i went to change my induction kit today andnoticed oil around the maf sensor housing (inside). ive removed this and all inside this is oil, its black oil coating the inside of this pipe as far as i can see. I have NOT got any oil in the water system from what i can see. car has been a bit sluggish recently and doesnt always boost fully and then will 'go' as though its got a blog that clears. it looks as though thisoil could bethe cause but what is this?????:(
