How do you fix oil on spark plugs?
Additionally, should a spark plug have oil on it?
The reality is the oil isn't really on your spark plug but it's pooled up in the bottom of the tube the spark plug sits in so when you pull the plug out it gets covered in the pooled up oil. ... Replace the tube seal requires removing the valve cover and changing the valve cover gasket as well as the spark plug tube seals.
- The engine requires repeated attempts to start or the engine won't start at all.
- The engine misfires or runs rough.

When a spark plug well fills with oil, it means that the O-ring that seals the well to keep out oil and debris has deteriorated and started to leak. Although the leak can sometimes be fixed by tightening the valve cover bolts, more often than not the valve cover gasket and well seals will need to be replaced.
Why is my spark plug wet with oil?
Oil pooled in the spark plug well indicates a leaking component (e.g., tube seal) allowing oil to enter the well and contaminate the plug. The corresponding ignition coil (or spark plug wire) will also be wet.
