PCV Valves

At the moment i am in the stage of doing all the plumbing to suit the 383 SBC going into my 32... I would like to kepp the valve covers clear with no breathers or oil filler so i have planned to drill and tap a hole in the rear valley of my Victor Jnr manifold to use as a PCV input and then plumb directly into the back of the carb...

Can anyone see any problems with this setup? I have based this theory on a few early small blovcks i have seen (and no not the ones with the oil filler at the front!) and i cant think of any reason why it will not work..
One problem i know of but will get over is the fact it is going to be difficult to put oil in, will probabbly just pull a valve cover to do this...

Without proper baffling, the PCV will suck oil.....Pontiac used that idea but had the Gallery cover plate baffled and it worked well.

i use moon valve covers on all my builds. i have put the pcv valve in the back of the intake on all of them with no problems.

I've done a few this way as well, in addition I fab up and epoxy on a small sheet metal baffle along with a lifter valley baffle for insurance...

i put one in without the shield and ran a clear hose for a while. never really sucked oil, only vapor . i also used the baffle gromet .

Shine's setup looks good.

I can tell you from experience that you can suck oil if your valley hole is too close to the side. I used an existing hole in a 3x2 manifold(Offy) and it sucked oil. Just too close to edge of the valley not to have a baffle.

i set this motor up for a friend. i hard lined around to the back of the center carb.

Another option would be to put the holes in the rear ends of the covers like I did on these. I didn't want anything on the top of these one-off covers so I put the PCV on the drivers side and a hose on the other connected to a puke tank with a breather.......

Will the PCV placement be OK if it is placed on the small flat section near the distributor? (im running a victor jnr) From reading the above posts it is clear i need some sort of baffle, would anyone have a picture like something i need? what is the ideal method to fix the baffle?

Thanks for your help so far guys!

you can get a grommet with the baffle on it. it is closed on bottom with an x cut into it. i've done it without the baffle . not much oil slinging in the center.

Thaks for the help so far guys, much appreciated... I am now clear on the PCV valve but my next question is with regards to the valve cover breathers... put simply i do not want to see them, is there any way around this that anyone knows of?

Heres's a pic of what I mentioned above...hose in back of cover to a remote puke tank with a breather...
I do have to pull a cover to fill with oil however.
