What Specifically Causes Oil in the Spark Plug Well?

Before we discuss why this issue is pressing, let us take a quick refresher course on the function of the spark plug. The spark plug is responsible for igniting the mixture of air and gasoline in the combustion chamber of your vehicle.

However, these essential car parts also move heat out of the combustion chamber and into the cooling zone. This igniting process works thanks to the spark plug’s ability to create an electric reaction. 

Oil, on the other hand, works at lubricating the systems in a vehicle which prolongs their life and protects against things like dirt, dust, and debris. So how does oil get into the spark plug well? Typically through an oil leak.

As we mentioned, the most common way this malfunction occurs is through faulty gaskets. Gaskets lie between the oil cover and engine and thus become exposed to high temperatures.

In many cases, they can break down and fail over time and leak oil into the spark plug well. Similarly, o-rings (which lie at the bottom of the spark plug well) can also break down over time. This part works at blocking anything from entering the well, so when it falls apart, oil can get inside.  

A malfunctioning piston is a more serious issue since it can leak petroleum into all sections of the car. If you hear a rattling sound accompanied by a loss of power, then stop driving your vehicle immediately.  This issue can result in a severe engine fire.

We hope this article helped you find out why there is oil in spark plug well. Unless you are familiar with the internal systems of an automobile, we recommend taking your car into an auto shop to get an official diagnosis.

Good luck getting your vehicle back up and running!
