Crashing oil filter symptoms. Causes and signs of clogging of the transmission filter

The oil that we pour into the engine is wear out in itself, even if the car is calm in the garage - it is oxidized. Moreover, oil wear is inevitable with the active operation of the engine under serious loads. One of the large tests for the engine can be oil starvation - how to avoid it, signs and consequences, and how to determine the oil starvation, find out right now.

What is the oil starvation of the engine?

Due to the insufficient amount of aluminum lubrication almost melted

The lack of lubricant in some nodes in certain modes of engine operation is theoretically called oily starvation.

For obvious reasons, in the absence of lubricant in rubbing nodes, they instantly fail. Danger of oil starvation The motor is that it may occur instantly and almost completely destroy the main engine nodes:

• crankshaft,
• camshaft
• gas distribution mechanism,
• cylinder-piston group,
• other vital and expensive nodes and aggregates.

Torn insert camshaft (due to insufficient lubrication)

In the same way!

In a flat place, oil starvation does not occur And as a rule, all the wines in the breakdown lies only on the owner of the car or motorists who made repairs. As is known, the oil is in the crankcase in the amount needed for lubricant and is supplied to the system with an oil pump. In the event that the oil can not get to some rubbing nodes, oil starvation occurs. The reasons for this may be mass.

How to determine oil starvation

It immediately it was clear that the engine was "hungry oil"

Initially, the determination of the oil starvation of the engine, since the spectrum of symptoms is wide enough - from the drop in engine power, before overheating, outsiders and knocks. All this indicates the wear of certain, characteristic of each engine of the nodes. For example, in the most common upropment gasoline engines often occurs accelerated wear and increased noise when operating a gas distribution mechanism.

Effects

The consequences can be the most different - the camshaft is jammed, the breakdown of the camshaft, the flap of valve, the destruction of the valve rocker, the turning of the crankshaft liners, the rings in the sleeve right up to the destruction of the pistons.

In addition, there may be oil-chained rings, which will lead to even greater overflow of oil and engine jamming. SIZY thick smoke from exhaust pipe Just says about the malfunction of the scale rings and high oil consumption.

Causes of oil starvation

Engine operation in oil starvation mode Almost in all cases is accompanied by an increased temperature, which you need to pay attention to. In addition, the oil pressure in the system can be either very low (what will say the inspection lamp of the oil pressure on the instrument panel) or unstable. All this may be caused by such reasons:

1. Insufficient oil level in the pallet . Lubricants simply lacks for the processing of all bearings of sliding, the oil film is absent, the details work almost dry. That is why at least once a week, and with active operation more often. In addition, it is necessary to closely monitor the height of the oil and, if necessary, take measures to eliminate the leaks.

   

   Property of oil in the engine (from above the analog, from the bottom of the original). Not the right testimony of the probe can not specify the car owner about insufficient level Lubricants.

2. Using the oil inappropriate . This is a very important point, because, for example, oil 5W-30 when used in summer it may not give the necessary viscosity, the engine lubricant will be insufficient, pressure when high temperatures It may critically fall. To avoid this, you need to adhere to the recommendations of the car manufacturer in the choice of engine oils.
3. The grid of the oil worker is scored . The oil pump is not able to overcome the resistance of the scored mesh, so the oil cannot be served in necessary quantity and under the desired pressure to all nodes. It also concerns clogged oil pipelines. An ideal way out of this position is a disassembly and mechanical cleaning of channels and an oil worker, wash products can only make worse.

4. Irregular or unreasonable replacement Oils and filters . Each oil brand has its own resource that needs to be strictly observed. Lubrication during operation loses most lubricating properties and by the end of the service life can be almost completely oxidized and losing viscosity.

5. Wear of oil rings and increased flow Oil . Wear masonry CapsThe crankshaft glands will also lead to high oil consumption.
6. Poor-quality engine assembly after repair . The competent motorist will never use the sealant where a fairly simple laying is that excessive sealant is asleep not only outside, but also inside the oil canals, over time clogging them.
7. Failure, clogging of the reduction valve of the lubrication system.
8. Clogging of the oil filter.

conclusions

As we can see, the reasons for oil starvation can be plentious, and in order to prevent breakage, it is simply necessary to check the oil level from time to time and comply with the regulation of its replacement, to eliminate leaks in time. Then the engine will last long and without expensive repairs. High quality oil and good roads!

Oil pump faults will inevitably lead to violations in the operation of the engine lubrication system internal combustion. It serves to provide pressure in the oil supply system. Symptoms of faults and interruptions The device is talking about serious problems that require immediate elimination.

Basic signs of oil pump malfunction

The car lubrication system ensures the stable and durable operation of the main engine nodes. The engine contains many details, which in the process of work are experiencing a strong effect of friction and without constant lubrication are rapidly wear out.

Many motorists are interested in the question - how to find out the faulty oil pump? With insufficient oil supply, the so-called "oil starvation" is formed. It can lead to an engine failure, resulting in a complex and expensive major overhaul of the force aggregate.

One of the first signs that the device for pumping oil is damaged, the light bulb will become on the instrument panel. If this happened, you should check the pressure in the oil supply system, as well as pay attention to the oil consumption.

1. Reduced oil pressure in the system.
2. Noticeable increase in oil consumption.

In the case when the pressure is reduced in the device, it is impossible to use the car to establish the cause of the problem and repair the machine.

There are several main causes of violations in the system. Here is some of them.

Causes of Oil Pump Fault

• drop in the oil level in the engine crankcase;
• damage to the pressure controls;
• the use of low-quality oil;
• using unsuitable for this car oils;
• failure of lubricant or safety valves;
• pollution of oil filter;
• crashing oil worker and blockage in the pump housing.

The clogging may be a consequence of a contaminated engine crankcase. To eliminate this trouble, it is enough to remove the carter (pre-drained the oil) and clean the pallet from the dirt.

Disorders in the operation of the oil pump can manifest itself in the form of various problems. It is possible to determine them during diagnostics. Maintenance possible problems The mechanism is listed below.

Oil pump faults:

• damage to the gasket;
• clogging of the oil filter;
• the filter is fixed unreliable;
• increased depreciation of the main parts;
• the failure of the reducing valve.

The oil pump in the car has a sufficiently long service life and breaks infrequently. Most often, the breakdowns lead improper operation car Engine, low-quality repair or use of poor-quality oil. Reduced oil pressure and growth of its consumption are the basic signs of the oil pump malfunction, after the detection of which should be diagnosed with the system and eliminate the cause of the breakage.

Oil pressure can be low for several reasons that do not require engine repair. These include the following:

Low oil

Checking the oil level is necessary before making a decision on the repair of the engine. When the oil level is low, the oil pump tube of the oil pump is difficult to dial enough oil to maintain the desired pressure in the system. Low oil pressure under these conditions is a small evil compared to those damage that can cause low oil pressure. Probably, the best prophylactic measure in this case will be checking the oil level in the engine at least once a week and topping the oil as needed.

Crashing oil filter

The simplest or most obvious cause of low oil pressure is to clog the oil filter. Unfortunately, it is not possible to definitely say that this is usually the result of inattention or error. If the oil has not been replaced during the time when the engine has suffered from low oil pressure, then you need to replace the oil and filter.

Liquid or diluted oil

The idea of \u200b\u200bacquiring an oil that is too liquid (i.e. with low viscosity), rather stupid. If you use the oil that was purchased in order to lubricate the automotive engine, it is almost impossible to purchase an oil that in itself will cause low oil pressure. Some people may not agree with the statement that use dense oil With high viscosity there will be a reason for increasing oil pressure. Often it happens fair. However, if the oil pump and bearings are in good conditionEven low viscosity oil will be able to provide the desired oil pressure.

Another thing is diluted oil. Oil becomes diluted with several paths. Perhaps the most common way is described below. When the engine works, especially after starting, some exhaust gases breaks through piston rings And enters the engine crankcase. These gases contain a certain number of unburned gasoline. Lost gasoline diluted motor oil. This dissolved oil can cause low oil pressure. But there may be an even more critical phenomenon, which is that unlawful gasoline in combination with moisture in the crankcase can form an acid that can damage the bearings and their surfaces for quite a long time before the low pressure of oil caused by its dilution, Hold the engine.

Another way: Motor oil can become diluted due to fluid (coolant). If the cylinder head laying begins to proceed or if the head or cylinder block cracks, the coolant can flow into the combustion chamber and / or in the engine crankcase and dilute the engine oil.

Although low pressure due to dilution can be determined by simply replacing the oil, the question is as follows: does the engine need a serious repair due to a malfunction caused by dilute motor oil? Another question is like this: how much damage was the result of dilution? Simple oil replacement can increase its pressure, but the engine can be damaged, and these damage must be eliminated before the catastrophic consequences will occur.

Reduction valve of the oil pump led in the open position

All engines are equipped with a reduction valve of oil pressure in the oil pump. The task of the valve is to limit the oil pressure in the areas that prevent the oil filter conversion into a fragmentation grenade. Occasionally, the reduction valve is in the open position, allowing oil to oil pump and return back to the oil pan. This malfunction is very difficult to determine and it may be necessary to completely sort out the engine.

If the time is not a critical parameter, remove the oil pan and install a new oil pump, although it is possible to repair the repaired valve, there is no great point to remove the oil pan and make the repair "just in case."

To reduce the friction between the car in contact with each other, the oil is poured into the cavity of the motor. However, as it is polluted, it loses its beneficial features. In order to extend the life of its operation, the oil filter is used in the lubrication system - the item, which also needs a periodic replacement.

How the oil filter is arranged and why change it

Many modern filters have an unbalanced design.

The device of the modern oil filter is quite simple

Oil filters are easy enough - they consist of the following elements:

1. Case made of metal.
2. Filtering element.
3. Reverse (or controversy) valve.
4. Corrective valve. It is installed at the entrance. At the moment when the engine is launched, the valve opens. In this position it is throughout the entire time of operation of the motor. After stopping the motor, the valve is closed, thanks to which the oil is held in the filter.
5. Bypass valve. It triggers in cases where the oil does not manage to pass through the cavity of the cleansing element freely.

Problems with cleansing happen if:

1. The filter is strongly polluted.
2. The viscosity indicator of the oil is increased due to the low temperature of the ambient air.

Whether you need to change

As a rule, the filter element and engine oil change simultaneously.The frequency of this procedure is influenced by several factors:

1. What basis was oil.
2. In what conditions the car is operating. With intense urban motion, the replacement procedure will have to be carried out more often - such a ride is conjugate with constant braking and accelerations. Also, it should be done in the case of the car in the mode of increased engine loads.

The filter replacement must be performed when overhaul Motor. Do it, as a rule, after run 150-250 thousand km.

Taking into account the foundation on which oil was made, it is recommended to observe such frequency:

1. Oil having a mineral base must be changed after the car "ran" is 7,000 km.
2. On the semi-centtetic engine can work without prejudice to about 10,000 km.
3. Synthetic oil qualitatively performs its functions for 15,000 km.

Filters also change depending on the mileage of the machine.

When the filter is stuck, the car engine starts overheating strongly

If a new oil is poured into the engine, the filter replacement should be carried out at mandatory. After all, after passing the car 10,000 km (on the semi-synthetic), this item is contaminated to such an extent that the bypass valve is opening and the oil begins to enter the engine with crude.

Sometimes the filter has to be changed separately from the oil. This necessity arises if the filter element has failed due to the factory marriage or mechanical damage.

How to find out that the car filter has been hammered and you need to change it: symptoms and signs

Check if the filter is scored, the ordinary driver will most likely fail. But there are several signs that indicate the failure of replacement:

1. The engine begins to overheat. This is because there is an insufficient amount of oil. The temperature of 80-100 ° C is considered normal for a working motor.
2. Fuel consumption increases markedly.
3. Motor operation becomes uneven.
4. There is a drop in the power of the car, the dynamic indicator is reduced.

Can I wash the crab oil filter

Filter flushing is a very time-consuming operation that requires high time costs. To begin with, it should be found out which material is used as a filter element. There are many options, and each of them has its own reaction to kerosene, oil and gasoline.
Before washing, the clean part of the device must be closed using special plugs and plugs. It is necessary to make it so that foreign substances do not fall into the filter cavity.

Replace will be much easier and cheaper.

What is different and what oil filters are

Currently produced oil filters of several types. They are:

• full-flow;
• partial accounting;
• combined.

Difference between types oil filters lies in the following:

1. The main oil flow heading from the pump in the full-flow filter is passed through the filter elements. So, the units and units of the motor are made fully purified oil. The fundamental role in this design belongs to the bypass valve regulating the pressure level in the motor.
2. Cleaning the oil from impurities when using a partial filter requires more time. There are two contours in the details: in the first oil freely circulates, passing from the pump to rubbing parts, in the second it is passed through the cavity of the filter element. Cleaning quality is higher than when using a full-flow filter.
3. In the combined version, both filtering methods are combined. The oil is cleaned even more carefully.

For carburetor engines Internal combustion can use a filter that transmits abrasive particles is less than 20-40 microns. To ensure uninterrupted work injector motorIt will have to acquire the item, the bandwidth of which does not exceed 10-15 μm.

How does oil cleaning in a diesel engine

W. diesel engine Cleaning requirements for oil even higher, and therefore apply filters on it used on gasoline engines, unacceptable. Oil up to the moment of entering the diesel passel, three stages of cleaning are passing:

• preliminary, which is still in the fuel tank;
• coarse
• thin.

Each of the stages are involved different types filters.

Reasons to buy original filters of well-known firms and the consequences of the use of low-quality fakes

Choosing between original and fake devices, it should always be remembered that manufacturers of non-original products are primarily interested in reduced costs. The level of quality is worth them at best in the second place.
Arguments in favor of using original filters:

1. They are fully compatible with a specific car.
2. They are distinguished by high quality manufacturing.
3. You can not worry about the loss of warranty.

Reasons forcing drivers to use non-original filters:

1. High cost of the original model.
2. Long expectation of the supply of the original product.

Using a bad filter will allow you to save money at some stage. But in the end it turns out even more expenses. Poor purified oil will definitely lead to serious trouble with the car engine.

Abrasive particles fall into the engine with uncleaned oil. The friction coefficient is increased between the various moving components of the motor. The consequence of this engine is becoming overheating, which can lead to a jam.

Famous manufacturers: who has the highest rating

One of the most famous manufacturers of oil filters is Bosch. Products of this brand invariably differ with the highest quality. A variety of filters manufactured is such that it is possible to choose the item depending on the year of the machine. The reverse side of the high quality and wide range is "biting" price.

Bosch filters are distinguished by high quality and are presented in a wide range.

Filtron oil filters are produced in Poland. They can be used both on cars of domestic production and in foreign cars. They are reliable and durable. In addition, many cleaners are suitable for them.

FILTRON filters can be used as on domestic carsand in foreign cars

Another one famous brand is goodwill. The filters of this company can be distinguished by a special system producing cleaning from small and large particles. A large range allows you to choose the item for almost any car.

GOODWILL filters cleanse oil from small and large particles

The quality of filters listed above manufacturers is on very high level. The differences of them are usually concluded in the brands of cars for which they are intended.

Preparatory work: what to do with the engine before replacing

Before replacing, preparatory work is carried out:

1. Machine poured on watching pit garage or overpass.
2. Worked oil is drained from the engine.
3. To avoid contamination of the surrounding space, the capacitance of the corresponding size is placed under the drain hole in the pan.

How to install a new filter using a special key

1. Turn the plug in the pallet hole. In order for the oil to go faster, the engine opens the neck through which it is poured.
2. After the oil is fully stroke, unscrew the filter. For this apply a special key. With its absence, an ordinary score is used quite large, with which the filter housing is pierced. A powerful lever is obtained, with which you can delete your element spent. Shuffle must be closed closer to the lid, otherwise you can damage the fitting on which the oil filter is mounted.
3. Before installing the filter element planting place Carefully wipe with pure rag. A rubber band on a new filter is lubricated with a small amount of oil. Tighten the consumable element with your hands, that is, without the use of special devices.
   

   Spinning the personally, do not make an effort exceeding 8 nm.

4. Screw the plug hole in the pan and pour oil to the MAX mark on the dipstick.
5. Run the car engine. Check the presence of oil leaps where the filter is connected to the landing place.
