car smokes at start up

03-20-2008, 04:29 PM
I just had a built b18 motor put in my 1992 integra , it has white smoke coming out the exhaust at start up and sometimes when im driving , he put oil stabilizer in it and some octane booster in the gas tank before i took off , car runs great but im wondering what the smoke is . Can anyone help ?

typically white smoke is oil burning blue smoke is too much fuel
dont misjudge white smoke with white steam as white steam is water

White Smoke = Coolant

Blue Smoke = Oil

Black Smoke = Fuel

condensation can accumulate in the exhaust which will blow white steam as it gets burned off.... does it go away after driving for a while??

i dont know why people always try and say color is the best tell for a smoking car. its not. smell is. if your burning oil or coolant, you will be able to tell by its smell. oil smells like burning oil/plastic/ect. since its all petroleum product, and coolant has a very sweet smell to it.
