The black smoke from start up?

[3rdcoastmrauder]

Has anyone found the exact reason for this to happen. I live in Sugar Land, Texas (near houston)(high humidity) and have never had it happen here, but I've got a friend who lives in huntsville (north of houston/south of dallas) (lower humidity than sugar land i believe) and it seems like it always happens their, even if it's not that cold out. Any speculations?

[sailsmen]

White smoke coolant leak or condensation in exhaust

Black smoke too much fuel

Blue Grey smoke oil, possibly valve guide/seal

Do a search.
