blue smoke is usually burning oil
white smoke is steam
black smoke is un burnt hydro carbons

he oil can get into the combustion chambers by lots of was incl#:
failing head gasket
worn rings

Its probably going to be something like the valve stem seals or piston rings.
Unless it's getting a lot of oil through the breather, which isn't very likely.
What are the plugs like ? Does it use much oil ?

the plugs are fine just a light creamy brown colour. And the car doesn't burn hardly any oil. I think it was just because i was ragging it and i use petrol additives which was probably burning off, thanks for the advice though.
