essential from vehicle nodes, which is responsible for controlling the combustion procedure of fuel in the motor and the output of exhaust gases. It is possible to highlight the main parts and mechanisms of the GBC:
- Block head or crankcase body, in which there are cooling system channels, all mechanisms, combustion chamber and oil pipeline.
- Holes with planting plane or thread for installing nozzles or spark plugs.
- The combustion chamber where the working mixture is flammable.
- Block head gasket.
- Drive gas distribution mechanism.
- Gas distribution mechanism.
- Threaded fasteners and planting planes for graduation and intake manifold.
Replacing the cylinder block is a rather responsible and laborious process, it is carried out to replace the gasket or to install new valves and sleeves. However, it is not necessary to contact the auto repair shop at all, you can replace the cylinder head yourself, having minimal locksmith skills and tools:
- Mandrel for pressing bushings.
- Mandrel for pressing oil recovery caps.
- Micrometer for the valve valves and guide bushings.
- Mandrel for crimping bushings.
- Scan for 8.03 millimeters, to deploy new bushings.
In addition, it is desirable to have an electric tile that is endowed with closed heating element. Before pressing the sleeves here you can heat the heads.
Also do not forget about the device to fix the valves when paving the springs. For this, a small board with bottles or something like that is suitable for this.
CHBC, work on dismantling GBC, step-by-step instruction
As a rule, the replacement of the cylinder block is not carried out. The process begins with replacing asbestometallic or thin metal gasket.
When the leaks are detected, cooling fluid or motor lubricant, I do not have to think long. It lies the reason just in this gasket, which you need to replace. However, at first it is necessary to get to it.
- From the battery, disconnect the mass.
- Correctly install the first cylinder piston - to the position of the first time.
- We merge the coolant.
- If the vehicle is still hot, in the power system it is necessary to reduce the pressure.
- Disconnect the fuel tube from the collector.
- Remove the cylinder head cover.
- Then find and disconnect the wires from the regulator full flow air.
- Next, we relax to the throttle node clamp of the airconducting fitter.
- Remove the element with the air filter housing.
- Do not forget to replace the air intake hose.
- We find and turn off the screw, which fixes the pipe holder of the water pump pipe.
- We assign to the bracket and weaken the clamp.
- From the throttle unit, disconnect from the throttle assembly and liner hoses of the cooling system.
- Now weaken the clamp, which fixes the brake hose to the fittings.
- We divide all the wires from the position of the valve flap, idle and oil level controls.
- We find and disconnect from the ignition candles the ends of high-voltage wires.
- From the receiver pull the harness of the wires.
- Remove the camshaft drive belt, after removing its cover. It is very important in this case not to rotate both shaft before mounting the drive belt.
- Disconnect the plastic holder connecting the component of the oil and fuel frame.
- Soak and remove the cd fastening bolts. Do not forget that the cylinder head fastening bolts are turned only on the engine, which did not work for several hours and completely cooled.
- Remove the head. This element is quite heavy and it is desirable to remove it with an assistant.
- Now we clean the flushing surfaces of the GBC, they must be clean and dry.
- Of threaded connections We remove the oil, since otherwise back assembly Cracks may appear in the GBC, which will negatively affect the work of the vehicle.
Gasket GBC, types of pads, which choose
The GBC laying is necessary to strengthen the connection site of the cover and the head of the cylinder block. The gasket of the GBC should be changed with each replacement of the head of the cylinder block. It is important to understand that the gasket of the GBC and the usual laying of the lid of any element are different things.
It is responsible for such motor systems - gas distribution, lubrication and cooling system, therefore, the requirements for it are appropriate. In no case cannot save when replacing this gasket. If the symptoms of its wear are noticeable, the gasket should be replaced immediately.
There are several types of pads:
- Beszasbestos - high reproducibility and low collapse.
- Asbestos - elastic, plastic and heat-resistant.
- Metal - the highest quality, however, along with it, and the most expensive.
So, to replace the gasket gasket is necessary in the following cases:
- With signs of leaks of oil.
- If you have noticed a foreign mixture of a muddy white when checking the cavity of the oil - getting a coolant as a result of a worn gasket.
- If you have noticed white smokewhich comes out of exhaust pipe.
Installation of gasket GBC
Installation of gasket GBC - the process is very simple. You just need to install a new head laying on the block on the installation bushings, but do not forget to align it on the guides. GBC collect B. reverse order.
GBC, installation of cylinder
Naturally, the GBC installation is carried out in reverse sequence to the removal. Special attention should be paid to fastening bolts. The tightening of these bolts must be carried out only with a torque wrench.
If there are small experience and knowledge, these work can be carried out on their own. However, it is necessary to understand the process itself and possess knowledge about the design of the GBC.
All units and vehicle components need constant maintenance, diagnosis and repair. Cylinder heads are no exception. Elements that are loaded mostly require increased attention to themselves. These are elements of the gas distribution mechanism - camshaft seals, valve glands, cylinder head gasket and others. On the proper work GBC and premature wear of parts have its influence the mass of factors, the main of which concern diagnosis and maintenance.
Tightening the nuts without observing the points of the effort controlled by a torque wrench, disrupt the order of nuts fastening or tightening bolts cannot be, as it can lead to the curvature of the head housing, which is able to remove the motor.
Removing and disassembling the head of the cylinder
Order procedure
The head of the cylinder block is removed from the engine assembly with intake and outlet manifiers.

Details of the valve mechanism.
The head of the cylinder block (GBC) is one of the most important nodes car Engine. From how it is installed and adjusted, the operation of the motor, its stability, reliability and efficiency depends on.
In our article we will tell how quickly and without special spending to independently install the head of the cylinder block on the VAZ family cars.
The first condition is correct and reliable installation GBC is cleanliness landing. Carefully clean the plane of the block on which the GBC is placed. Cleaning is first carried out by a sharp object, and then with special car cleaning agents that will help remove the residues of antimony, oil.
Pay special attention to the holes in which the studs are screwed. They fall into them, water, garbage. And then, when the GBC is attracted by stiletto to the block, they can make microcracks in the cylinder block due to the fact that when screwing the studs, excessive pressure is formed. When the motor is heated through these microcracks, produce gases, gases are trying to lay the gasket between the GBC and the block, and the water from the cooling system will go to the oil. Overhaul The engine is provided! And it is B. best case. Therefore, it is recommended to thoroughly check the holes before screwing the studs and be sure to get into it, taking a clean rag and using a screwdriver to get to the bottom.
When the location for the cylinder head is cleaned, proceed to the installation. Installation of GBC begins with proper Installation Gaskets, which is located between the GBC and the cylinder block.
The block holes must clearly coincide with the laying holes, only in this case its installation is considered correct.
And the head of the cylinder block should be well cleaned from nagar, dirt, oil, toosol. If there are suspicions that the GBC was overheated or other influence, which led to deformation, then it is checked on special device And then, if necessary, polished.
When installing the GBC, it happens that the gasket "moves", so follow it.
The GBC is considered to be established in place when she "stood up" on the guides, and the hoses, wires do not interfere. After that, start the screwing procedure. In order not to confuse the bolts, they need to be labeled in advance. The inner bolts are smeared by oil, so they are difficult to confuse with outdoor, it will be a kind of tag.
If you do not have a pneumatic or power tool, you can fasten the GBC bolts to the old, kind knocker.
The bolts are only intimidated by the bolts, but do not finally be delayed, there is a special, dynamometric key. Only with it will control the correct tightening moment, which is recommended by the manufacturer.
The second moment of the tightening should not exceed 8 kg. The order of the tightening remains unchanged, from the center to the edges, in pairs. After the bolts are tightened by 8 kg, we carry out two trust, both 90 °. First we pass the bolts for the first time, turning the dynamometer key 90 °, then the second time.
After the final tightening, the head of the cylinder block is considered mechanically installed, but not yet working. So that it turns out to be a worker, it is necessary to connect all the "perfyri", i.e. Hoses, nozzles, and so on. It is recommended immediately to return to it to it, connect the temperature sensor wire and set the timing tag.
After proceeding with the installation of valve glasses. Before installing, they are necessarily cleaned from dirt and lubricated. Clean and blurred glasses should easily become in place.
In order not to confuse the sequence of planting glasses, removing them, they are positioned in a certain order. After installing the glasses, be sure to smear the "bed" to which the camshaft will then fall.
Something useful for you:
The lubricated and pure camshaft is placed in place. You can fix it immediately with the gland. Experienced locksmiths in order to simplify the process of setting camshaft marks, sometimes the Dedovsky method is still used. During the installation of the camshaft, the first and third camshaft neck must look at you.
Then we set the camshaft cover. Lubricate the places where the camshaft will lie (bed), and do not forget about one nuance. At the ends, you need to remove the old sealant, and put a new one, then it will be well kept oil.
By setting the second part of the cover, repeat the process. Now I'm caught in nuts, and do not forget about the washers that should be under each nut.
The tightening torque of the camshaft caps should not exceed three kilograms. Experienced repairmen over time can produce tightening process without a dynamometer key. Then the tin protective cover is placed.
Then we put the gear camshaft, but before that make sure that you have not forgotten to put on the camshaft, which holds the gear from scrolling.
Bolt firmly fix the gear in its place. Be sure to make sure that the labels on the gear and CFC coincide.
Then we throw the timing belt, but it is recommended to put a tension roller. Install a special washer in front of the roller. You should not forget that the video is not worth tightening to the "madness", it should be bludging freely on the rod.
When dressing the timing belt, do not forget to check the coincidence of labels on the camshaft gear and on crankshaft shaft. When the timing belt is dressed, by twisting tensioner roller We achieve the desired belt stretch.
After tensioning to the desired indicator (the belt turns around its axis by 90 °), we tighten the smoothly control nut.
The next tribler, which needs to be properly installed in the grooves. It is necessary that after installing a traver in the grooves, the alignment of shafts was observed. Between the rubber and the GBC we mount the fuel pump, without forgetting to lubricate it with a sealant. So that the rod does not run into camshaft, it needs to squeeze a screwdriver. The housing of the gas station drive hexagon is dragged.
By pressing the housing with a slightly hexagon, I am intimidating the nuts and attract evenly. Then we already tighten the "seriously" hexagon. We establish a finally a rubber, which we have just tried out. Do not forget about sealant, which will exclude the leakage of the oil. Do not forget about the bar on which there is a ignition timing, because after starting the motor, it is possible to need to adjust the traver. We once again check the connection of wires and pipes, which forgot, connect.
Latest Barcode - Installation valve cover and leather belt timing. After completing all the works and checks, do not forget to fasten the throttle cable into place. GBC installed and ready to work.
Video: Installation of GBC VAZ. Step-by-step instruction
Here you see a bunch of iron, which is assembled in a very necessary and convenient mechanism for you - your car. Look and reflect on the fact that people have created such an aggregate, but suddenly it can happen that because of some small detail the car will stop riding. Information about when the replacement of the GBC laying will be not superfluous for any car owner. Even if you and you will not repair your car, you need to know what can lead, if you do not replace the GBC gasket.
What is the GBC gasket
This item is used to compact the place where the cylinder and cylinder block is connected. Do not compare the concepts such as the cylinder head laying and laying the cylinder head cover, which is made of rubber. Let these concepts are almost the same, but there are differences.
GHC gasket performs three actions at the same time - This is the seal of the engine cooling system (channels), seal oil system Motor (Channels), and a sealing of the gas distribution system of the engine (cylinder cavity). It is because of this, the requirements for this detail are high. No need to forget and try to somehow save on the repair of the GBC or the cylinder block. The gasket is the part that is used only once, and with any repair of the engine, replacing it on a new one is required.
What are the types of gaskets GBC:
1. Besas missing - Such gaskets are distinguished by low shrinkage and high material repaid.
2. Asbestos - Such a type of pads are similar in characteristics with blessing, possess such properties as: elasticity, heat resistance and elasticity. This type of pads are most often used as remklects.
3. Metal - This type of pads is considered the highest quality and efficient. When using such a type of pads, a more uniform distribution of specific surface pressure is occurring at a junction area throughout the plane of the GBC and the block.
When the cylinder gasket is needed
Replacing this item may be needed at any time, and how much it will not know. There are some signs of the exit and the system of gaskets of the GBC, which we will list below:
1. There is an external leakage of engine oil, or a coolant.
2. When checking the oil on the dipstick, the blessed color liquid is noticeable - it may be possible to appear due to the falling coolant through the failed gasket.
3. If there is white smoke from the exhaust pipe all the time, not counting the car warming up, then, most likely, the cooling fluid has fallen into the cylinder.
4. If during the inspection expansion tank or on the surface of the liquid in the radiator there are stains of oil, then most likely motor oil Enters the cooling system due to bad gasket.
5.
And the last sign of faulty laying is hitting exhaust gases The cooling system, which appeared bubbles in the radiator, or in the expansion tank. All these signs of faulty laying are not accurate confirmation. But still you can not pay attention to them, as it will still need to be replaced by this detail. No matter how we avoid this moment.
Sequence of work when replacing the gasket of the GBC
Almost all the brands of the machines are the operation of replacing the gasket GBC is the same. But there are some features, such as the order of tightening the clerk attaching bolts and adjust the protracted torque of these bolts. These figures are specified in the manual for your car. If you do not have a manual, you can use the Internet network, and find this data. It is extremely important before the start of the promotion of the hbz mounting bolts, to clean them so that the keys do not happen to prevent the formation of a bolt's slot and the impossibility to unscrew it. Split fastening bolts start from the middle or first evenly turn all the bolts by 0.5-1 turnover.
Before starting work, you need to disconnect all attachments. And the order of dismantling itself is best to marry or designate schematically. By unscrewing the bolts, it is necessary to remove the block head and replace the GBC gasket. To center the gasket itself and the head of the block, usually, on the block itself there are sleeves. After that, make the installation of the GBC and all attachments in the reverse order. Especially for this moment you sketched the scheme. Tightening the GBC bolts are in a strict order with the drawing for this block, and it is necessary to follow all the parameters of the protracted torque that the manufacturer is specified. To do this, use a dynamometer key.
Main points when replacing GBC gasket
Not depending on some features related to one or another engine, type of pads and fastening bolts, there are norms and the rules of which it is worth sticking. The rules that need to know when replacing the gasket of the GBC regardless of the brand of the car. We will not tire you in detail, what bolt and how to spin. All the subtleties of the gasket replacement of the GBC are listed in the manual precisely to your type of motor. Before repairing, they should be read. It is very important to try to fulfill all the described requirements of the manufacturer who relate to the collection and parsing of the CFC.
1. When disassembly, you need to keep the marker in your hands. When disconnecting everything hinged equipment, in particular pipelines, do not need to be lazy and hope for memory, it is necessary to marry everything. Collect then will be much easier.
2. When you buy this item to replace, you must make sure that it is suitable for the power of the torque that the manufacturer of the motor writes to tighten the cylinder bolts.
3. Before promoting the fastening bolts, you need to clean them very well from the plaque. If the key breaks, then you may be injured, or the bolt's slope will be disrupted, which is why it will come to drill.
4. The promotion of the fastening bolts begin with a middle of 0.5-1 turns. It is necessary to remove the voltage.
5. After you have fed all the necessary work related to the replacement of the GBC laying, you can start everything to collect back. Everything needs to be done carefully and neatly.
6. Tightening the hbz fastening bolts only need to be done using a torque wrench, while following all the rules and parameters.
After you have gathered a GBC, all attachments need to put on their places, according to your scheme. After repair, for some time you need to citement to the above-mentioned signs. If everything is fine, then the gasket of the GBC you replaced correctly.
Features you need to know when replacing gaskets
As with any other works with your car, you will need a lot of attention and accuracy. In some brands of cars may not be friend On a friend of fastening and docking technology, but in general, all actions are needed to be practically the same and similar (universal for all cars):
1. Of course, for a start, you need to disassemble everything, while noting every item, regardless of whether it is necessary to forget anything and no extra detail appeared.
2. Buying a new gasket you need to make sure that it corresponds to all the characteristics, and in particular the torque that is suitable for your motor.
3. After the old gasket is replaced, set the head of the cylinder block should be made with accuracy by guides.
4. How to unscrew, so twist the bolts need very carefully, so as not to thread the thread and gradually distribute the voltage to all bolts.
5. And the last, the main thing is not to forget, consolidate all the details correctly.
We produce a replacement of gasket GBC yourself
Already, we previously mentioned the moments of replacing the GBC laying, but now we will clarify something. To identify, replace the GBC gasket is not difficult. Just everything you need to do everything very carefully to damage anything. It is impossible to split bolts, because they will not keep the cylinder head. The troubles of this kind are not needed by anyone. Before starting work, you need to read the instructions for the operation of the machine, find out everything that can be useful. If there are no instructions, you can read information on various car forums.
Say a little about bolts. Before promoting bolts, they need to be cleared of dirt, gary and other raids. After that, start unscrewed how to do it was previously described. Dismantling the head of the cylinder block cannot be started when attached aggregates. You need to jump all the belts, filters and appliances. But do not forget to sketch, write or photograph to the phone. Once lifted the head you can replace the gasket. According to the bushings, you put the gasket smoothly.
All that you need to do is put the GBC in place and all the rest of the equipment, and then tighten the bolts. It is advisable to do this using a dynamometric key. If you are not confident, then the best breaker for you will appeal to the workshop, where everything will be done quickly and efficiently. The cost of such work is rarely very high. We wish you success!
