Maybe it's not tight enough or stripped? Idk but I just tried to change mine and the one in the back on drivers side(far right by intake) was full of oil as well. I know they are old, probably original from 80k miles ago, and Idk why it would be full of oil either. I took off the upper intake collector to get to 5 of them but, the one opposite the oily one, far left in the back(passenger side) wasn't coming out without removing the lower intake manifold. So I changed out 5/6 of my plugs :)
