Why are my spark plugs submerged in oil?

If your spark plugs are submerged in oil, it typically indicates a problem with the engine's seals or gaskets, such as a worn valve cover gasket or a damaged piston ring. Oil can leak into the combustion chamber, leading to poor engine performance and increased emissions. Additionally, it may result in misfires, rough idling, and difficulty starting the engine. It's essential to diagnose and address the underlying issue promptly to avoid further engine damage.
