Right, where do i start......

i have a 2wd saph cossie, 200 block greens and standard t3. usualy, when it comes on boost it gets a bit smoky but it always tends to be more of an overfueling smoke than oil. but today, i was giving it abit of stick on the local A road, came to a set of lights and it was fine, drove on normaly for about a mile where i had to stop for another set of lights then i saw it, plumes and plumes of blue oily smoke and it didnt clear until i started driving ..........

what would this be ? at first i thought the turbo but there is no oil in the turbo hoses or the intercooler.

any help would be greatfully recieved as i need to drive it to work for the next couple of weeks



cheers in advance !
