Losing coolant?

[BlackMetal]

Seems like I'm losing coolant. Overflow is always at the bottom after a drive. Oil seems clean on the dipstick. No visible leaks. Didn't do anything to blow a HG. No smoke in the exhaust, no smell. This is after changing the intake gasket for a vacuum leak. Don't think I could have done anything wrong. Used RTV around the water jackets. Followed the torque pattern for the intake bolts.

First couple days I just assumed the cooling system was burping out some major air and the level was dropping. Little worried at this point though.

If you can't find where it's disappearing to, maybe you had a few air pockets that are working their way out ?

That's what I'm hoping. Not only did I drain the radiator but I jacked up the rear of the car to let more coolant pour out from the intake and block before changing the gasket, so maybe it's just taking longer to purge the air.

I've only driven it a handful of times so I'm hoping that this still is just a case of air pockets.
