water header tank Sprinter 311cdi

[cantona7mac]

Hi can anyone help PLEASE ! I'm using half a pint of water every 200 miles but for the life of me I cannot find a leak from any pipes and there is no water going into the engine (Sprinter 311cdi). Is it normal for the tank to be pressured up even when it hasn't been running, Any help would be great !
