First pic is your pcv valve, needs to have a vacuum line ran from it to your intake manifold. Second pic you are correct, needs to be ran to intake, after maf that way if you have blow by gasses the engine is not wasting metered air. The bov is def not the cleanest setup ive seen but if it passes a boost leak test without blowing off of the pipe than I guess it could be ok. If the maf is before the turbo than the bov release end needs to be routed to the intake after the maf. Hks sells the recirc fitting for that bov for like $20 shipped.

One thing I noticed is because you have an equal length manifold the stock catch can was removed. If you run the valve cover to the intake again make sure to run a catch can in between.

exactly what i needed to know thank you, i found the fitting to recirculate the BOV.

I have a "greddy style" intake manifold and its missing the extra vacuum line fittings needed to attach the PVC too, been searching everywhere for info on these vacuum fittings with no luck.

and whats the best way to go about attaching the line from the BOV? should i get a new hot pipe that has holes already in it fpr vacuum lines? and whats the best way to attach that BOV so it doesent look janky anymore?

On the greddy style mani, (i have one also) there are 2 fittings that are in the very end of the mani, one line goes to the brake booster check valve the other should go to the pcv. Your local "hoses and fittings" place should have the right elbiw for you. If not you can t off of the booster for the pcv. Im not sure what your asking about the bov. It recirculates to the intake not the hot pipe. But yeah, if you can find an intake that has two ports, one for the bov and one for the valve cover vent than that would be perfect. If not than steel or aluminum pipe and have it tig welded. As for the bov with the rubber hose thing I would order the bov base flange and have it tig welded or there are hot pipes with the ssqv flange you can just buy.
