PCV valve on 93 honda Civic DX

I have no clue where it is when i pop my hood, i checked everywhere with a flashlight. A buddy of mine told me it might only be accessible under the car next the the fuel filter, but he said hes not sure. I want to change this asap but im not much of a mechanic so i need some help from you guys. if you have pictures that would be great

on the back of the engine block (toward the firewall) there should be a black box on the top youll find the PCV valve

I checked with a flashlight very well and found no black box and no possible place to attach this. Could u be a little more specific plz.... is it changeable through the hood without removing other parts ?

should be on the intake manifold between two of the runners, don't remember which two though.
