There are 2 separate problems here.
1. Oil in plug seal. There is a leak in the plug seals under the valve cover and/or O rings under the rocker carriers. This would result in oil getting to the spark plugs. The seals and/or O rings have to be replaced to rectify.
2. Oil is getting into the cylinders and the most common areas would be via the valve seals. Standard procedure is to remove the heads to to perform a valve job to solve the problem.
