I am looking into buying an 05 Legacy Outback Limited. The vehicle has 124K and has the 2.5 Boxer engine with the Turbo. The turbo and the Cat have been replaced, as well as a tune up. Unfortunately, the turbo is leaking oil between the engine and the turbo. There is a loss in boost and also a loss in power. The engine hesitates and idles rough. Anyone else have this problem or know what the issue is?
