My 955 turbo has consumed nearly 10L of coolant in the past 40 days. No apparent exterior leak (haven't opened up engine covers yet). White smoke exhaust upon cool-cold start up, tubes are done. Cooling system seems pressurized when I open reservoir cap. Apart from head gasket potential are there any other possibilities? Through intake somehow? Through turbos? Doesn't overheat. Help please
