I have an 09 WRX hatch that I just hit 1,000 miles with. For the past couple days, when I accelerate, sometimes a BIG cloud of white smoke comes out under hard acceleration (the motor is at or very near optimal temperature).
I'm in Michigan now, and I've lived in Florida for the past 4 years, so I don't know if this is just due to the cold weather or what...but it seems to go away after it does it once or twice.
I know all the possible symptoms of this, but I highly doubt my ring seals are bad or have a blown gasket, so...just looking for some experienced cold weather people to chime in on this...lol
Just an FYI: I did do an oil change yesterday (5W-30)
