Thanks for all the replies guys, been sat on a farm with no signal all night so just reading them now.
The only visible leak is the air conditioning as far as I can see. As far as pressure in the header tank, there is a slight bit of pressure after being parked up for 14 hours but I wouldn’t say it was major pressure and it’s not blowing water out of the cap. In almost sure it must be something to do with the water pump but not sure how or even if it’s possible to bleed the system?
