Small as it may be, this part is what supplies the spark for your engine to power your car. If left dirty, it can build up lots of dirt and oil. If this build-up continues over time, your engine can malfunction, causingcatalytic converter misfiring and damage to your precious car parts.

So, in this article, we will guide you on how to clean spark plug holes to ensure your car remains in top condition.

What Are Some Of The Negative Effects Of Dirty Spark Plug Holes?

Oil and dirt can get down to the well in several ways. The most common way is when there is a leaky or faulty valve cover gasket, which seeps oil down through the hole to the engine. A little bit of oil is not a cause for concern, but if a lot goes down the engine, it can lead to damage in the catalytic converter of the car and the plug. It can also lead to an issue known as the hydro locking of the engine. This is a situation where the engine is unable to compress the fluids present in the car, which could lead to severe damage to itself. There are also the worst-case scenarios, where spark plugs can corrode to the point where they break. The breakage could cause serious damage to your car and necessitate full-blown repairs. Hence, it is important to make sure you regularly clean it, or else you may have to replace a lot more for your car than just new cleaning materials.

  • You should start by disconnecting your car’s negative battery terminal and locating the spark plugs. There should be one coil/cable and one plug for each cylinder of your car.
  • The first thing you want to do is clean the surface of the plug with your air gun or any other tool that can do the same. Once that is done, disconnect the ignition coils one at a time. Then, loosen the part with a spark plug socket and unscrew it.
  • Now, all that’s left to do is cleaning the empty well with your air gun. This is the best way to remove all debris and oil. However, a rag or cloth wrapped around a screwdriver does a pretty good job too, if you’re left with that option. Just ensure you thoroughly wipe the well and use a carb cleaner to ensure the oil is removed.
  • Once this is done, clean the plugs thoroughly with your tools. Wire brushes and sandpapers work well for this.
