The reason for the oiliness of the air filter

The air filter of car spare parts is for catching soot and dust and other substances except fat and oil. However, sometimes when you open the air filter, you notice that there is oil in it. One of the reasons is the lubrication of the moving parts of the cylinder head, such as its upper part, such as the camshaft, timing belt, etc. Therefore, one of the reasons for the mistake is opening the oil cap while the engine is running. This action causes the car oil to get hot and spray, which may burn your hand when you open it and make the surrounding area dirty.
To find out when the engine oil should be changed, measure the oil level and Make sure its percentage. Because this percentage should not be less than the minimum, then measure it again every thousand kilometers and if the percentage is correct, do it. After traveling a certain distance, you should remove the engine oil standard and reach the normal operating temperature, and you should pay attention to what happens and that the engine oil cap is well closed.

3 The main reasons for oil filter oil

1- PCV valve cracks or positive cartridge ventilation valve

The PCV valve is connected to the air intake chamber by a hose that is usually rubber and has an air valve inside. Usually, in most cars, this part is connected inside the engine in the upper part of the cylinder head cover. Right in the place where through the cylinder head, the pressure flows from the lower half of the engine and reaches the air intake.

2- The burnout of the piston rings

The second main reason you can check is the wear and tear of the piston rings. Engine oil leaks in the air filter chamber are caused by worn piston rings. These rings are installed on the outer edge of the pistons in the combustion chamber.

In the first stages of aging of the piston rings, excess oil turns into gas and causes excessive pressure inside the crankcase. that more oil goes through the PCV valve and finally reaches the air intake and causes the air filter to become greasy. Sometimes the obsolescence of these rings makes you think of changing the car.

3-The oil path

The last reason for blocking the oil path is due to carbon deposits, mud and mud. or sediment in the cartridge, which is the best solution for timely removal of motor oil, PVC valve and air filter.

علل خروج دود از درپوش روغن و آسیب های ناشی از آن

The emission of smoke from the oil cap is called side blowing, which means the entry or leakage of combustion materials and gases into the engine, that is, its exit through the piston rings into the oil channel and Cartier. It creates air and pressure inside the engine, so you may find that when you open the oil pan to the outside of the engine, it creates a big shock from the side, which can cause a lot of problems and damage to the car, including :

از دست دادن فشار که منجر به کمبود ظرفیت می شود.
باعث آلودگی روغن مخزن زانویی می شود.
گرم شدن و انبساط پیستون ها و ایجاد خط و خش در سطح پیستون ها و دیواره های سیلندر .

How to solve the problem of oil smoke?

First you should check the valves and the piston rings and if one of them is damaged or worn, replace them, and it is better to replace both parts, because the old parts are not able to withstand the pressure on them. . As a result, the part that was replaced.
