The increased oil pressure that occurs in the engine when the lubricant overflows can adversely affect the operation of the engine, eventually leading to serious malfunctions of the power unit. At first glance, oil overflow does not seem to us to be such a serious problem, but such can lead to “oiling”, deterioration of oil seals, wear of the oil pump and a number of other problems. Let’s talk in detail about what will happen to the engine, if you pour in the engine more oil than it is supposed to. And about how much money you can get for your old car, you will be told here: https://scrapmycarnear.me.
What is the threat of a high oil level in the engine?
Possible engine problems
When the oil overflow in the engine there is a considerable growth of the lubrication pressure, as a result the oil starts escaping through the oil seals and worn gaskets, the grease can get inside the combustion chamber which leads to the increase of the engine’s smokiness. Eventually, the oil seals wear out, after which the engine needs to be opened up and overhauled.
Excessive oil pressure can lead to the following problems:
1) spark plugs get greasy and completely fail;
2) engine power output decreases considerably;
3) there are problems with starting the engine;
4) there is a significant increase in fuel consumption;
5) the engine begins to smoke seriously.
A common problem with oil overflow is the malfunction of the sensor, which indicates fuel consumption. As a result, it is necessary to open up the engine and change the defective electrics, and this is a significant expense for every car owner.
The crankshaft in conditions of such increased oil pressure is like whipping up grease, which starts foaming, actually not lubricating the moving elements of the engine. Air bubbles in the oil and inhomogeneity of the technical liquid lead to rapid wear of the entire engine.
The load on the oil pump, which often fails to cope with pumping large quantities of fluid, increases significantly, after which its critical breakdowns are noted, and replacement of the oil pump is an extremely expensive and complicated procedure.
It is not uncommon to see defects and even cracks in the cylinder head gasket, after which antifreeze begins to enter the combustion chamber. In such a case, a comprehensive diagnosis of the engine is required, this will identify specific problems, the power unit is opened and its overhaul is performed.
Consequences of increased pressure due to a high oil level in the engine
What to do if the oil overflowed?
On the Internet on thematic forums you can read the recommendations of supposedly experienced car owners, who advise in such a case not to get nervous, because the extra oil will quickly burn, and more any problems with increased pressure in the system will not be. However, any professional will tell you that inaction in such a case will be disastrous for the engine. Therefore, if you have inaccurately poured oil into the engine, it is necessary to immediately solve the problem.
The easiest way in such a case is to use a tube from a dropper and a small syringe. Such a tube is dipped into the oil in the engine through the filler neck and the grease is gently sucked out with a syringe. Just a couple of minutes of work and you can siphon off half a liter or more of oil from the engine. You can also just open the drain plug on the crankcase and drain the excess oil. Remember only that it is necessary to act very carefully, to give the lubricant to cool down so as not to get burnt by the hot technical liquid.
If you accidentally pour oil into the engine more than it is supposed to, then this leads to an increase in pressure in the system, and it is not only wear of seals and gaskets, but also possible problems with the crankshaft, the valve cover, the general wear of the engine is noted, after which the driver is required to perform an overhaul of the engine. If you overflowed the oil in the engine, you must pump it out through a thin tube or simply drain it by opening the bottom drain plug in the crankcase pan.
