Manifold PCV Do's and Don'ts or Don't do?

[Thumperbird]

Hello, have always fought some oil in the pcv/carb on my stroker, had to remove the baffle in the fabricated valve cover due to rocker clearance issues.
Was wondering about using the oval shaped plate access at the back of the Edelbrock 2x4 performer manifold, pro's and cons of this idea, do's and don'ts?
Seems easy enough to pop a whole in the plate and run a pcv straight up into back carb., would I need to baffle the plate on the back side? 
Not sure how much oil is flying around the rear of the galley?

Thanks.

I believe that there was provision for a wire wad baffle under the plate when doing what you are proposing.

There's a tremendous amount of oil in the lifter valley flying around and on some blocks, there are some big holes in the back where you can actually look down and see the crank counterweight.  Lots of oil flying through the air.

I'd be sourcing a different set of covers or possibly cover spacers to get the baffle back on the PCV outlet.  Or plumbing in an air/oil separator.

I built this setup for my Mustang.  PCV line from valve cover valve goes into the 2 stage separator tank which has a drain tap at bottom. Then the intake vac. flow travels from tank into a clear type fuel filter to catch anything that comes thru and also a good visual aid as to how it is working. I get about a teaspoon or so of oil after a month or so of cruising use when I drain the tank.
I mounted the PCV valve at front of valve cover.

That is a good idea.
i have a new oil seperator for my 63 but never thought about running a filter in the line.

Thanks all, was hoping this would be a quick fix, not that the proposed ideas are too big of a deal.
No clearance for taller covers on drivers side, will look at separation methods, was thinking a pcv up an inch or two off of the back flange would by me some distance from the oil and if large enough diameter reduce air velocity so the oil stays low, maybe add some mesh, so might try and fabricate a little tube extension so to speak with mesh and pcv on top.

Thanks again.

I've added some SS mesh under the interior baffle with good results. Trade name is Chore Boy, a stainless steel scrubby, available at grocery stores . If you don't have a sheet metal baffle inside the cover (I stuck my mesh between the top side of the baffle and the inside of the cover) maybe you can stuff some of it into your extension.

No lifter galley baffle on your combo?, (assuming roller lifters).

I have an issue as well with my 67 Shelby with the PCV pulling oil into the intake. I packed stainless pot scrubber material from Brillo on top of the baffle in the valve cover. It made a huge difference.

[Thumperbird]

Correct, no lifter galley baffle due to rollers and no valve cover baffle due to clearance issues inside and out, some space to play at the back of the intake though as carbs are elevated a bit.
So yeah, hoping a decent diameter chamber filled with something will do the trick, figure bigger diameter should mean less velocity coming in before it gets to pcv therefore pulling less oil for a couple of reasons.

Options available.
Not sure which basket type is better, the mostly closed bucket or the more open mesh holder.

Might try reducing flow through the PCV valve...either with an adjustable PCV valve (expensive) or insert a smaller diameter hose inside the PCV hose. 

Oil turns into a misty fog over the rocker arms (and I'm guessing it will over the lifter galley) around 2500 rpms.  It floats around and right past baffles. 

[Keith Stevens]

I can't use many of the options available because if having to keep the car stock in appearance. The reduction from the 1/2 hose internally is likely a great idea too.

I ran a pvc in the rear on my Manifold i made a mistake and did not install the basket I used 2.6 quarts of my 8 quart sump in less then 100miles no damage done and i had my roller lifters oiling restricted and push rod oiling only rocker oiling was blocked off at the block due to TD race rocker mounting plate blocking the std oil feed hole at the head that should tell you there is huge amount of oil that finds its way to the top of the valley. I removed mine and blocked it off i don't run a pvc now my valve covers have breathers in each one + the oil fill tube. Zero problems now car is running great first oil change was last week oil filter looks good and clean apart from the normal fresh engine ware. I would avoid using the rear of the manifold and less you run a vent tube and the basket is 100% required.
