Yes, anywhere that leads to the crankcase.
Not sure how much oil may get sucked up from there though.

 

If the 283 has the oil separator under the intake for the road draft tube hole... You can put a PVC there and fresh air is pulled in the front fill tube cap / breather .

The oil separator under the intake in the lifter valley is a round canister looking device. One bolt holds it in place.

Chevy also did the same thing in reverse. The road draft tube hole was hooked to the air cleaner via a fitting in the hole and rubber hose. The PVC was on the front fill tube thru a welded on bung fitting. The front fill tube used a solid cap , not a breather style cap

 

Seeing that the oil fill breather is designed to keep oil from escaping & not as a crankcase air intake ( no filter) , the way chevy did it was to protect internal engine parts from ingesting dirt , the reason the hose came from a filter in the air filter housing , is by far the better way to go . Im curious as to what port goes into the valley ??

 

my thought was the vented oil fill tube in the intake for air inlet. where can i put a pcv valve for an exit to carb vac

 

Do you have a plan as to how to put a filter on the breather tube ? You can drill the manifold && weld a threaded bung in it for either a hose fitting or a thread in PCV valve , there are also on line pvv valves .

 

the front of the manifold pictured has an oil fill tube with a vented oil fill cap. the 283 had a raoad draft tube at the rear of the engine air came in the oil fill tube and exited the "draft tube. newer blocks do not have the provision for the draft tube. i am kooking for ideas how to not drill the script valve covers to get a pcv valve at the rear of the valley.
i do have a pair of old edelbrock valve covers that i could use but i like the scrip covers better. maybe i am not explaining well enough

 

You will need to drill the valve covers

 

There are multiple ways of Installing a PCV system without drilling the covers. You will however need to access the valley through the intake .

 

thank you.... they probably will hang on the wall..

 

Drill and tap a hole into the intake manifold thru to the valley, in the area behind the runners near the distributor.
then fit the manifold with a screw-in PCV or a hose barb and inline PCV valve.

 

To avoid putting holes in the script valve covers you will need an older style intake manifold that supports having an oil filler tube at the front and a road tube at the rear. The last production engines built with these features was in 1968.

Occasionally you find aftermarket intakes with these features on EBay, Craig’s List, Racing Junk or local swap meets. Some current production intakes retain these features in the casting shape but are not machined.

Depending on the valve covers you have you might find a location where you can bore holes for breather caps somewhere that the script isn’t damaged and the rocker arms are cleared by any internal protrusion by caps or plumbing attachments.

You're into one of the reasons I don’t build show cars as the emphasis on clever or pretty eats a lot of time I don’t consider productive. This is an easier direction to follow for Harleys as there is a large number of parts producers making ready to use pieces and yes I have a pretty glittery Softail but in a reversal of my car and truck activity the hog is more glitter than go though the go side has some improvements it’s no where near pushing the envelope.

the intake i have in the picture IS a vintage piece with the oil fill tube. i may hang script covers on the wall. and use the edelbrock covers pictured here. probably painted black timing cover black intake orange.

 

I would pop a small 3/8 diameter hole and use a bit of copper tube in the script valve covers to the back side. Braze in place. Then plumb as needed

 

Yeah I know the block was different, just got lazy on writing more detail as it seems every time I sit down the old lady is up by butt about something needing my immediate attention. I fairly safe right now sitting in the bathroom with the vent fan running and spraying Poo Pourri so that will buy me a few minutes.

To the OP either use the Edelbrocks in the picture or take the script covers to a pro that can weld on aluminum which I presume they are and pay for the modifications. The nice thing about putting the oil fill and venting on the valve covers is it opens up more modern intakes which do a much better job of feeding the ports than these older design intakes, you’d be amazed at the runner by runner differences in flow of intake manifolds. When you grasp what the intake is doing or not doing you quickly realize the folly of porting heads as if the intake can’t supply 250 CFM and most can’t, then having that or more at the port is just a waste of time.
