The dealership says that I may have a couple of stuck valves in cylinders 2 and 4. I need some advice pertaining to this. The mechanic at the dealership said that I might be able to use some decarbonization methods in the fuel and air intake systems to get them unstuck. Does anyone have anything they recommend?
If not, they said that I need new heads. They quoted me $3500 to do this, and I don't want to spend that :-/ Anyone know if this is a difficult replacement, and how much I'd be investing into it? I'm pretty mechanically inclined, just don't know much about the boxer engine yet.
Oh, and its a '02 WRX with 75k on it.
