Default White smoke??

White smoke has been belowing out of my exhuast for like a week now, someone said something about it at firt and I thought it was just moisture. Today after my oil change I noticed it. It's mostly at idle and goes away during a free rev, either that or there is so little that it just blows it out of sight if you know what I mean. What is this and how do I fix it?
-Thanks

I've heard of this being burnt coolant fumes. It's happened to me once before, but only out of my driverside pipe? That was RIGHT before I blew my spark plug. I doubt it has anything to do with it, but check if your plugs are tight and functioning just in case.

White smoke is coolant. Get down and smell it if it smells sweet then its coolant and probably a head gasket.

Not necessarily, but most of the time! You can have blow by and to most it appears "white" unless you get a real good look at it or get up against a white car to see the blue. If it's not coolant (head gasket or head prblem) then it's most likely a valve stem seal! They run like $30 at local parts store and take about 5 hours to do! You can still have super high compresion and have either ring or valve seal problems also. You really need to do a leak down test to properly diagnos the sitiation

If there aren't any bubbles in the radiator (meaning compression from engine getting into coolant passageways, read bad head gasket) then it could also be a bad intake gasket. The intake has coolant runners in it. If one of these just corrodes through or get through the gasket, you'll suck coolant into the intake then into your engine.
