can turbo cause coolant loss/
I have never heard of a cooled turbo so I don't think there is any connection between your turbo and the coolant loss. Are you getting coolant in the engine oil or oil in the coolant?
White smoke from the exhaust?
no white smoke and turbo does have a coolant system
no water in oil and no oil in water rad has pressure when running but coolant loss is very bad.
I stand corrected on the turbo cooling but if coolant was getting into the exhaust you would have white smoke (water vapor) coming from the exhaust.
