2002 subaru outback limited 2.5 blew all the coolant out the fill of the degas tank and coolant in the oil. Our temporary fix was to refill and drive home about 5 miles with out any more problems. Our permanant fix was a 2013 Kia soul without the hampsters. Now i have a car we have had since new which owes us nothing and a 15 year old daughter that will be driving in less than a year. What do you think the internal damage is from the coolant? My plan would be a compression test, remove engine and replace head gaskets and timing kit or install reman engine or install a salvage engine with new head gaskets and timing kit.
