Car smoking

[TransAm91]

For the past 2 months or so, everytime i start my car white/grey smoke comes out of the exhaust. does this mean the valve seals are gone or could something else be wrong?

White smoke is usually coolant/water.
Blue smoke is oil.
Black smoke is fuel.

White smoke could also be condensation vaporizing from the exhaust when outside temperatures are low. Usually it's a sign that there is an internal coolant leak into the cylinder and is being burned off.
