Exclamation Oil on spark Plug

I need some advice.

I just bought my first Camaro yesterday. It's a 1985 with a 2.8l v6. So I got it home and decided to change the plugs, fuel filter, oil change, etc. I am by no means an auotmotive mechanic. I fix aircraft and that's an entirely different monster. Here's what I ran into while changing the plugs. The middle plug on the passenger side (sorry not sure of numbering) was coated with oil. I have read that it could be a valve guide, piston ring or valve cover gasket causing this. Can anyone recommend the best way to find out what it is before I start tearing it apart? Could it be something else? It's just one plug hole, the others look just fine.

Re: Oil on spark Plug

Visually check the gasket intregity to make sure there are no leaks.
Drvr side from the front to rear 1, 3, 5
Pass side, 2, 4, 6.

Oil on electrodes could bea leaky valve stem seals, broken piston ring, or no spark going to the plug. Engine will run on 5 cylinders.

Change plugs, check to make sure spark is getting to the plug, fis what's broke, coul dbe a bad wire. Drive it for a couple days, then recheck spark plug for oil deposits. If depsoits return, could mean an overhaul or swapout of a 3.1L or 3.4L long block is forthcoming.
