What PCV valve should I use if doing the install that oldcarmark mentioned on a post.

I used the Moroso Baffled Grommet on mine. 4 Years works fine. No excessive Oil usage. You can use that with the existing Valley Cover. Just use a Hole Saw to cut proper size Hole. I used the correct Grommet that fits PCV and Super Glued it inside the Moroso Grommet.[/quote]

When converting the rear hole at the back of the 1955-1957 T-Bird valley covers or the 1958-1964 car/truck valley covers for a PCV valve, I will remove that threaded extension that’s in the center of the hole.  The remaining hole in the baffle is directly under where the PCV valve and for that I install a ¼-20 bolt and nut in that hole so that there is not a direct path for the oil to get to the PCV valve.  For the PCV valve I use a Dorman #42323 grommet and a Microgard #2322 PCV valve.

Here’s the one I use on my 312 from NAPA. The valley pan is stock containing the screw post for the RDT. I just inserted it deep enough to hold it, it’s not contacting the screw post the allowing engine vacuum to open and close it normally. I have at least 1000 miles on it and everything seems to be working fine wo excessive oil consumption.
