so im new here on this forum...im having a crazy odd misfire that im getting super annoyed by.i pulled out my plugs they were all clean except for #1 spark plug that is covered in oil on the bottom of the plug what could this be??valve seals??smokes only a lil at idle sometimes after the car warms up

 

so nobody has an idea of how there being covered with oil and causing a misfire??

 

It could be a number of things.It could be your piston rings how many miles do you have on her?
