A car blows blue smoke usually when it is burning oil most of the time it is a burnt valve. Which requires pulling the head and machining it followed by reseeding the valve.
= blue smoke is caused by oil burning more likely to be worn out valve stem seals than a burnt valve if valve is burnt, you will get backfiring in engine seals just allow oil to run down valve stems into combustion chamber a good mechanic will have a special tool to hold valves in posotion with out removing the heads a lot less costly than removing heads
--As I understand it, the blue color is not from burning oil, but from oil failing to burn. The oil forms tiny droplets that make the smoke blue just as the sky or sea. In any case, your main suspects will be valve guide seals, piston rings, and turbocharger.
