How much does it cost to repair Buick Yinglang burning engine oil and smoke

Hello, if the engine burns oil seriously, it is not serious to do a bell rest ** at about 2000 yuan. If the engine is overhauled, ** around 5000. I hope you are satisfied with me and have a good life for you.

Hello about 5000, it is recommended to repair in 4s, the accessories are guaranteed, the maintenance is also professional, I wish you a happy car.

This car first check whether there is oil in the intake pipe, if there is a valve chamber cover, it is good, if not, the engine will be repaired if all original parts are about 7000.

Most of the Buick Yinglang engine oil is caused by the piston ring being trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. The poor power and high fuel consumption of the engine are due to the fact that the oil participates in the combustion and forms more carbon deposits, which in turn aggravate the degree of oil burning and form a vicious circle.

Too much carbon deposits will clog the fuel injector, resulting in poor atomization and poor combustion. In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

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. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.

1. Reasons.

1.The flammable mixture is too thick. 2.There is too much oil in the engine fuel. 3.Poor piston ring or crankshaft oil seal sealing. 4.There is moisture in the fuel. 5.Bad spark plug 6The air filter is too dirty.

2. Fault diagnosis and elimination.

1.For the inspection and diagnosis of excessive concentration of combustible mixtures, the carburetor and air filter should be checked.

2.The blend does not compare with the blend of the oil, or the wrong grade of oil is used. If the oil mixture contains too much oil or the oil quality is poor, the oil of the flammable mixture cannot be completely burned, resulting in black smoke.

The above phenomenon can also occur in two-stroke engines with separate lubrication and oil pump misalignment and excessive oil supply. At this time, the oil pump should be checked and adjusted according to the regulations to ensure that the lubricating oil is supplied proportionally at different throttle openings.

3.Excessive wear or breakage in a four-stroke engine, as well as too much oil in the crankcase, can cause oil to string into the combustion chamber and cause excessive oil in the mixture. If the crankshaft oil seal of a two-stroke engine is broken, it will also cause the oil from the transmission to string into the crankcase and enter the combustion chamber with the mixture.

4.One of the reasons for the mixing of water in the fuel is that the fuel in the fuel tank itself contains water, so the fuel tank should be cleaned and the fuel should be replaced. Another reason is that the cylinder gasket of the water-cooled engine is broken, and cold water enters the cylinder.

If, in the absence of leakage, the water in the tank is consumed too quickly, and the exhaust smoke from the exhaust pipe is slightly white, this is mostly the reason and the head gasket should be replaced.

Black smoke from gasoline engines is rare, black smoke is mainly not completely burned fuel in the combustion chamber, in the case of high temperature and lack of oxygen, diesel can not be completely and fully combusted, so decomposition and aggregation to form soot, it is a small diameter of the aggregate.

Because this aggregate reacts much slower than gasified fuel, due to the high temperature and anoxic environment of the combustion chamber, it cannot be fully burned again and is discharged through the exhaust pipe, so black smoke is presented.

The direct consequence of this phenomenon is that the fuel consumption of diesel engines is very high, the power is reduced, and at the same time, a large amount of carbon deposits exist in the piston and piston ring valves. In severe cases, the piston rings will be jammed, the valve seal is not tight, and the air leakage will be accelerated, and at the same time, it will also accelerate the wear of parts, thereby reducing the service life of the engine, so this aspect should be paid special attention.
