    pcv location?with boost

    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.?

    black smoke is fuel or detonation. Blue smoke is oil. I put a K&N filter on my drivers side valve covers. I don't use half as much oil between changes now.

    2b honest i dont know if it blu or black ,but im not getting any kr or rattle and my a/f is fine .allen said that looks good .im thinking its dark blu ,,im not usually looking in the rear view but i saw the puff a few times tho and i use alittle oil.so i can just go without a pcv and use a filter like u use ,anyway just to find out if its the source?

    Yeah, that is from the PCV sucking in oil vapors from the valve covers. I would HIGHLY recommend you get a Catch Can for the PCV. That would solve your smoking issues...
