    In the process of putting on the oem intake manifold after taking off the supercharger, i am left with one vacuum port that i cannot find a hose that goes to it. The port in question..4F3DCCA5-45BA-4011-A56B-FB8552E345EA.jpg76D7C197-F2E2-4C09-ACDC-FC0D938CC7D5.jpg 79767CCE-90F2-4376-9880-75C2DABEACE2.jpg 35B0854F-FBEA-4230-9689-8A8D9290AF1A.jpg It seems to run back to the pcv valve. Can anyone tell me where this port on the back of the manifold is supposed to go to? It is the only one not on the diagram under the hood. Thanks for any help.

    I think i figured it out. Im pretty sure it goes like this with the port previously in question going to the fuel pressure regulator. If anybody sees this and its wrong plz let me know. Thanks.BFDC0DD8-8B11-487A-BC73-8FC830258CC9.jpg

    Hi: Here are photos I took before I changed my valve cover gaskets. I think you have your PCV valve going to the wrong port according to your sketch on your picture*. Inked20200627_145043_LI.jpg Inked20200627_145123_LI.jpg

    Agree with above post. You have the PCV valve hose routed wrong, and therefore the other line as well. See red line below for PCV.

    This pic is from my 95 3.4L. It has a VSV in the other line. I don't know if yours' will have that or not, but routing should be same from plenum to airbox.

    Yep I ended up routing them correctly. Thank you to all who helped.

    Your correct. But if you look close his nipples and arranged differently.
    And your second picture you have the fuel pressure regulator circled. the pcv comes up and over the intake plenum, past the throttle body and plugs into your intake rubber boot between the MAF and the throttle body. Right area is circled, but its behind that. You can see the hose tho
