![]() ![]() Kindly note that you would also change the current spark plug since the oil would saturate it and make it unsuitable.įailed Piston Compression Rings: Above and beneath the piston are piston rings that prevent oil flow into the car’s combustion chambers. ![]() Hence, the need for a swift action to prevent further issues. Nevertheless, they start to wear out with time, and once damaged, oil can leak into the spark plug well. These seals work effectively, acting as a cover for the spark plug well. Thus, you may soon notice some leakages, which may allow oil to enter the spark plug well.įaulty O-Rings: If you’ve handled your spark plugs regularly, you will notice the O-ring seals beneath the spark plug tubes. Such failure becomes more pronounced with the engine’s high temperature, and as such, the valve cover gasket starts appearing brittle. Nevertheless, there lie gaskets between the valve cover and the engine, and with time they tend to fail. Worn-Out Valve Cover Gasket: After a look at your car’s engine, you will notice a metal cover on the engine, known as the “valve cover.” This seal is designed to prevent possible leakages from the vehicle’s engine. There are five major reasons why you find oil on spark plug wells, and they include: However, the oil should not reach the spark plug well, as it can cause some severe issues. The oil moves with the oil pump’s aid, traveling down to the oil filter before it reaches other parts. Whereas oil in the engine works well for the moving parts, reducing the friction between them.Įngines store the oil in the oil pan – it can hold six quarts of oil. But what happens when you find oil on the bottom of the spark plug? Well, this issue involves two distinct systems the spark plug system and the lubrication system.īoth work well for the engine, as the spark plug ignites energy in the combustion chamber containing the fuel/air mixture. When your spark plug is in good condition, the car’s ignition should run optimally, and you shouldn’t face any hassles. There are various causes of oil in the spark plug well, and you can look out for some common symptoms and quick fixes. Nevertheless, there shouldn’t be any leakages that result in oil seeping through the plug well, as it can hinder the vehicle’s functionality. In fact, an insufficient supply of oil can cause serious friction and engine overheating. Similarly, oil is crucial for the smooth running of the car’s moving parts, acting as a lubricant. When it comes to the ignition of vehicles that run on gasoline, spark plugs are essential. Without swift action on fixing this issue, there may be some engine problems. When such a thing occurs, the spark plug o ring is faulty, and can no longer keep the plug well sealed. The presence of oil in the spark plug well is one issue that raises some concerns amongst car owners.
