smoko

hey just a quick question, whenever i start the car, no matter what time of the day it is, about 90% of the time it will always blow white smoke and when i rev it lot it blows black smoke, whats the go?

white smoke is oil buring, black smoke is to much fuel and needs a good service

[Boonz]

i thought white smoke was water in fuel, blue smoke was oil burning???

[Matty o]

ok what u mean good service, and how would it be burnin oil or more like how can i fix it?

[walesy]

black smoke might be an oxygen sensor too

Yep, white smoke is oil, black/brown smoke is fuel. White steam is water, then you have serious problems.

Like walesy said, could be an oxy sensor, quick easy fix. I'd take it for a service and see what the mechanic says. Could have oil leaking past valve seals or something like that causing the oil smoke.

mmmm, I don't like smoke. If it blows a lot of the white stuff a lot of the time then you may have dead piston rings/valve stem seals. I don't think it would be an oxygen sensor causing overfueling if he's just giving it revs at idle. Black smoke could also indicate unhappy injectors.

White Smoke could be Valves, Blue is Rings, Black is Fuel Mixture.

Not necessarily, rings can also make white smoke. Depends how much oil is getting through.
