Hello, I recently acquired an 08 Legacy 2.5L non turbo that has a leaky head gasket(s). Not sure if it's one or both but I am trying to identify a reputable repair center in the Washington D.C. area. I am also new to this area. Hopefully there is a place that knows how to do this without pulling the engine which seems to be the driving force behind the dealer quotes of $1200+ per gasket replacement. Any info would be greatly appreciated.
