    I just capped off the port on the throttle body on mine. I also removed the plastic pipe coming from the drivers valve cover to the air cleaner, I just put a chrome valve cover breather in it's place.

    Just cap off any vacuum lines, I personally replaced all my lines when I done this and just left them out. For the hose I upgraded to 1/2 heater hose and used a ford 90 that fit in my fiero valve covers then attached it to the spot on the air cleaner. (that first pic was old before I had the fiero valve covers)



    Thats another old one, before I done hood struts and headers, lmao. I really need to get this thing back together and get new pictures.

    Whats the best valve cover gaskets to get for these things, Ive noticed a tad bit of oil on the back side of the drivers side of one for the covers. Im gonna go ahead and change them just to prevent any bigger leak from happening

    The rubber ones used with the fiero valve covers is the best but I'm a bit partial maybe.

    Fel-pro is my gaskets of choice. When you swap them out make sure you clean the surface really well and put a dab of silicone where the intake mates to the head under the valve cover.
