Replacement of exhaust manifold gasket VAZ-2114 8 valves

Replacing the exhaust manifold and gasket on a VAZ 2114

The exhaust manifold is a unit that is responsible for ride quality, without which comfort is impossible. This is silence and the absence of exhaust smell under the hood, which can be drawn into the cabin through the hole in the cabin filter. Fixing a leak in the exhaust manifold of a VAZ 2114 is a necessary repair. Fortunately, it is not urgent; you can prepare in advance and choose a convenient moment.

Exhaust manifold for VAZ 2114

Causes of malfunctions

The key factor that causes 90% of exhaust manifold malfunctions on VAZ 2114 cars is high temperature and poor quality materials from which the parts are made. During operation, the steel repeatedly heats up and cools down, which leads to the appearance of cracks in the body. This is a common occurrence for VAZ cars older than 7-8 years.

Auto repair shops offer crack welding services using argon welding. However, for a number of reasons, this activity is useless for cars older than 7 years.

1) Just removing and installing the exhaust manifold will cost about 2.5 thousand rubles. Taking into account the work of the welder and other actions, the cost of repairs can be 4-5 thousand rubles. If you do the work yourself, buying a new part will cost less.

2) Welding, even argon welding, disrupts the structure of “tired” metal. A boiled part rarely lasts longer than a year, after which new holes appear. The older the car, the faster the problem returns, and the collector has to be removed again.

If the car is older than 8 years and there are problems with cracks in the manifold, it is better to remove the part and replace it with a new one.

Types of elements

Today two types of exhaust manifolds are produced:

• whole;
• tubular.

Solid parts have shorter channels, which are then combined into one chamber. Material: heat-resistant cast iron. The part has low gas removal efficiency. This is because the shorter manifold passages act as a barrier to gas pulses from the cylinder block.

Most parts are produced for mass use, and their quality often suffers. Such collectors do not have a vacuum zone. If they get too hot and then cool, the cast iron can crack. Then you will need to remove the VAZ 2114 exhaust manifold and replace it.

For sports and extreme use, a large number of exhaust manifolds are produced with various shapes and methods of connecting pipes. They are made of stainless steel. Car enthusiasts call these parts spiders. There are short spiders and long ones.

For example, on a 4-cylinder engine, the pipe system is represented by the formula 4-2-1. So, each cylinder has its own pipe. Then these pipes are connected into two, and then into one. This system is used in tuning. It allows you to increase the car's power and torque. The short 4-1 system is used in sports.

Signs of trouble

Exhaust manifold gasket

One of the main signs of a leak in the system is a “sporty” growling sound when the engine speed increases. This may be a symptom of various exhaust system problems. To check, it is better to take an assistant and go to a garage with a pit or to an overpass. Most often, you can determine by eye whether the problem lies in the muffler, resonator or exhaust.

Gasket wear may become apparent during planting. Open the hood and start the car - white or grayish smoke rising from the manifold during warm-up indicates a leak for this reason. VAZ car owners usually encounter this problem once every 3-4 years. When using low-quality spare parts and before. The solution may be to manufacture a custom-made steel gasket. It can last as long as the entire collector.

Prices and options

The Premier 2110 Lux is equipped with heated front seats and excellent velor upholstery. An armrest is mounted between the seats. Based on reviews from car owners, you can understand that the rear seat is a bit short and the backrest angle is small. But the developers claim that this will change soon. The interior of the car, especially if it is trimmed with leather, looks much better than other modifications.

In conclusion, I would like to say that the Premier turned out to be much better than the usual 2110. However, it is still far from being a representative car or a limousine. This is clear, because even the manufacturers themselves position this model as a car with improved passenger seating.

Tools and necessary parts

To remove the exhaust manifold on a VAZ 2114 in order to replace the gasket or entire part, you will need the following tool:

• open-end and ring wrenches for 8, 10, 13, 17;
• wrench with heads 17, 19;
• screwdrivers, pliers.

It is also a good idea to have tools such as a Dremel, nut saw or nut pick on hand. As a rule, the fasteners on the exhaust system parts stick tightly.

A few days before your planned repair, begin treating accessible nuts with WD-40 or another penetrating lubricant. Repeat the operation 2-3 times. This will make the task of removing the manifold a little easier .

The question often arises: is it worth using a sealant after removing and replacing the gasket? Experts believe that if you apply sealant to the gasket, it should only be high-quality silicone. A bad sealant can bring a lot of trouble to a VAZ 2114 engine: when it burns out, it turns into “pellets” that are pulled into the crankcase. And this is unnecessary contamination of the piston system.

Exhaust manifold removal procedure

Before removing the exhaust manifold yourself, think 7 times. Having this work done by a service center is not cheap, but the inaccessibility and difficulty of unscrewing some nuts can be a serious problem.

Unscrew the bolt securing the intake pipe

It is important to drain the coolant before removal, as antifreeze may enter the cylinders during the process. The sequence of actions for cars with an injector is as follows:

1. Disconnect the battery, release the throttle cable from the throttle valve.
2. Disconnect the fuel line pipes.
3. Disconnect the wires from the TPS and idle speed control.
4. Release the crankcase ventilation, vacuum, and brake booster hoses.
5. Remove the receiver, remove the injector block wires and remove the injector fuel rail.
6. Remove the bracket and thermal shield.
7. After this, you can disconnect the exhaust pipe, exhaust and intake manifolds from the manifold.

Dismantling

There is only one difficulty in this process - the inaccessibility of some fasteners. It is best to carry out this “operation” in a viewing hole or on a lift. Of course, this is not necessary, but it is much more convenient.

Work order:

1. First you need to remove the negative terminal from the battery or turn off the mains switch.
2. Next, it is recommended to drain all the antifreeze into a container prepared in advance.
3. Next, you need to disconnect the fuel pipes. If the coolant is not drained, at this stage it will go into the cylinders.
4. Now you have to find the throttle position and idle speed sensors, and then remove the wires from them.

5. We first remove the crankcase ventilation from the hoses, then the brake booster.
6. Remove the intake manifold (receiver) together with the throttle assembly.

7. Then remove the fuel rail (without disassembling) and the wires from the injector.

8. There's not much left. Now you need to remove the heat reflecting screen. The exhaust pipe of the muffler is unscrewed from the manifold.
9. We remove the exhaust manifold Kalina 8 valves from the BC head studs, to do this we unscrew the fastenings shown below in the figure

Replacing the exhaust manifold gasket on a VAZ-2114 with your own hands

Replacing the exhaust manifold gasket on a VAZ-2114 is a very complex procedure and requires certain knowledge and experience. So, not all experienced car enthusiasts are able to do this correctly. In addition to the fact that exhaust gases exit through the exhaust manifold, it is also responsible for the normal operation of the engine, since a lambda probe is installed on it.

Video about replacing the exhaust manifold gasket on a VAZ-2114

The video will tell you how to properly replace the exhaust manifold gasket, and also tell you about some of the subtleties and nuances of this process.

Required tool for replacement

Before you begin the process itself, you need to decide on the necessary tools. So, what will you need: a ratchet and sockets for 17, 19; screwdrivers with flat and Phillips tips; a set of keys and the gasket itself.

Now that everything is prepared, you can start working directly. In order for the manifold to be removed without any problems and rusted bolts not to create trouble, everything must be lubricated with WD-40 before performing the operation. It is advisable to do this several times. Before performing the operation, you need to think again, weigh everything and calculate your strength.
