okay, i've searched for a few hours now and i cannot find the question to my answer.

I have a B18A1 block with a B18B1 head.

I have the black breather box on the back of my block and there are two ports on top.

one port has a hose running from the box to the back of the block

my question is, where do i run a hose to from the 2nd port?


and what is the CORRECT way to hook up the PCV system / black breather box?

 

The other hose connects to the PCV valve. There is a spot in the intake manifold above the black box where a hose with an opening for the PCV valve goes. The hose from the black box has a PCV valve like plastic valve at the black box and a square end that fits into the intake manifold.


#3 is the valve that fits into the black box, #4 is the hose with the square end, #6 is the PCV valve.

Your confused because you now have 2 locations for the PCV valve. Your B18A block has a spot for the PCV in the black box on the back of the block and your B18B head has a spot for the PCV valve in the valve cover. I would just pick one location and block off the other. Hope this helps.
