    I am adding water every 2-3 days to my radiator. I can tell when it gets low because the heater works and the temp skyrockets when an airbubble surrounds the temp sensor.

    I have no visible leaks and I don't smell burning antifreeze. The oil is not milky and everything else works great

    SOOOOO... Where the heck is the water going?

    Your leak might in the fins and tubes of the radiator core, and evaporating before there's enough to drip.

    Replaced the cap with a pressure release cap to make refilling easier. AND... replaced the overflow reservoir cap because the rubber inner grommet went missing... Water still disappearing... Dangit

    Ya know, I just thought of something. I disconnected the rear heat because it intruded in the cargo area too much. I need to check all those hoses and make sure that my "bolt&hose clamp" heater hose sealing system is still functioning properly.

    I was loosing water and it was coming out of the weep hole on the waterpump. No visible leaks anywhere I noticed my waterpump shaft was not tight as it wobbled when the engine was running. I replaced it and no problems

    Could be the intake front passage. Gasket may be bad and you're ingesting it in either #1 or 2 cylinder.

    I kept the heater core just incase I decide to put it back in more out of the way than the original installation.
