Changed the gasket GBC machine starts. What you need to know about replacing the cylinder head gasket - we study together. Why pierces the gasket of the GBC

Not always, after replacing the GBC gasket, the engine begins to work without complaints - sometimes new problems appear. What unpleasant phenomena may occur in what the reasons for their appearance, and how to eliminate the problem that has arisen - we will tell in this article.

Possible malfunctions after replacing the gasket are as follows:

• engine Troy,
• the car does not start,
• white smoke exhaust pipe,
• knock of hydrocomathers.

Consider individually each of the faults.

Engine Troats

If, after replacing the GBC gasket, the engine is troit, it can occur as a result of the following reasons:

1. If the gasket is not installed correctly, or a low-quality laying itself. It is necessary to remove the installed gasket, inspect and make sure that there are no microcracks or other damage (). If the layout state is normal, then it should be reinstalled, otherwise - to install another part.
2. Clogged or defective nozzles, which, by the way, need to be changed during the repair associated with the GBC. Among the new nozzles can be caught by defective specimens - to exclude such a probability, you can try to put, for the test, shot old nozzles and then listen - the engine troit or stopped.
3. The insufficient level of compression in the cylinders can cause engine trimming, after replacing the gasket of the PC. Here you will learn -,.
4. Faulty hydraulic pins. Here, the recommendations are the same as in the case of nozzles - with each repair associated with the GBC, the hydraulicers should be changed to new ones.
5. Not adjusted idling or ignition - such a problem most often happens to the old domestic cars. Here you will learn -,.

The car will not start

Another problem that occurs after replacing the gasket GBC is the inability to make a car. Possible reasons Next:

• Marriage gasket, or installed not correctly. To verify this, dismantling and inspection of the gasket is required.
• Insufficient compression level in cylinders.
• Wear oil-giving rings.
• Runner wear in the ignition distributor, resulting in a spark of ignition. Remove the rubber and inspect it, for the integrity of all its components.
• Ignition is not adjusted.

White smoke exhaust

If, after replacing the gasket, the GBC, from the exhaust pipe of the white smoke, then this may be a consequence:

1. Cracks on the head of the cylinder block. It is possible to remove the crack only with welding in the service, if it is not big, or it may generally need to replace the entire head.
2. The thick white smoke coming out after the warm-up of the engine can appear as a result of antifreeze in the cylinder block - when the coolant is seeping through the worn seals or the GBC gasket.
3. In the design of some old cars there is a valve with a vacuum hose for the engine. When it goes white smoke, then this may be as a result of the fact that, through the valve mentioned, oil flows from the gearbox. And then the spark plug is contaminated and the failure of one of the cylinders. To exclude such a development of events, you need to check this valve and, if necessary, replace the new one.

Knock of hydrocompensators

It happens that after replacing the GBC laying, the hydrocompenss are beginning to knock. Some causes of the knock:

• If the knock of the hydraulic components occurs only during the start of the engine, then this is possible as a result of what happens somewhere motor oil. This is normal if, after replacing the gasket of the GBC, the car has not been operated for a long time and stood. Usually the flow is stopped by itself.
• If the knock of the hydraulic components occurs only during the warming of the car, and when the revolutions increase, it disappears, then the reason can be either contamination or the wear of the check valve. It is possible to fix the problem, respectively, either cleaning or replacing the hydrocompensator. When cleaning, you need to simultaneously change the engine oil.
• If the knock of the hydrocompensators occurs only on the hot engine, and it is all normal to the cold - it probably came into a malfunction of the plunger pair, and it is necessary to replace it.

Why the hydrocompensators are knocking: the causes and elimination of the problem - this is dedicated

Conducting repair work related to the head of the cylinder block requires special care and accuracy. Since one incorrect effect may adversely affect the operation of the motor as a whole. Therefore, often domestic car owners are faced with such a problem when the machine does not start after replacing the gasket. How to be in such cases?

What problems may arise

After replacing the hosts faced malfunctions of various kinds. Among them:

• the machine does not start after replacing the gasket;
• troit engine;
• from the exhaust pipe comes out white smoke;
• during ride, hydrocompensators were caught.

All of these faults indicate any problems in the system.

Does not start cars

If the engine does not start after replacing the element, there may be different reasons for it.

The repair and replacement of the gasket must be engaged when there is experience and you know how to install the item correctly.

Causes and ways to eliminate

If the car does not start, the reasons may be the following:

If, after performing these actions, the engine starts, then in conclusion, Ignition should be set. Do it according to the manufacturer's recommendations specified in the service book.

Troit engine

Troit Motor - motorists face such a problem after changing the sealing element of the head of the cylinder block. What to do in such cases?

Causes and methods of elimination

• Motor troit from poor-quality gasket or from an incorrect installation. It is necessary to disassemble the gasket and make it a diagnosis visually. If cracks or damage are visible, the component should be replaced.
• Wrong compression level. Sometimes incorrect compression in the cylinders can cause engine trimming. Check the level and, if necessary, adjust it.
• Output of hydroletakers. Professionals recommend changing the hydraulicers after each parsing of the cylinder head. Replacing the GBC sealer is no exception.
• Non-working nozzles. Experts advise to replace the injectors when dismantling the GBC and other types of heads related to the head. If they were changed, but the engine is still a troit, then perhaps the nozzles fell by defective. Install the old ones and then listen, the engine troit or not.
• Ignorated ignition or idle. This is relevant for old cars. Sometimes after dismantling, the GBC is knocked down idle and ignition. The problem is solved by adjusting both ignition and idling.

Putting hydrocomathers

Credited hydrocompensators - such a fault is characteristic of vehicleon which the dismantling of the GBC was performed.

Causes and elimination

It comes white smoke from exhaust

White smoke from the exhaust pipe is a fairly common problem that appears after dismantling the GBC. To understand how to get rid of this malfunction, you need to decide on the reasons why white smoke can go from the muffler.

• If the muffler leaves thick white smoke after the engine warming up, and smoke has large densityWhat is evidenced by a huge cloud, this indicates significant faults. In practice, white smoke occurs when antifreeze falls into the motor. Cooling consumables Enters the engine when the seals are wearing, designed to prevent antifreeze from entering the cylinder. It can also talk about worn out.
• Cracks on the GBC are also the cause of the appearance of thick smoke from the exhaust pipe. Such repair work It is better to trust professionals, because it is possible to remove cracks only with welding. If the crack is big, then to get rid of smoke, you will have to fully change the head of the block.
• If you are the owner of an old vehicle, which is equipped with a valve with a vacuum hose for a motor, then the appearance of smoke can be due to leakage transmission Oil. AND transmission fluid Drives directly through this valve. This consumable material quickly pollutes the spark plugs, as a result of which it will cause the failure of one of the cylinders. To get rid of smoke, check the valve and replace it.

After replacing the gasket of the GBC, the machine does not start? List of possible causes

It often happens that. As a rule, the reason is in the wrong assembly. Unfortunately, many novice mechanics allow assembly errors. For the most part, the shortcomings in the repair of all the same. At the same time, some of the errors can lead to very serious consequences. Up to overhaul Total engine. Therefore, it is important to immediately make an assembly correctly. It will save you from many problems in the future.

Explore all the features of the installation of the GBC, and also read proper setting Engine. It is advisable to consult with experienced mechanics, they can suggest how to do certain works.

After replacing the gasket of the GBC, the machine does not start? It often happens because of the bold marks of the gas distribution mechanism. Some mechanics inattentively laughing the position of the pulleys when dismantling the head. Also often very inactively set timing. But even a small displacement of labels leads to a failure in the engine. In this case, compression tact occurs in one cylinder, and the rank of sparks in the other.

To avoid such a problem before disassembling the engine, be sure to output the labels so that they completely coincide. When installing the head back and assembling the timing of timing, you must check the complete match of the labels. On some models there are additional marks on the flywheel. It is impossible to forget too.

If you are mistaken with setting tags, then after their correct placement, you can expect another trouble, often accompanying the phase phase failure. We are talking about the curved valves. Therefore, if after returning the timing tags of a normal position, the car still refuses to start, you have to remove the head and check the status of the valves. Often they turn out to be swung. The fact is that when the phases shifts the risk of a piston meeting with the valve increases many times. Scrolling the engine starter, literally at a time you can soak all the valves.

If you have such a trouble happened, you will have to completely change the valve. At the same time, do not forget to turn them. After tickling, be sure to rinse the items and dry them. If the valve remains a wipe paste, it can lead to increased wear of the pistons and damage to the cylinder.

Problem with padding

If your car, after replacing the gasket, first started, but after a short work, the ranks and refused to start. Check the condition of the oil. If there is a white foam in it, it means exhibit or damage to the gasket. It may happen because of the weak tightening of the bolts of the cylinder cylinder or incorrect sequence of this work. The operation of the engine in such a state is prohibited. Be sure to take action to eliminate the problem.

To do this, you will have to remove the head of the block. When inspecting the laying it turns out that it is damaged. It is necessary to remove it and carefully clean the surface of the block and the GBC. The remains of the old gasket can also lead to a similar problem. When assembling, pay attention proper tightening bolts. It follows from the middle to the edges. Thus, the deformation of the GBC does not occur, and the process passes as efficiently as possible. The tight should be made with a certain point of force, it is best to use a dynamometer key. After assembly, do not forget to change the engine oil ,. And also need to replace antifreeze.

Ignition

On carburetor engines, the problem may be. When removing I. installation GBC. Such problems may even have experienced masters. Of all the problems with the engine factory after changing the gasket under the head of the cylinder block, this is easily solved. At the same time, consider which ignition system is used in your car.

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 a sealing of the engine cooling system (channels), the seal of the oil system of the motor (channels), and the seal 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 save on repair GBC or 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 fluid in the radiator there are stains of oil, then most likely the engine oil falls into the cooling system due to poor 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 reverse order. Especially for this moment you sketched the scheme. Delay bolts GBC. It is necessary to strictly with the drawing for this block, and at the same time it is necessary to follow all the parameters of the protrapet that is indicated by the manufacturer. 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, there may be no rejection and docking technologies, but in general, all actions are needed to be almost the same and similar (universal 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. Disassembling the head of the cylinder block cannot be started when attached attached units. 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!

Many call the engine with the heart of the car. In fact, it is. It is the motor drives a car. DVS - the most expensive unit in any car. This node consists of several components. In addition to hinged equipment, there is a block and head of cylinders. Each item has its own device and purpose. And today we will look at what CHC is in the car, and why the car may not start after replacing its gasket.

Characteristic

GBC is decrypted as cylinders. This is one of the most responsible knots in the car engine.

It is the GBC that is responsible for controlling the combustion of fuel, as well as for the removal of exhaust gases.

Material

Over the years, the head has been made from the same material as the block. It was cast iron. But since the 80s, Aluminum came to change the cast iron. It is from this material that 90% of all heads are manufactured.

But not all motors there is the possibility of using aluminum cylinder heads. The reason is the high temperature mode, in which the deformation and thermal shrinkage of the metal is possible. Therefore, cast-iron GBC is still used on such engines.

Device

Constructively, this node combines:

• Carter. This is the block head housing.
• Spark plug. For them in the head there are special threaded holes. Candles participate in ignition fuel mixes. On the diesel engines These are missing.
• Nozzle. Designed to supply fuel under pressure.
• Gas distribution mechanism. It consists of pulleys, (maybe several) and valves. The latter are divided into two types. So, there are intake and exhaust valve GBC. What is in the valve car? These elements are responsible for the timely injection of fuel and gases from the chamber, which are formed after the ignition of the mixture.
• Camera combustion. For each cylinder is its own. Its volume can be different, depending on the CBC configuration.

Between the head of the head (what is a cylinder head in the car, we have already found out) and the block of asbestos necessarily places the unit. Also in the head design there are non-removable parts. They are installed by the method of hot pressing in Carter GBC. What is it in the car? Full parts are valve saddles. Installed in a place where the block head is in contact with the intake or exhaust valve. The saddles are a massive steel ring with a conical profile. When they are malfunction, it is necessary to use special to replace. At home this operation is not performed.

As installed

The CCC is superimposed on the engine cylinder block from above. It is fastened with long bolts, or a carving stud. Since the landing area is large, when installing the bolt delaying. This will eliminate the deformation of the design and possible tributes, as well as a breakthrough of gases.

Note that in the row power units, the GBC covers the entire block. And on V-shaped engines for each row provided its head. But regardless of the type of layout of the cylinder block, a reinforced gasket is installed between the head and it. What is the gasket of the GBC in the car? This is a sealing element. The gasket is made of solid refractory material, which prevents the mixing of the coolant with the spent gases and oil. This detail is installed on all engines. internal combustion. Exception is only some sports internal. Here the head is grinning as smoothly and smoothly that its contours completely coincide with the cylinder block.

After replacing the GBC gasket, the machine does not start

Sometimes it happens that this element loses hermeticity. Simple words, the gasket burst. In this case, with the engine factory, the car smokes. After replacing the gasket, the GBC everything should return to the ravois. But if it improperly set the tags, then the car may not start at all. But when replacing or repairing the head of the block, you will definitely encounter such a mechanism as timing. It is driven by a belt or chain. Torque comes from crankshaft Engine. By producing a disassembly of the belt or chain, it is necessary to mark the location of the pulleys. When installing the drive, it is important to comply with the accuracy of setting tags. The slightest deviation can cause the machine after replacing the cylinder machine.

A more serious outcome - the failure of the phases of gas distribution. This is fraught bent valves and damaged pistons. Scrolling the starter only once, you can fly to a large amount of repair.

How to solve the problem

Consider the marking process on the example of the VAZ-2109 car. For work, we need a good flashlight, a slotted screwdriver, as well as keys on 17 and 19. After installation tensioner roller timing belt timing need to be checked pulley distribution Vala.. It is necessary to twist it until the label coincides with the bar, which is located on the KVS block. After that, we leave the camshaft alone.

Go to the crankshaft. There are also own labels here. At this shaft you need to hire a bolt. Tags are so faster. You should scroll the shaft until they are in a vertical position. Next, take out the rubber plug in the clutch crankcase. After that, we will open access to the flywheel. Why do we need it? Here, too, there is a label, which ideally must coincide with the slot of the plank, which is attached to the cylinder block. If these designations coincide, it means that we correctly set the position of the timing elements. After that, you can safely install the belt. At first it is put on the crankshaft pulley, and then the camshaft.

Finally

So, we found out what CHC is in the car. Block head is a very responsible node in any engine. With the slightest malfunctions, problems arise with the work of everything power aggregate. If the gasket is broken in the engine, you should not slow with the replacement. Otherwise, the gases will penetrate into the cooling system and mix with Tosol. And the latter will fall into the combustion chamber, because of what the engine work from the exhaust will go thick white smoke.
