How to stop your car engine to burn oil? In many cases, engine oil consumption is considered normal. And in many, no. How to understand that you have problems and the engine needs urgent repairs? What are the main causes of oil consumption?
As everyone probably knows, oil is needed to lubricate engine parts. Without it, the engine will simply jam. And you will be in trouble.
What do you think, how many reasons are there for an engine oil burner? There are actually few of them. See our video for more details.
The engine burns oil, but the car is not smoking? Most likely, this is a banal leak. The lubrication system itself is closed and consists of many parts, gaskets, seals. That's where they might be the problem.
Broken oil pan. It happens that when hitting some kind of obstacle, the oil pan is pierced. And of course, it starts to go away. If the damage is severe, then oil consumption will increase rapidly. How to protect yourself? To do this, install engine protection.
Engine gaskets worn out. Valve gaskets, sump, cylinder block, sensors and other mechanisms lose their elasticity, crack and begin to leak oil. This also includes the wear of seals. Usually oil seals on the camshaft and crankshaft suffer.
Worn turbine seals. If you are the owner of a turbocharged car, then you should pay attention to whether there are oil leaks. Turbine oil can enter both the intake and exhaust manifolds.
Almost all of these oil leaks can be identified visually. Periodically look under the hood and this will help to notice and eliminate the leak in time. There are severe cases when there is a puddle of oil under the car.
The second reason for the oil burner is getting into the combustion chamber. How to understand that oil enters the combustion chamber? A clear sign will be black or blue smoke from the exhaust pipe. Still can frankly stink.
Let's take a closer look at why oil can enter the combustion chamber. The first thing that comes to mind is the wear of the oil scraper rings. When they wear out, oil begins to enter the combustion chamber. The first sign is that the car starts to smoke heavily with black or gray smoke. What to do? There is no need for a major overhaul here. It is necessary to replace all rings: oil scraper and compression, i.e. make a major overhaul. Sometimes they grind or bore the engine itself. The need for such repairs may arise at different runs. It depends on the design of the engine itself and its operation. On average, such repairs can be expected for 300 thousand kilometers.
Valve stem seals. They also cause engine oil consumption. At the top of the engine there are valves that move. These valves have special seals called valve stem seals. Over time, they wear out, and oil begins to enter the combustion chamber. Only their replacement will save. It is not as expensive as capital, but it also costs money. For example, for BMW and Mercedes, prepare 500-600 greens.
It happens that the oil begins to burn out even BEFORE it enters the combustion chamber. How? There are engines where a special nozzle throws out oil to cool the pistons. And if at the moment of high load the pistons are very hot, then the oil, falling on them, can simply burn out. Such oil consumption will not be critical and is a technical feature of the engine. For example, Volkswagen 1.8 gasoline engines eat oil directly from the assembly line. Eats oil and there's nothing you can do about it. You will have to carry a can of oil with you in reserve.
And it happens that oil gets into the engine cooling system. The tightness of the engine gasket is broken and oil enters the cooling jacket.
There is another interesting point. The crankcase ventilation valve, which is responsible for regulating the pressure inside the engine. When the valves go up and down, different pressures are created, and for some reason this little valve is clogged. The engine will begin to expel oil from within itself to the outside. In such cases, a leak is observed in the area of crankshaft oil seals.
Aggressive driving and poor quality oil can also contribute to increased oil consumption.
What's with the numbers? What consumption of oil is considered the norm? If the oil consumption is more than 1 liter per 10 thousand, then do not delay with engine diagnostics. Because the outcome can be very sad.
