Replacing the cylinder head of a VAZ 2110 8 valve injector

It is important for VAZ 2110 owners to remember that the cylinder head gasket is a disposable part, therefore it must be replaced whenever this unit is disassembled.

In our material today we will talk about when and how to change the cylinder head gasket. These recommendations are equally suitable for owners of the “ten”, under the hood of which engines with 8 and 16 valves are installed.

Element appearance

When is replacement required?

The primary issue that concerns car owners is the frequency of replacing the element. Even if the unit is not disassembled, the seal has a certain service life.

In general, the lifespan of a gasket directly depends on the quality of the material used in its manufacture. Also, the frequency of replacement is affected by the intensity of use of the vehicle.

As we have already noted, replacement should be performed when disassembling the BC head, or when primary signs of wear appear.

What is this?

What exactly is this gasket?

This is a rubber element that has a certain elasticity. With use and wear, elasticity is lost. This reduces the quality and efficiency of performing the main task of the element - sealing the connection between the cylinder head and the cylinder block.

In order for the engine to work properly and without problems, the gasket must be installed efficiently and reliably. Ignoring its wear will lead to a serious reduction in engine life.

Signs of wear

If your old gasket is worn out, it won't be difficult to determine. There are several characteristic signs of loss of elasticity of a rubber element:

White steam starts coming out of the exhaust;
Traces of coolant or engine oil leakage appear at the cylinder head joints;
Traces of oil appear in the coolant;
An impressive amount of lubricant accumulates in the pan;
Foam forms around the filler cap.

To check for the presence of steam in the exhaust gas, you need to remove the cap from the expansion tank with coolant and put the bag on the neck. If after a short period of operation of the power unit the bag inflates quickly, the gasket is worn out and therefore needs to be replaced.

When should you change?

The need to replace the cylinder head gasket on a carburetor or injection car arises when, during use and due to natural wear, the seal loses its elasticity. This leads to a decrease in the quality and efficiency of fulfilling the main purpose - reliable sealing of the cylinder head connection with the cylinder block itself.

It is necessary to replace the cylinder head gasket on a VAZ 2110 in the following cases:

If oil drips appear at the junction of the head and the block. There may also be a refrigerant leak in this area.
The presence of light-colored foreign impurities or foam in the motor fluid. This can be detected by removing the dipstick from the inspection hole. The formation of a foam emulsion and the appearance of impurities occurs as a result of mixing engine and coolant fluids.
Change in color of exhaust gases. A more saturated white-blue gas comes out of the car's muffler. This indicates that water has entered the combustion chamber of the cylinder block.
The appearance of oil stains in the expansion tank with antifreeze.
Increase in power unit temperature. As a result of exhaust gases entering the cooling system, the antifreeze heats up much faster. This leads to an increase in engine temperature.

User Sergei Tsapyuk showed in his video the consequences of a burnt-out head gasket in a VAZ car.

What is a cylinder head

The cylinder head is one of the main components of the machine. What role does she play? Its purpose is to control fuel combustion processes in the engine, as well as to remove exhaust gases.

VAZ 2110 car with internal combustion engine 16 valves

As the name may suggest, the cylinder head is the engine cover. This element is secured to the block with large pins. Tightening the pins is one of the main procedures that determines the performance of the motor, but we will not consider this process.

How to change it yourself?

Replacing the cylinder head gasket on a VAZ 2110 with an injector or carburetor engine requires certain knowledge and skills.

To change the head mechanism on an 8 or 16 valve engine, you must carefully prepare for this task.

Tools and materials

If you change the cylinder head gasket yourself, you will need:

star key;
a set of ratchet wrenches with socket heads;
Phillips and flat head screwdrivers;
torque wrench for tightening cylinder head bolts;
spark plug key.

Channel Sdelaj Sam! Pljus interesting! published a video that will help you understand how to correctly determine the burnout of the cylinder head gasket between the cylinders of the power unit.

Step-by-step instruction

A detailed guide on how to remove and change the cylinder head gasket on a VAZ 2110 is given below:

Drive the car into a garage with a pit or onto an overpass; if possible, it is better to use a lift, since some of the work will be done under the bottom of the car.
Open the hood and loosen the bolt securing the battery terminal, disconnect it. This is necessary in order to prevent voltage surges during repairs.
Then disconnect the intake line from the exhaust pipe.
If the car is equipped with a carburetor engine, then the carburetor itself must be removed.
Disconnect the lead cables from the spark plugs. A wire with a connector is connected to the power unit temperature controller; it also needs to be removed. After this, disconnect the plug from the pressure and engine fluid level controller.
Loosen the fastening and disconnect the vacuum booster tube that is fixed to the intake manifold.
Disconnect the connectors and disconnect the ignition distributor controller.
Remove the gasoline pump with all its components. Loosen the clamps and disconnect the pipes connected to the pumping device. Some fuel may come out of it, so use a rag when dismantling it.
Using a wrench, loosen the screw securing the timing belt tension roller. This will allow you to remove the wheel along with the belt.
Next, secure the camshaft toothed disk to prevent it from turning during further repair work.
Unscrew the fixing screw and remove the pulley from its seat. To perform this task, you need to use two screwdrivers at the same time.
Next, locate the nuts securing the rear timing cover. You need to unscrew them and remove the cover. Using a Phillips head screwdriver, loosen the clamps to disconnect the pipes connected to the cylinder head exhaust pipe.
Using a hex wrench, remove the cylinder head mounting screws, there are ten in total. The bolts are removed along with the washers. Assess the condition of the latter. If washers or bolts are damaged, they must be replaced with new ones. The screws themselves are reusable parts, but they often wear out, leading to the need for replacement. You can tell how worn the bolts are by their length. If it is about 13.55 cm, then purchase new clamps in advance.
Then the cylinder head with the failed seal is dismantled.
During further installation of the GB, new screws must be lubricated with engine fluid. This will ensure simple and reliable fixation of the parts. In addition, lubrication will prevent accelerated wear of the bolts.
The contact surfaces of the head and the block must be thoroughly cleaned of wear and contaminants. These elements usually show signs of an outdated gasket. Thoroughly clean and dry the surfaces before further installation of the service seal.
Perform a visual inspection of the mounting screw holes. Often when repairs are carried out, they contain residues of the sealing element, engine fluid or antifreeze. Any dirt in the holes must be removed.
A new seal is being installed, which must first be cleaned and dried. During installation, make sure that the hole used for the passage of engine fluid is located between the fourth and third cylinders. Also, when installing the gasket, make sure that the valve elements of cylinder 1 are closed.
When the installation procedure is completed, you need to correctly tighten the cylinder head bolts, taking into account the sequence and torque. First, the two middle bolts are tightened - the bottom and the top, and then all the rest. On the first tightening circle, the torque should be 20 Nm, this indicator is controlled using a torque wrench. On the second lap the torque should be about 69.4-85.7 Nm. On the third circle, all the bolts are rotated 90 degrees in the prescribed order, and they are turned by the same amount on the fourth circle.
Further assembly is done in reverse order. When performing the task, it is not allowed to rotate the crankshaft and camshaft until you install the timing belt. The camshaft pulley is mounted in such a way that the protruding part of the hub is directed towards the car engine. When the repair procedure is completed, check the correct assembly and make sure there are no gaps on the valves. Also adjust the timing belt tension.

Stages of repair on 8 and 16 valve cars

Eliminating engine fluid leaks

Sorry, there are no surveys available at this time.
Leaking motor fluid from an internal combustion engine (8 or 16 valves) is an important symptom in which the cylinder head requires repair. Typically, fluid leaks from under the plug. It is located directly on the cylinder head at the rear of the engine. Leakage is usually caused by worn o-rings.

In order to replace the plug, you need to unscrew three bolts from the studs.
Having done this, you can remove the sealing rubber from the installation site.
It is better not to use domestically produced sealing gaskets, since their quality leaves much to be desired. In order to protect yourself from having to replace the ring again, it is better to use a sealant. For greater convenience, the sealant can be filled into a medical syringe.
Squeeze some sealant into the place where the plug will be installed. Wait five minutes before installing the new gasket in place and then installing the plug.

Replacing the unit

If this happens and you have to carry out not a repair, but a replacement of the cylinder head 2110 8 valves, and you do not have the skills to carry out such repair work, then our instructions will be useful to you:

Open the hood of the car and disconnect the negative terminal of the battery.
Place a container under the bottom of the car to collect used consumables. Locate the refrigerant drain plug and unscrew it. You need to wait a while until the antifreeze is completely drained, usually this takes no more than 15-20 minutes.
After this, disconnect the throttle cable and the intake pipe, as well as the wires located on the left side of the cylinder head of the 8-valve motor. In addition, you will also need to remove the connectors of the antifreeze temperature and engine fluid pressure control sensors. Don't forget to disconnect the cooling system pipes.
Next, in order to remove the block head, you should dismantle the receiver with the throttle assembly. In addition, you will need to dismantle such mechanisms and components as the intake manifold, a device for accumulating gasoline with injectors and all pipes, and the cylinder head cover.
Then, using a wrench, remove the bolt of the rear support bracket directly from the motor. You should also unscrew the toothed discs of the timing pulleys, and then the rear cover of the timing belt.
To remove the cylinder head, it is not necessary to remove the intake and exhaust manifolds. To remove the head, use a 10-point hex key: unscrew all the bolts that secure the top of the engine. The bolts must be removed along with the washers. After unscrewing the bolts, remove the cylinder head along with the head gasket.
Please note that the gasket is disposable, so it must be replaced every time the head is removed. Install a new gasket. After this, take the working cover of the block and install it, lubricating the end part with sealant. All assembly steps must be carried out in reverse order.

The request returned an empty result.

Consequences of untimely replacement

If the cylinder head gasket on the “Ten” is damaged or worn out, this will lead to the following malfunctions:

The engine fluid will begin to get into the antifreeze, and the coolant, accordingly, into the oil. This problem will cause the engine to overheat and the coolant to boil.
Steam will come out of the exhaust pipe, and the power of the power unit will be reduced to a minimum.
The engine may stall at idle and when driving uphill, and failures may occur when you press the gas pedal.
The coolant that gets into the lubrication system will make it difficult for the oil to work due to the fact that when mixed, the substances will lose their original characteristics.

As a result, regular use of a car with a worn gasket will reduce the service life of the car’s engine.

Video “Visual aid to replacing the cylinder head gasket”

User Vyacheslav Kravchenko suggests familiarizing yourself with the process of replacing the cylinder head gasket using the example of a sixteen-valve “Ten”.

Many owners prefer to repair their cars themselves, so it will be useful for them to know how to replace the cylinder head gasket on a VAZ 2110 (2112) 8 and 16 valves. This part plays an important role in the overall design of the engine. It is possible to perform such an operation yourself, but you will need to use a special torque wrench to tighten the bolts securing the head to the cylinder block. It can be easily found in most garage cooperatives.

Replacing the cylinder head gasket on a VAZ 2110 (2112) 8 and 16 valves

performed each time the head is removed from the cylinder block. This is provided for in the conditions of maintenance, operation and repair of this vehicle. The replacement procedure itself is important, but approximately the same, with rare exceptions, for all car models. Therefore, we believe that the article will be useful for many car owners.

What is she?

This part of internal combustion engines serves as a seal to the place where the cylinder head is connected to the cylinder block. The engine has another gasket that seals the valve cover with the cylinder head. These parts cannot be confused with each other; these are completely different products, their design, purpose and application are different.

This part seals three separate but interconnected engine systems at once. These are lubrication, cooling and gas distribution systems. It is because of this that very high requirements are applied to it. During the compression of the fuel mixture, high pressure is created in the combustion chamber, therefore, after each removal of the cylinder head, the gasket must be replaced.

If it is reused, it may burn out, causing the engine oil to mix with the coolant. This means that you will also have to change the engine oil with filter and antifreeze in the cooling system. Several types of such products are produced:

Gaskets made on a non-asbestos basis
are characterized as products that are easily restored and have minimal shrinkage;
Products made from asbestos
. Their high heat resistance, elasticity and elasticity are noted. They are recommended for use as repair kits;
Metal gaskets
. Today they are considered products that have high efficiency and quality, allowing the created pressure to be evenly distributed over the entire sealed surface.

Reason for replacing it

There can be many reasons for this, both for used cars and for new cars. In most cases, it is impossible to predict the timing of its replacement. There are certain signs by which one can judge the need for such an operation, but this often occurs suddenly.

Let's look at a few of the most common signs:

Noticed the appearance of drops of engine oil or coolant at the sealing area of the head and block;
The presence of whitish exhaust from the exhaust pipe is evidence of the penetration of coolant due to burnout of the gasket;
When checking the oil level on the dipstick, it was noticed that this is a sign of coolant entering the lubrication system;
The presence of oil stains in the coolant, which can be seen in the expansion tank or radiator;
Bubbling of the coolant is evidence of exhaust gases breaking through the burnt gasket into the engine cooling system.

Signs of failure of the cylinder head gasket of a VAZ 2110

There are no specific warranty periods for the use of a cylinder head gasket. Its durability is influenced by such factors as: the degree of operation of the engine, its model, driving style and other reasons. However, there are several symptoms by which you can determine that the gasket has failed:

at the junction of the block and the head there are leaks of engine oil or coolant ;
using an oil dipstick, foreign light impurities or foam-like emulsion , which occurs when antifreeze penetrates through the connection with the cylinder head;
the color of the exhaust changes to bluish-white, which indicates water entering the combustion chamber of the cylinder block;
presence of oil stains in the coolant reservoir;
The engine temperature rises due to the breakthrough of hot gases into the cooling system, which immediately heat the coolant.

Tips for replacing the cylinder head gasket

Removal and installation of the cylinder head gasket is carried out with the crankshaft set to TDC. It is also necessary to ensure that both valves of the 1st cylinder are closed.

After unscrewing the mounting bolts from the cylinder block, it is recommended to replace them with new ones, since with repeated use the bolts are pulled out, “metal fatigue” occurs and the bolt breaks under the influence of tension forces. Bolts need to be replaced if their length exceeds 135.5 mm.

It must be remembered that the cylinder head gasket must be changed after each removal of the engine head, even if this is not due to its unsuitability.

The bolts must be tightened in two stages with the sequence shown in photo 16. The first tightening stage is done with a torque of 20 N•m (2 kgf•m), the second with a torque of 69.4–85.7 N•m (7.1– 8.7 kgf•m), the second and third are the final adjustment of the bolts to 90°.

The procedure for replacing the cylinder head gasket on a VAZ 2110 on a 16-valve engine is generally similar to how to change the cylinder head gasket on an 8-valve engine, but has several nuances :

The receiver must be dismantled.
When removing timing belt pulleys, a mark is placed on two pulleys and two pulleys are removed.
The fuel rail is removed.
The order and tightening torques are carried out in accordance with the requirements for a 16-valve engine.
