Leaking spark plug hole leaking
2005, 145k miles, 50k on current engine, plugs and coils changed 10k miles ago, engine premixed from day one.
I noticed this morning that the leading spark plug hole on the front rotor is leaking. It's not a fast leak, since I don't see any drip while the car sits or is running at idle, but it's definitely happening. The area looks a lot like the side of a piston engine does when the valve cover leaks. Spark plug is properly torqued so it should not be leaking around it, and even so I wouldn't think there would be enough crank case oil sitting in there to leak since the car is daily driven. I have asked around and looked on several rotary sites but haven't seen anyone report an issue like this. My concern/fear is that the housing is cracked inside the spark plug hole.... Anyone have any thoughts on this?

You gonna eat that?

No experience with this, but are you sure it's coming from the hole itself and not from around the ceramic part of the plug?

This is the best I can do right now since I'm at work, I plan on taking the wheel off and looking closer when I get home tonight. You can see the black stain under the plug though, it's rather distinct even with this crappy picture
