Air bubbles in radiator!

[V8fleetside]

I got air bubbles in my radiator, moore speed moore bubbles.
I think there is a broken gasket somewhere.
Anybody knowing something about this?

A blown headgasket that is leaking compression into a coolant passage can cause this symptom.

you can get a test kit for the antifreeze that will tell you if there are hydrocarbons present (which indicate combustion gases entering the antifreeze.

I'm sure that any radiator shop would have the test, napa may also carry it.
