Hey everyone. Like the title says, I have a disappearing coolant issue. No visible leaks anywhere and temp gauge is reading perfect. Seems to only dissipate when I drive. Anyone have any ideas? A little background for those unfamiliar with my car...fresh crank, headgasket, thrust washers, front and rear main, all done march of this year. Car smokes for a few seconds on cold startup only. Blue smoke. 80k original miles

Don't know how to pressure test the 7m, but I will check and see if oil is mixing with the coolant.

hows the elbows of death? sounds like a pinhole leak near the manifold, and its not leaking to the ground as it evaporates on the hot manifold

Also check the lines from the radiator to the overflow tank. If those get a small hole in them, they'll push coolant out as the engine gets hot, and suck air back in as it cools off. Don't forget the pickup line in the overflow itself.
