1974 Mustang II PCV Valve help. Apparently, I need one for a V6 engine to help pass emissions this year. This is not the type that goes through the rocker arm cover, but the one that screws into the manifold. So far, I have been unsuccessful in locating a replacement. Any ideas or suggestions on where to look or something I can use as an alternative?

This sounds as though you have run into a dealer only item. You may have some luck in a U-Pull-It yard. Look for Ranger pick ups and Pintos also. ---Chuck

Are you looking for a PVS (Ported Vacuum Switch)? Motorcraft still makes them. I found one at partstrain.com
