My ex plod now has 264k it's using about a litre of oil every 2k. Over the last week I've noticed when I stop for traffic lights and let the car idle while waiting thete seems to be puffs of blue white smoke that smell of burning oil. As soon as I acellerate away the smoking stops, I'm I right in thinking it could be seals on turbo on there way out? There is also a small weeping of oil on the outside of the turbo. Turbo was last replaced at 100k
