ok so an unfortunate event took place on friday while I was in my wife's st on the way back home. Coming down the motorway a huge plume of blue/black smoke came out the back like a smoke screen. Managed to get to the services with no power at all as I was going into a space it completely shut off. Anyway got home and stripped it down a little to see what I could find. Loads of oil at front and the oil filter housing is melted a tad as can be seen in the 3rd picture. Theres oil in the inlet manifold and also can see small metal particles (looks like glitter) in the filter. So the next thing is check the turbo and check some other parts.
