Normal or Bad head gasket

I noticed today that the radiator is constantly cycling water through the overflow container at a high rate.

pulled the radiator cap and started the engine and had a tremendous amount of pressure pushing coolant back out of the radiator.

I know this is a sign of a bad head gasket or a cracked block, but I would think with this much pressure I would have some overheating which I dont.

Is this an issue like I am thinking it is, or am I not understanding something that is different about the titan cooling system.

I just got the truck used. and it had some engine problems that were hidden from me at the dealer. Is this another to add to the list, or is this normal?

Pretty positive the way the coolant system on our titans are that they will push fluid out of the radiator cap w/ engine running. Surely someone will correct me if I'm wrong.

As recommended fill your overflow to mark and pull your truck on a decent angle turn the heat on max and defrost with the cap on the overflow cracked a little and then tighten and you should be good to go.

Is it using coolant, oil look suspect or throwing smoke?
I have bad valve seals. But after that smoke cleared yesterday there was a faint smoke that looked more like coolant than oil. that is what made me check. and then the back flow had me worried.

it is not using coolant or overheating. but when I bought the truck some things were hidden from me and it does have some mechanical issues. So I am skeptical when something happens that I am not used too.

Thanks for everyones replies, it makes me feel better to know that it is normal.
