Many car owners will be very flustered and anxious when they find their car leaking oil. If they don't find it for a long time, it will hurt your car and even cause some accidents. Today, we will sum up for you, which places are prone to oil leakage. Check these places frequently to prevent them from happening
First of all, oil leakage and oil leakage are two concepts. Car oil leakage is a normal phenomenon, oil leakage is a fault phenomenon, oil leakage is generally like this
Oil leakage from engine oil pan
This place is a place with high oil leakage frequency, and it is also a dangerous oil leakage location. The reason for oil leakage is that the required torque is not applied to the oil pan screw in strict accordance with the provisions in the maintenance instructions. No matter it is not tightened or the torque is too large, it may cause oil leakage.
If the amount of oil leakage is too large, the engine oil is easy to splash to the hot exhaust pipe in the process of driving, which is very likely to cause vehicle spontaneous combustion.
Valve cover leaking
This position is the most obvious oil leakage position in the engine compartment. The most common reason is the aging of valve cover gasket, resulting in poor sealing. Another reason is that the positive ventilation valve of the crankcase is blocked, which causes the pressure rise of the crankcase and releases the pressure from the valve cover pad or other weak places, resulting in oil leakage. Don't panic blindly when there is oil leakage. As long as the car owners usually pay attention to the car, they can find the oil leakage in time.
The leakage of the valve cover is due to the oil leaking out from the engine body, which will pollute the engine body, resulting in poor engine heat dissipation and reduced line insulation. If the oil leakage is more serious, the oil will be scattered on the auxiliary circuit around the engine, resulting in corrosion, aging and hardening of the insulation layer, affecting the normal use of the vehicle.
Brake oil leakage
As long as the leakage of brake oil is found, it will cause alarm, because it is related to driving safety, once the brake fails, the consequences will be unimaginable. How to find the brake oil leakage? First of all, we should observe the brake system frequently, and then we should pay attention to the changes of vehicle driving.
The brake stroke is obviously lengthened, some of which are caused by wear of brake skin, and some cases are caused by insufficient oil pressure caused by brake oil leakage. Note that once the brake oil leakage occurs most often in these places, the four wheels near the brake oil drain hole, brake oil pot, brake pedal, etc.
Oil leakage of shock absorber
Shock absorber is a vulnerable part. After tens of thousands of kilometers, there will be oil leakage. Oil leakage of shock absorber should be a problem that many car owners will encounter. In normal operation, the shock absorber also has the phenomenon of oil leakage, so first of all, we must distinguish whether there is real oil leakage.
Generally, the shock absorber needs to be replaced if the oil leaks to the position below the spring seat or the oil penetrates to the position below the spring support or drops of oil appear. If the shock absorber fails due to oil leakage, in addition to affecting the comfort of driving, it will also have a great impact on the handling and stability of the vehicle, and will also affect the normal work of other components in the suspension, and even damage its life.
Self inspection method:
Put the car on a flat place and press the body hard. The body can rebound no more than 2-3 times, which is normal. If there is vibration up and down and it can't stop soon, please go to the 4S store in time and ask a professional to carry out the test.
