Can white smoke blow out threw the exhaust caused by a bad turbo or NO are their seals in the turbo to stop coolant from escaping or is that something different.

The turbine center housing of the turbo is water cooled and has a coolant passage, but it does not come into contact with any moving parts of the turbo, thus no seals for the coolant system in the turbo.
It's possible but very unlikely that there could be crack in the center section of the turo allowing coolant to get into the airstream, but that's the last place I would start looking if your getting white smoke.
How's you headgasket? Done a compression test and cooling system pressure test?

Oh ok than so what your saying is it is impossible for a turbo to blow white smoke.
Dead engine will kill turbo very quickly.

Hmmm good point i could do the same thing to the oil lines and see if the seal is poped to huh.
If you do that to the oil line, kiss your turbo goodbye.
Oil is critical for the turbo, much more so than coolant, running with the oil line disconnected to the turbo is not a good idea unless you can prevent the turbo from spinning somehow (ie. vice grips on the nut of the compressor wheel and the wastegate wired open).
The coolant going to the turbo is designed to reduce warranty claims and reduce the chance of oil coking in the turbo after it's shut off. The turbo will proabably survive for a while with no coolant as long as it's allowed to cool before shutting the engine down.
