Default Signs of a cracked intake manifold?

Lately my 04 GT has had some white smoke coming out of the tailpipes when i first start it after it has sat over night and has some condisation but once it warms up it goes away and when i am sitting at a stop light it does the same thing after the engine has cooled down.I am really hoping it isn't the early signs of a head gasket problem since the car has only 48K.And i am not running cats on the exhaust either.Any advice would b greatly appreciated thanks

Completley normal, look into some physics material and you will see why. Ever notice how in the cold cars seem to puff white smoke for a long time? evaporation, temperature and theoxygen combining with carbon all do that.

dude my car was doing the exact same thing for the past two weeks and i couldnt figure out what it was until i noticed that one side of the exhaust smelled different. so i took a real close look into my engine bay on that same side and noticed coolant on top of my cam covers and fuel injectors. it looks like i blew the manifold gasket or may have cracked the manifold cant tell at the moment.

Take a flashlight and look for coolant pooling around the injectors or on top of the block.

Mine cracked at the thermostate housing and it caused coolant to pool up around the #5, 6, and 7 spark plug wells. It made some smoke come out the tail pipes but only when it made the plugs fail from being wet. Also if your car is only smoking in the morning or when its cool outside then that is normal.
