My daughter's 99 Forester developed the dreaded head gasket issue last fall. The repair shop we use for things I can't fix told her the head gasket blew and needed replaced. They quoted her $1300. She is a college student and needs her car daily. As a temporary fix, the shop suggested the Blue Devil gasket maker. It has lasted 6 months, however, her engine has started to use coolant again and I can see the bubbles in the overflow bottle.
Is it safe to use the Blue Devil one more time until we can afford to have the head gaskets replaced? I've heard both good and bad about the product, some stories saying it completely sealed the radiator passages and engines have overheated due to lack of coolant circulation.
Thanks ahead of time for everyone's input and thoughts.
