After replacing the oil that. The engine is incompass or stuck after replacing the oil

A sufficiently common situation is the case when, after replacing the oil, the engine began to work louder. Increasing the noise level or the occurrence of the knock during operation can be marked both on new engines and on units with mileage. On some engines outsided sounds only "on the cold" is heard, on other engine noise is constantly and regardless of the temperature of the aggregate, on idlingunder loads, etc.

As is known, any drives of the motor, corrosion, blows and other symptoms may be a sign of a malfunction of the aggregate. For this reason, the engine of the engine after replacing the oil or knock should alert the driver. Next, we will look at why the change of lubricant can lead to stacks, noise or increased engine vibration.

The engine and sound of the engine changed after replacing the engine oil

To accurately determine what the problem is, it is necessary to carefully analyze everything possible reasons. Let's deal with the order.

1. Let's start with the fact that if after replacing the oil in the engine, a knock appeared, then this can be as a consequence and just a random coincidence. In the second case, this means that it should be excluded from the list of reasons motor oil and diagnose the engine by analyzing the noise or knocks. Various drives () can noise in the motor (), the knock may appear in the valve lid area and (knock,) or listen at the location (,). Also, mounted units (generator, GUR, air conditioner compressor) or other structural elements, such as an oil pump or cooling system, can be the source of noise. If, after replacing the oil in the engine, vibration, knock, trim, and other symptoms appeared, then in such cases the further operation of the unit is not recommended to accurately determine the cause of noise or knock. Remember, the breakdown can progress further and lead to the complete output of the unit fail.
2. Using the washing before the replacement of lubrication often leads to that situation when the engine stacked after replacing the oil. If the motor, especially with a solid mileage, was actively washed before the fill of the fresh lubricant, then the appearance of noise or knock is quite possible in its individual nodes. The fact is that in any DVS in time, the layer of resinous sediments on the surfaces of parts is accumulated. Also, a large amount of layers are available in the pallet where mechanical products of the depreciation of the unit, nagar particles, coke, old engine oil, etc. accumulate. Such sediments in the engine itself reduce increased gaps between worn-over rubbing pairs.

   After using flushing, the sediment layer decreases, as a result of which the gaps naturally increase, the engine begins to work noiser or even knocking. In such a situation, noise level or will decrease as new deposits accumulate without consequences, or an urgent need for engine repair will arise.

   As for the pallet, wash oil softens the deposits that are peeled from the total mass and clog the oil filter. The consequences are that the pressure in the lubrication system may in some cases decrease or fall to such an extent that the oil starvation will come. Diagnosis of this malfunction is complicated by the fact that the oil pump at the same time works properly, the oil level in the crankcase is also normal.

3. Lubricant that is not suitable for this type Motor, low-quality cheap product or a frank fake can also cause that noise appeared after replacing the oil in the engine. In such a situation, it is recommended to immediately drain such oil. The fact is that the appearance of noise or engine knocking indicates that the lubricant does not perform its protective properties. Lubricant may not create the necessary oil film on the conjugated surfaces, badly pumped through the system or, on the contrary, to be too small and the like. In order to avoid similar risks, it is recommended to purchase oils that are allowed by the manufacturer of the power unit to use in concrete Engine.

   It is also not welcomed by changing types and groups of oils (for example, replacing less viscous synthetics on a more viscous semi-synthetic or even mineral oil Conversely) without a preliminary assessment of the feasibility, the status and preparation of the engine. If such a transition is consciously scheduled, then note that the oil is more viscous at the time of the cold start reaches the timing, CPG and.

   Naturally, noise at the moment of starting the engine (especially in winter) and a short time after it will be louder and will be well listening. You still need to add that miscellaneous oils Even one type may differ in their properties. For this reason, you need to be prepared for the fact that on the oil of one manufacturer, the engine can work louder or quieter than on the other. As for the most motor oil, it should be purchased in proven outlets or u official dealersince on domestic market GSM today has a large number of fakes.

Unqualified oil replacement and oil filter selection

The incidence of noise from the engine can occur as a result of a low level of engine oil after replacement. The main reason is the disadvantage of oil (especially when independent service). Inexperienced car enthusiasts are simply afraid to pour oil into the engine or incorrectly determine its level by PCU or other indicators.

Also, not everyone takes into account certain nuances, having decided to replace the oil in the car itself:

• the car should stand on a flat horizontal platform, where the old oil merges from a well-hot engine or is removed by oil pump through the oil refining neck;
• before installing a new oil filter, you need to pour fresh engine oil. This is necessary in order that, upon subsequent startup, the pressure in the lubrication system immediately came to normal;
• after filling the main part of the lubricant, it is necessary to withstand a small pause of time. During this gap, the lubricant "dissolves" in all parts. Next should check the level and add oil if necessary.
• now you can start the motor, oil pressure lamp on dashboard Must go out.
• during the operation of the OI, after the first launch, it is necessary to inspect the place of fastening of the oil filter for possible leaks. Next, during the operation of the vehicle, the engine should be regularly examined, oil filter And check the oil level in the crankcase is no less than once every 3-4 days. Most optimally carry out such checks before each trip.

Now a few words about the oil filter. This element can also affect the operation of the lubrication system, which leads to an increase in the noise level from the engine. The fact is that oil filters can have different resistance. If you use a high resistance filter in parallel with the fill with a high viscosity, then the bandwidth of the filter element will decrease.

It is quite obvious that the efficiency of the engine lubrication system will be broken, the details will be lighted worse and the engine will become noise. For this reason, only high-quality filters recommended for this type of engine should be installed on the machine.

That in the end

As you can see, the reasons for the noisy operation of the motor after replacing the oil is quite a lot. To avoid possible unpleasant consequences helps the regular replacement of lubricant and filter, the use of high-quality engine oil of one type and manufacturer, failure or moderate use of all sorts of additives in oil and washing.

Finally, add that before replacement it is necessary to try to merge as much exhaust oil from the engine as possible. This approach allows minimizing the amount of old oil, which inevitably remains on the details and in the pallet.

This statement is true in the case when washing was used or a transition from one type of oil to another was used. If "testing" remains too much, then after mixing with a new lubricant, the latter will have a deterioration. useful properties and reducing the service life. As for the engine, mixing the old and new oil can also cause its noisy work just after replacing the lubricant material.

Causes of bad engine operation

The engine of your car has an impact of both the quality of fuel and engine oil.
Cleanliness of oil affects the resource, power and reliability of the engine, as well as its environmental performance. Motorists often suggest that after replacing the oil, a knock in the engine appeared.

Motor vehicle Must work like a clock. Every car owner dreams about it. Therefore, you need to show high attention to your car, look after the smallest detail. To the car engine has always been in good working condition, the autlistant requires rules maintenance Auto that includes replacing the oil in the engine. It happens that after replacing the oil, the engine began to knock and, in general, working louder.

Hardly at least any car can be insured from breakdowns, among which there are problems,
eliminated independently. However, you can encounter serious faults that are eliminated only at a hundred. As soon as we hear noise in the engine, immediately begin to think about the reasons and try to eliminate them with our own hands.

If the engine began working louder, then it is likely that:

1. Problems with a thermostat or gas distribution system.
2. Problems in the ignition system.
3. Problems with the work of the carburetor.
4. Problems in an electrician or power system.
5. The use of low-fuel.

In this case, the engine will work as a tractor. A knock appeared, the engine began to smoke, work louder. And all this happened after replacing the oil.

Engine operation after replacing oil

If a knock appeared, the engine began to buzz louder and even smoke, it could be a consequence:

• insufficient amount of oil;
• use of low-quality oil (buy fake - today is not uncommon);
• oil pollution;
• contact antifreeze into oil;
• worn or damaged oil pump;
• use of high viscosity oil.

High viscosity lubrication in the cold makes it difficult What can serve the formation of loud sounds and a knock in the upper valve mechanism.Usually oil filters are always ready to cope with their work, however, the filter must be changed periodically,otherwise, he will break, after which the valve will work, opening the channel for lubrication when the filter does not havethroughput, which is needed for the passage of sufficient oil.

If the metal knock has become louder with increasing revolutions, it can be caused by low oil pressure, increased gap in valves or damaged details.

The knocks are heard after the start of the cold engine when the oil did not have time to reach the bearings.
In a specific range of rotational frequency crankshaft The knock may not be heard. The crankshaft knock, deaf at idle, begins to be better and clearly knocking with increasing rotation frequency.

The cause of bearings can be:

• entering mechanical impurities or water in lubrication;
• poor-quality oil or its insufficient amount binding;
• insufficient roughness of the shek.

The knock disappears as soon as the lubricant enters the bearings. This happens in a couple of seconds.

The knock will be heard when you run not only cold, but also with heat, and when you did not warm the motor. The camshaft knocks two times less than the crankshaft. Sound due to large gaps or an insufficient amount of lubricant looks like a frequency on a knock camshaft, by tonality - ringing.

If the engine with the valve gap hydraulic gaps appears, it may be a problem in the lubrication system. It happens, after replacing the oil, the engine "calm down" and will work normally. However, it is after replacing the oil we hear a distinct knock of the motor.

The reason for the knock may be the fact that the engine of the car is new. He involves a small escape - 15 thousand kilometers. In this case, some gaps are not immediately filled with oil.

How to fix faults

Categories Sounds in Engine

First of all, it is necessary to make sure that the sound comes from the motor, as the pendant parts can knock, graduation system, engine mounts, attached elements. With one click on the pedal, you can exclude all the sounds that can be published by transmission.

Engine swaying can help reveal the sounds that create engine suspensions, crankcase protection and release system. The buzz speaks of a malfunction in the generator, camshaft or water pump drive.
Spring can talk about problems in:

• slippage of the generator belt;
• freezing of the water pump;
• the absence of lubricant fluid in the generator bearings.

If you remove the generator belt, you can answer the question where sounds are published.

Sounds coming from cars can be several categories.

1. Sounds resembling a ringing knock are heard from the top of the engine, from the valve mechanism. It is necessary to adjust the valves. Perhaps the valve clearances are increased and worn rockers.
2. Metal sounds resembling rustle. They come from the middle of the motor. Poor strained chain can be the cause of strange sound.
3. Low tone sounds with a lower frequency that comes from the bottom of the motor. Such sounds speak of wear of the cylinder-piston group, crankshaft necks and liners. Slow growth oil pressure gives roar with a cold engine. Low level Oil, oil pump wear, incorrectly selected lubricant or oil filter.
4. Metallic sound will appear when overclocking cars or with an increase in the rotor of the motor.
   Early ignition, poor-quality gasoline, reduction of combustion chamber, motor overheating,
   Incorrectly chosen candles, problems in the vacuum-proofreader of the distributor of the distributor.

What to do

It happens like this: replaced the oil - a knock appeared, the motor earned louder, began to dreamed. Knowing people speak like this: it warms up - stops. But, if the knock did not stop, you should consider the cause of such an aggregate work.

It happens that on the summer viscosity indicator, the oil, which was poured before, to the last fill, forms a film on the details. After filling the lubricant with the details, this film was washed off and a layer of thinner appeared. Perhaps this was the cause of unusual sounds of the engine.

During the operation of the car, it takes place of detail, which is manifested in increasing the gaps that create
knock in the motor. To remove knocks, change the details and regulate the gaps. However, that the repair be bought is budgetary and has been performed quickly, additives should be pouring and dense oil. After the fill with a viscous lubricant can recover normal engine operation.

The smaller the number in the numerator with the "Z" index in the viscosity classification (GOST, SAE) or in front of the letter "W", the less the viscosity of the lubricant at low temperature.

Often car enthusiasts are poured lubricant liquidthat does not fit their cars. Therefore, you should know which oil is intended for your car. Some expertise's experts advise not to change the oil, which has recently flooded, and roll the car a couple of thousand kilometers and again pour the same lubricant liquid. But in this case you need to pre-check the gaps.

If after the fill of the lubricant appeared a knock and the motor began to droop and work louder, then it may have antifreeze into the oil. In this case, you need to check the level of antifreeze. It should not decrease. The car should be sent to the service where the leakage of antifreeze will find and change the liners.

The sound of the engine that began to work louder or peel after filling the lubricant must push the auto owner to check the oil level. If the level is low, then it is necessary to add lubricant to a permissible maximum. If, after filling the oil, the sound has become louder, check its pressure. Low pressure will indicate a burning light, which indicates a serious malfunction and that it cannot help the oil to achieve the upper valve mechanism.

If a damaged oil pump or scored filter It was the reason that an unusual knock and the car began to "growl" louder, then it is worthwhile to change the pump or filter.

Foreign knocks during the car can cause a sense of uncertainty that you know the nature of their appearance, you can consult with knowledgeable motorists. Perhaps it will be necessary to disassemble the engine or take up inexpensive and simple repairs.

Video "Sound of the engine after replacing the oil"

Almost all motorists know that the oil needs to be changed. In addition to completed blondes, who and the car are running with difficulty. We will proceed from what you know about the need to replace the oil. And also from the fact that you are this moment, at least interests. Now let's figure it out, why change oil, and what consequences you can expect if the oil is not replaced on time.

Timely replacement of oil in the engine of your car guarantees its normal performance. The frequency of replacement depends on the car model and the type of oil used. As a rule, oil changes after a run of 8000-10000 km. To begin with, we will remind you why we all change the engine oil. The oil envelops the lubricated parts of the engine, leaving the elements on the surface of moving relative to each other, the so-called protective layer (very thin layer of oil). This layer helps reduce friction force between them. The oil practically eliminates the friction of parts when the engine is running. This allows you to significantly reduce wear of parts and extend their service life. But any oil has its own resource, after which the properties deteriorate significantly. In addition to reducing friction, the oil performs the engine cooling function. Over time, it is diluted and much worse thanks heat.

With a large run on one oil, it is diluted and worse copes with friction of parts. With increasing friction, all engine nodes experience significantly superior loads. At best it will threaten increased flow Fuel and a decrease in the service life of parts, but at worst - the motor can "bury". When a knock on the engine appears overhaul Already not to avoid, and its cost is hardly pleased.

What reduces oil life?

There is such a thing as "aging oil." It suggests that over time, additives burn in the engine and pollution accumulate. As a result, the oil becomes "dirty", that is, loses its color, structure and properties. So, ceases to perform the functions that are assigned to it. Therefore, it is necessary to merge the old oil and pour into the engine new. You also need to not forget to replace the oil filter, which also stops performing its functions, as a result of contamination.

The biggest test for oil is urban riding for short distances, which does not allow oil in the engine to warm up to the optimum temperature.

As a result, a large amount of fuel fall into the oil, which leads to the depletion of oil additives. And the presence of water in oil causes a change in the characteristics of the engine oil. Thus, citizens who are often driving around the city or short distances should pay special attention to the condition of the oil. Since it is with such a car operation that the oil is exposed to the greatest wear.

Naturally, continuing to ride on the exhaust oil, you are thereby much harm to the engine. After all, the oil does not perform the functions assigned to it. This leads to corrosion, increased wear of spare parts, and even overheating the engine. Another possible result may be clogged oil channels.

In order not to resort to expensive repair, it is necessary to be guided by some rules. First, do not allow too long idle your car without work. If the engine does not start a long time, then all oil flows into the crankcase and after starting the motor works almost dry.

Secondly, do not skip the oil replacement time. If, for some reason, you could not have replaced the oil in time, then it threatens serious consequences. Immediately, of course, you should not panic. If you missed the oil replacement by 1-2 thousand km, then your motor does not threaten anything. Extra 5-10 thousand on the old oil is already more dangerous.

In addition to the run, it is worth watching and simply for the time of oil. Even with a slight run, it is undesirable to ride in one oil for more than a year, so when this period is reached, a replacement is also necessary.

How often do you need to change the engine oil?

Periodicity of oil replacement for each car is individual. This should be described in the instruction manual for your car. If you use a brand a hundred, you should notify the wizard about it. If you have slightly crushed the oil replacement, you should not panic immediately. One or two thousand kilometers will not cause serious harm to the engine. But more than two thousand, passed on the spent oil, can already seriously affect the resource of your engine.

On the territory of Ukraine and the CIS, it has long been recommended to change the oil more often, reducing the mileage embedded in the instruction manual of the car. This is caused by fuel quality, which does not comply with generally accepted standards and standards. If you follow the mileage and change the oil on time, the engine will work smoothly, and the car will not let you down at the right moment.

What problems will have to face when the oil is untimely replaced?

Operating a car with old oil can entail very serious consequences. In this article we will tell about the most common breakdowns.

Before connecting rod inserts

The most common cause of turning rolling inserts is the late oil change. Exhaust engine oil poorly affects the lubricant system and working mechanisms. As a result, the oil canal is clogged. The larger the exhaust engine oil accumulated, the larger loads are subject to connecting liners, and, therefore, and excessive heating, which leads to a stress of connecting rods.

Worn parts of turbochargers

Operating a car with motor oil can lead to damage to the rotor. In the rotor, when using spent oil, the shaft of the turbocharger and bearings take place, which leads to the formation of deep scratches on them.

In addition, the use of polluted engine oil leads to the formation of a furrow and leads to the destruction of bearings, which entails damage to the shaft and the casing of the turbocharger. In addition, contaminated engine oil causes clogging of the turbocharger lubrication channels, which leads to its enclation.

Worn engine parts

The most common cause of the wear of engine parts is the poor quality of the lubricant when the engine oil has a low viscosity. This leads to the rupture of the so-called oil film between the cylinder and the piston. Since the exhaust engine oil cannot cope with the neutralization of soot and acidic compounds formed during combustion.

Also, the wear of parts occurs due to the lack of engine lubrication or the deterioration of its quality, which leads to a sharp increase in the temperature of the individual parts of the engine, and it lasts until the interacting parts are missing.

In addition, the late oil change can lead to bending or even destruction of the valve. The result of damage to the valve may be a gas leak in the combustion chamber.

Effects undime replacement can be very serious because the engine oil not only reduces friction force between driving items, but also lowers the temperature between them
