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?

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.

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.

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.

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.

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.
