Sometimes car owners are faced with the fact that when checking the engine oil level in the engine, they notice foam formations on the dipstick that resemble drops or something like bubbles. What it threatens and what to do, the AvtoVzglyad portal found out.
We are talking about an emulsion – a substance that appears on the dipstick or oil scraper neck from contact with the fluid, preventing it from mixing with the lubricant. For example, we can talk about water, which begins to foam during engine operation, which confuses the driver. Where is it from? First of all, from air masses, when moisture begins to condense with a decrease in temperature.
Although it is much worse when bubbles appear when mixing engine oil with coolant. Yes, this is unacceptable, but unfortunately this happens quite often. As a rule, the problem lies in the poor tightness of the cylinder block gasket, or in a microcrack formed on the liner of one of the cylinders. Less often – due to the “fatigue” of the antifreeze pump or due to deformation of the cylinder head. However, heat exchangers are often “naughty”. Especially in chic modern cars.
What must we do? Believe me, a caustic phrase about dealing with someone’s mother will no longer help! And even more so if an emulsion appears in the expansion tank. Before it comes to white smoke from the exhaust, showing the whole neighborhood how your coolant burns, it is better to go to the technical center as soon as possible.
Otherwise you can destroy both the valves and the liners in the engine and at the same time cause fatal overheating of the device. After all, in this way the engine loses its actual lubricating properties. Like cleaning. Therefore, it is necessary to find out the reason why the foam in the oil has formed, remove it, and then flush both the engine and the cooling system. Only after that – fill in new fluids. If we limit ourselves to replacing it, the emulsion will reappear after a while, condemning the power unit to premature death more and more quickly.
