I have a '98 Outback with 74K, bubbles in overflow bottle, AF blown out overflow bottle on belt drives. Classic internal HG leak on the Phase 1 2.5; but at 74k? WTF? Towing insurance rules. Was told to "snip top and bottom of thermostat". Haven't tried, but can see the reasoning behind the theory. Also have replaced cam seals, (twice, second under warranty) oil pump seal, valve cover gaskets (all at 58K). Power steering pump leaked at 50K. Been adding Lucas, seems to work. Sell it (full disclosure) or fix it for $1,200? People in my area are selling similiar mileage rigs for $10k with average askings on higher mileage rigs, i.e. >110k, between $7k-8.5k.
