Car: 2010 wrx, 4k on the clock. Properly broken in.
Issue: The day I got the car and drove it from the dealership after the first drive to the house I parked it for about a day, the next day when I started it up it blew a good ammount of white smoke from the exhaust, it would kind of just poof out, then nothing, car ran just fine. It didn't do it for prolly another 3 days, then again, on start up it blew the white smoke, and it went away, no weird idle no funny noises, car ran fine. Fast forward 3 months after I get back from Iraq. Car was parked for the entire time, turned over once a week, no smoke the entire time.
I get back from deployment, pick up the car, drive it contantly everyday and never saw the white smoke again, untill today. Started it up this afternoon mid day and it blew the smoke, it's not a constant stream, just a big poof and its gone.
Any ideas? Car is obviously still under factory warranty so i'll be taking it in this week, but if any one knows what it might be I can go in with some knowladge to the dealership.
Thanks in advance!
