oldcar... Yes I agree  greenbirds has helped me thu many problems.
I found a PVC replacement for a 1961-2 Ford Mercury 292 on E-Bay in the original package. It has a 1/4' threaded end and is to be for the rear of the carb. It was made by Union Electrical Parts in North Bergen N.J. and has a price of $1.57 still on it. #PV580. It fits other Fords, none newer than 1964 but It could have been made then. I have the correct valley cover for it and still need to put it on.

I’m pretty sure Steve did a PVC restrictor too. What I don’t remember is how he determined the size, or what he drilled the plug to.

FWIW, if you can’t find a “closed” cap like DLR mentioned, or if you’re using aa aftermarket valley cover, you can get oil fill tubes with a closed cap. My bird uses the sealed tube, with a threaded bung from a 69 Camaro. Painted or chromed.

I always run closed systems both for the filtered air and the reduction of vapor smell.

I don't recall him doing a pcv restrictor.

For his cooling system a part of the modifications was a restrictor in the bypass hose.

I was looking for Greenbird56 old Post regarding Restrictors etc. He's a pretty smart Guy with this Type of Stuff.

  

oldcarmark Are you wanting to see what I did? I never put the photos anywhere but will do it here in a reply if someone wants to see them..

Anyone know where this Post is and can You provide a Link? I couldn't find it using Search.

  

I have a suggestion for the upper side of the addition of a PCV system for any engine but especially our Y's. Your oil fill tube at the front of the engine breather should not be open to atmosphere when adding the system. The manufactures do not do this; the "sucked" air for this system should be "filtered" air from inside the breather of the air cleaner you choose. The normal push on breather does have some filtering material but I do not think it's sufficient and allows the "smell" after shutting down. I purchased a push on cap with a 1/2" tube and ran it to the area in the inside of my air cleaner thru a homemade double 90* fittings, thus the air being drawn in by the PCV will be be better filtered.
This will also work for engine with no PCV system if you don't want blow-by under the hood but it is not for that but will work. I can post photos if anyone wants to see what I did.

Ted: Thanks. I should have mentioned that I did remove the attachment pce from the oil shield & soldered a pce of metal into the hole. The shield appears to be flat & the valve I'm using is only 3/4" deep to the flange & seats fine. However, I was concerned about oil drainage, so I drilled 3 small about 1/16" diameter holes around that area. So, that was probably a mistake to do that?.  If it matters the carb is similar to the Autolites introduced in 1957 but is actually original to a SBF, 289 Mustang, of 1965. (paper with it indicated it was apparently redone by Pony Carbs, before I bought it & appeared unused )

When the PCV valve was put in the rear hole in the valley cover, was the hollow threaded stud for the original road draft tube retained or cut down?  I typically remove that hollow stud when I install a grommet in the valley cover hole.  This allows the PCV valve to fully seat within the grommet and still clear the 'shelf' beneath the valve.  If the stud was removed, was what remains of the original threaded hole plugged?  I just put a 1/4-20 bolt and self locking nut in that hole in the lower shelf which prevents a direct path for the oil to get to the PCV valve.  It's also important to insure that the shelf has not been pulled higher or upwards towards the PCV valve as that could have happened when the original road draft tube was over-tightened thus pulling the shelf up higher.
  
I use the Microgard 2322 PCV valves for the Y engines.  These are used with the more modern carburetors that are also designed to use PCV valves.  Early carbs tend to be on the lean side when retrofitting PCV valves and will require some tailoring of the idle circuits to richen up the fuel mixture accordingly.
