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.
burning oil = blue smoke
valve guides and oil rings are most likely worn but a pcv valve can be stuck and blow blue smoke
your truck blue smoke when it burns oil, or transmission fluid.
Blue smoke is burning oil.Blue smoke is burning oil.
Stuck or broken oil rings can cause blue smoke.
My guess would be bad valve seals and/or worn valve guides.
blue smoke can be caused by sticking valves or burnt rings
vtecs do blow blue smoke when the valve stem seals are worn and the piston rings are worn alsoits verycommon in dohc vtec engines
White smoke = Coolant leak, head gasket is the likely culprit. Blue smoke = Engine burning oil. Black smoke = Engine running too rich, wasting fuel.
It is caused by oil getting into the combustion chamber and burning off
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
