Good news that you are not suffering from water loss
Shifting air out engines can be quite difficult - my pinto did not not fully bleed itself until I actually took it for a drive.
In terms of 'white smoke' it sounds perfectly normal to me, particularly if the weather is a bit cold. If I start mine at the moment it will blow 'white smoke' for 5-10 minutes. It is only condensation and once the exhaust is hot it will stop.
