Well all back togther and running lovely. Will upload pictures either today or tomorrow when i can get my phone to conect to my pc. Strangley there is still pressure at the air filter on tick over, raise the revs even only 100rpms and its gone. head was pressure tested and came back fine,all valves were sealing well so i'm alittle stuck as to where to look next. Bleeding the coolant system was a pain a friend of mine used a vacum bleed in the end, two seconds and all the air was out
