So okay wrx parts sounds good. The engine has had new plugs at around 199 thousand miles it just had a new air filter the previous owner said new fuel injectors around 180 thousand it's got over 202 thousand on it right now. The engine runs well goes through the rev range well just sounds like there's a compressor going off at idle maybe a pump but not sure and it doesn't smell well when it's driving not oily but like its not burning the fuel well and it leaks oil like every Subaru as well that's why I'm thinking of a rebuild also I would like to put a turbo on it for a bit more HP
