Excellent !!
OK. You asked for it, you got it.
This is how I accomplished this in my Pantera. The same tank is being used in my Shelby's. It is billet aluminum. It has a sight tube on the side that will show what is in the tank and a petcock underneath at the bottom to drain it.
It is plumbed between the pcv valve and the vacuum source. In the case of the Pantera it is a vacuum reservoir made out of a Mr. Gasket fuel log. It was used because it fits so conveniently just behind the stainless header heat shield. It isn't showing up well because of the lighting but it's there, plumbed in series to the individual stainless tubing coming from each of the intake runners.
It's a Weber manifold so it's an individual runner manifold and just to get engine vacuum you need to plumb them together.
I think the pictures pretty much explain what is going on with it. The oil that gets sucked in just drops to the bottom of the tank and a minimal amount gets sucked into the intake manifold. It's not 100% efficient, but is highly efficient, or maybe...good enough for my purposes.
The Shelbys are using the same tank. In my '68 GT350, the battery is in the trunk. That provides enough room against the front of the right shock tower to mount the tank. In that application, the tank is plumbed with -6 Russell braided stainless hose from the pcv to the back of the intake manifold.
The intake there is a C60A, 2x4 Holley Trans-Am intake. It's got only one vacuum port and that's at the back up against the fire wall. So what you will see is a gaggle of braided stainless hose for the pcv, the fuel line and the heater hoses all occupying the same space between the back of the valve cover and the intake manifold.
I tell you this so that you can choose to avert your eyes from a completely non-stock assembly and consider praying for me at the alter of Concourse only worship, asking for my forgiveness? I'd appreciate that.
I always hesitate to post pics like that not only to avoid the accusations of blasphemy but in addition to criticisms of why I used blue hose ends vs. pink or purple and why I feel the necessity to be so overly machismo. I tend to ignore those comments these days and just rack that up to those who have choosen to check "other" on their California drivers licenses rather than male or female, or should that be mail or femail? Hum? Another alternative I suppose.
Well anyway, here's the Pantera. You'll get the idea. The parts are all here for the '67 500 but I have no idea exactly the details of where the plumbing will be located or even the tank. Evey place I try, I come back the next day and nix it. There is FAR less room in that engine compartment then the '68 350's.
I keep trying to go Akashic but so far the Akashic Records have not offered me any kind of solution. That's disturbing. One would have thought that in the total time of the Universe that stems from before time existed, some creature somewhere would have come up with a solution and shared it? Maybe that was the part about "get a horse", I don't know?
What's with the picture feature here? Three of the four got rotated 90 to the left? Do we have Russian hackers here? I thought that they only twisted things to the right?
