The air filter of the modern car is hidden from the eyes in a large metal or plastic box. Since it is not in sight, the car owner checks his condition not as often as it should. And in vain, professionals recommend at least once a month to produce a visual inspection of the air filter. The condition of the air filter allows you to determine some faults. And if traces of oil have been discovered in the air filter - it can say, both about a serious malfunction and about small faults. We will tell here about the causes of oil from the air filter.

Air filter, traces of oil - a small problem

If you find traces of oil on your car air filter, do not panic.

The problem may be that lubricant gets through the hose by which crankcase gases are moving.

Remove the hose, and if there are oily deposits inside the hose, it is likely that lubricants in the filter are from the hose. Disconnect the hose on both sides, rinse it with water or not an aggressive detergent, install it for your previous place.

If after this procedure the filter will be clean, then the cause of filter contamination is set correctly.

And if after the work done, oil traces continue to appear on the filter - check the throttle.

If the throttle is strongly contaminated with nagar and outsiders, it does not allow the throttle to work properly.

The dirty throttle contributes to increasing the pressure of the discharge gases, the increased pressure squeezes the lubricant through the gland and the air filter remains oil trails.

The throttle must be cleaned of dirt.

If you are able to make such work on your own - do, but modern cars are equipped with an electronic throttle and work on cleaning the throttle is difficult for such cars, it is better to turn to professionals. And if the throttle is clean, and oil stains continue to appear on the air filter, the reason is that the combustion products are deposited on the main oil reflector.

It means that it is necessary to check the oil pulp (the oil collector).

Remove the engine oil from the engine and inspect it.

The oil retardant is a sufficiently soft detail, it is able to absorb the liquid and stop its current.

In the case when the little expresser is badly polluted and cannot be cleaned, it needs to be replaced with a new one.

You can install an additional oil reflector under the cover of the block head, but if there is no necessary part at hand, and the oil production must be stopped, try to install a conventional metal sponge for the dishes for a while and in the future, set the desired part.

If all your attempts to stop the appearance of oil in the filter were not crowned with success, try cleaning the filter itself.

The air filter is capable of muddled very little to miss air, the engine is not enough and it begins to pull the air from any sources, it can cause the oil to move the oil in the intake path.

And so, it would not seem like an important detail as an air filter, an untimely replacement, may further create a greater problem.

In order not to create this problem, replace the air filter on time.

But if you made the above work and changed the air filter to the new one, and then the car passed about 500 km. And on the filter again there were traces of oil, most likely, you have a serious problem.

Air filter, air filter oil traces - a signal about serious problems

If the reason for the appearance of oil in the air filter is assumed to more serious problems, it is necessary to check compression inside the engine cylinders.

Checking on a preheated engine.

It is necessary to make reconciliation of performance of various cylinders with each other.

If the indicators differ more than 1 atm, then the engine has occurred or dismissed, i.e. There was a wear of the oil-clearing rings.

It is necessary to check the condition of the valves and their gaps.

The violated operation of the intake and graduation system, can also provoke oil entering the air filter.

If the above work has not confirmed the cause of oil in the air filter, check the seals that seal the lubricant in the engine crankcase.

The worniness of the seals can be the cause of air filter contamination with oil.

Well, and if, having done all the work, you did not find the reason, you will have to appeal to professionals.

A hundred will make diagnostics, accurate diagnostics will allow you to put your engine in order.

Air filter, air filter oil traces can lead to overhaul

If the engine engine has received serious wear, it is overhauled.

Such a repair involves the replacement of oil-dialing rings, glands and other seals, which can cause oil to enter the air filter.

In particularly difficult cases, it replaces the pistons and valves.

And if financial difficulties do not allow you to make overhaul, practices offer a way to temporarily postpone overhaul, but provided that the car runs less than 500 km.

The overpowering of the overhaul must be made in the following order:

- Cut from the fitting hose of the supply of crankcase gases;

-The point the fitting and make sure;

- Strong under the engine a long hose and perform the ventilation of the crankcase through it. But, the movement of the car in winter with an elongated hose will lead to a bad heating of the throttle assembly, so the best solution to maintain engine overhaul.

Keep track of engine service deadlines, change all consumables according to the deadlines, check the color of the oil after the drain.

If the exhaust oil is completely black or have solid inclusions - do the engine diagnostics.
