Decoding the Secrets of Your Spark Plugs
Spark plugs can tell a story about what’s happening inside your engine. Each part of the spark plug, from the electrode to the ceramic insulator, can provide clues. Learning to interpret these signs allows for early diagnosis and prevents minor issues from escalating into major engine problems. For example, a sooty black deposit might indicate a rich fuel mixture, while a blistered, white insulator could signify overheating.
What Spark Plug Color Tells You
Different colors on your spark plugs indicate different problems. A light tan or grayish color signifies a healthy engine. However, other colors like black, white, or oily residues signal various problems, from a faulty fuel system to worn piston rings. Recognizing these colors is crucial for accurate diagnostics. For instance, a reddish-brown deposit might suggest the use of leaded fuel, which is rare in modern vehicles.
