Does EA111 Spark Plug Oil Leak Need Repair?

[OCecilia]

Oil leakage at the spark plug position requires timely repair, as prolonged oil leakage can accelerate spark plug aging, reduce ignition strength, and in severe cases, damage the rubber insulation of the ignition coil due to oil immersion. Below are relevant details about spark plugs: 1. Description one: The spark plug, commonly known as the 'fire mouth,' functions to release the high-voltage pulse electricity delivered by the high-voltage wire, breaking down the air between the two electrodes to generate an electric spark that ignites the air-fuel mixture in the cylinder. 2. Description two: Main types include standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. 3. Description three: Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition cables, but in the past decade, most car engines have switched to direct connection between the ignition coil and spark plug. The operating voltage of a spark plug is at least 10,000V, with high voltage generated by the ignition coil from 12V electricity and then transmitted to the spark plug.
