Do-it-yourself nissan example p12 muffler repair

In detail: do-it-yourself repair of a nissan example p12 muffler from a real master for the site my.housecope.com.

Well, I was touched by the well-known problem with the rotten muffler flange. The machine growled like a tractor, its ears were already blocked)) The flange was completely rotten and the middle part of the muffler just hung on the rear beam. There are 3 options: cook a new flange, buy a new middle part, or come up with something yourself. The pipe itself and the muffler are in good condition, without strong rust, not rotten. Somehow I didn't want to cook a new flange from the nine, the new middle part is a little expensive. Let's think for ourselves.
On the Internet, I found such a miracle the Jp Group clamp 1121400500 costs only 180r. on the existential.

It turns out companies such as Audi, Volkswagen, Renault, etc. They have long used such clamps instead of welding in their exhaust systems. Such clamps are of different diameters, so we take a vernier caliper and go to measure the pipe diameter, which is 45mm.
We order a clamp (you can, of course, look in stores, but I did not find it).
When the clamp came, I drove to a friend's garage with a pit, cut off the old flange, cleaned the seats with a wire brush, smeared Abro with red sealant just in case, and put on the clamp. Its length is 9 cm, just enough.

I found some kind of wiring that clung to the flange nut, hooked it separately on a regular clamp (you can see it in the photo).
But the old flange, which I cut down, you can see how rotten it is

On the very bank of the muffler, rusty metal also dangled, which spoiled the whole view and constantly annoyed my eyes, I decided to cut it

At the same time I changed my shoes to summer tires, here is a view from under the rear right wheel

I wound up, peace and quiet) Nothing siphon anywhere, the glushak hangs as it should, does not sag, I hope it will last for a long time. By the way, the clamp is made of aluminized steel (with the addition of aluminum), so it does not rust for a long time. On the existential side, there are a lot of analogues from such eminent companies as Bosal, etc., the choice is good and the prices are very different. I took a cheaper one, the quality pleased me, the metal is quite thick, the clamp is strong and reliable, in general, an excellent alternative to welding.

Good afternoon! I present to your attention a photo report of the repair of my muffler.

At the beginning of the year, it began to tinkle under the bottom. With a friend, they took off all the cans under the car, there is no effect, it rings and rings.

Once we got under the car again, Nuka says, go, turn it on D and turn it off. That's exactly what I did. He saw that there was a very large crack in the place where the muffler pipe connected to the can. When I gasped, he just pressed it and the ringing stopped.

took a semiautomatic device, scalded the place where the crack is

Now you go, nothing rings, no strumming, BEAUTY.

Well, now it's my turn to change the muffler and think about how to improve something more practical, but also so that you can change at any time and do it the way it was.
And so let's start with the fact that the resonator burned out, welded.
Climbing at auctions came across one interesting copy of the Nissan SPORT muffler, very effective and sporty, it is clear that this is not a sports car, I wanted to hear the sound of what kind of engine it is.

Name Silencer for NIssan Presage 1 piece used NISMO
Quantity 1
Order value JPY 17,000
The price suited me, delivery cost + 3.5tyr. rubles

Here is how the muffler was in the photo, in the same condition I received it, a mirror made of stainless steel.

At first I listened to the sound without a muffler at all, the difference was not very big, then I put it with a resonator. I also want to tell you that there is practically not any difference, there was a slightly bass sound when only the car was slowing down.

Then I decided to open the resonator and half-remove all the partitions that are there.

I boiled this whole thing and closed the lid and put everything in place. I was not happy with the result, I thought the sound would be at least somehow bass at the rpm, but then it turned out that it was not enough to remove one partition and cut off part of the pipe in the resonator, it was necessary to cut 2 partitions. Nov decided to do direct flow in general, i.e. try how it will be with forward flow, I still had nothing to lose!

healthy! I removed the catalyst for myself and all the norms were not errors, nothing did not light up, I also had qr20 two windows blew out the current for a long time and so the norms

but after knocking out the catalyst, my chain thundered, I had to change the motor.

since the chain costs 10,000+ work 10,000 and took a motor with 73,000 mileage for 25,000 and threw it in the garage

you better take off as a native katalik knock out

top without clutch but it would be faster with clutch

Anton will very much wait for the video on knocking out the catalyst! P.S. on the forums they write: “if the lambda probe (which is located after the catalyst) is placed outside the muffler, the on-board computer will not give an error. Thanks for your videos!

Hello Anton. Why don't you answer in a personal on the drive? Waiting for an answer. Also wrote to the mail.

Brothers, help me figure out the problem. Not for no reason the car stopped gaining momentum .. I mean, press on the gas, but they do not rise above 3000 !! Moreover, after 2500 there is such a terrible detonation that the dvigon is trying to jump out. I have already changed the candles, and cleaned the flap, and torn the catalyst. shorter seams. I sin on the sensors .. they are responsible for the operation of the engine, in fact, there are only three (I think so) the oxygen meter, the position of the camshaft and crankshaft .. Maybe someone has encountered such a problem ?? What to do.

Hello Anton, tell me please, I have some kind of iron sound, I don’t know what to do. Sound from the top of the cover

It so happens that a strange unusually loud rumble is suddenly heard from under the car. And then even an ignorant driver understands - the problem with the "glushak"! Most often, burns appear, less often the elements of this node come off from each other.

But, fortunately, most of the breakdowns can be fixed by making a do-it-yourself muffler repair. The main thing is to understand which of the following reasons led to the malfunction:

hitting an obstacle that damaged the muffler;
corrosion, burnout of the unit due to the constant effects of harmful substances from exhaust gases, as well as their heat;
constant strong exhaust pressure;
large drops in ambient temperature.

If such a nuisance happens, you should not postpone the repair of such an important assembly unit, so as not to deafen others and yourself with a nasty noise. In addition, the unit may simply fall apart. Next, we will consider how to make a do-it-yourself muffler repair using the example of different cars.

In many cases, a car enthusiast can do without a welder, electrodes and a car service. However, this option for eliminating the problem is most often not pleasing with the subsequent durability. It is of a temporary nature, for example, if there is no time to go to servicemen.

Let's consider repairing a muffler with our own hands using the example of a ZAZ Tavria car.
Useful for us:

wrenches;
sandpaper;
set for cold welding;
a piece of tin;
clamp with threaded tie.

We begin to repair the muffler of the Tavria car with our own hands from the inspection pit.

First of all, we determine the place where gases break through. It's good if the hole is outside. Next, we describe how to close just such a hole.
First, we dismantle the entire assembly, for which we unscrew the fasteners.
So, the unit is in front of us. In Tavria, it is simple: there are two chambers inside, one of them with a diffuser. We clean the hole thoroughly with sandpaper. This must be done without fail, otherwise there will be no sense.
After mixing the components, apply cold welding with fingers in a glove.
We tighten this place with a clamp around.
We install the unit back.

In fact, the recommendations for many other cars also look like. After all, we specifically described these recommendations in general terms, which help to repair the muffler with our own hands, but only with cold welding.

Another thing is when the front pipe fails. Here it is unlikely that you can help with local repair of the exhaust pipe of the muffler with the help of some cunning means and with your own hands. There is only one way out - replacement. After all, these "pants" - receiving pipes - perceive the very first powerful blow of exhaust gases. The load is so great that local fittings will only help you get to the garage.

To replace "pants", for example, on a "classic" VAZ, you must have:

spanners;
penetrating lubricant.

Also read about replacing the propeller shaft cross and repairing the starter with your own hands.

We dismantle the rear part of the muffler.

We detach the resonator.

We unscrew the clamp bolt that holds the front pipe.

We open the hood, then unscrew the nuts securing the intake pipe to the exhaust manifold.

We remove the defective part, as well as the gasket.

We install a new part together with a new gasket according to the reverse sequence.

The main thing here is not to forget to process threaded connections that cannot be loosened with a penetrating grease of the "vedashki" type. And after processing, wait a few minutes. Although it is possible that some nut will have to be carefully cut off with a "grinder", because all elements of the exhaust system work in extremely harmful conditions, so they quickly stick to it. And now we will consider repairs on several more cars. Take Nissan, for example. If the gasket of the unit burns out, it is better to replace it. For Nissan Note, like other cars, do-it-yourself repair of the muffler gaskets does not make sense.

But repairing the exhaust pipe of the muffler with your own hands without welding is just appropriate. For this you will need:

ceramic sealant;
tin tape;
scissors for metal;
pliers with fine ends;
hammer.

Be sure to clean the leaky place. The assembly does not need to be removed from the vehicle.
Apply a generous amount of ceramic sealant with your fingers (we use gloves to protect your hands) directly on the hole.
We wrap this part of the pipe with a tin tape. We cut off the protruding ends of the tape, leaving 2 centimeters from the pipe.
Bend the remaining ends with pliers.
We knock the bend with a hammer so that the clamp obtained in this way squeezes the pipe tightly.

With the result obtained, you can travel more than one hundred kilometers.

In addition, we will consider repairing a muffler at a Gazelle. Let's say the resonator is broken. This element of the system uses a tube with many holes. Due to them, low frequencies are extinguished - the gas, passing through many holes, rubs against itself.

It is not difficult to repair the muffler resonator with your own hands if the outer wall is leaky. Suppose the place where the tube comes out of the resonator is burnt out. Dismantling the unit from the car is practically not required here. For our work, we take the following things:

cold welding;
sandpaper.

You need to do some simple manipulations.

We carefully clean the gap that appears with sandpaper.
We hammer it abundantly with the composition, mixing the components. We also spread a large layer on top, gloves should be on the hands.
We give the squad time to grab.
Sand lightly with sandpaper.

With such a repair of the muffler with your own hands and without welding, you can also drive a decent number of kilometers.

However, if such a muffler repair turned out to be short-lived, it is better to call in for a service. There you will definitely have major welding works, this will allow you to travel hundreds of thousands of kilometers without thinking about the release. Moreover, everything will not cost so much.

The cost of welding, together with the removal of the element and its installation back from the masters of the car service, is indicated in the table, relative to different large cities of the Russian Federation. Here is the table.

A flame arrester is a device that replaces the catalyst for the exhaust system of a car. An integral part of the flame arrester is an oval resonator, which acts as a component of the muffler. Many users of the Nissan Primera car are interested in replacing the catalyst, which makes sense, to explain the purpose, functions and installation of the component being studied.

Having dealt with the terminology, it is necessary to understand the functions that the flame arrester performs on the Nissan Example P12. The main task of the device is to reduce the temperature of the exhaust systems of the muffler. Reducing the temperature helps to optimize the performance of all components in the exhaust.

The flame arrester has practical properties that are capable of stabilizing the operation of the vehicle's exhaust system. The main properties of the device are as follows:

Support for extremely high temperatures due to combustion chamber gases.
High strength thanks to the metal sheath.
Double casing to withstand the pressure of gases from the exhaust system.
High level of resistance to mechanical destruction.
Adjustable volume of the flame arrester, affecting abrupt starts of the car.

The creation of a flame arrester requires careful checks and careful production. It is crafted from rare materials to maintain high temperatures along with protection from exhaust fumes. However, mechanical engineering specialists have developed a good alternative in the form of a catalyst, which is a more expensive device with similar properties.

Replacing the flame arrester with a catalyst is not always the best solution, since there are a number of factors that make every user think:

A catalyst is an expensive solution.
The service life is reduced due to the use of low-quality fuel.
Subsequent complication, obstructing the passage of gases from the exhaust system.
Decrease in machine power (especially noticeable at abrupt starts).

There are other cases involving the replacement of a catalyst with a flame arrester. Such a technique is used to stabilize the pressure in the exhaust system of a car, and the catalyst contributes to the rapid wear of the equipment, since it uses the principle of pressure compression, which increases the power of the vehicle. Some users buy expensive flame arresters on purpose to provide the stabilizing effect of the exhaust system.

The first and most frequently identified cause is the internal resolution of the flame arrester elements. Separation occurs within the device itself, causing the flame arrester to vibrate. Most often this is manifested in a shaking, tapping sound when the car starts abruptly.

The next reason is the long stay of the exhaust system at high temperatures. The problem is relevant for fans of sharp maneuvers in the form of overtaking, starting from a standstill. A knock on the engine and a decrease in vehicle power will be a sign of a breakdown.

Summarizing the problem of the malfunction, it should be said that the main cause of all breakdowns is revealed in the detection of corrosive effects leading to the breakdown of individual components of the muffler, then leads to accelerated wear of the engine, negatively affecting the service life of the car.

Having found out the reasons, it is necessary to diagnose the equipment for more specific measures to solve the problem. First, electronic diagnostics are carried out using computer equipment. Most relevant for modern cars.Computer hardware - a scanner that calculates error codes, with the help of which the subsequent cause of a malfunction is identified.

The next stage is an inspection by a mechanic who checks the flame arrester for defects and integrity. Further, if problems are found, repairs are made. The price depends on the degree of breakdown, but experts always prefer to change the flame arrester completely.

Concerning Nissan P12 Examples, it is difficult to find the necessary flame arrester. Recommended models are advised to choose from a range of QG15 or QG16 engines. The first step is to uninstall the old worn out catalyst. First, the machine is lifted using an auto-lifter, then everything you need is unscrewed using a 12 key and a hammer. Our car service will provide high-quality disassembly of the old catalyst, followed by replacement with a flame arrester.

As a rule, a pipe with a diameter of about 40-60 mm is taken, depending on the engine. There should be two pipes, then our specialists perforate them with drills, creating walls up to 2 mm thick, then perforate them up to 6 mm. The ends of the pipes should be in the form of petals, allowing the exit and entry of the exhaust gases. In addition, emphasis is given. A stainless steel surface is used as an insulating agent, which is applied to the pipes. The installation is completed by sliding the pipe inside the catalyst. The work ends after all parts are returned to the buyer. The correct installation is checked by turning on the engine.

Having shown a detailed repair of the Nissan exhaust system components P12 Examples, it is necessary to summarize that experts can offer the buyer a more expensive option - a completely new catalyst without the use of third-party metal parts. By purchasing a new catalyst, the customer will be able to solve the problem with the exhaust system, but at the same time the costs will increase significantly.

As a conclusion, it should be said that the flame arrester is an excellent option for budget cars that have traveled a large number of kilometers. In the case of the Nissan Examples P12, replacing the flame arrester is inexpensive.

Installing a flame arrester is a matter for qualified specialists, so it is better to entrust the work to an experienced car service.

high noise level;

ingress of exhaust gases into the passenger compartment;

increased fuel consumption;

decrease in engine power.

The exhaust system consists of several parts, each of which plays an important role. These include the front pipe, catalyst, resonator and the muffler itself. The main functions that it performs are noise suppression and reduction of the emission of harmful gases. Also, there is often a corrugation on the front pipe to reduce vibration. A malfunction of any part of the exhaust system can affect the condition of the entire car and many of its other parts in particular, therefore, it is necessary to regularly diagnose this element of the car.

The very minimum looks like this:

1.Inspection pit;
2.Cut-off tool (hacksaw for metal or "Bulgarian" power tool);
3. Welding machine and power source (there is no difference, you will do this with electrodes or a semiautomatic device).
This can be done by the specialists of our company, who are professionals with a capital letter. They will do this work, which is accompanied by welding, accurately and efficiently.
It is from the weld that how the corrugation will work, and, accordingly, the rest of the exhaust system will depend.
The seam must maintain the strength and flexibility of this system so that your car will serve you for many years.

Silencer repair sooner or later may be necessary for most drivers. This element can fail for various reasons - mechanical wear due to a constant flow of gases, defects in production, impacts on the ground, and so on.
The main task of the Nissan Primera (P11), (P12) Diesel 2000 TDI, 1900 8V dCi, 2200 DCi car muffler is to reduce the noise level. This is done by converting sound energy into heat energy. The device may have one drawback - due to its design, it slightly complicates the outlet of exhaust gases, which reduces engine power. It is noticeable to the naked eye that cars without a muffler not only make a lot of noise, but also go faster (albeit not much).
- decrease in engine power (deterioration of acceleration dynamics, decrease in maximum speed), coupled with increased fuel consumption
- Difficulty starting the internal combustion engine (it took longer to start)
- pungent poisonous odor from the exhaust system
- extraneous noises are heard from the catalyst (ringing, rattling)
- shows diagnostics with corresponding errors indicating ineffective operation
If there is any suspicion of improper work - come, we will conduct a free diagnosis. We will make the necessary repairs if necessary.

We offer the most reliable option - replacing the catalyst with a high-quality factory-made flame arrester (see figures) made of two-layer stainless steel with the installation of a controller for adjusting the readings of the lambda probe (blende) of our own production.

There is a misconception that after removing the catalyst and replacing it with a flame arrester, the Primera will work louder, no matter what flame arrester is installed. Flame arresters of the latest generation work as quietly as catalysts, and sometimes even quieter if two or three reflective, cooling and noise-absorbing chambers are made inside, and 2-3 types of packing are used to extinguish noise, temperature and pressure. The highest quality stuffing is made of stainless wire and Kevlar: it is not afraid of high temperatures and due to its strength it is not blown out. It absorbs noise three times better than basalt (the most common).Products with such a gasket cool exhaust gases better than their counterparts, and serve 10 times longer.

Comment. We do not replace universal catalysts for Nissan Primera due to their unsuitability for our gasoline, coupled with low quality performance by manufacturers for the sake of low prices (mainly China).

At the time of the first recording, I had a car for a year and a half. Some of the breakdowns are described here.

The check caught fire, error 1065. I dropped it, it didn’t appear anymore.

Air conditioner

I went to fill the air conditioner. The specialist looked it turned out that the compressor did not turn on (but the light came on). He began to look at the fuses, pulled out something, inserted it back. After that, the car stopped starting. An electrician came, began to look for a malfunction, watched the signalization, a gasoline pump, and so on. They even poured gasoline (my arrow was almost at zero). The infection does not start ... They fiddled for about an hour. Such is not a clever situation ... In general, it turned out to be in the oxidized fuse connector 20 IGN COIL. The air conditioner pulled it out - probably thought it was in charge of cooling.

Visited VIRBAC for diagnostics.
What worries:
1. Hum when driving. Sound from the front, but not clear from which side. It seems to me that the box itself is buzzing. And nifiga.
2. Vibration on the clutch pedal when pressed. I think something with a clutch. This problem is from the date of purchase. Now it is getting stronger.
3. In general, vibration throughout the body.
1. Right wheel bearing.
2. 3. Killed engine mountings.
In addition, for replacement, steering tips and front upper arms.
The power steering pump and the rack leaked, it does not particularly affect the oil consumption (I added a hundred grams for several thousand km), but everything is wet. A / C compressor is leaking.

2014-07-27. 303650.

The air conditioner refused to cool. The master said that the khan to the compressor and the radiator were flowing. I managed to see this for myself. In special glasses and with a special flashlight, these smudges are very clearly visible, just like in the movie a predator, the blood of an alien - such green spots!

I have been driving for a long time with a snarling muffler. The sound, of course, is far from the same as that of the forward flow, but you can hear it well. And not so long ago I caught the resonator for a piece of iron. Now growls decently. We'll have to fix the exhaust system. Change the collector-intake pipe gasket and weld the muffler in the area of the flange. I bought some pieces of iron.

256113 BOSAL gasket collector-pipe 126r.

I will not climb myself, there is a fear that the bolts will break off - I will have to drill out, and this is still the hemorrhoid. And I don’t have a hole as such.

Repaired the muffler. There is silence in the cabin. The feeling of a new car. Beauty. The motor becomes audible when the rpm approaches 3500. What was done:
- Replaced exhaust manifold gasket
- Bolts, one did not unscrew (welded on a nut and unscrewed)
- The muffler flange has completely rotted; it has not lain under repair; it has been replaced by a coupling.
The renovation took almost 2 hours. I gave 2000 for the work. It's good that I didn't climb myself, otherwise I would have been digging around all day.

But this is all nonsense. A miracle happened. The engine now has throttle response! Yes Yes! The car is really rushing! And that's not all. The car now starts smoothly! And this is not a placebo effect. Blah, these two differences really brought me the whole brain, which I just did not think. It looks like there was air leakage in the area of the exhaust manifold, and then lambda goes ... What information was transmitted to the brain can only be guessed at (I think the mixture was depleted because there was no gas burner). Once again I am convinced that the car needs to be repaired as soon as there is a malfunction, and not to drive for months.

Among other things, you need to go for a drive, watch what happens next.

Everything returned to normal. Gradually, the dynamics fell, the idle speed is overestimated (a little over a thousand). We must look for the suction.

2015-01-08. 309900.

Frost -20. The car will not start. I changed the candles, gasoline comes in, there is a spark. I checked everything I can. I started it only with a pusher. And on the eve the temperature was the same - everything was in order.

2015-01-11. 310000.

Suddenly there was a problem with the wipers. They don't turn off! They start working when the ignition is turned on and do not turn off until you turn off the ignition. The pause is not regulated, only the frequency of the wipers changes. Having climbed the forums, I came to the conclusion that the motor is not working properly. Ofigel from the price tag of 18,000 at the moment. There are no analogues.

For a couple of days, the janitors lived their own lives: they could suddenly turn on and not turn off. Or they could have turned off. Not a pleasant enough breakdown. You go glass is dry, but they work. And they creak, so disgusting ...

I disassembled the steering column switch - I did not notice anything special.

I don’t know what exactly influenced it, but the malfunction disappeared after that.

For about a month, a rumble has been heard from under the hood - the bearing of the air conditioner compressor is dying.

Anton, thanks for the vidos. I have a similar problem. Only the protection was bent. Khan thought to the pillows of the internal combustion engine. Straightened the protection, the vibration was gone. But some hum remained. I will watch this site which is in the video. Where is the promised vidos about candles? If you change the dimensions, please show me

There is also such a problem, but for some reason I can't believe that this is because of the pillow. The first time I saw your video, T. K followed the link in the drive. And I don’t understand you have been friends with the Prul for a long time? If yes, then what for you put febest, it's a slag, well, in general, catch the like

Anton, where does the information about the arrow come from? IMHO, it is not written anywhere that it is for the engine. In my opinion, it points to the right side r in the direction of travel, that is, it should be directed back from what is shown in the video.

And here I got a kapets like. All my cars are just zhopovoz. I understand nothing. Well, apparently, it is simply not given. More precisely, there is no time to delve into and desire. I wanted Diana for a long time. Bought. White pearl. One hostess. Full minced meat. But when buying one shit confused. When starting off and turning the steering wheel, there is some kind of movement. And not a crunch. And I don't even know what to call it. The roar is continuous. I went to the new advertised hundred. These dicks climbed. S experts for half an hour. PPC diagnosis to pump gur. I bought a new one. Put. I leave the ditch and nothing has changed. I threw the bream on the master and drove home. What you need to pay attention to. In our city there are simply no traveling specialists. Maybe someone came across? tell

Who set the dis? The man is trying. The video is useful. What kind of asshole put the diz on?

Thanks! Anton, I also have such a problem, I was looking for and could not find this problem in order to get rid of such an unpleasant sound during overclocking, but everything turns out to be simple and obvious.
