What to do if the BMW 3 Series burns engine oil After replacing the valve oil seal, the exhaust stil

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 cause the engine oil to burn, so that the vehicle appears: 1. Carbon deposition occurs in the combustion chamber, which makes the air ring of the piston ring stuck and poor sealing. 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.

1.First, check the reason for burning the oil-related accessories and eliminate the problems of the relevant accessories.

2.Through the first step to eliminate the problem of related accessories, it is determined that the piston ring is stuck and causes the oil to burn.

Determine that the piston ring is to be deduced in reverse》The repair of burning oil is reversed to determine the reason for the piston ring, so it is very simple to check the external accessories, and the second can be determined to be the piston ring, so as not to take a detour.

1. There is a problem with the accessories, the waste valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

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

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.

It is recommended to use the additives that can release the piston ring once for 5000 kilometers, which can well prevent the piston ring from stagnation, and can also clean the oil circuit, which will not lead to the long-term high temperature of the oil circuit affecting the working condition of the engine, and 20w kilometers will no longer cause the problem of burning engine oil due to piston ring stagnation.

See BMW car friends in the case of already burning engine oil does not need to repair the cylinder, let alone dry ice, only one way can get the oil burned, the car does not delay the use of the car at all, so that there is no detour, and the car that burns the engine oil can be done well, so that the car that begins to consume engine oil and becomes larger is no longer a problem.

The causes and solutions of BMW burning engine oil.

Blue smoke from exhaust gas is related to valve oil seals, but if it is an oil ring in the engine, the air ring is seriously worn or partially missing, it will also burn the engine oil and emit blue smoke, in short, burning engine oil is not a small problem, the cause should be checked as soon as possible, and it should be solved as soon as possible, this problem will only become more and more serious if it is not solved.

The reason for this is that the valve oil seal can only be replaced by the aging of the valve oil seal, other methods are useless, but if you want to improve the power immediately, you can use a good oil to continue, I myself use GT magic red engine oil imported from Germany, PAO fully synthetic power enough, the speed is increased quickly, the emergency use is very effective, and the quality of this oil is good and can also alleviate the problem of burning engine oil.

The main reason for burning engine oil in this car is that the piston ring is stuck in the piston ring, and the main problem of piston ring stuck is the high temperature of oil combustion. As long as the problem of piston ring stagnation is solved, the engine oil will not be burned, which is very easy to solve, especially for cars with very small mileage, which does not need to be overhauled and does not need to replace the middle cylinder.

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.

Work something out. It is recommended to use a PNF repair agent for 5000 kilometers to release the additives of the piston ring, which can prevent the piston ring from being stuck well, and can also clean the oil circuit, which will not lead to the long-term high temperature of the oil circuit affecting the working condition of the engine, and 20W kilometers will no longer cause the oil to burn the engine due to piston ring stagnation.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

Hello, this needs to focus on checking whether the oil pan oil bottom screws are fastened in place. There is also whether the oil filter is tightly in place If it is not installed properly, it will cause the oil to leak out, and then a large amount of white smoke will appear. If there are no obvious road marks, it is necessary to check the spark plug and see if it burns to see if it is black or white.

As you said, this situation is most likely caused by not seeing the installation in place. If you have any other questions, you can always ask me, I am always at your service, and I wish you a pleasant ride.

Black smoke from the exhaust pipe indicates that the mixture is too thick and the combustion is incomplete. Usually there are the following causes: blocked air filter or air intake line; insufficient cylinder pressure; The oil supply time is too late; Excessive oil supply or poor atomization of oil injection; The engine is overloaded.

Of course, in addition to the above factors, there are other factors, such as the poor oil return of the supercharger return pipe, the failure of the braking system sensor and other factors, which will also cause the phenomenon of black smoke in the engine. BMW 3 Series ( Check price |.)In the mid-range sedan market, it has always been used as a benchmark for handling performance. Armed with the M Package, the 3 Series is even more aggressive in terms of appearance and performance.

It's not like that's anything for BMW. Cars with this mark on their bodies are among the best performers in their respective model ranges. This time, BMW Brilliance has re-armed the exterior and interior of the 325i through a series of M packages, and the luxury model came into being.

If there is black smoke, you need to do the following troubleshooting work for the above conditions:

1. Check whether the choke is fully opened in time, and carry out high-speed maintenance if necessary;

2. After the flameout, look at the main nozzle from the carburetor mouth, if there is oil injection or dripping, the oil level of the float chamber is too high, and it should be adjusted to the specified range, and the main measuring hole should be tightened or replaced;

3. Check whether the air filter is blocked, and the air filter should be cleaned, dredged or replaced frequently.

When the engine is running, a large amount of white smoke is emitted from the exhaust pipe, and there are two situations:

1. The exhaust pipe discharges milky white oil mist. The main reason is that the fuel is not vaporized well, and it is discharged from the exhaust pipe without combustion, resulting in milky white smoke. It is more common in winter when the engine is starting because of the low temperature and poor fuel atomization.

It usually disappears after the engine is started as the engine temperature increases.

2. A large amount of water vapor and white smoke is discharged from the exhaust pipe, and there are water droplets at the exhaust pipe mouth. The main reason is that the cooling water enters the cylinder or the water vapor formed by the gasoline containing water.

Troubleshooting: 1. When the car parked in winter or rainy season starts for the first time, white smoke can often be seen. It doesn't matter, as soon as the engine temperature rises, the white smoke disappears and this condition does not need to be repaired.

If the exhaust pipe becomes black smoke after the engine temperature rises, it indicates that the cylinder pressure is too low or individual cylinders are not working, which should be checked and eliminated.

2. When the engine is running, a large amount of water vapor and white smoke are discharged from the exhaust pipe, and whether there is water in the fuel tank, whether the cylinder gasket is damaged, whether the cylinder block is cracked, and whether the cylinder liner sealing ring is good.
