i was just reading a thread on location of the pcv because under boost it suck oil into the intake .can anyone add too this if true.im asking bcause i was going to change my valve seals this weekend bcause i thiught they might be bad .i do have my pcv into its factory location and when im into boost hard i get black smoke.this is a fairly new motor so i dont think its any more serious than this issue but im real curios about this whole pcv location cause that would make some sense and i might not be changing valve seals,ya know .if this is true where do you put the pcv?or do i for now unhook it from the intake and plug off.?
