Replacing the oil filter: recommendations and comments. We determine the oil starvation of the engine: the causes, signs and consequences of the scored oil filter why

Engine oil performs several functions: it lubricates fuel, cools and lubricates them. Without motor oil The engine immediately beaten, the first of the building will be released with crankshaft liners, which will turn into foil, also the bulbs will also be on the crankshaft itself. In principle, other details will not have time to fail, since the liners without oil turn into foil for a minute.

The oil starvation of the engine leads to irreversible consequences, the crankshaft is damaged. And it often happens that the crankshaft bursts remain more than the last repair size, and this is the purchase of a new expensive detail.

Oil starvation of the engine is not that oil is not completely, it simply did not have enough some details due to a low level, the small bandwidth of the lubrication system due to clogging or other reasons. Not necessarily, the entire engine does not get the oil and most often lacks individual engine nodes.

Causes of Oil Fasting Engine

There may be several reasons.

There is no sufficient amount of oil in the engine low level, someone has stuck and did not fade
The oil did not change for a long time, thickened, gathered by pieces along the walls of the engine and does not flow into the pallet
The grid of the oil worker has been hampered
A oil filter has been hammered, and the bypass valve jammed
Jinned oil nozzles in the open position and the pressure in the system fell
The reducing valve on the oil pump broke and the oil on it flows into the return
Craveled oil canals
You yourself think about the reason (write off whenever possible in the comments, what other causes may be)

1. Any engine consumes the oil on a carbury more, some less. If you don't look like a hood for a long time and not to check the oil level, then one finely the oil will become so little that it will stop getting to the oil worker. At first it will happen when the car will turn around, climbing the slide, then - when the speed will be turned and the oil under the action of the centrifugal force rushes away from the oil worker. It, of course, little things, but gradually oil will become less and less, but it will cease to enter the most remote corners of the engine.

2. When the oil does not change for a long time, there is some thick and non-tech fuel oil in it, which loves to gather on the walls of the block and in the head. The liquid fraction is becoming less and from here we look at point 1. This particularly often happens on modern carswhere the manufacturer recommends enlarged oil replacement intervals (Long Life, up to 30,000 km run). And if there is no strongly responsible masters on the service, which are not all the old oil, be problems. Change the oil at least once every 10,000, and better even more often.

3. Those kias that are formed in old oil (watch item 2), can score the grid of the oil worker and then the oil will cease to flow into the lubrication system. Although the grid is clogged for other reasons.

4. The oil filter consists of a housing and the actual paper filtering element. All the smallest particles of dirt clog pores in paper and with time bandwidth The filter is lost. To prevent oil starvation when the filter has been hammered (it does not happen if it does not happen if changing the oil on time, although there is also from air filter And from the operating conditions for dusty roads, how many dirt will fall into the engine), in the filter it is provided by the bypass valve, in the normal position it is closed, but as soon as the bandwidth is lost, the valve opens under the action of the discharge created by the oil pump. When the valve encourages, then naturally the oil does not get anywhere, and the lubrication system will circulate less and less and less oil with less pressure.

5. In some engines, mostly turbined, there are oil nozzles that spray oil on the pistons to cool them. Nozzles open under pressure, and when oil pressure No, they are closed. If the nozzle is defective and opens, the pressure in the system will decrease, which means the oil will not reach remote corners of the engine. Although if you have a budget foreign car with low-power enginesuch as Ford Focus or Chevrolet Aveo., then you should not worry, such a system is missing in them

6. On the oil pump there is a reduction valve that is designed to relieve excess pressure. If it is broken, then the pressure in the system will fall, especially on low revolutionsWhat will lead to oil starvation.

7. The engine lubrication system consists of oil canals. The most vulnerable part is the crankshaft. There are oil channels in the crankshaft by which the oil comes from the root neck to the connecting rod. These channels are very narrow and can very easily clog off all the mud, which will lead to oil starvation of connecting rod liners.

8. You can still come up with some reason if you missed something in the comments

Consequences of oil starvation

The consequences are terrible. For example, when crankshaft It rotates, it does not come into contact with the inserts, there is always oil between them, the so-called oil wedge. But when the oil is not enough, it ceases to go to the crankshaft and inserts, then this oil wedge disappears and the shaft begins to rub on the liners and from friction and the shaft raised due to this temperature is clinic, but since it continues to rotate in the inertia, then this wedge breaks away, The most dying the surface layer of the metal from both surfaces. The outcome is the liner in Foil, on the crankshaft of deep bulbs.

If the oil pressure is methodically gently begins to decline in the system, that is, it passes through the pipeline less, first of all suffer skeeping inserts crankshaft, since they are located farther and the oil to them is suitable for the residual principle.

But before that, the hydrocompensators are most likely stuck (unless of course they are), and the turbine suffers very much from oil starvation.

If the oil at one point suddenly stopped acting into the lubrication system, then it is most likely to first go to the native bearings, as they are closest to the pump and get the first part of the oil.

Restore such an engine is very difficult and expensive, in addition to the replacement of the liners, the crankshaft grinding is needed if it falls into the repair size or buying a new one.

Oil filter plays an important role in the lubrication system. Oil, circulating in the engine vessels, washes off wear products and chop. The filter, in turn, holds various mechanical particles, skipping clean oil. Due to the operation of the cleaning element, there are no solid components of the dirt between the driving parts of the engines, which largely contributes to its long service.

Oil filter replacement frequency

If you want to save your engine in integrity and safety, we advise you to regularly change the oil filter. Oil filter is the main protection crankshaft and moving parts of the engine. With its unstable operation, the engine machine quickly fails.

If you have previously neglected replacement recommendations oil filter, then be sure that this amount of dirt has been accumulated in it that it hardly skips oil or, in general, it does not pass at all.

The latter assumption is exaggerated, as the design oil filters Provides a bypass valve, which means the circulation of oil in any case, even when the filter is clogged. But you can imagine what oil it will be. Therefore, do not bring the situation to the critical point.

Various car concerns and oil filter manufacturers recommend different periodicity of changing cleaning components. As a rule, these deadlines are very small, as manufacturers care about their reputation and therefore recommend frequent replacement filters.

Experts are advised to replace - every 8-12 thousand km, which coincides with the deadlines for the replacement of motor oil. However, if you have any doubts about the purity of oil or have been manifested by any bad signs, you can replace the filter before the deadline. The benefit of timely replacement is obvious, judge for yourself if the engine can be purchased from $ 2000, new filter You will cost $ 10-20. Therefore, do not leave the air filter replacement for later.

Signs of a clogged oil filter

If the oil filter has become unusable, then you will most likely not know until you contact the car mechanic or remove it yourself. It's all about its bypass valve, which has already been written above. With a scoring filter, it will skip the crude oil, which is still better than its complete absence. But not everything is so ambiguous how it may seem at first sight. To begin with, listen to your "horse".

Overheat. When moving parts of the engine will rub each other without sufficient quantity lubricant, there is excessive heat. In connection with this factor, the engine mechanism begins to wear faster, which causes additional load on the cooling system. In addition, ne filtered Pollution form a precipitate and begin to be deposited in the engine, which causes a decrease in thermal conductivity. The outcome of this is the engine overheating. Normal work Motor passes in temperature not higher than 80- 100 ° WITHIf this indicator is increased, this indicates the pollution of the oil filter.
A leak.Faulty or scored filter reacts poorly to change temperature mode inside the motor. Faulty oil filters can break or burst, which leads to oil leakage. Therefore, if you notice a leakage of any liquid from your car, then contact the master immediately.

Where is the oil filter

If you came to the opinion that independent replacement Oil filter on your shoulder, before starting the operation, you must clearly understand the entire sequence of your actions.

Find the oil filter. It is located at the bottom of the engine on the pallet. (see photo).

Further, in front of the replacement procedure itself, drain the oil. It must be merged with a hot engine, for example, after the trip. If, the car costs a long time, then run the engine so that it is heated to the working temperature mode.
Keep in mind that the oil brand poured into the engine must be analogous to the one that was before replacement. If you decide to change the brand of oil, then rinse the lubrication system washing oil either oil used subsequently.
Flushing implies drainage of spent oil, and then the bay of the new oil to the lower level. Old oil can not be merged on the ground, substitute a pre-prepared container. After draining the spent oil, start the engine so that it will work for 10 minutes on idling. Next you can change the oil filter. After replacing it, fill the new oil to the required level - the top mark on the dipstick.

After this procedure, prepare all the necessary tools and proceed to replace the oil filter.

Oil filter replacement tools

New filter. The price of the product depends on the preferences of the selected oil brand. Experts recommend labeling 5W30 oil.
Tara for draining waste oil . Choose a shallow but pretty wide Capacity to minimize the possibility of spilling oil to the ground.
Latex gloves. Designed to protect hands from burns that can be caused by hot oil when the drain plug is unscrewed the crankcase.
Gate. Needed with a strongly tightened drain plug.
Replaceable end head. It is used in conjunction with the gate, in size should correspond to a drain plug.
Ribbon key. If access to the full-flow oil filter is limited, it will allow it to turn it out without any interference.
Caid key. Fixed on the end of the filter and then rotates with a snoring drive or gate. The sizes must correspond to the filter housing.
Ribs and old newspapers.

Step-by-step instructions for replacing the oil filter

To have free access to the oil filter and crankcase pallet, raise the car with a winch or beat it onto the overpass. You can also use the jack and backups.

Attention! Do not work under the car, under-pass only under the bumper or holding one by the jack.

Lie under the car and define location Drain cork plug crankcase and motor oil filter. Keep in mind that the nodes of the exhaust gas production system during the entire replacement procedure will remain hot. Therefore, with unprotected skew, avoid contact with disintegration surfaces.

So, make sure the horizontal arrangement of the car on the lift or backups, warm the engine to operating temperature. Hot oil is not so viscous, so it is better to wash the precipitation and sludge. Then muffle the motor and remove the cover from the filling neck.
After that, abandon the car again and set the container to drain the oil under the crankcase pallet. Observing precautions, unscrew drain plug From the bottom of the pallet crankcase.

Give oil freely drain in the canister, adjusting it to the location as the jet pressure is mounted. Featured oil check for the presence of metal sawdust in it.
After all the oil stalks, be sure to wipe the drain plug with a clean cloth.
Wipe the surface of the pallet around the drain neck, screw the plug in place and tighten it tighten it with a wrench (preferably dynamometric to avoid breaking the thread).
Slide the container to drain under the oil filter.
Using a special key, loosen the oil filter clamp. In the process of twisting, the filter body may be damaged, which does not matter, since you definitely change it to a new one. When turning out the oil filter, the next advice will help you. In order to remove the filter, you need to use a special key. In the absence of such a key or a similar puller, you need to break the filter housing with a screwdriver and, unscrew it using the lever. The filter should punch as close as possible to its bottom to prevent damage to the fitting. In addition to this method, you can unscrew the filter with two hands, pre-wrapped his gross emery paper.
After you finally remove the filter from the block, make sure that the rubber sealer shot together with the filter, if not, then gently separate it from the walls of the engine block.

Clean tissue napkin wipe the planting surface of the filter on the block. If the old rubber gasket still remains on the engine, use the scraper.
Next, you need to make sure that the new filter according to its size corresponds to the old cleansing element. If everything is in order, then the next action will be the lubrication of the sealing gasket of the new filter with fresh engine oil. After that, you can screw the new filter into the engine, adhering to the direction of rotation specified by the arrow on the filter housing. When tightening the oil filter, do not apply any keys in order not to damage the gasket. When the filter is sprinkled with a gasket to the surface of the block, tighten it onto ¾ turns.
Next, you need to remove all the tools from the car and lower it to the ground.
After that, you need to find the filling hole for the engine oil and remove the cover from it. Next, you should take a funnel and pour fresh oil into the receiving neck of the motor. Bay somewhere 3 liters lubricantYou need to wait a few minutes so that the oil is glass into the pallet, and then check its level over the measuring shutter. If the level is located above the lower mark, start the engine to circulate the new oil.
When the engine works for a minute, it is necessary to drain it again and look under the bottom of the car, checking the presence of leaks through a drain plug and full-flow filter. If necessary, tighten the mounts so that there are no leaks.
Oil filter is filled with fresh lubricant in one minute. After that time there is a need to re-check the oil level. If it is not enough, then tighten a little more, bringing the level to the top mark on the probe blades (spend the repeat check after a few minutes after the engine is turned off, the oil during this time completely stalks into the crankcase pallet).
The first few trips after changing engine oil as often can be measured its level.
The fusion spent oil is not suitable for anything, therefore it must be commissioned to a special reception. It can not be poured onto the ground or in the sewer, as it is very dangerous to the environment.

Conclusion

As you can see, nothing complicated in the procedure for replacing the oil filter is not. With this task you can handle yourself. So that the whole process of replacing the oil filter has been more clear to you, we advise you to view the following videos:

Oil filters are among the most important elements. maintenance car, because motor oil is "blood" of your engine vehicle. Its main purpose is to lubricate the engine elements of the engine and output or stop the polluting elements through the oil filter. Oil filter, along with engine oil, work to protect the engine from entering into it polluting particles that can damage the motor and turbochargers up to the dismissal of them.

How do oil filters

Oil filter elements

Housingwhich serves to preserve the filter elements.
Outputs for the input and oil exit; threaded hole In the center, with which the filter is attached to the engine.
CONSTRUMENTAL VALVE Rubber Cover; It prevents oil pouring back to the filter when the motor is turned off.
Spring, it, together with the emergenant valve, delays oil from pouring into the filter in the non-working condition of the engine.
Filtering materialwhich can be made of synthetic materials, cellulose fibers, polyester or glass. Responsible for cleansing the oil, delaying mechanical impurities.
Central tube Of the steel is responsible for returning the spent oil back into the engine.
Safety valvewhich is located with back side opposite the threaded hole. The valve serves to stabilize the pressure.
Filter cover and sealing ring They are responsible for the tightness of the equipment.

How does the oil filter work?

Before you get into the engine, the oil passes through the oil filter. Oil pump delivers oil into a filter where the crude lubricant passes through the filter element, which delays pollution. The filter is located primary and secondary media types. Primary detaining large particles, secondary - small (size from 5 microns). After filtering the oil through central hole Pushes into the engine. Over time, the filter element remains more and more pollution, so it is fundamentally important to make regular filter replacement.

Why is the oil filter fail?

The filter element is clogged with mechanical impurities;

Non-registration oil change;

Wrong selection of engine oil, both for the engine and for the oil filter.

What are the symptoms of the filter malfunction?

Oil leakage from filter or filter housing.
Engine overheating.
Lamp emergency pressure Oil does not shine more than 5 seconds. But on this basis it is hard to identify a malfunction, as the lamp can be turned off, even if the filter is faulty. This is due to the fact that when filter contaminated, the oil can go on the bypass channel, which allows you to circulate oil without entering the filter. This prevents the engine from oil starvation.

What are the consequences of a malfunction?

Faulty filters cease to delay mechanical pollution, respectively, dirt and harmful impurities enter the engine and turbocharger.
A disabled filter can lead to damage to the engine walls and pistons, while oil and chad come out through the exhaust pipe.
And finally, the oil filter malfunction reduces the car's mileage without damage.

Oil filter in the operation of the turbocharger

We all know that the oil is playing a key role in the long-term operation of the turbocharger, and often precisely oil (oil pollution, unreasonable replacement Etc.) become the cause of breakage of the turbocharger. Dirty oil kills turbocharger, it affects the turbine much more than any other part diesel engine. With extreme loads, the rotation speed of the turbine shaft can be 250 rpm., And at that time, the engine oil is the only thing that cools the turbine gives it a lubricant and relieves from friction of metal parts about each other. That is why it is vital to keep oil clean, and the oil filter is good - this is best defense Your turbocharger and engine. Turbocompressor has to work in heavy conditions: on the large turns And at high temperatures, and pure filtered oil will save the turbine from wear.

As mentioned above, a lot of contaminants remain on the filter element, which the system cannot withdraw independently, so do not forget to check the filter cleanliness from time to time and change it if necessary. Oil filter will extend the operation of your turbocharger and engine.

Oil filterIn English, it sounds like Oil Filter - provides cleaning of engine oil from extraneous impurities falling there in the circulation process. Its undoubtedly can be called one of the key elements of the lubrication system of any engine internal combustion. Oil filter is located at the bottom of the engine.

Types of oil filters

At the moment, the automotive is common:

full-flow
partial accounting
combined filters

Full-flow Filters have the most simple design and immediately passed through the filter unit all the oil coming from oil pumpwhich after that is fed to all points of the engine lubrication. The oilfilter Works based on the bypass valve regulating pressure in the lubrication system. If the oil pressure of the oil exceeds the allowable value, it reduces the filter bypass valve. This lies a certain lack of such a design, since filter clogging, the oil flow slows down, the internal pressure rises, the bypass valve opens and passes into the system contaminated oil. The bypass valve on one side prevents the immediate breakdown of the engine due to the cessation of its lubrication, and on the other, it allows you to circulate with dirty oil, which is why the filter condition needs to be monitored very carefully.

Partial report filter oil engine Cleans oil longer than full-flow. In systems where it is applied, the oil is cleaned gradually, circulating immediately in two circuits: straight - from the pump to friction zones, and cleaning - from the pump, through the filter and to friction zones. In the process of circulating oil, different contours are mixed, which ensures the cleaning of the engine lubrication as a whole. Such systems are able to maintain oil in good condition over a long period. Their weighty advantage - even when the flubble filter and broken valves, the oil flow will not stop and the engine will work.

Combined Systems are created using the technologies of both previous types. Here the oil filter device guarantees the maximum quality of oil filtering and the largest use of it.

Construction of oil filter

Almost every modern oil filter is not collapsible. But those nonsenters have a lot of cars (German, American) have a collapsible oil filter, providing the ability to replace the filter element. The main advantage, such a filter - the possibility of replacing only the filter element, and not the entire node, which significantly reduces the maintenance of the car service.

Oil filter device.

Inside the device case, a filter element and a pair of valves are placed. One of them is an erect, designed to eliminate the return current of the oil. Another - bypass valve, providing a stream of engine oil, even when clogging the filter and a breakdown of the MEETING VALP. The bypass clan is also triggered when using oil with an excessive viscosity, characterized by stroke filtering.

The bypass valve provides the circulation of engine oil even with a complete failure of the filter. The task of the centered valve is not to produce an edge oil when the engine is turned off so that its circulation and motor lubrication began simultaneously with its launch.

Operation principle of oil filter

Common breakdown of oil filter

The deterioration in the engine, the black exhaust during podagazak, fall or increase the oil pressure, the ignition of the corresponding lamp on the control panel - all this may be signs of a malfunction of an oil filter.

In addition to clogging the filter element, the problem may be associated with the elastic loss by the modern valve. It is manifested in the periodic short-term inclusion of the controller on dashboard, most often immediately after starting the engine. This is due to the fact that during the parking lot with the motor turned off the oil flows from the filter body, and when it starts, it starts to work without proper lubricant.

The oil filter replacement is mandatory during the oil change. For this string, he has time to clog.

Solve the problem is simple: you need replace oil filter or filter element if it is a collapsible model. Suspecting the wrong filter operation, it is impossible to delay with the elimination of the problem, because any deterioration in the quality of the engine lubrication is its and accelerated wear, which is fraught with much more serious faults and overhaul.

Replacement frequency

No oil filter is distinguished by outstanding durability.

Exceeding life threatens intensity violation and cleaning quality. The oil is not cleared and remains dirty, which speeds up the wear of parts of the engine.

Oil pump malfunctions will inevitably lead to disorders in the operation of the internal combustion engine lubrication system. 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 engine failure, resulting in a complex and expensive overhaul Power unit.

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.

Reduced oil pressure in the system.
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;
using non-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.

Oil pump in the car has enough long term Services and breaks infrequently. Most often driven to breakdowns incorrect operation car Engine, non-quality repairs Or the use of low-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.
