Death Sentence: Why White Carbon Deposits on Spark Plugs Are More Dangerous Than Black Carbon Deposits
There is hardly a car enthusiast who does not know that black carbon deposits on spark plugs are a very bad “symptom” that requires diagnosis and urgent “treatment”. But how often do you hear talk about white carbon deposits in garages? But he is no less dangerous than black. Details are in the material of the AvtoVzglyad portal.

In the past, the spark plug was virtually the only informant that informed the car owner about the condition of the engine. I unscrewed it, looked at it and drew my own conclusions. Now everything is different: I came to the gas station, gave my hard-earned money, waited and went back. At first glance, it has become much simpler. But at the same time it is also riskier. After all, encountering a dishonest mechanic is, given the enormous number of services, a piece of cake.

So, to protect your wallet from unnecessary expenses, it makes sense to master some simple things yourself and return to basics – the same spark plugs. Let’s say you know something about black carbon. What about white? It is much more dangerous, at least because it usually signals much more serious “diseases”. Let’s find out which ones exactly.

The first and most harmless is the problem with the ignition itself: the spark occurs too early or too late. But in modern cars this is rare, because the moment of ignition is strictly controlled by the system using sensors. And if something goes wrong, the computer will certainly notify the driver – with an error message on the dashboard.

The second possible reason is related to a violation of the temperature regime in which the engine operates: overheating, operation in the upper limits. This is accompanied by wear in the cylinders, burning of gaskets, valves and even pistons. And as a result – “capital”. Check the antifreeze level and pay closer attention to the “thermometer” needle.

The third option is a problem with compression, a violation of the combustion process of the mixture. In this case, in addition to white carbon deposits on the spark plugs, you may notice a decrease in engine power and trim. If you postpone repairs, uneven operation of the engine will cause improper loading of the parts. Hello again, major renovation.

In summary, it may seem like all of these reasons are a big money grab. But do not despair in advance. The main thing is not to postpone solving the problem indefinitely. As soon as you notice a white deposit on the spark plugs, you should immediately send the car for diagnosis. And don’t forget that timely maintenance is the key to tomorrow when driving.
