Audi A4 exhaust valve leakage does not burn engine oil

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.

There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, but now there is a plan to solve the problem of burning engine oil without dismantling and repairing, which can be understood by taking a look.

The main reason for burning engine oil

There is a problem with the fittings, the wastegas valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

If the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil life cycle is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

What is piston ring seizure

Stagnation starts from the oil circuit, the oil bears the temperature at 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 fail 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, and a cylinder stuck is a liter of oil for 5000 kilometers, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders are stuck, and it will become a liter of oil for 1000 kilometers or even hundreds of kilometers.

There are two ways to solve the problem of burning engine oil

Overhaul. PNF restoratives.

Benefits of this one:

In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome. First of all, you need to find out the reason for your burning oil, oil circuit blockage, carbon deposits, piston ring stagnation can be repaired with PNF repair agent, there are many riders who have successfully repaired through PNF repair agent, you can refer to it.

Abnormal. 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.

Abnormal. If it is only oil leakage, it is a normal and common phenomenon, and the sealing ring is generally replaced.

The main causes of engine oil leakage are as follows:

1. The oil pan gasket is damaged or the screws are loose and leaking;

2. The oil pan oil drain screw plug liner is damaged, leaking or loosening and leaking;

3. Improper assembly of timing gear cover gasket, damage or loose screws and oil leakage;

4. The engine bracket plate is deformed or the gasket is not tightly sealed and leaks oil;

5. The valve chamber cover gasket is not tightly sealed and leaks oil;

6. The front oil seal of the crankshaft is damaged and leaks;

7. The oil seal of the crankshaft is damaged and leaks;

8. The oil return thread at the rear end of the crankshaft is blocked by dirt and leaks oil. Oil leakage due to improper processing of oil return thread or out-of-tolerance coaxiality between the thread journal and the oil seal seat hole;

9. The rear cover of the cam bearing is not strict and leaks oil;

10. The rocker arm chamber cover or the lever chamber cover is not strict and leaks oil;

11. The oil radiator is not tightly sealed and leaks;

12. The oil filter is not tightly sealed and the oil leaks;

13. The sealing of the bearing hole of the distributor shell is not strict and leaks oil;

14. The oil pump liner is damaged or the screws are loose and leaking.

Don't overhaul the cylinder if you don't pull it. My car, 1000 kilometers of one-liter engine oil, EA888, 9W kilometers, replaced the waste valve, the valve oil seal is fine, the cylinder wall is not strained, according to the rider used by the company to burn the oil repair agent after four times, the current 7000 kilometers of oil in the middle of the oil dipstick. It's a success.

The solution to the Audi A4L burning engine oil too much.

The engine of the Audi car is relatively easy to burn the engine oil, which is a design loophole of the designer, and many German cars have this problem, and you are not alone.

First of all, you need to confirm the reason for burning engine oil, and the main reasons for burning engine oil are two aspects.

First, there is a problem with the accessories, the waste gas valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

The second is that the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil service life is too long, and the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Causes of piston ring seizure

In fact, the treatment principle of piston ring stagnation should start from the oil circuit, the reason for the stagnation is the beginning of the oil circuit, the oil bearing 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, and a cylinder stuck is 5000 kilometers of a liter of oil, at this time, the working conditions of other cylinders will also begin to be bad, and soon the 4 cylinders will be stuck. 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 engine oil in Audi cars

First of all, you need to check the accessories. If it is a damage to the accessory, the accessory needs to be replaced. Check if there is a serious problem with the cylinder. If there is a serious situation of pulling the cylinder, you can directly choose to overhaul the engine and replace the middle cylinder. If there is no pull cylinder or slight pull cylinder, you can do not rush to overhaul it first.

Burning engine oil is not a terminal disease, there is a way to solve it, and it is not necessary to overhaul the engine. Overhaul is self-evident on engine damage, and many car owners will still burn engine oil after overhaul. At present, the solution to the problem of burning engine oil has matured, so there is one more option for the treatment of burning engine oil!

As long as you use the general burning oil repair agent for 4 times in a row and drive more, you can clean the carbon deposits on the top of the piston and release the piston ring.

The solution to burning engine oil in Audi link.

This thing must be abnormal, no matter what car engine leaks, it must be abnormal, you have to check where the engine is leaking oil? So what is the problem to focus on at this time? Why does engine oil leak?

Specifically, if you don't know how to inspect, you go to some repair shops or match points for detailed inspection and maintenance.

Hello! The engine of Audi A4 will have the following places that will cause oil leakage in the case of a long period of use: 1. Valve chamber cover pad, rubber aging will lead to oil leakage after a long time, if it is not replaced in time for a long time, then the amount of oil leakage will increase.

2. The front and rear oil seals of the crankshaft of the engine are also made of rubber, and they will also age and crack. 3. The sealing gasket of the oil pan. These are the ones that need to be checked and replaced in a timely manner, and many of these reasons will exist!

An engine oil leak is definitely not normal!

1. Start the tachometer, the speed should exceed 1000rpm, the idle speed is unstable, listen to the sound, you can know that the waste valve is broken.

2.If the wastegate is damaged, the dashboard will show that the engine fault light is on, but this will not affect continued use. Only after the wastegate has been replaced with a new wastegate and the faulty lamp has been removed can the wastegate be restored to normal.

Exhaust valves are actually referred to as "oil separators" or "pressure control valves". The exhaust valve of the engine is mainly responsible for controlling the exhaust gases generated when the car is burned. Due to the operation of the exhaust valve, the car will reduce the emission of nitrogen oxides, which is beneficial to the environment.

At the same time, because if the amount of exhaust gas involved in combustion is too large, it will affect the power of the engine, so the exhaust valve can also ensure that the engine has enough power.

Extended data: Exhaust valves are also called oil separators and pressure control valves. The separation between the compressor outlet and the condenser inlet improves heat transfer in the condenser and evaporator.

Working principle of waste gas valve: After the high-pressure gas (gaseous working fluid and lubricating oil) from the compressor enters the waste gas valve, it enters the guide vane of the waste gas valve and flows along the spiral of the guide vane. By centrifugal force and gravity, the lubricating oil is separated from the working medium gas and left along the inner wall of the cylinder.

The working medium is drawn from the central pipe by means of a multi-void baffle and the waste-gas valve.

The separated lubricating oil is concentrated in the lower part of the oil separator and can be discharged at regular intervals, or it can be automatically returned to the crankcase of the compressor using a ball valve.

If there is oil in the intake branch pipe of this car, if this phenomenon occurs, this is to check the exhaust valve on the engine to see if there is a problem, if it is damaged, there is no way to filter it normally, and the oil will also run into the intake branch. It is necessary to check it, if there is no problem, it is necessary to check the turbocharger, if there is a problem with the oil seal of the turbocharger and there is oil leakage, the crack will also blow the oil into the intake branch pipe during this work. Both of these locations need to be specifically inspected, and if there is a problem, then it is necessary to replace the parts or repair the source of the repair.

If there is a large amount of white smoke coming out of the exhaust pipe, and the engine is shaking, idling is unstable, etc., it is very likely that the car exhaust valve is damaged.

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 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 is concentrated in the lower part of the oil separator and can be discharged periodically, or the lubricating oil can be automatically returned to the crankcase of the compressor by using a float valve.

1. If there is a large amount of white smoke coming out of the exhaust pipe, and the engine is shaking, idling is unstable, etc., it means that it is very likely that the exhaust valve of the car is damaged;

2. When checking the fault of the engine idle instability, if the engine speed does not decrease but rises when the fire is broken off a cylinder, it should be immediately thought that this is caused by the failure of the exhaust gas recirculation valve to close tightly;

3. Causing a large amount of blue smoke to come out, at this time it is a more serious phenomenon of burning engine oil. Therefore, car owners must check and repair in time when they encounter the above situations. (Photo by Hui Pai: Chen Yalan) @2019
