hinomoto E2304 coolant

[cajun Dan]

Has any one had a problem with coolant loss from air in the radiator?
Acts like blown head gasket,runs cool for about an hour,till most
of coolant is blown out. Can see bubbles in over flow tank,no water
in the oil,tried flush and bars leak no go.no external leaks.
priced a head gasket 170dollars would do it but lot of work if im
wrong on my asumptions for this problem,have heard possible to leak air from
injector seats? any suggestion?

Possibly bad rad cap, but probably blown head gasket.
