    It attaches to a manifold vacuum source

    I am having difficulty finding the location to the valve. I thought that it should be on the driver side valve cover, but that outlet is permanently attached.

    My fear is that the previous owner jb welded a plastic coupling in place of the pcv.

    I am getting codes for lean banks and having weak acceleration up hills occasionally.

    Does anyone have a picture of the place where the valve goes and a description of how to replace the valve?

    One side (valve cover) has a PCV valve and goes to a manifold vacuum source and is a smaller hose. The oposite side valve cover is the vent side and it should have a larger hose that hooks up between the mass air meter and throttle body.
    If you are getting a lean bank code the vent side is probably disconnected somehow and allowing unmetered air to enter the system between the mass air meter and the throttle body.
    Take a picture of the suspicious location for us if you can.

    I solved it. I was looking at the vent tube thinking that it was where the pcv was supposed to go because the other hole in the valve cover (passenger side) had a plug in it. After researching, I found out that the pcv was supposed to be on the passenger side. So I searched farther back on the cover for the pcv, and I found that it was not hooked up. It was hiding in some hoses. The previous owner must have lost it and replaced it with a plug.

    Now, I need to erase the codes and see if that was it. There are four codes, but I think this could have been responsible for all of them.

    Thanks for the response.
