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
Blue smoke is burning oil.Blue smoke is burning oil.
your truck blue smoke when it burns oil, or transmission fluid.
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.
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.
You may have blow a seal. This would cause oil to enter the combustion cylinder and cause blue smoke. Or the over fill could have cause oil to get in there and it will not smoke until it reaches the flash point (the point in wich it berns).
It is caused by oil getting into the combustion chamber and burning off
blue smoke is caused by burning of oil, oil can get into the combustion chamber through the oil and piston rings and or the valve guides would be the most likely.
Blue smoke is caused by engine oil being burnt by the engine.
Blue exhaust smoke is burning oil.
Blue smoke can be caused by a blown head gasket. . Blue is oil being burned in the engine.
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
The blue smoke is blow by on start up. The piston rings are still cold and when they start to get older, they take a few moments to warm up and expand to create a good seal and stop the escaping oil. It is pretty common when cars get up in the years and is not a huge issue.
Yes, can leak oil causing blue smoke
Yes, but so would really worn valve stems or guides. Either case, you gotta take the head(s) off, then do both! Head gasket(s) and a valve job.
Hi there,blue smoke on a diesel motor is normally fuel,and the smell will be unburn diesel,rough start and heavy smoke that will disapear as the engine getshot.
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.
