    hmm.. does your car shoot white smoke out the exhaust... and when it heats up does it start running like ass and misfiring?

    it's like the water doesn't run thru the engine it's weird, i have new waterpump, and it builds up a pressure of hot steamy air in the radiator

    sounds like what my car is going through.

    pull off your oil cap. look underneath it and look for anything that doesnt look like normal oil (creamy kinda green for mine). if so, thats a blown HG.

    the sweat smell is burning coolant. mine does that also, not visible but you can smell it. its a small leak.

    have u ever replaced the head gasket on the car???
    if u have the person who put it back together could have put it one backwards
    this could be closing some water jacket holes i have seen it happen a few times ppl think they can only go one way but nope there wrong and thats what happens

    This might sound stupid but try taking out the thermostat and running the car. If its stuck shut it might be building up pressure like that? I really dont know though, never heard of this kinda problem so im kinda BSing lol.

    so you're saying that when the car is on and running it'll be fine for a while, but then as it heats up the radiator and the hoses become full of steam rather then coolent?

    have you tried filling the system

    have you done a compression and leak down test? that should tell you pretty well.

    ALSO! LOOK UNDER YOUR OIL CAP! thats the easiest way to tell if you have coolant in your oil, which means a BHG.
