Are the plugs black/ashy from burnt oil?

Oil can only get into the combustion chamber so many ways. Rings, guides, or the charge pipe/intake manifold (blow-by or turbo).
You're thinking of the OP...last time I had my IC and charge pipe off it was oily...
Do you have an oil catch can and an upgraded PCV valve?
