    This is what Iím thinking. The overheating scenario created enough pressure to take the pipes out. They are VERY fragile at this point.

    The freeze plugs are probably more reliable than those hoses...

    Edit to add: the starter is where the chain is attached in the photo, above. There's that coolant hose that curves back towards the front in that area.
    Makes total sense.
    I'm gonna check with a radiator pressure pump and a snake camera

    Do I still have pressure on the cooling system even if I remove the intake manifold?

    Yes. They're independent systems. I recommend new intake manifold gaskets for reinstallation.

    Thanks
    I already bought the manifold gasket, cooling pipes on the side of the engine, throttle body gasket, oil separator hose, and planing on cleaning the idle valve and throttle body when I remove the manifold.

    Do you think I have to do something with the CCV?

    Exactly.

    Do I have to replace the CCV and all the hoses too?

    I would, personally. Especially if you donít have any record of them ever being replaced. Make sure you grab the cold weather package CCV. Iíve heard itís a little more robust.
