What s wrong with the new Sylphy exhaust valve exhaust oil?

1.Use oils that are of poor quality or do not meet the viscosity grades.

2.A low oil quality grade can lead to increased wear.

3.If the fitting gap between the piston ring and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning the engine oil.

4.Oil burning caused by excessive oil filling. While.

5.Turbocharger oil leak.

6.There is a leak in the valve seal, which is the leakage of oil into the combustion chamber through the valve seal.

Exhaust valves are also known as oil separators and pressure control valves. Installation between the compressor outlet and the condenser inlet improves heat transfer in the condenser and evaporator by separation. The separation between the compressor outlet and the condenser inlet improves the heat transfer between the condenser and evaporator types.

For systems where lubricating oil and working fluid are less miscible, the oil separator is even more important.

The working principle of the exhaust valve: the high-pressure gas (gaseous working fluid and lubricating oil) from the compressor enters the exhaust valve, enters the guide vane of the exhaust valve, flows in a spiral shape along the guide vane, and separates the lubricating oil from the working fluid gas by centrifugal force and gravity, leaving it along the inner wall of the cylinder. The working fluid gas is drawn out of the exhaust gas valve by the central pipe through the multi-empty baffle.

The separated lubricating oil, concentrated in the lower part of the oil separator, can be discharged at regular intervals, or the float valve can be used to automatically return the lubricating oil to the crankcase of the compressor.

Most of the Nissan Sylphy engine oil is caused by the piston ring being trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. When the oil enters the combustion chamber to participate in combustion, more carbon deposits will be formed, which in turn will lead to the aggravation of the burning of engine oil, forming a vicious circle.

In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

Four reasons why you burn engine oil.

A ...If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, detergents are used at will, and using detergents and effective detergents are two different things;

IIThe antifreeze replacement cycle is too long or not changed at all;

IIIThe oil change interval is too long;

IVLong-term or often short-distance driving.

The above four points of the vehicle that burns engine oil must be occupied by one or all four points.

How the piston rings are stuck.

The principle of piston ring stagnation should start from the oil circuit, the oil temperature is 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time. It becomes a liter of engine oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.

The new Sylphy wastegas valve drain oil is faulty and needs to be replaced.

The exhaust gas valve is equivalent to an oil-air separator, which only sucks exhaust gas and does not absorb oil when it works normally. When the exhaust valve is damaged, it loses the function of oil and gas separation, and sucks in the oil at the same time as the inhalation, so that the oil enters the air intake and combustion chamber.

Engine oil leakage may be: 1. Poor quality, material or workmanship of accessories. 2. Improper assembly, unclean mating surface, and installation not in accordance with the operating procedures.

3. After long-term use, the sealing material is worn out too much, and it is aging and deteriorating, deforming and failing. 4. Excessive lubricating oil is added and the oil level is too high. 5. The joint surface of parts is uneven.

6. The breather plug and check valve are blocked. In order to avoid affecting the use, it is recommended that you contact the after-sales service as soon as possible. If it is said that the contact after-sales service has not been handled, it is still through the car quality network to feedback your problem.

There are two basic scenarios for the causes of oil leakage in a car engine:

1. Oil leakage from automobile engine. There are relatively clear oil stains on the surface of the car engine shell, if the oil stains are cleaned up at this time, and the oil stains on the shell are found soon after, and even some serious gasoline is still falling like water droplets, this problem should be sent to the car for maintenance as soon as possible.

2. Oil leakage from automobile engines. There is only a small amount of oil stains in the engine shell, which means that the engine oil leakage is not particularly serious, and the oil leakage at this time is not obvious and small, and it has little impact on the engine at this time.

The most direct and effective way is to change the sealing ring, the urban roads are congested, and the stop-and-go needs to be constantly shifted; Nowadays, there are more and more gears in the car, resulting in more gear shifts, greater working pressure in the gearbox, and higher temperatures, which accelerates the aging and deformation of the rubber at the gearbox seal.

There is also a small part of it because the transmission oil is added too much, which increases the resistance of the transmission gears. When the gears of the transmission are strained, problems in the box will also increase, which can lead to loose oil seals and eventually oil leaks. Therefore, it is necessary to refuel according to the maintenance manual.

Sudden large-scale oil leakage, such as yesterday was fine, today suddenly found that there is a large pool of oil on the ground, often caused by the oil pan bottom deformation, rupture or the filter is not tightened. When such a problem occurs, you should immediately check the oil balance and go to the repair shop to check it as soon as possible.

Extended Information: Causes of Engine Oil Leaks:

1. Engine oil leakage caused by poor sealing of valve chamber cover gasket, oil radiator, oil filter, distributor housing bearing hole, rocker arm chamber cover, cam bearing rear cover and engine bracket plate deformation.

2. When the front and rear oil seals of the crankshaft and the oil pan liner of the automobile are damaged to varying degrees, it will also lead to engine oil leakage.

3. If the timing gear cover gasket of the car is not properly operated during installation, or if it is damaged to a certain extent, the screws are loose and leaking.

Handling of engine oil leaks and hazards:

1. The solutions taken for different models are also different, some engine oil leaks do not need to remove the cylinder block, but some parts of the oil leakage cylinder block need to be removed. It is best to deal with it according to the specific situation of the car.

2. The engine oil leakage of the car is not a big fault, and we do not need to repair the car for the time being. However, if there is an oil leak in the engine, it needs to be carefully inspected.

3. The engine oil leakage of the car will bring certain damage, the most important of which is to cause the car to lose a lot of oil, and there is a waste of it. If it is severe, it may cause damage to the engine due to insufficient oil.

Hello, I am your exclusive technician, attentive, careful, attentive to answer your car questions, for you to find the solution to the problem corresponding to the segment of the limb and the solution, will provide you with a satisfactory answer! I hope this service can help you, if it is helpful to you, I look forward to your praise and attention. The Nissan Sylphy exhaust check valve is located on the lower right side of the intake tract and the EGR body is usually located on the right side of the intake manifold.

The EGR valve, also known as the exhaust gas recirculation valve, is a mechatronics product installed on the engine to control the amount of exhaust gas recirculation in the air intake system, and is a very important and key component in the exhaust gas recirculation device. Its function is to control the amount of exhaust gas entering the intake manifold, so that a certain amount of exhaust gas flows into the intake manifold for recirculation. The EGR valve is usually located on the right side of the intake manifold, near the throttle body, and is connected to the intake manifold and exhaust manifold, and the vacuum tube controls the degree of opening of the valve, which determines the amount of exhaust gas transmitted to the intake manifold.

It reduces the combustion chamber temperature, improves the engine work efficiency, improves the combustion environment, and reduces the burden on the engine by directing the exhaust gas discharged from the engine combustion to the intake manifold to participate in combustion, effectively reducing the emission of carbon monoxide compounds, reducing knocking, and prolonging the service life of each component. The Nissan Sylphy has better comfort and is more suitable for family members.

Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car, the damage of the new Sylphy exhaust valve will have the following symptoms, the first word is the increase in oil consumption. The damage of the exhaust valve will lead to the decline of the oil filtration function of the aircraft method, and part of the oil will enter the intake pipeline to participate in combustion, resulting in an increase in oil consumption. In the third aspect, part of the engine oil is involved in combustion, resulting in the exhaust gas is not up to standard, and the exhaust gas is smelly.

1. Remove the vacuum line.

Carefully remove the rubber vacuum cord connected to the EGR valve. If it becomes brittle, broken, or worn. Get a new one.

2. Disconnected wire harnesses.

If your EGR valve has an electrical connection, carefully disassemble it.

3. Pull out the EGR valve.

Remove the screws attached to the EGR valve. If you find it difficult to twist the screws when you remove them, tap them gently with a small wooden block or hammer.

4. Take out the gasket.

If your gasket looks good (no tears, frays, or breakage), you can continue to use it respectfully. If it's problematic, install a new one.

5. Immersion EGR valve.

Cleaning the EGR valve takes only one or two steps. It depends on how long and how far you need to drive the car. First, place the EGR valve in the bowl with the vaporizer cleaning liquid. Soak it overnight if you can. Skip this step if you don't have time.

Note: If your EGR valve has an electrical connection, do not immerse that part in the cleaning solution.

6. Clean the EGR valve manually.

If you've soaked your EGR valve overnight (if you can), use a small brush to clean its pipes, openings, smiling wide surfaces, etc. With just a cleaning brush, you can clean every part of the EGR valve in place.

Note: When washing by hand, wear protective gloves and protective glasses. Vaporizer cleaning fluid is a dangerous thing.

7. Reinstall the EGR valve.

Now you can reinstall the clean EGR valve. Don't forget to reconnect the vacuum hose and electrical connections.

Summary. Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

In this case, if the position of the throttle is oily, it is necessary to check the waste valve, and this phenomenon will occur after the limb abrasion may be enlightened, and the waste valve needs to be checked, if it is not done, then it needs to be replaced.

The wastegas valve I have changed to a new one and it is still the same throttle organic oil.

Then you need to check this valve seal to see if there is any problem.

Yesterday I had a failed motive just completed the overhaul, the exhaust valve and valve seals are all new Nian Di, and now the car starts the throttle or the old nuclear organic oil, there may be other problems? The repair shop said to change the valve chamber cover to a new one, and this problem is related to the valve chamber cover.

Yes, you need to look at this valve chamber after it is replaced.

In addition to the valve chamber cover, the waste gas valve and the oil seal, is there anything else that is broken, which will cause such a problem?

Other things that don't lead to this phenomenon are mainly these aspects.

Okay, thanks for the answer from the experts.

You are welcome.
