It is really inconsistent, though so is my driving. sometimes 200 -300 miles. sometimes less. But when I drive it i check constantly. I have a wet area between intake and heads... but I dont think I have coolant getting into the combustion chambers (exhaust doesnt smell like it) I replaced my head gaskets roughly 4 months ago. heater core is clogged but not leaking.
The area thats "wet" looks more like oil and I noticed it when I replaced my lower intake with a used one that was not checked in any way other than visually during cleaning.

The amount of measurable coolant loss is small, maybe Ill drive from Milwaukee to chicago and the next day, Ill look in the overflow tank and its near the bottom when I left It may have been higher and after driving it is higher (but maybe not with expansion)
