I'm using a small shop called Auto Advantage in Concord, NH. A BMW and Euro car specialist who happens to be an 8 year veteran of a Subaru service department in Virginia. My 97 Legacy Outback (144K Miles) is new to me, and with a 2.5 L engine I thought it had head gasket problems simply because there was grease inside the coolant overflow reservoir. He has tested it for combustion gases and found no problems, but I need to throw money into the timing belt change and rollers for same, plus oil pump seals. I will report to the USMB my experience there.
