Re: leaking plugs
First, make sure you've got tapered seat plugs. If they're washer seat, they will leak. Second, figure out why you have oil in the chambers. Do a leakdown to see where it's coming from.

Re: leaking plugs
spark plugs dont hold oil in, well, they arent supposed to. You need to look at the cause of the oil. Is it coming from the outside or inside? Is it a valve cover leaking? Does the vehicle let out a puff of smoke when you start it?? It could be valve seals, valve guides, or rings. Could even be a leaking intake gasket. Vacuum and compression testing would probably be in order, if an obvious source cant be found.
