What are the hazards of spark plug leakage?

The hazards of spark plug leakage are: causing engine weakness, unstable idle speed, easy stalling at high speed, and even engine failure to start, which may seriously lead to spark plug failure and engine damage. The spark plug is an important component of the vehicle's ignition system and one of the vulnerable parts of a gasoline engine, playing a crucial role in the operation of the engine. It is recommended to regularly inspect and maintain it to ensure driving safety. The spark plug can introduce high voltage into the combustion chamber and generate a spark by jumping across the electrode gap, thereby igniting the combustible mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell.
As someone who frequently tinkers with car repairs, a spark plug leak issue can range from minor to serious, with quite a few potential hazards. First, it reduces the engine's compression efficiency because the combustion chamber loses its seal, allowing pressure to escape. The consequences? The car's power noticeably drops—struggling on inclines, sluggish acceleration, and fuel consumption skyrockets, costing extra on long trips. Second, the leak can cause irregular ignition, potentially raising engine temperature. If not addressed promptly, even the cylinder head could be damaged. Over time, emissions may exceed standards, failing environmental tests. Third, safety risks increase, especially on highways—sudden engine stalling or power loss multiplies the danger. So, whenever I notice unusual vibrations or noises, my first move is to check the spark plug seals. Replacing them with new ones isn’t costly. Regular maintenance is key—don’t wait for a major breakdown to regret it.
