spark plugs leaking?

i've done a search on this and I get flooding, and coolant leaks. basically here's what I'm finding. the area around the lower plug on first rotor, and both plugs on the second rotor are wet. I puilled the trailing plug from the second rotor and it was wet with the oil fuel mix. the only one that doesn't have any type moisture its the trailing plug on the first rotor. I've seen this talked about before and for the life of me can't remember it. the car runs fine, the plugs are less than a year old, regular oil changes, had an injection cleaning service done last spring. its not spewing fuel or anything just wondering why 3 plugs have moisture and the 4th doesn't. course any help to solve this would be nice too. thanks in advance

What color are the plug tips, and how new/old are they?

Are you certain it's not an external leak. I find it hard to believe if the plugs are firing properly you'd see any "oil/fuel" wetness on the plugs when removed, let alone on the outside of the housings.

well there's no stuttering, when I drive, nothing to give me any reason that they aren't firing. she has over 150K miles on her and still runs strong. in fact the only problem I've really had was tranny but I've driven it hard so that's my fault.

the fuel lines are above where the spark plugs are... have you double checked them to make sure they are on properly and not cracked?

there desn't appear to be any leaks along the fuel rails or hoses. I just think its wierd to see moisture around 3 of the plugs but not the tailing plug on the front rotor. I'm gonna try to clean the area as best I can today and see what happens.
