Cool 1960's aftermarket valve covers. Any ideas to make a PCV system work?

While looking for other parts this evening I came across some old aftermarket valve covers. I got these years ago and am planning to use one set on a 1964 Cutlass and the other set on a 1965 442. But looking at them I'm not sure I can make a pcv valve grommet work on either of them. Anybody use these covers and figure out a way? I believe the factory covers from my 1965 have a rubber plug on the one side, and a breather on the other. So should I run these without a pcv setup? I think these would really set off the engine compartment so I'd really like to use them. Anybody have ideas they could share? John

Almost looks like those were setup to handle a draft tube vent. It could also be Offenhauser set them up to use a Ford type PCV valve in which case you need to measure the recess diameter and depth to see if there is a Ford grommet for seating a PCV valve into it that would work.

Added: I don't think you really want crankcase fumes blowing into the car which they will with other than a PCV valve. Don't take but about six months even on a fresh rebuild for the crankcase fumes to smell like heck.

I've only seen these used with vents; maybe you could drill the intake manifold for a PCV valve (a la a '69 HO) or even rig something inconpiscuous up off the oil filler tube.

66 327 L79s use a PVC system that would be easy to duplicate on an Olds, the PVC valve actually screws into the oil fill tube and is routed to the big port at the base of the carb..they have a road draft tube too, but the breather you show would take care of that, a little work and you could kinda hide it...

it would keep you from drilling and screwing up you valve covers...just an opinion...

The cover with the tube sticking up, I'd just use a piece of rubber hose and a spring clamp. Then I'd go to the store and find a pcv with a big inlet and clamp it on.

The one with the recess, you could probably just find a grommet and a breather for.

These are real handy.

And these are great to keep the pcv from sucking the oil splash.

My Uncle Carl has been looking for those for a while now. Thanks for finding them. If you want to mail them to me I will make sure they get back to him.

I have the Offy covers also and I found this set up from Earls. You can buy the two breather set which is a PCV on one breather and a regular breather on the other. I thought it was a great idea. I haven't done it yet but my Offy Valve Covers have tubes extending from them and I was figuring on just attaching to them.

Thanks guys for your suggestions. Yes I'd like to run these without drilling any holes in them. Richard, tell your Unc that I'll take real good care of his valve covers

I like idea of going to oil fill with pcv valve and vacuum hose. Breathers in the valve covers

I don't want to insult any one but the oil fill tube dose come out,don't drill it with it on the engine.
