What should I do if Buick LaCrosse burns engine oil, and I can only overhaul it?

The main reason for burning engine oilIn two aspects, one is that there is a problem with the accessories, the waste valve, the valve oil 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. 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.

Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

SolutionThere are two ways to solve the problem of burning engine oil, in addition to overhaul, which is PNF repair agent. If it is not a serious cylinder pull, engine damage does not need to be overhauled. Depending on your situation, clean the oil circuit with a repair agent, and you should be fine once the piston is released.

There have been riders who have repaired it with a repair agent before, you can refer to it.

What should I do if Buick LaCrosse burns engine oil, and I can only overhaul it? If the burning of engine oil is not very serious, you can add oil additives to solve it, if it is very serious, it can only be overhauled.

When you go to a 4S shop, you will generally be called to overhaul, but there is no need, and overhaul is too troublesome, not to mention the high cost and time consumption. My car also burns engine oil, all of which are continued with engine oil, the original factory used before is not very good and replaced with imported German GT magic red engine oil, four types of PAO base oil, the quality is very good, will not produce so much carbon deposits, the power of the engine has little impact, the liquid molybdenum component in the engine oil can also reduce the power wear and tear consumption of the engine, improve the power, and there is no problem with the normal operation of the car.

If the vehicle burns oil for maintenance, if it is followed, the maintenance of the normal minimum parts will cost about 3,000 to 4,000 yuan [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

It needs to be dismantled and inspected before the maintenance can be determined**, about 5000 yuan or more. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

You need to disassemble the engine to see what parts don't work. **Not necessarily broken down to know. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, you look at whether the oil is leaking if there is no overhaul about 8000, I hope it will help you, if you still have questions, please ask.

The solution of Buick LaCrosse to burn engine oil is as follows: 1. Check the exhaust pipe: check whether the exhaust pipe is still smooth.

If it is not smooth, it should be cleaned or replaced in time. After driving for a while, see if the oil is missing and if the exhaust pipe is emitting blue smoke. 2. Measure cylinder pressure:

If the cylinder pressure is normal, it should be the aging and damage of the valve oil seal, which causes the engine oil to be burned and the valve oil seal is replaced. 3. Check the pressure cylinder: If the cylinder pressure is single, multiple or lower than the normal value, then only uncover the grinding cylinder head to check whether the cylinder gasket is flushed, the bore wear, the piston wear, the elasticity of the piston ring, etc.

If you just flush the oil duct, you can replace the cylinder gasket. If the bore and piston wear are too large, it is recommended to overhaul and replace all cylinder liners, pistons, and piston rings. If the bore is not worn out much, the piston and piston ring can be replaced.

If it is the reason for the piston rings, you can negotiate the shooting by replacing all the piston rings.

There is a high probability that the piston is stuck and causes the engine oil to burn.

Carbon deposits will be deposited in the grooves of the piston, causing the piston rings to stick together, which causes the piston rings to be stuck and cannot be completely sealed, and the "sticky" piston rings greatly reduce the ability to scrape oil sealing, in addition, the oil sludge will also block the oil return hole, and the oil can not be refluxed normally, resulting in an increase in oil consumption. Carbon build-up can exacerbate wear between the piston and cylinder walls, resulting in too much clearance and oil entering the combustion chamber. Valve oil seal corrosion aging, resulting in poor sealing, valve oil seal can be said to be the most vulnerable parts in the engine to age, basically more than 100,000 kilometers of cars, have this problem.

The oil seals of the front and rear crankshafts are aging, and the oil seals of the front and rear crankshafts are in contact with the oil in a large area and continuously, and the impurities of the oil and the continuous temperature changes in the engine make the sealing effect gradually weaken, resulting in oil leakage or oil leakage.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel is indispensable in the combustion process to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all of which are directly or indirectly related to the formation of carbon deposits, so keeping the fuel circuit clean has a lot of help to prevent burning oil, of course, this needs to rely on high-quality (PNF) fuel additives.

Buick burning engine oil is a very common phenomenon, in fact, no matter what car type of engine has a certain amount of oil consumption, not that you think that it is not burning, but the performance is not obvious, but too much consumption is burning engine oil. As long as there is no serious strain on the cylinder wall, there is no need for major repair.

Most of the engine oil is caused by the trapped carbon of the live lead cover plug ring. 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 oil circuit is not clear for a long time to stimulate the high temperature caused by good cleaning, so that the oil is 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. 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. Especially containedThe patent technology of the PNF is popularNon-destructive repair products, has completely gotten rid of the technical shackles of the operation of the auto repair shop, without removing a screw, the owner can operate it himself, and the piston ring is repaired and released during driving, and the effect is remarkable.

Causes and solutions: 1Check that the exhaust pipe is not smooth.

If not, clean or replace. Drive for a while longer to see if the oil is missing and if there is still blue smoke coming from the exhaust pipe. 2.

Measure the cylinder pressure, the cylinder pressure is normal: it should be the burning of the engine oil caused by the aging and damage of the valve oil seal, and replace the valve oil seal. It is recommended to replace all oil seals.

3.If the cylinder pressure is single, multi-cylinder or all lower than the normal value, then only the cylinder head is lifted to check whether the cylinder gasket is flushed, the bore wear, the piston wear, the elasticity of the piston ring, etc. If it's just a flush line, just replace the gasket.

If the bore and piston wear are too large, it is recommended to replace all cylinder liners (cylinders), pistons, and piston rings. If the bore is not worn much, the piston and piston ring can be replaced. If it is the piston ring reason, then just replace all the piston rings.

First of all, check whether the exhaust pipe is still unobstructed. If it is not smooth, it should be cleaned or replaced in time. After driving for a while, see if the oil is missing and if the exhaust pipe is emitting blue smoke.
