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.

Black smoke would be unburned fuel: fuel injection problem. White smoke in the morning may be normal condensation. White smoke all the time would be blown head gasket (exhaust would smell sweet like burning coolant) Blue-white smoke would be oil burning...bad valve guides, piston rings, excessive blowby, etc. Black smoke = too much fuel in the mixture or not enough air. Check air filter or possibly a stuck injector. Blue or grey smoke = burning oil and indicates damage inside the engine or possibly a faulty vacuum modulator in a transmission that sucks transmission oil. White smoke = water vapor in the form of condensate. It's normal while the engine and/or the air is cold.
