The internal combustion engine is arranged as follows, that for its normal operation requires a constant supply of oil to the friction and loaded parts. The engine fluid is the engine fluid. Each engine has a strictly defined amount of oil, which is poured into the system. The level of engine oil in the engine helps to control the amount of oil.
We also recommend reading the article about it, whether it is possible to mix motor oils. In this article you will learn about the basic requirements and recommendations, which must be observed during the selection and subsequent replacement of oil in the engine.
In most cars, the oil level is measured with a special oil dipstick, on which special marks "minimum" and "maximum" are put ( «min» і «max»). There are also engines, in which the oil dipstick is structurally absent. The oil level in such internal combustion engines is determined by electronics and displayed on the dashboard. The second option may be the complete absence of the oil level scale and the ignition of a separate indicator, which indicates the need to add oil only when reducing the oil level.
How dangerous is the overflow of oil into the engine
Today, the vast majority of motorists are well aware of this, that the quality and level of oil in the crankcase directly affects the quality of its operation and engine life of the power unit. Let's note at once, which affects the operation of the engine as a low level of oil, and high. For this reason, the oil level should not fall below the "min" mark.. At the same time it is not allowed to raise the level above "max".
Let's start with a well-known fact. Consequences of engine oil starvation, ie operation of the engine with low oil level, can be catastrophic. As a result, every driver must constantly and carefully monitor the quality and quantity of oil in the engine. Such control is usually aimed at that, to keep the butter fresh, met all tolerances, and its level in the engine did not fall below the critical level.
If the oil level in the engine has fallen sharply below the "minimum", then there is a fault, which must be removed immediately. Remember, it is forbidden to drive a car with a low oil level in the engine!
The oil must be topped up urgently, then immediately determine the nature of the breakdown. Operation of the engine with low oil level or without oil is dangerous and will quickly bring down the power unit, then expensive complex repairs or engine replacement will be required.
Why is the oil overflow
As for the issue of oil overflow into the engine, much less attention is paid to this aspect by car owners. The point is, that the effects of oil overflow may not appear immediately or be invisible in the early stages of the problem.
A common cause of oil overflow is insufficient drainage of used oil during scheduled replacement.. A common situation is that, that during oil change the engine is not warmed up enough before the exhaust drain, vacuum cleaner is not used, etc.. In the system with this approach can remain from 250 to 500 grams of old oil. Then pour fresh butter, and in full, which is recommended by the manufacturer for this type of engine.
Another nuance is that, that some drivers deliberately pour oil into the engine. The reason for such actions is a misconception, that if a little - bad, then the more oil, the better. This practice is especially common among those owners, whose engines constructively or as a result of wear consume engine oil, as well as due to oil leaks. You can hear from such a driver, that he poured a little oil into the engine specifically, as after a short time or active driving the level will still decrease. Next we'll talk about that, what will be, if you pour oil into the engine and what threatens to overflow the oil into the engine if the permissible level is exceeded.
Signs of oil overflow in the engine
The easiest way to determine the oil overflow in the engine is to check the probe. To do this, the car is installed on a flat surface, then the engine must be cooled 15-30 minutes. This is necessary for complete draining of the oil into the pan and more accurate determination of the amount of oil. Let's add, that it is optimal to check the oil level after overnight parking on a cold engine. If noticed, that the oil level is above the "max" mark on the dipstick, then an obvious overflow.
Another sure sign of an oil overflow is an increase in fuel consumption without other visible ones ??reasons. Pouring oil above the norm leads to that, that excess oil has additional resistance moving in the cylinders of the pistons and piston rings.
The consequence is ??they, that the crankshaft becomes harder to rotate, less torque is transmitted to the wheels. The car accelerates worse, reactions to depressing the accelerator pedal become less clear, especially at the "bottom". To compensate for losses and get the usual acceleration dynamics, the driver presses harder on the accelerator, resulting in increased fuel consumption.
Consequences of oil overflow in the engine
Oil overflow affects not only fuel consumption. Any liquid with heating has the property to increase in volume. Since engine oil operates in high temperatures, the result of the overflow is an increase in pressure on the rubber seals and other sealing elements.
Gradually, the efficiency of the seals decreases, the oil begins to flow. Such consequences of oil overflow in the engine cause the increased expense of oil, contamination of the hood space and may lead to the need to replace the seals.
Specialists also identify a group of faults, which occur due to the high level of oil in the engine:
- difficult to start the engine, especially in cold weather;
- enhanced soot formation in the engine cylinders, appearance of coke and deposits;
- increased loads on the oil pump and reduction of its service life;
- foaming oil, as a result work of hydrocompensators is broken and oil of other loaded elements worsens;
We also recommend reading the article about it, what is a compensator. In this article you will learn about the device, appointment, principles of operation and basic malfunctions of hydrocompensators as a part of the gas-distributing mechanism.
- increased smoking, excess oil enters the exhaust system, catalyst contamination;
- increasing the level of toxicity of exhaust gases;
- disturbances in the ignition system due to oiling of the spark plugs, quick failure of the candles themselves;
Must be added, that as a result of certain malfunctions of the engine working liquids from other systems of the engine can get to system of greasing (breakdown or burnout of the cylinder head gasket, defects and cracks of cylinder head and BC, wear of piston rings, etc.)
In this case, the oil level rises, as the oil can be greatly diluted ??antifreeze cooling system or fuel. Immediate engine diagnostics are required to determine the cause of the oil level rise. The simplest way is to analyze the viscosity and odor of the oil, and detecting the presence of an emulsion.
What shall I do, if you accidentally spilled oil into the engine
Pouring oil into the engine is the most dangerous then, when the unit is not new for a long time and the oil level significantly exceeds the maximum allowable. The point is, that on the worn out engine can quickly squeeze out epiploons, as well as a high probability of strong leaks.
As for the new motors, visually the problem may not appear, but that doesn't mean, that it does not exist. The oil level in this case must be normalized at the first opportunity. Next we will consider, how to quickly drain the engine oil from the engine.
The following methods can be used to drain excess oil from the engine:
- Drain or drain excess oil yourself. For draining it is enough to unscrew a drain stopper on the crankcase pallet a little. This method is the most difficult, because it is desirable to have an overpass, pit or lift. Additionally, you will need a wrench to unscrew the drain plug, removing engine protection (in the presence of), as well as a container for draining excess oil.
When unscrewing the oil drain plug on a hot motor, beware of heated oil getting on the skin or in the eyes., as there is a risk of burns and other injuries!
- If it is not possible to get to the drain plug, then you can pump out some of the excess oil through the oil filler neck. This will require a special syringe for pumping (can be replaced by medical) and a regular rubber tube (suitable tube from the dropper). You can also pump oil with a pump or just by mouth. Note, that in the latter case it is necessary to avoid getting oil into the mouth. After the procedure and removal of excess, check the oil level on the probe.
- You can also use the services of service stations or contact the express oil change station, which are usually located near large gas stations. Specialists quickly pump out excess oil with a vacuum for a nominal fee.
