Oil on spark plug..

Changed plugs last night and the # 3 cylinder had what appeared to be oil on it.

The one on right.

What should I look for?

First thing I'd do is pull the throttle body off and see if you have oil in the intake....if so I'd put a catch can on the car, run it for a while then check the plugs again

I agree with the catch can but I would also pull a valve cover and see if I could see the valve seal on that cylinder. I had a valve spring break and it shredded a seal. It burned quite a bit of oil until I found it though.

Yeah, if you have more then a thin film of oil in the intake I'd order a CC and pull the intake to clean it along with the intake ports on the heads. It might also be a bad valve seal on #3.
