Took one of my stock spark plugs out and there was oil all around the threads of it? I have 25,000 miles on it no mods its an 09....am i just being paranoid or is my engine f@$%ed!

 

Probably a valve cover leak? is it the back corner plug hole?

 

No its front one...i only checked one but seeing that one was enough for me...I looked all around the valve covers...no leaks....I did run full synth. for the first 10000 miles im wonder if the thin stuff leaked thru.....this oil looks pretty fresh though
