Default White smoke!?!

me and my buddy raced last night and he told me that he saw some white smoke coming out of the exhaust...and i noticed the other day that i have some kinda fluid being spit out of the passenger exhaust, there is not much smoke coming out, its just every once in a while it will spit some out.....is this just condensation in the exhaust??

or do you think there is oil in my PCV system??

white smoke is usually coolant.

check and monitor the levels of your fluids to see if any of them go down over time.

As a precautionary measure I'd go ahead and change your oil as soon as possible to see if there's any coolant in it. If there is you will be able to see it pretty easily since oil and coolant do not mix. Also check your oil fill cap to see if there is any white foam on it after you drive it. Usually white smoke means coolant is getting burnt, for me it meant a headgasket was on the way out. If the white smoke was pretty visible that's usually not a good sign.

I have the same problem going on now. I only see smoke at WOT. I have a set of ls6 heads that I am getting ready to ship out and get them worked over. I hope that it is only the head gasket in my case, as I am not made of money.

If coolent is getting in the oil will it look like oil in water? I am changing it this weekend.
