Many drivers just do not notice the color of the smoke coming out of the exhaust pipe. But, it is the smoke according to which we can find the main conclusions. For example, if it is blue, then the engine spends an excessive amount of oil.
Mostly blue smoke appears when oil enters the cylinders of the internal combustion engine. There are shades of such smoke. It can be light blue or whitish-blue.
If blue smoke is visible, then the silt unit spends a great amount of oil. If it is spent 0.5 liters per 100 km, then such smoke appears, usually, when the speed is set. Car owners should remember that there may be an accelerator in the car that cleans the exhaust from oil, even if the consumption is high.
The main reason for the blue smoke is the old cylinders and pistons. The rings located at the top are coked and cannot perform their function. Among other things, the grooves of these parts can also wear out. If the rings are not worn out, then the grease can get into the cylinders. As a result, the rings will pump oil continuously.
Blue exhaust can occur if the car has not been started for a long time. At the same time, rust may form on the rings and cylinders.
Also, blue smoke may appear if the motor repair technology has been violated, when the surface of the repaired cylinder is irregular in shape. The use of low-quality rings and pistons can also lead to a blue exhaust.
But blue exhausts can be seen on new cars. This happens when the engine warms up. It will disappear over the time. This is due to the fact that the motor elements occupy their position and the desired shape when it is run-in
