So you want me to drill a hole in my closed system and create a weak point so that I can prevent something that hasn't happened yet? I think we should require coolant catch tanks on air cooled beetle too. There is no breather valve on the VW system. So there is no place to vent it from. To do so, would illegally modify the cooing system IMHO.
