Oil on Spark Plug threads and Tips..., Have pics of problem... Options

[Princess_Sparco]

When i first bought the car 2 years ago and changed the plugs. I noticed that there was some oil on the tip of 2 of the spark plugs. It didn't bother me too much then. A year later i changed the plugs again and there was oil on 2 of the plugs. On the thread and on the ground tips. Just recently I changed the spark plugs again, but this time, the same two plugs were dripping oil. the threads and the ground tip was covered in oil.

can anyone point me into a possible direction as to why this is happening? I originally thought it was the valve cover gasket (spark plug gromets) but wouldn't it leak oil on top of the spark plugs if that was the case? There's oil on the tip of the plugs which suggests to me that oil is leaking into the combustion chambers. I did a compression test awhile ago and the numbers aren't totally off. unfortunitely i dont' have those numbers anymore (lost them). if it helps you find my problem i can do another compression test.

its the valve cover gasket/spark plug tube seal. you see more oil on the 2 of them because you have a little puddle of oil down there and it gets all over the plug when you pull it, not because you have that much oil in the chamber. trust me, if there was THAT much oil in the combustion chamber you'd leave a trail of smoke like that doobie from history of the world part one.

also, the "oily stains" around the ceramic of the plug are just corona stains and are COMPLETELY NORMAL AND HARMLESS. the electric field around the plug attracts oil/dirt and the heat stains it into the ceramic like tar stains in teeth.

additionally it looks like you lost part of your spark plug wire on the right most sparkplug.
