What is the matter with the oil filter leakage when the Wuling Light car is driving, and the oil fil

Hello! Wuling Light leaks oil when the car is driving, and the oil filter does not leak when the car stops. Recommended check:

First, the oil is concerned about whether the core sealing ring is damaged or cracked. Whether the oil filter is tightened or not. Second, if the pressure of the oil pump is high, it will also cause oil leakage from the oil filter element.

You can use an oil pressure gauge to measure the pressure of the oil pump. If the oil pump pressure is too high, then it is possible that the oil pump pressure limiting valve is worn out, and the card is issued, resulting in excessive oil pressure and oil leakage from the oil filter. Hope it helps.

Hello, it should be that the sealing rubber ring is not good, when the engine oil flows strongly, the oil pressure is high and the temperature is high, and the rubber ring is not well sealed when heated, and the oil leaks. It is recommended that you go to the repair shop to replace the oil filter in time, I hope mine will be of some help to you. Have a nice ride!

The filter sealing ring or filter is broken, and there is pressure inside the starting car, and there is no pressure when the engine is turned off, so it does not leak.

First of all, you have to know the oil filter and find the oil filter in **? Then drain the oil, remove it directly with a professional tool, put on the new one, and tighten it. After changing to new oil. The air filter should also be replaced at the same time!

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.

The oil leakage at the filter element of Wuling Hongguang is that there is a foreign object on the contact surface between the base and the rubber ring, which damages the rubber ring; Or excessive knob deformation during installation will affect the sealing.

It is recommended to check the following from the following aspects:

1. It is recommended to check whether the oil ruler is firmly inserted (the ruler mouth can sometimes spray out the engine oil, which flows to the ring gear due to the movement of the car). Check if the exhaust pipe is blocked.

2 After removing the gearbox, check whether the oil seal cap under one shaft of the gearbox is well sealed, there is a possibility of gear oil leakage.

3 Check that the seal behind the valve chamber cover is good.

4. Check whether the oil induction plug is leaking.

5. Mainly crankshaft rear oil seal.

Then we have to see what is missing.

Generally, the oil seal before and after the crankshaft, the oil pan screw is not tightened, the oil induction plug is damaged, the camshaft oil seal, the valve chamber cover pad is damaged, the oil bottom pad is damaged, the oil filter is loose or damaged, and the oil dipstick is loose or lost.

Check the repairs yourself.

Look at the leakage of how to leak many parts of the line interface can be sealed and treated There are also places that are sealed with oil seals, such as crankshaft oil seals, camshaft oil seals, etc. There are also leaks caused by hanging to the oil pan or oil grid But no matter how it leaks As long as the leakage is obvious, we can't take it lightly The car does not have enough oil lubrication when the work will burn the tile After burning the tile, the engine can only be overhauled Not only costly and time-consuming, but also affects the use of the car, so it is recommended to find time to deal with the seal that should be replaced There is also the habit of using the car to develop the main instrument display, water temperature and oil alarm, can not be taken lightly.

No one knows what you're talking about.

First, check the exterior for oil leaks.

Pay special attention to whether there is oil leakage at the oil seals at the front and rear ends of the crankshaft. 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.

If there is oil leakage at the front and rear oil seals.

Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and other organic oil seepage, but can not find obvious oil leakage, should check the crankcase ventilation device, clean the crankcase ventilation duct, especially check whether the PCV valve due to carbon deposition and gelation stagnation caused by poor work. Poor ventilation of the crankcase is likely to lead to an increase in pressure in the crankcase, resulting in multiple oil leaks.

If the joints of the oil filter and some oil lines 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.

The main reasons are, first, is there too much oil in your oil pool? If you add too much oil, it will cause excessive pressure in the crankcase, and it will also cause organic oil in the intake tract and even the air filter.

Second, check whether the air filter is clogged or wet, if the air filter is clogged, it will cause excessive engine intake resistance, and there will be oil backflow in the engine inlet passage. The third valve oil seal is poorly sealed, which will also cause the oil to escape from the intake tract, and the air filter will also have organic oil, which needs to be measured by checking the oil consumption, and an oil change cycle (the interval mileage or time between two oil changes) If the amount of oil added is too large, then the valve needs to be checked.

Hello, the exhaust gas is too big, check the exhaust valve, and there is the engine string, which needs to overhaul the engine. I hope my answer can help you. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Check that the wastegas valve on the lower valve chamber cover is not broken. If this thing breaks, it will cause organic oil in the air cleaner.
