Default HELP! white smoke

Hey you guys thanks for all the help. Problem is solved now, it was just some turbo blowby I guess since the turbo is nearly brand new only a few hundred miles now and was just breaking in.

it just did it again after letting it sit for a little bit. Could that just be from the turbo?

White smoke usually means coolant is getting in the exhaust path. Leaking head gasket, or turbo. If it leaks in the cylinder overnight and you crank it, it will hydrolock and bend the rod on that cylinder.

If you try to start it and it seems to be a little tight or hard to turn over that usually means it has gotten coolant on the top of a piston and it is trying to compress it. If it's loosing coolant you will see coolant dissapear from the overflow tank.
They make a inexpensive coolant checker to check for gasses in the coolant.

If it hasen't done it anymore maybe it's ok.

White smoke usually means coolant, i.e. headgasket problems.
Bluish white means oil burning.
Get the tester for combustion gases in the coolant reservoir and it will tell you if you have headgasket on its way out.

Coolant and oil can both be white. The easiest way to tell the difference is by watching how long it "hangs around." Coolant will dissipate pretty quickly (seconds), unless it's very cold out. Oil on the other hand will linger. If there's not much wind, it will stay around the car for quite a while.

Had to bring this back up since I'm getting the white smoke out of my exhaust and it does dissipate quickly. This is a newly built motor with about 500 miles. So this tells me most likely a head gasket failure according to bluescoobywagon's description above. I haven't done a leak down test but will soon. I had some knock events, stumbling at about 5500 rpm on a base map and is what most likely caused this. Changed dino oil after a couple hundered miles and dark not translucent as the new oil looked. Hopefully it's only requires a head gasket change.
