My car doesn't smoke blue when it's cold, but it smokes blue when it's hot. The engine sound is obviously loud and the oil level drops rapidly. What is the reason and how to maintain it?

Blue smoke in cold car is the aging oil leakage of valve oil seal, and blue smoke in hot car can consider the piston ring sticking and burning oil when stepping on the accelerator deeply. The participation of engine oil in combustion will form more carbon deposits, which will further aggravate the combustion of engine oil and form a vicious circle. High viscosity engine oil can prolong the life of the engine, but this does not solve the fundamental problem. In the end, it will only lead to serious strain on the cylinder wall or even cylinder explosion and overhaul. So fix it as soon as possible.

Four reasons for burning engine oil.

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

The replacement cycle of antifreeze is too long or not replaced at all;

Third, the oil change cycle is too long;

Long-term or frequent short-distance driving.

One or all vehicles burning engine oil at the above four points must be accounted for.

High temperature stuck piston ring

In fact, the principle of piston ring sticking should start from the oil circuit. The bearing temperature of the oil is 1 10℃. The high temperature caused by the long-term uncleanness of the oil circuit makes the oil stay at 120℃ or higher for a long time, which makes the oil run out ahead of schedule, and the small holes of the oil ring are baked, crusted and stuck for a long time. One cylinder stuck is 5000 kilometers per liter of oil. Therefore, to solve the problem, we must start with the root oil circuit, which is the way to get rid of the root.

Fuel solution

Engine overhaul is the inertia thinking choice of many car owners. I always thought that overhaul would completely solve the problem of burning oil, but it is not like this.

First of all, there is no serious strain on the cylinder wall, so it is not necessary to disassemble the engine for overhaul, and the high maintenance cost, the oil cost for two running-in and the depreciation risk are not small burdens;

Secondly, because the assembly environment and technician level of the repair shop can't be compared with that of the main engine factory, it is difficult to return to the original factory standard after disassembling the engine, so some cars will have some unpredictable problems such as idling jitter, increased fuel consumption and weak refueling. Moreover, the new car can burn engine oil, so it is normal to clean the oil circuit from time to time and burn it after overhaul.

As long as there is no serious strain on the cylinder wall, there is no need to disassemble and repair it. After eliminating the related accessories, it is determined that the piston ring is stuck, which can be solved by Si Youpu's nondestructive repair method. When driving, let go of the piston ring to burn oil, and the effect is remarkable.
