I need to overhaul the exhaust valves in my Legacy. For some strange reason\nthis has happen at just 125 000 km.\n\n\n\nThis Is my 7. Subaru and the other have run smoothly in many more thousands\nof kilometres without any serious problems. I am quite surprised and\ndisappointed to expire this.\n\n\n\nDo I need to take out the engine to dismantle the cylinder heads? Have some\nof you a good description of this operation so I can do as much as possible\nof the work my self. In Norway this is very expensive to do at a Subaru\ndealer.
