FINALLY!!!!!!!!!!!!!
after a week of fucking about i got someone to have a look as it was doing my nut. Bit of an odd one, and im sure a few tech heads will have some pisstaking comeents but!!!!!!!!!!!
Where i had to disconnect the turbo water feed due to breaking the pipe, i blocked off the outlet on the stat housing, and the return inlet on the header tank, now for some bizzare reason thats what was causing the problem!!! As a temp measure ive got a pipe coming off the stat housing and going to the header tank till i fix the turbo pipe, but as soon as i did that water cirulated/cooled and we have life!!!!!!!!!!!!!
Obvoiusly its down to some sort of pressure related thing, so any tech heads care to share some thoughts?!
