I drive a 2008 sti hatch and noticed today after I had switched the engine off that white smoke was coming out of my right exhaust. Prior to that I had revved the car and noticed some white smoke from my rear window. Is this anything to worry about? I always let the car idle for a minute before switch off.

 

prob just moisture bud. when the smoke is blue then worry! white smoke is usually water vapor or something along those lines. check coolant levels etc if it eases your mind or have someone look it over as there is the possibility of head gasket issues etc.

 

Many thanks mate. Started the car about an hour later and just the usual bit of start up smoke (when revving) from both exhausts. Very odd. Coolant levels seem fine so will just keep any eye on it for now.

 

Yes!!! Its just moisture....
