Sounds like it might be the coolant tank cap,this is a common problem it does not keep the coolant under pressure and boils over in tank.
Replace it with a genuine one,I always carry a spare as they only last a year or so.

thanks for the speedy reply will try this and let you know

Get a couple as it isn't uncommon for a brand new cap to be faulty either!

will do thanks

new header tank cap fitted, cost £6,20 job done. Thought i was going to have to fit a new head gasket. THANK YOU
