Wuling Light 6389 engine leaked oil

There are two basic scenarios for the causes of oil leakage in a car engine:

1. Oil leakage from automobile engine. There are relatively clear oil stains on the surface of the car engine shell, if the oil stains are cleaned up at this time, and the oil stains on the shell are found soon after, and even some serious gasoline is still falling like water droplets, this problem should be sent to the car for maintenance as soon as possible.

2. Oil leakage from automobile engines. There is only a small amount of oil stains in the engine shell, which means that the engine oil leakage is not particularly serious, and the oil leakage at this time is not obvious and small, and it has little impact on the engine at this time.

The most direct and effective way is to change the sealing ring, the urban roads are congested, and the stop-and-go needs to be constantly shifted; Nowadays, there are more and more gears in the car, resulting in more gear shifts, greater working pressure in the gearbox, and higher temperatures, which accelerates the aging and deformation of the rubber at the gearbox seal.

There is also a small part of it because the transmission oil is added too much, which increases the resistance of the transmission gears. When the gears of the transmission are strained, problems in the box will also increase, which can lead to loose oil seals and eventually oil leaks. Therefore, it is necessary to refuel according to the maintenance manual.

Sudden large-scale oil leakage, such as yesterday was fine, today suddenly found that there is a large pool of oil on the ground, often caused by the oil pan bottom deformation, rupture or the filter is not tightened. When such a problem occurs, you should immediately check the oil balance and go to the repair shop to check it as soon as possible.

Extended Information: Causes of Engine Oil Leaks:

1. Engine oil leakage caused by poor sealing of valve chamber cover gasket, oil radiator, oil filter, distributor housing bearing hole, rocker arm chamber cover, cam bearing rear cover and engine bracket plate deformation.

2. When the front and rear oil seals of the crankshaft and the oil pan liner of the automobile are damaged to varying degrees, it will also lead to engine oil leakage.

3. If the timing gear cover gasket of the car is not properly operated during installation, or if it is damaged to a certain extent, the screws are loose and leaking.

Handling of engine oil leaks and hazards:

1. The solutions taken for different models are also different, some engine oil leaks do not need to remove the cylinder block, but some parts of the oil leakage cylinder block need to be removed. It is best to deal with it according to the specific situation of the car.

2. The engine oil leakage of the car is not a big fault, and we do not need to repair the car for the time being. However, if there is an oil leak in the engine, it needs to be carefully inspected.

3. The engine oil leakage of the car will bring certain damage, the most important of which is to cause the car to lose a lot of oil, and there is a waste of it. If it is severe, it may cause damage to the engine due to insufficient oil.

It is possible that the pad is broken, or there is a large compression in the engine.

Oil leakage from the engine cover of Wuling Light should be the cause of the aging and damage of the cylinder head gasket:

1. Check whether there is oil leakage on the outside of the first chain, and pay special attention to whether there is oil leakage at the front end of the crankshaft and the oil seal at the rear end. Oil leakage at the front end of the crankshaft can be caused by broken or damaged oil seals at the front end of the crankshaft, aging or worn contact surfaces between the crankshaft pulley and the oil seal. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft.

In addition, attention should be paid to whether the rear end of the camshaft oil seal is leaking. The oil seal should be replaced in time if it is aging, broken and leaking. In addition, it is necessary to check whether there is leakage in each part of the engine lubrication system;

2. If there is oil leakage at the front and rear oil seals, or even organic oil seeping out from the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan liners, etc., but no obvious oil leakage can be found, the crankcase ventilation device should be checked, and the crankcase general air duct should be cleaned, especially to check whether the PCV valve is working poorly due to carbon deposition and gelatinization. If the crankcase is poorly ventilated, it is likely to cause the pressure in the crankcase to rise, resulting in multiple oil leaks;

3. If the joints of the oil filter and some oil pipelines are still leaking after being tightened, attention should be paid to check whether the oil pressure is too high and whether the oil pressure limiting valve is not working well.

Summary. Hello, I am happy to serve you The key to this situation is that the mixture of gas in the engine is too concentrated, which affects the insufficient fuel combustion, which is also the key manifestation of the engine failure problem, and there are many reasons for such a failure problem, which need to be investigated one by one. When the air filter used in the vehicle is too dirty, the ignition state of the spark plug is poor, and the ignition coil is faulty, etc., it will basically lead to black smoke from the engine exhaust.

Wuling Light 6400 Type 465 engine emits black smoke waste gasoline, what is the reason.

Hello, I am a car for more than ten years, and I am happy to serve you. I have been engaged in the automobile-related industry for more than ten years, and I have sufficient professional knowledge of Hu Zhi, so please feel free to ask or make a noise. Below I will manually your question, please wait a moment.

Hello, I am happy to serve you The key to this situation is that the mixture in the engine is too concentrated, which affects the insufficient combustion of fuel, and the phenomenon of such a trillion rise is also the key manifestation of the engine failure problem, and there are many reasons for such a failure problem, which needs to be investigated one by one. When the air filter used in the vehicle is too dirty, the ignition state of the spark plug is poor, and the ignition coil is faulty, etc., it will basically lead to black smoke from the engine exhaust.

The main reason for burning engine oil is that the combustion state is not right, the combustion speed is slow, and too much heat is transferred to the cylinder wall, causing part of the engine oil to volatilize at high temperatures. The easiest solution is to use American multi-way tablets, according to the survey, all cars with this product have solved the problem of burning engine oil.

There are two ways to solve the problem of burning engine oil

Overhaul. PNF restoratives.

Benefits of this one: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.

Not a major overhaul to solve the problem of burning engine oil.

All kinds of models repair the record of burning engine oil.

Most of the oil burning in Wuling Light 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.
