"smoked like a b*tch" sounds like a turbo problem (which you had), and if it's smoking the same..?..
P.J.s car didn't smoke, as far as I know.
IDK, valve stem seals don't usually cause a car to "smoke like a b*tch", but then, I guess that's subjective...perhaps we have different ideas as to what "smoked like a b*tch" is.
