Hi Guys
Any ideas noticed a few days ago that my coolant level was low topped it up,checked again before going to goodwood and it was empty again and then when coming back it was empty again,and the same again this morning its taking about half a kettle of water to fill up,i have no water at all in the oil checked and checked again,its not wet around cap or any steam coming from that,have no leaks that i can see anywhere on the garage floor after parking up,checked inside incase heater matrix leaking etc and all carpets dry,car is driving absolutely fine all gauges showing there normal temperatures etc,had the car ticking over for about 15 mins this morning and couldnt see any leaks,waited till it cooled down and the level still the same, so presume it is only leaking when under pressure..... but any other ideas what to look for????????

Thanks very much!!!!!!!!!!!!
