Has anyone tried a piston soak to reduce oil consumption? I've heard of people with other cars pouring Berryman B12 down the spark plug holes and letting it soak for a while and having great results. Anyone tried something similar?

With no spark plug holes on the diesel D4, how does on get to the bores to put the liquid down?
