PCV setup

[Gunner]

AFAIK. It has to be a proper PCV system for smog control (they don't care about crankcase venting; they just don't want the fumes in the atmosphere.) You could take the whole thing off, or go to an open system, after the BAR check.

There's no downside to the closed system, vented into the air cleaner, except non-originality and potentially ugly tubing runs.

Right, the extra tubing usually doesn't look good. But if you can pull it off after the test, then it really isn't much of an issue at all. Just plumb it up to pass and forget the looks.

If you go to the BAR on Florin in Sacto, George is going to want to see incoming/outgoing in a closed loop; nothing escaping into the atmosphere. As soon as he sees you don't have it, he will show you a diagram and ask you to go home, follow it. If you show up with out the proper system in place, he'll turn you away and send you home on the spot, no pass go! It happened to Dan L. last week. He wants to see no breathers, tubes, vents or devices of any kind directly escaping into the atmosphere. Just trying to save you a 1/2 a day, trip over and back twice, if you can get it right the first trip there. I had a kit I gave to Dan, but he had to use part of it and still has part on his car. If you go to Florin, he will check, specifically. Just a heads up.

On the two times I passed the visual, I ran one from a breather on the valve cover to the air cleaner with a 90-degree fitting and the other from the back of the manifold to the back of the carb. The last time was for SB100 and I just had one line from the breather to the base of the air cleaner and it was approved.

Here is an original PCV diagram for 1965 390FE to reference/simulate from.

That's my understanding of how it's supposed to be, however many times another referee will let things slide. I'll do it right. If I do a clean job on the valve installation and plumbing, it will stay; I *might* pull off the vented breather for one that's open after the exam, just to reduce the tubing count.

After all (sigh) I have three months to do it. I could hand craft it out of popsicle sticks in that time. Or hand-carve it out of billet. Where'd I put my whittlin' knife...
