I assumed it was supercharged because your sig says SSEi. Sorry, my bad. personally I don't see any easy way for oil to get threw the LIM gasket and into your cylinders. Only 2 ways for oil to get in there, threw the valve seals, and past the rings. Burning oil all the time suggests rings. Burning oil at the start up after sitting suggests valve seals.
As for the plugs, I still suggest a good copper plug simply because the price of a high end plug is a waste of money. There is no performance to be gained using those plugs.
