Hi everyone, just after a little help. Whenever I drive my car and give it a little boost up the motorway over time my car shoots a lot of the coolant out of what I can only see is either the rad cap or expansion tank. Day to day driving around town it's perfect, it's just when I go on the motorway for around 30 minutes if not less. It's running at 1 bar of boost and the only thing I can think is maybe the head is lifting under long duration of boost or the turbo (being water cooled) is heating the coolant too much. Is it possible to bypass the water lines to the turbo without it affecting the turbo? Any advise would be greatly appreciated. Thanks.
