We have found the issue, there were no leaks, it was the coolant surge tank we were using, it was too small and when cold we were filling it up to the line we put on the sight tube so when the engine got hot the coolant expanded and filled the surge tank and then as more entered it the overflow worked and let it out to atmosphere, so next time it was checked the coolant had cooled and flowed back into the radiator and the level now showed below the line we put on the sight tube. we only had a 1 ltr surge tank where as the stock RW surge tank holds 3 ltrs, and when it is check via the dip the finger there is 2 ltrs in it.
We are however going to take this opportunity to replace the fire rings with the later solid head gasket and the base gasket as well, we will machine off the fire ring face.
