I have a 2010 Legacy and a 2004 forester and they both need new head gaskets. The legacy overheating and the forester leaks oil. I could use the name of a good mechanic in NE Pa. I also would like to know how hard it is to change the head gaskets myself, it probably won't happen because of time but I have changed head gaskets, Transmissions and engines in the past. I would be thankful for any information. Also , Hi to everyone in the group I just joined this morning. Lee
