Did a track day at Donnington the other evening and when changing gear got a noticeable puff of blue smoke out the back, asked my brother on the pitwall to watch and see if it was like it when on boost but he said only on the gearchange, anything to worry about? Car is a series1 and i must admit to topping the oil up before going on track to just above the max on the dipstick.
