Subaru fix for head gaskets was head gasket conditioner (aka Subaru branded stop leak).

My parents have a 2000 Forester since new with 199k with no engine work . Not the common thing . Personally I I wish it blew the engine grenaded years ago because the vehicle is so awful when new and worst with age. They finally got a 2015 Outback and such as pleasant vehicle.

Apparently not. A friend of mine had a 2000 Forester from new until it succumbed to head gasket failure at about 100k miles in 2012. He solved that problem by buying a new Forester again. It has been ok so far, except the wheel bearings.
