By early subaru's, they mean Loyale's and XT's, the EA82 engine. They were notorious for blowing head gaskets. These cars have more or less the same engine design as present day subaru. things have been about the same since 1989, when the "ej" series engine came out. Regular maintenance of these cars is basic, yet it has to be done. Oh, if it dosen't have synthetic oil in it put that in straight away. Its a ej22 turbo closeddeck block, the strongest block subaru ever built.
