Hi all , iv got a 1998 Freelander Xei and iv recently had new modded head gasket , new head , pistons , cam kit but after a few weeks the water keeps disapearing but there is no water on floor and cant see any leaks , the only other thing i can say is after a 90 mile trip i got out of car and heard water , looked under to see it running out , lifted bonet and the rad filler cap was kinda boiling over ??? any ideas thanks , ( im a new landy owner ):doh:
