Just changed my spark plugs and 3 out 4 looked fine to me but the one of them had alot of oil on the threads. what can this be from? it was the sparkplug closes to the intercooler. i'm not sure what # that is.
thanks for your input. posting some pics....

swimmingly

From front to back on the car the cylinders are 1(front) - 4(back).

You might have a lot of oil blowby from your air oil separator. Pull one of the intercooler pipes and see if you have a lot of oil in there.

i do have a some oil in the intercooler pipe. and also it is cylinder #1(the one on the left in the pic of four) that had all the oil

Could it be anti-seize compound? I use it on my plugs and when I take them out, it looks like oil.

I suspect someone lubbed them up real good when they put them in.

Could be caused by a leaking cam carrier/cover gasket.

EDIT: Never mind...you don't have an S or S2....my solution doesn't make sense at all.

no, i changed the plugs about 10K miles ago and i didn't use any anti-seize

.....and you better watch out , because you are moving some air and those plugs are getting hot.........
