    It isn't coolant (I know it "looks" white). Your valve seals are leaking. This is common for these motors. Mine leaked as well.

    There's really not enough information here to determine what's going on. If you pull the radiator cap, can you see any bubbles coming up through the radiator? That's a sure sign of a bad HG.

    Pull the plugs, are any of them particularly clean? If so, that cylinder may be the issue as water tends to steam clean the cylinders.
    Then, run a compression test.

    Or, yeah, just ignore any testing and throw parts at it. Your money.
    Yes, the PI(99-04 mustang) intake can be bolted on. Use PI gaskets and you'll have to put a couple of dabs of silicon in a key spot to seal correctly. You'll get a nice ~15hp bump in power to boot. Do a search and you'll find hundreds of write ups.
