A lot of white smoke during start-up

[chito31]

When I start my car, I get a lot of white smoke coming out the back end. It usually goes away after driving about a minute, but it's an extremely amount of smoke the first few seconds. It is worst every morning after the car has been off over night.

Also, I had just replaced my cylinder head and all gaskets including replacing the water pump and timing belt, so it can't be a BHG. Can it possibly be the catalytic converter or other exhaust component? Or, it's only been a day since I changed the cylinder head, maybe I just need to let the car run a little more.

Any advice out there????

i maybe wrong but it could have sumthin 2 do wit the air/fuel mixture or somethin related to a sensor, just an idea since u said it's not ur head gasket
