I have a 1992 loyale that also suffered from "mysterious" coolant lose. The original owner sold it to me dirt cheap because someone told him it was the common subaru head gasket failure problem.
It compression tested great, ran strong and seemed fine except needing coolant top-offs on a reguilar basis.
Turns out the problem was a very small leak in one of the little coolant bypass hoses in the back of the engine. It was leaking so slowly that it evaporated right there on top of the engine instead of leaking onto the ground.
A coupel dollars worth of hose and some new clamps fixed the problem. That was 22,000 miles ago and no further coolant has been lost.
I hope you are as lucky as I was. It's worth checking, at least!
