Perhaps i'm off base, but a leaking headgasket will allow exhaust fumes to be compressed into the cooling system. A chemical check of the air bubbles can be performed to verify.

So prehaps its my headgasket then is why the airbubbles are running threw the raditor

The headgasket when breached can allow exhaust fumes to be compressed into the cooling system.
The headgasket is between the cylinder head and the engine block (on top of the cylinders). There are coolant passages nearby that can be exposed to the compression of the cylinders if the gaskets fails there.
The coolant continues to circulate carrying the air bubbles until the surface.
