What is the cause of oil leakage under the car after parking

Causes and solutions for oil leakage under the car: If it is just oil stains and oil stains, you can continue to use it, and you can wait for the next maintenance to do the repair. If it is an obvious oil droplet, no matter which component is leaking, it needs to be overhauled in time and the seal or fitting needs to be replaced.

Take a closer look, if there are obvious oil droplets, it is recommended to go to the store for maintenance in time, and the failure during the warranty period can be claimed for replacement of new parts.

In the use of vehicles, there are often oil leakage faults, which not only directly affect the technical performance of the car, resulting in the waste of lubricating oil and fuel, and the consumption of power, but also affect the cleanliness of the car and cause environmental pollution. Due to oil leakage and reduction of lubricating oil inside the machine, the parts are poorly lubricated and cooled insufficiently, which will cause early damage to the parts and even leave hidden dangers of accidents. Therefore, now let's analyze the main causes of oil leakage in automobiles and analyze the hidden dangers of oil leakage in automobiles.

The main causes of oil leakage under a car are:

1. The quality, material or process of the product (accessories) is not good; There are problems with the structural design.

2. The assembly speed is improper, the mating surface is not clean, the liner is damaged, displaced or not installed according to the operating procedures.

3. The work failure is caused by uneven tightening force of the fastening nut, broken sliding wire or loose falling off.

4. After long-term use, the sealing material wears too much, and the aging deteriorates, deformation and fails.

5. Adding too much lubricating oil, the oil level is too high or adding the wrong oil.

6. The joint surface of parts (side covers, thin-walled parts) is deflected and deformed, and the shell is damaged, so that the lubricating oil seeps out.

7. After the breather plug and check valve are blocked, due to the effect of the air pressure difference between the inside and outside of the box, it will often cause oil leakage in the weak part of the seal.

There are several possibilities.

1. The oil filter is not installed well and leaks oil;

2. The oil bottom screw on the oil pan is loose;

3. Damage to the front and rear oil seals of the crankshaft of the car will also cause oil leakage.

It is recommended to go to the repair place to hang it up to check where the leakage is, and repair it depending on the situation.

I missed a lot of it first, and then check whether the oil in the car is enough! If you can drive to a professional maintenance place and call the maintenance personnel to check whether there is any leakage!

First look at your engine to see if there is a leak of oil marks, and then see if your oil dipstick is short of oil, if the engine is not leaking, the dipstick is not short of oil, it may be that you are wrong, it is another car leaking oil, you just stopped on it.

If you don't know how to repair, don't solve it without authorization, find a repairman to ask.

Check if there is a real problem with the part.

Many parts of the car must be moistened with automobile oil, and some machinery and equipment must be boosted by hydraulic oil. Recently, a car buyer said that he found an oil leak under the car after the second day of parking, but the details of the oil leak are not clear. In fact, oil pan cracking, oil leakage in the steering system, untimely installation of oil filters, and oil leakage from shock absorbers can all cause organic oil under the car.

What happens when there is an oil leak under the car after parking?

1. Oil pan cracking. If the chassis of the car has been subjected to a lot of impact before, then it is necessary to check the oil pan for cracks. Cracking of the oil pan will cause water leakage in the car oil;

2. Oil leakage in the steering system of the car. If the silicone sealing ring on the power steering pump is embrittle, then the power steering oil will leak out, and the power steering system software will be completely ineffective, and the steering wheel of the car will become significantly heavier and heavier;

3. The oil filter is not installed in time. Every time the car oil circulation system is based on the oil filter, if the oil filter is not installed properly, there is no doubt that the car oil will leak;

4. Oil leakage from shock absorbers. There is lubricant inside the shock absorber, and if the gasket inside the shock absorber is damaged, it will also cause oil to flow at the bottom of the car.

How to solve the gray-black oil on the road surface in front?

1. If the leakage part is just under the oil pan, you don't need to run the car at this time. The car should be immediately notified to come to the rescue, which requires going to the car 4S shop to dismantle the engine oil pan of the car;

2. If you find that the steering wheel of the car is becoming more and more unusually heavy and leaks oil with the chassis during the driving process, it means that there is something wrong with the steering power system software. In this case, the power steering pump must be dismantled and replaced to solve the difficulty;

3. Reinstall the oil filter. Open the hood of your car, check the oil filter for oil leaks, and reinstall the oil filter if you can.

How to prevent water leakage in the car's hydraulic oil?

1. It is necessary to pay attention to the real-time road conditions to prevent collisions into the chassis of the car. If the car drags the bottom, it is very easy to cause the oil pan to crack, which is very harmful to the car engine;

2. Regularly maintain the silicone sealing ring of each part of the parts. The silicone sealing ring will gradually embrittle after heating, and the possibility of oil leakage due to the silicone ring in older cars is relatively large;

3. During maintenance, the screw should be tightened in accordance with the specification of the torque, and the torque is too high, resulting in oil leakage due to the deviation of the screw, which is very loose and cannot be tightened and the gasket can not be tightened, and then oil leakage occurs.
