Just searched ebay again and found two different style caps with the same Stant SO70 number. Here's the one I got. Seller still has 8 of these NOS caps.

Stant SO-70 is the painted version and exactly what I had in mind. Got the number from Jim's link then found a guy who has some NOS for sale on eBay. $9.99 including shipping. Now to locate a suitable pcv valve. Thanks guys.

Stant 10070. I believe it is chrome. A Scotch Brite pad and some semi gloss should make it look stock if that's what u are looking for. Good luck. Show us photos when it's done.

A filler cap for a late 70s/early 80s Chrysler 318 may fit and it has the nipple for the connection to the air cleaner. I know they fit the filler tube for late late model flatheads and it looks like the y-block tube is the same diameter.

Bill, I wish I could be more helpful but the system I have was salvaged off another engine, I believe it was a 1962, I got the valley cover with the PCV and hoses and the filler cap from it. Macs has a similar cap  listed for trucks, there maybe other places to get them.

Great info! Without changing my oil fill tube, is there a good aftermarket cap with the hose fitting available, or a specific old one that will seal and do the job? Also, which inline pcv valve are you using Jim?

I'm using the same set up as yours. I have the PCV valve inline between the valley cover and the carb. To use the manifold fitting would have required a large loop of hose to avoid sharp bends and kinks, going to the carb allowed a shorter hose with a smaller loop. I also use a filler cap with a hose going to the air cleaner.

Bill C that's correct. Most forget that the PVC valve is a flow device so the vapor it is sucking out of the engine is actually thru the engine and it should be filtered air. If you remember many GM cars had that filter inside the air cleaner but outside of the carb air filter and is an easy one to add. Many of the early PVC valves were threaded and I have one of those 69 camaro fill tubes withe sealed cap where you would place the valve. If that style is used however there should be a breather cap on one of the valve covers with a hose up to a filter also that's how they (GM) did it. Good luck and I like what you've done so far..

Short answer, yes. I'm using a PCV valve very much like your fitting in the valley pan. Goes into a grommet, and a hose to the carb fitting. I've used the manifold fitting like you show, also.

One of my cars has the closed cap, running to the a/c. The bird has a finned valley cover and I used the fill tube off a 69 Camaro. Sealed cap (looks like a radiator cap) with a bung for a fitting to the a/c. The OEM application was a PVC that screwed in there, I used a barb.

One caveat. The original valley pan didn't have a baffle, and I used a Moroso grommet with a "duck bill" design, to limit oil flow. When I built the new motor with the high volume/pressure oil pump, it didn't control the spray coming off the dizzy drive. That was a blower motor. Blew the head gasket on #7 twice before we realized the oil contamination was the likely cause. Welded a proper baffle under the valley cover, no more problems.
