Spark plugs: how to know when the engine is failing because of this part

Vehicles are designed to withstand high demands during operation, depending on their technical characteristics. In addition, these are “intelligent machines” that give signals when something is wrong, like a person when he is sick.

It is important to know identify these signs to prevent problems from getting worse. In addition, it is important to determine when this is normal or happens day to day, and when we are facing serious damage.

The powertrain must always be up to date in order to enjoy a quiet but above all safe driving experience. One of the most important parts for the overall health of a car is the spark plug, although it offers us a complete engine diagnosis when something goes wrong.

This detail is responsible generate a spark to ignite gasoline inside the cylinders, so they need to be constantly checked to know how everything is going.

Spark plugs speak for your engine

When these parts look like scale (usually white), it can cause the engine to misfire at high speeds or under load. This can happen when oil leaks through the piston rings.

Getting carbon on the ignition tip will cause starting problems, so it usually takes a few tries to get it right. In addition, performance on slow transfers will be significantly reduced.

On the other hand, if wet and black grease is present on the same tip, this will also cause the problems recently described.

Now, when you see a whitish or shiny porcelain insulator, you will feel the engine pounding, losing power when climbing a slope or when carrying heavy loads.

Fine grainy residues with burn marks on the electrodes and insulator surface can form after using low-octane gasoline, and constant knocking in the power unit can affect your engine.

The porcelain tip of the spark plug insulator can break or crack (probably due to thermal shock), resulting in very poor performance, visible throughout the entire rev range after failure.

Finally, oxidation of this part along with corrosion will cause problems with starting the engine, making extra efforts to provide power, but sooner or later it can fail.
