What Causes Spark Plugs To Turn Black
A spark plug turning black can be a sign of several issues. Often, it means the engine is running too rich, with too much fuel and not enough air. This can cause carbon deposits to build up on the plug.
Another reason could be oil leaking into the combustion chamber. This can happen if there are worn piston rings or valve seals. A dirty air filter can also lead to black spark plugs. It restricts airflow, causing a rich fuel mixture.
In colder weather, short trips might not let the engine warm up fully, leading to incomplete combustion and black plugs. Regular maintenance can help prevent these issues.
