Replacing the Exhaust Manifold Gasket VAZ 2109 Injector

Burnout of the gasket under the exhaust manifold is a rather unpleasant and common malfunction on the VAZ 2109.

A product that has become unusable will allow exhaust gases from a running engine to pass under the hood, and the characteristic chattering sound when the engine is under load also does not greatly contribute to a comfortable ride. Replacing the manifold gasket on a VAZ 2109 will help avoid such problems.

The collector gasket is made from a specially compressed asbestos mixture reinforced with steel thread; it can be purchased at any spare parts store. The price of the product, depending on the manufacturer, varies from 50 to 200 rubles. For a VAZ 2109, replacing the intake manifold gasket at a car service center will cost approximately 1,500 rubles and more, not counting the cost of the gasket itself.

Burnout of the exhaust manifold gasket is a rather unpleasant and common malfunction on a VAZ 2109 car. The manifold gasket consists of a specially compressed asbestos mixture reinforced with steel threads; you can buy it at any spare parts store.
The price of the product, depending on the manufacturer, varies from 50 to 200 rubles. For a VAZ 2109, replacing the intake manifold gasket at a car service center will cost about 1,500 rubles or more, not counting the cost of the gasket itself. Replacing the VAZ 2109 intake manifold gasket with your own hands is not very difficult and does not require technical knowledge or expensive tools: the necessary set of keys is usually in the trunk of every car enthusiast, but before replacing it, you should try tightening the fastening of the suction unit - if the gasket is not burnt, then the fastening is loose , which may cause exhaust gases to enter the hood. If tightening the holder does not help, the gasket is completely burnt out and must be replaced. Replacing the VAZ 2109 manifold gasket will require preliminary work to disassemble the air filter, remove the carburetor and the manifold itself.

All of the above work is carried out exclusively on a cold engine. On the injection engine of a VAZ 2109 car, to remove the air filter, it is enough to unscrew the four self-tapping screws of the filter element housing cover - for this, use a 10-mm wrench or a ratchet.

Preparation stages

To replace the manifold or its gasket, in any case you will have to dismantle the VK. But before you get to the element you are looking for, you will first need to go through some preparatory steps. Namely, tighten the fasteners, and then remove the air filter and carburetor if the first stage does not help.

Stage of work

Your actions

Often, loose manifold fastenings caused the entry of contaminants, which disrupted the performance of the exhaust system. If the tightening did not give any result, then the gasket is definitely burned out or the collector itself is damaged, which is less likely

Removing the air filter

Removing the carburetor is carried out in the following sequence:

All dismantling work must be carried out only on a cold engine. To make it easy to unscrew all fasteners, you can pre-treat them with WD40, several hours or even a day before the repair begins.

Preliminary work

Regardless of the purpose for which it was necessary to replace the intake manifold on a VAZ 2109, it will be necessary to perform the same steps.

Remove the air filter.
We remove the carburetor.

Let's look at everything in order, starting with how to remove the filter.

Removing the air filter

In general, this car part needs to be changed every few years, so this information will be useful to everyone who, in the days of the owls, became the proud owner of a VAZ 2109. The sequence of actions when replacing the filter is as follows:

fold three latches;
remove the filter cover - if possible, simply do it manually, otherwise take the key to 10;
lift the cover of the filter housing and remove the air filter; this is not difficult to do and does not require much effort;
Wipe the inside of the case with a clean, dry cloth.

To reassemble the filter later, all previous steps must be completed in reverse order. But even for novice drivers this procedure is unlikely to cause any particular difficulties. Now you need to think about how to remove the carburetor, because in order to replace the intake manifold of the VAZ 2109, this also needs to be done.

Removing the carburetor

To complete this procedure you need to accept:

two screwdrivers of different configurations;
head 8;
ratchet handle.

After removing the filter, all holes in the carburetor that previously connected it to the filter must be covered with a cloth - not wet or dirty. After this you need to do the following.

Unscrew the nuts on the filter housing and remove it completely.
Disconnect the cable from the economizer at forced idle.
We unscrew the clamps and disconnect the fuel hoses (there are only two of them).
Loosen the air cable bolts and remove this device. We remove the spring.
Loosen the nut on the bracket and disconnect the cables from the shock absorber.
Pry up the clip securing this cable and remove it completely.
Disconnect the plugs from the forced idle economizer sensor.
Disconnect the pipes from the carburetor heating system and from the vacuum pipe.
Remove the pipe related to the ventilation system.
Finally, we unscrew the nuts connecting the carburetor and the intake manifold (there are four in total, one on each side). Carefully remove the carburetor.

And now you can move on to the main part of this whole action and remove the manifold on the VAZ 2109.

Intake manifold gasket and the manifold itself - what is it?

Removing and installing the intake manifold The intake manifold of the VAZ 2109-2108 must be replaced in exceptional cases, but it must be removed more often, for example, when completely disassembling the engine or, for example, when replacing the gasket between two manifolds and the head.

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.

Removing and installing the fuel manifold and injectors

The Multiport Fuel Injection (MFI) system is a device controlled by the ECM. Measure the fraction of fuel under pressure in each cylinder.

The ECM provides control pulses to the fuel injector solenoid.

Fuel enters the top of the injector through the valve ball or needle and a recess in the guide plate as it exits the injector.

The guide plate has 6 holes to control the fuel flow, which form a conical stream of fuel towards the intake valve. The atomized fuel evaporates before entering the combustion chamber.

Conclusion Warning: The fuel system is under pressure. To reduce the risk of injury or fire, relieve fuel system pressure before disconnecting fuel lines.

1. Relieve fuel pressure.

2. Disconnect the “-” battery cable.

3. Remove the fuel injector harness connectors.

4. Remove the EGR valve.

5. Disconnect the power cord.

6. Remove the fuel manifold mounting bolts.

Before removing the fuel manifold, spray clean it according to the instructions provided.

Your lawyer

I didn't find any antifreeze in the cylinder block. :/ I suspect it leaked into the crankcase. I turned the pin with a wire cutter, locked it and turned it silently.

I assembled everything, started it, warmed it up - it doesn’t hold at idle and the timing belt is on fire, I understand. And so, running like an airplane (fly, alone, low) The feeling, after the perforated seal, is that I am deaf!

As it turns out, the main thing is not to lose faith!

I'm afraid there is antifreeze in the crankcase, does anyone know how to check this?

_Lelik_ July 05, 2009

Systemus July 06, 2009 Check the oil on the dipstick.

If it has whitish spots, there is antifreeze in the oil. When cold, there are no inclusions, the oil does not separate, and when starting the engine it runs for 5 minutes.

Small spots appear (like bubbles, possibly antifreeze), I’ll change the oil. O I didn't change the oil. Everything ingenious is simple, the walking speed was due to the disabled air sensor.

Everything became normal. The engine control sensor burned out and turned off.

And happiness came to me. The repairs were carried out according to the Murzilka ZR. What is not included in the gasket replacement description: 1.

When disassembling the suction pipe (pants), it is necessary to disconnect the lambda probe from the terminal. The nuts on the trouser stirrup were stuck: the stirrup had to be cut with a hacksaw, a new one costs 150 rubles.

2. Drain the antifreeze about 5 liters of antifreeze so that it does not cause excruciating pain for the flooded cylinder block.

3. Disconnect/connect the intake manifold

Removing the VAZ 2109 injector manifold. Removing, replacing, installing exhaust manifold gasket

Under the exhaust manifold of the VAZ 2109. For various reasons (uneven tightening of the nuts, aging), a gasket consisting of several layers is installed, it breaks and requires replacement.

The first sign of exhaustion is the appearance of a characteristic noise. Yes, you can drive as long as you don't worry about your ears.

But it is better to replace it in a timely manner, as a fire may occur in the engine compartment. The gasket is made of extruded asbestos reinforced with steel wire.

Recommended reading: Extension of the auction period upon application

The price for such a gasket, depending on the store and manufacturer, varies between 50-200 rubles. The cost of replacement at a car service is at least 1000 rubles.

And this does not take into account the cost of gaskets, nuts and other components that may require replacement. Therefore, doing the repairs yourself will be much more effective, saving a decent amount. Before replacing the manifold gasket, you need to understand how the process itself works.

You don't need special tools or the experience of a good level 80 specialist.

a standard set of tools found in every garage is sufficient. Briefly, the work process can be divided into several stages: removing the air filter; disassembling the air filter housing; removing the carburetor;

Dismantling of collectors

It's time to remove the intake and exhaust manifolds. Having disassembled them, you can understand whether the gasket can be replaced or whether the collectors themselves will need to be completely replaced.

The gasket is a consumable item, the purchase of which will literally cost you 50-250 rubles, depending on the manufacturer and region. Services for replacing the gasket at a gas station cost more than 1,500 rubles. Add to that the cost of a quality gasket and you're looking at big bucks. Such costs can be avoided if you do everything yourself.

Disassembled block

Intake manifold

Removing the air filter and carburetor will give you access to the intake manifold.

To disassemble it, you will need a certain set of tools:

Ratchet with 10mm head;
Collar;
Ratchet;
13 deep head;
Normal head 13;
Spanner 13.

When everything is ready, you can start working.

Unscrew a couple of mounting nuts to fold the cover under the carburetor.
Disconnect the hoses from the intake manifold.
Remove the six retaining nuts located on the intake manifold.
Remove the manifold itself from the studs. To do this, simply move the knot to the sides. It often sticks to the gasket, causing removal problems.
Inspect the condition of the unit. If damaged, the collector is replaced.
If the problem is only in the gasket, put the inlet aside for now and start removing the graduations.

An exhaust manifold

To dismantle the graduation you will need:

Ratchet;
Fixed key at 13;
Wrench 13;
Deep head 13.

All is ready? Then let's get started.

We unscrew the four nuts securing the front exhaust pipe from our exhaust manifold.
Remove the so-called pants from the heels and move them to the side. Now you can unscrew three more nuts securing the VK.
Carefully, without sudden movements or jolts, disconnects the graduation from the pins.
It is not uncommon for the manifold or its retaining nuts to stick to the seats when disassembling this unit. To prevent this from happening, pre-treat the assembly with a WD40 tool, let it work, after which there will be no problems with dismantling work.
If the pins break during removal, you will need to drill out the old piece, create new threads, and install a new pin.

Pad

Well, an inspection showed that a burnt gasket was to blame. Therefore, it will only need to be changed.

Pad

Alas, to get to a simple gasket, I had to remove the air filter, carburetor, exhaust, and intake manifolds. But we can’t do without it.

To replace an old worn gasket, you will need:

Remove the old gasket. Some difficulties may await here, since most likely the gasket was attached correctly and burned to the cylinder head;
Armed with a thin screwdriver, sharp knives, aerosol solvents;
Spray on surfaces first, then leave to work. It's best to take the time to simplify things;
When the product is working, begin to gradually remove the old gasket from the surface of the block;
Be sure to remove carbon deposits from the mating surface of the cylinder block. Here you will need not an aerosol, but full-fledged sandpaper. Do not use coarse-grain paper;
Install a new gasket on the exhaust and intake manifolds of your VAZ 2109;
Reassembling the assembly is done in reverse order. That is, first both manifolds are installed, then the carburetor and air filter are returned to their “homeland”, the fasteners are properly tightened and the result of the work done is checked in practice;
Of course, we should not forget about the coolant that is drained in the early stages. By the way, this is a very good reason to change it to a new one.

By installing a new gasket, it is up to you to ensure the long life of the new gasket. To do this, before installation, lubricate the gaskets on both sides with graphite grease. This way, you increase the product's resistance to the extreme temperatures it regularly encounters. Similarly, for the same purpose, lubricate the cylinder head studs with graphite grease.

Replacing the Exhaust Manifold Gasket VAZ 2109 Injector

Replacing the exhaust manifold and gaskets on a VAZ 2114 The exhaust manifold is a unit responsible for ride quality, without which comfort is impossible.

And you shouldn’t immediately make the mistake that there is a twist in the gasket. First try tightening the nuts. It is possible that they have weakened a little. But if it was not possible to eliminate the passage of gases, it is necessary to begin repairs.

This is silence and the absence of the smell of exhaust gases under the hood, which can be sucked into the cabin through the opening of the cabin filter. Eliminating leaks in the exhaust manifold of a VAZ 2114 is a necessary repair. Fortunately, this is not urgent; you can prepare in advance and choose a convenient time. Exhaust manifold on a VAZ 2114 The key factor that causes 90% of exhaust manifold malfunctions on VAZ 2114 cars is high temperature and poor quality materials from which the components 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 various reasons, this activity is useless for a car older than 7 years.

1) Simple removal and installation of the exhaust manifold will cost approximately 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.

Causes of malfunctions

The gasket is placed between the exhaust manifold and the cylinder head. The stamped asbestos gasket is resistant to high temperatures, can be compressed (creating the necessary impermeability) and has increased strength. To enhance the latter quality, the exhaust manifold gaskets are additionally reinforced with steel.

IMPORTANT! The main task of the gasket is to prevent exhaust gases from penetrating under the hood, where they can cause ignition of parts/assemblies of the engine compartment. The gasket is recognized as the most vulnerable point of the exhaust manifold, which operates under extreme loads in both temperature and pressure. It is not surprising that gaskets have to be changed not only on cars with a significant mileage, but also on almost new cars

The gasket is recognized as the most vulnerable point of the exhaust manifold, which operates under extreme loads in both temperature and pressure. It is not surprising that gaskets have to be changed not only on cars with significant mileage, but also on almost new cars.

Gaskets need to be rotated for several reasons:

poor factory quality;
engine overheating due to intensive use;
engine repair (a used gasket loses its properties when dismantled).

Replacing the exhaust manifold of a VAZ 21099 with a spider video with an injector

And don’t forget to add the coolant that was drained when removing the carburetor!

To ensure that the new gasket lasts as long as possible before installation, it is recommended to coat the product with a layer of graphite lubricant on both sides - this will extend the life of the material and increase the tightness, and will also help avoid burns. It is also recommended to coat the cylinder head studs with a layer of graphite lubricant. Good luck! VAZ 2109 pants are replaced very rarely, since it is an all-metal assembly.

The gasket is changed more often, since the impact of hot exhaust gases on it is very strong. But to be honest, during the life of the car for 10-15 years, there is a possibility that the metal pipe of the VAZ 2109 trousers will also burn out and the manifold gets into the front pipe.

In addition, its metal is relatively thin, and as a result, cracks form on its surface, and the pants can simply fall off the rod. An example of such a breakdown is clearly visible in the photo; their service life was exactly 15 years. It is convenient to carry out all work in a pit or overpass.

If, of course, such working conditions do not exist, then in the field it is possible. To do this, simply remove the air filter housing. Replacing or disassembling the VAZ-2114 exhaust manifold is necessary in the following cases: Mechanical damage to the manifold.

Deformation and loss of tightness at the junction with the cylinder head. Burnout of the gasket between the head and the manifold.

Some information about the exhaust manifold

This device, which is part of the vehicle's exhaust system, is necessary to remove exhaust gases from the cylinders in a common pipe. In addition, the manifold is designed to improve the process of filling the combustion chambers and their high-quality airflow. The exhaust manifold operates at high pressures and temperatures. Firmly mount it to the cylinder head () and connect it to the exhaust pipe or a suitable catalytic converter.

The gasket we are interested in is located between the cylinder head and the manifold. Its main task is to prevent exhaust gases from entering the engine compartment, which can cause a fire in components and parts of the engine compartment.

The exhaust manifold construction (stainless steel or high temperature cast iron) is extremely durable. Repair of this unit in a modern car is extremely rare. Experts say that the collector can fail only when cracks form on its surface caused by moisture entering the hot metal.

But manifold seals, unfortunately, are the weak link of this reliable mechanism, which is accustomed to working in very difficult conditions. These are the seals that often disappoint the motorist. They need to be changed periodically both on cars with high mileage and on engines that are still very “young”. In the second situation, premature wear of the seals can be caused by the following reasons:

low quality sealant;
intensive use of the vehicle in difficult road conditions (poor roads, high mileage in a short time, etc.).

Self-replacement of the exhaust and intake manifold gasket on a VAZ 2109

// Burnout of the exhaust manifold gasket is a rather unpleasant and common malfunction on a VAZ 2109 car.

A product that has become unusable will allow exhaust gases from a running engine to pass under the hood, and even the characteristic chirping sound when the engine is loaded does not greatly contribute to a comfortable trip. Replacing the manifold gasket on a VAZ 2109 will help to avoid such problems.

The manifold gasket is made from a specially compressed asbestos mixture reinforced with steel threads, which can be purchased at any parts store. The price of the product, depending on the manufacturer, varies from 50 to 200 rubles. For a VAZ 2109, replacing the intake manifold gasket at a car service center will cost approximately 1,500 rubles or more, not counting the cost of the gasket itself.

Replacing the VAZ 2109 intake manifold gasket with your own hands is not difficult and does not require special knowledge or expensive tools - the necessary set of keys is usually in the trunk of every motorist. But before replacing, you should try to tighten the fastening of the intake unit - if the gasket is not burnt out, it is the loose fastening that could cause exhaust gases to get under the hood. If tightening the holder does not help, the gasket is completely burnt out and must be replaced.

Recommended indications: Bone marrow collected in Penza

Replacing the VAZ 2109 manifold gasket will require preliminary work to disassemble the air filter, remove the carburetor and the manifold itself.

Basic aspects of manifold tuning

The basis of tuning is polishing inside and out. Thanks to this, you can achieve a neat and attractive appearance. This action improves performance. When the walls in the collector are smooth, gases move through it in one direction without resistance. Faster purging can improve engine cooling.

On VAZ 2109 cars, by polishing the spider, its internal diameter can be increased. Exhaust gas flow increases, as does engine efficiency. Sequence of work:

Before removing the manifold on a VAZ 2109, you need to dismantle all attachments and disconnect the cylinder head.
Disassemble the cylinder head, dry out the valves, remove the rocker arms and springs.
Using the head at “6”, pull out the guides.
Remove the inlet and outlet devices.
Eliminate defects (if any) on the cylinder head, exhaust and intake manifold. A spider that is deformed or has obvious damage cannot be installed.
Mill the block head by 1 mm.
Wash the cylinder head until it shines. If the gasket is stuck to the block or cylinder head, get rid of its remains without using metal objects.
After lubricating the valve guides, mount them in place. To work, use an “11” head and a hammer.
Check the condition of the valves. If there are deformed ones, change them.
Assemble the head, install rocker arms, caps, valves.
Reinstall the intake and exhaust manifolds. The manifold gasket must be replaced; an old one cannot be installed.
Install the cylinder head onto the block using a new gasket and bolts.

The general algorithm for carrying out the work is not very complicated, the main thing is accuracy and precision. Do not trust cylinder head milling to dubious workshops. Otherwise you will have to buy a new one.

Collegium of Advocates

The exhaust manifold on the VAZ 2109-2108 must be removed more often in connection with replacing the gasket, because if it burns out, then at that moment it begins to cut and the exhaust gases will go under the hood, and the sound of the operation will be quite strong. In general, this problem will not lead to anything good.

To remove the exhaust manifold, you must first follow these steps: After this, we will need very few tools, namely: a wrench or a 13-deep socket wrench for a 13-deep ratchet extension So, first you need to unscrew the 4 nuts that secure the exhaust manifold manifold to the pants (suction pipe), which are shown in the photo below: And move the pants a little to the side, pulling them out of the pins.

Then it is necessary to unscrew the remaining three nuts securing the manifold, since the remaining 6 were unscrewed when removing the intake. And now the exhaust manifold of the VAZ 2109-2108 can be easily removed from the studs by pulling it back: if a gasket is attached to the cylinder head, it can be carefully peeled off with a knife blade or a thin screwdriver, and then completely removed from its seat: After it turns out that this is a rather unpleasant picture: you can remove traces of the old gasket on the surface of the cylinder head using a special spray, applying it to the entire area and waiting for at least 15 minutes: Residual traces can be removed with a thin blade, and you can finally return it to perfect condition by treating the entire surface with the finest sandpaper, the so-called zero.

Full list and action plan »

April 24, 2022 Signs of a blown exhaust manifold gasket. Complete List and Action Plan In this article, we will discuss the symptoms of a blown exhaust manifold gasket. For an exhaust device, the gasket is one of the main parts on which the entire correctness and accuracy of the exhaust system will depend.

If the manifold gasket is replaced prematurely, the safe operating conditions of the vehicle are significantly reduced. In general, a manifold is a device designed to remove exhaust gases from a car engine. The second function of the collector is to improve the filling of the working chambers and enhance the airflow of the working space.

All operations of the exhaust device are performed at elevated temperatures and high gas pressures.

This element is mounted directly on the cylinder head (cylinder head), and the other side is in contact with the exhaust pipe or converter. The most important job of an exhaust manifold gasket is to keep exhaust gases from entering the valve space. These gases, in turn, can ignite parts or components of the power unit.

Weak link in the system and signs of its failure Symptoms of a burnt exhaust manifold gasket can be distinguished as follows: exhaust gases begin to flow into the vehicle or emit an odor; the car engine begins to start poorly; Strange noises appear in the engine compartment.

If these ailments are detected, you should begin inspecting the exhaust system.

conclusions

Replacing the exhaust manifold gasket on a VAZ-2114 engine is a rather complicated and difficult task, which can become a serious challenge for many novice car enthusiasts. But if you follow the instructions, everything will work out. Well, if not, then the direct route is to a car service center. Particular attention should be paid to the quality of the product so that you do not have to change the part after several thousand kilometers.

Symptoms:

sucks air into the engine cylinders, intake noise is heard from under the hood; exhaust gases burst under the hood.

Possible reason:

the intake manifold (manifold) gaskets are worn out; The exhaust manifold gasket is worn.

Tools:

one set of wrenches, one set of sockets, one set of screwdrivers.

1. Place the car on an inspection hole or overpass.

2. Drain the engine cooling system.

3. Disconnect the exhaust manifold and front exhaust pipe.

4. Remove the air filter housing from the vehicle.

5. Disconnect the pneumatic drive rod from the carburetor, then disconnect the throttle valve drive cross rod from it.

6. Remove the battery. This is optional, but recommended to improve access to other parts and fasteners.

7. Using a 13-inch socket wrench, remove the lower nut securing the air intake.

8. Using a 13-inch socket wrench, unscrew the top nut securing the air intake, then remove it from the vehicle.

9. Remove the top nut holding the starter heat shield in place.

10. Using a 13-inch socket wrench, unscrew the lug lock nut, then remove it.

11. Using a 13-inch socket wrench, remove the nut securing the ground wire, then remove the ground wire from the stud (the timing chain tensioner has been removed for clarity).

12. Using a 10 mm wrench, remove the two nuts securing the coolant inlet hose to the coolant pump, then disconnect the hose. When reinstalling, replace this gasket with a new one.

13. Using a 13-inch socket wrench with an extension, remove the seven nuts that secure the intake manifold to the exhaust manifold. Please note that under the intake and exhaust manifold hinge nuts, washers are installed that are slightly thicker than the others (the attached photo shows the mounting locations for the intake manifold and exhaust manifold).

14. Disconnect the intake manifold from the engine head by removing the first stud from the second stud. Then move the manifold to the side.

15. Remove the exhaust manifold from the cylinder head studs.

A good driver must maintain his car efficiently and in a timely manner, but always be prepared for the unexpected. After all, it is very difficult to check the condition of all the components, parts and seals of the machine, which at any moment can fail and stop performing their functions. Therefore, one of the most unpleasant “surprises” for motorists is damage to the exhaust manifold gasket.

Changing the resonator

It is also advisable to replace the resonator on a VAZ 2110. This is done after changing the muffler.

New resonator for VAZ 2110

The work of replacing the resonator is performed in the following sequence:

The resonator is secured to the muffler with a crimp clamp with an O-ring.
It is attached to the neutralizer using a floating flange consisting of two bolts and a flare.
On the opposite side of the element there is a so-called fist.
Removing bolts is often quite difficult. So that you don't have to suffer, just cut them off with a grinder and buy new bolts. This is the simplest solution to the problem.
If you couldn’t get a grinder, use a liquid key. This is a popular product among motorists - WD40 or its analogues. Treat the bolt attachment points with this compound, wait a while, after which the bolts should come off.
After removing the bolts, remove the muffler clamp.
Remove the resonator from the suspension rubber bands. Check the condition of the rubber bands. If they are worn out, replace them with new ones.
Take a new resonator, secure them to rubber and connect them to the muffler so that the pipe leading to the muffler from the resonator is parallel to the ground.
If you notice wear, burrs, or traces of rust on the neutralizer fist, be sure to coat the connection with sealant. Moreover, it must be a high-temperature sealant.
Armed with new bolts and nuts, tighten the catalytic converter and resonator flanges.
The neutralizer is fixed to the resonator with two bolts using a flange connection. The fastening occurs to the states, but there is a receiving pipe, using a spring-loaded connection and two flares. The space between them contains a sealing ring made of graphite or metal asbestos.
