Oil all up in my spark plug!

Oil all up in my spark plug!
I just got a 1998 s70 (not sure which trim) and i just realized my #5 plug hole is almost full of oil. the others have a drop or two (dry) and the valve cover is puddled here and there.
I've read a few threads about this that say it could be my fill cap gasket, but there is no evidence of leakage from there. it's all dry around. Maybe the O ring at the bottom of the cam shaft base mount. I don't know because I've never been in this engine before.

I dont know about any treatment for the sparkplugs but I have a similar issue where I have oil on top of the engine, around the center spark plug well. it seems to be coming from the oil filler cap but I changed it to a new one and its still doing it sometimes.
I'm wondering if it's coming from the black plastic tubing(PCV) that comes along the same way, I doubt it's just spilled oil at this point.
Let me know how your situation goes after a clean up I've done the same.

Well, I cleaned it up off of the top and out of the plug well. After driving around for a couple of days, I can see there is no leaking from the cap, the pcv, or the plug itself.
However while cleaning and observing, I spotted a bolt thru the top seated in cheap sealant. I will post a pic when possible, but I think this means a breach in the liquid gasket. (possibly a crappy redo)
Anyway, part of this problem I'm sure is due to a clogged pcv system pushing too much pressure thru.
Feel free anyone to comment if I'm totally wrong.---I'm brand new to volvos and fairly in-experienced engines in general.
