This is my first Subaru in about 6 years, my last one scared me off. Anyway I've only just brought this Subaru Legacy 1998 GT BH5 wagon and have had it two days. The first day as I were going up a hill it begun blowing the blues, engine check light came on. I Ran diagnostics when I got home and found it was the oxygen sensor, ran it past a mate, he second the notion. So i replaced that the next morning, ran some upper head cleaner through it, Cleared the code and went for a good drive (like a nana) out of town. It seem to be more efficient on gas, everything seemed fine, but when you drive like a nana of course it does. Note I've always heard whining from what seemed the turbo/s, which I never had with my previous GTB, not like this. This sounds more clunky and erratic.
Returning to town I were going up a large hill and went to 'put the boot' up her, once in the 4k rev range all I could see in the rear vision mirror was white smoke and smell burning oil, there was no boost following the primary, in fact a drop in power. I thought the "secondary is gone". It would also explain the 02 sensor going I guess from all the residue passing by it.
Can people please confirm this is most likely what's happened. Looking at the secondary it is filthy. Unlike the primary, which I do feel kick in about 3k revs. Just confirm Primary passenger side, Secondary drivers side?
