Volvo: 940se 91 turbo, head gasket, resevior

Question
I had a blow head gasket, the engine over heated twice in one day and the needle was begged. I replaced the head and all new gaskets. I am consuming some coolant (amount in resevior) after i drive 40 miles. I dont see it leaking anywhere on the engine (water pump, radirator) I looked all around got under and nothing. Im afraid that i may have ruined the seal on the turbo, will the turbo suck water out of the cooling cavities of the turbo. I should also get a diagnostics on the radiator to make sure the rebuilt head isnt cracked.  

Answer
Martin,
If the turbo was burning coolant you should see white smoke from the tail pipe. You will want to have some diagnostics done to see if there is a leak that is external and not real noticeable. Have the system pressured tested for leakage. Any coolant burned in the engine will result in white smoke from the tail pipe.
