Hi, I have the same problem with my 06. Pulled the plugs out and they were totally oil soaked. I think it might be more than a gasket, I'm thinking valve guides or seals. I just put new plugs in it and I will check it once a week, when they get soaked again I will take it to the dealer ( I bought an extended warrenty) I will report my findings later. This should not be happening at 45000 miles!!!!!!!!!
