Had oil in spark plug chamber this from a bad spark plug

My car has 15000 miles.
My car has an automatic transmission.

Hello. Thanks for writing in. Oil in the spark plug wells is typically due to a failed gasket or o-ring. It can be a sign of more serious engine damage related to a failing valve or worn piston ring. You will want to try this simple fixes first, which would include replacing the gasket or o-ring (whichever your vehicle is equipped with). After that if the problem continues, you will want to proceed with further testing. This may include a compression test. The only way to tell is from further investigation, and a process of elimination. It may be beneficial to change all of the O-rings and spark plugs on the vehicle at the same time, if you are in a position to be able to do so. This keeps the wear and tear on the engine consistent, and ishe thought to help prolong the life of the vehicle. Start by replacing the spark plugs and O-rings.
