103 1 Chi Expert Hello My Buick LaCrosse 3 0 Burn Engine Oil Can you fix it

The repair shop can repair the engine oil burned, you need to overhaul the engine, replace the piston ring after disassembly, valve oil seal, check the cylinder wall, valve guide, valve valve, etc.

Most of the cars on the market now burn engine oil, and most of them are French cars, German cars, and BMW cars.

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, one is overhaul, and the second is PNF repair agent. 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 have to find out the reason for your burning oil, oil circuit blockage, carbon deposits, piston ring stagnation can be repaired with repair agent, there are riders who have repaired it with repair agent before, you can refer to it.

The oil itself has a certain amount of consumption, and this consumption is normal. If you consume too much, there is a 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.

First check whether there is oil leakage on the outside of the engine, check whether the crankcase ventilation valve is damaged if there is no oil leakage, and then check whether the valve oil seal is leaking, and only the piston ring can be replaced if there is no oil leakage. However, there is a high possibility of damage to the crankcase ventilation valve and leakage of the valve oil seal, so it is recommended that the local professional check it.

Hello, the engine burns oil because of the aging of the valve oil seal, the cylinder liner, and the piston piston ring are seriously worn.

Any engine will burn oil, because the engine needs lubrication, and the piston rings cannot scrape the oil so cleanly, and there will always be residue for lubrication or burning. This is called "oil consumption".

The size of the oil consumption can reflect the state of the engine.

The oil consumption is large and the power decreases, which is equivalent to a reminder that the engine needs to be overhauled and replaced, the cylinder liner piston and ring.

Brother drank too much! This is the Peugeot 308.
