i hope you will get your problem solved here. :)

if its smoking thats a shorted system..if you feel safe with fixing it do so otherwise get rid of that deathtrap..

Pull the vacuum line of the transmission modulator valve. If there's oil in the line, the diaphragm in the modulator valve is cracked and engine vacuum is pulling trans fluid into the engine intakee

The white smoke is probably steam caused by coolant getting into the cylinder(s) either from a faulty head gasket, cracked cylinder head or cracked engine block. The loss of heat from the heater indicated that coolant was being lost..

Your heater core is leaking. if it was left disconnected the engine coolant would have come out immediately upon starting the engine the very first time..

TIme for an overhaul and rebuild or a new engine. The rings and seals are shot. This is not going to be cheap. IF you keep driving it, there is an outstanding chance that you will seize the engine

Water vapor coming out of the exhaust at initial start-up is normal; that is condensation that collects when the engine is not running. White smoke at start-up depends on a couple of things. Tell me, where do you live? When the weather is very cold, all engines will emit steam (white smoke) when they are first running; this stops after the engine has been running a while and is warm.

In short, if this is only happening at first start of the morning and goes away over time, there is nothing wrong.

If, however, the "white smoke" continues and never stops, you may have a blown head gasket.

What car , and year and engine? What color smoke?

hey
there are couple of smoke type.blue smoke is oil, black smoke is fuel, and white smoke is water, if it clears after starting and running a few minutes it's probably your valve guide seals leaking oil down on top of your pistons, causing it to smoke until burned off and foul your plugs.
