@stevebuchanan posted:Doug, are you running PCV on Webers or 8 stack EFI?
Yes, a M.E.Wagner and I am using an oil sererator/catch can as well.
I only have 12" at idle so I found that I had to regulate the "vacuum leak" by installing a plug in the passenger side breather and limiting the size of the hole that the engine sucks air in through. Otherwise I lost 3-4 inches through the stock breather hole in the oil filler cap.
I had built a vacuum manifold out of an old Mr.Gasket fuel manifold and mounted it horizontally just above the top of the block at the bellhouse connection.
I had already plumbed the intake manifold with -3 tubing and t-fittings in series.
That runs to the vacuum manifold and is what supplies the vacuum to my system.
The PCV valve and catch can are plumbed to the other side of the vacuum manifold.
The vacuum manifold also provides other vacuum connections like for the vacuum gauge.
You can't see much of it because it is tucked against the header heat shield.
I also machined the driver side valve cover to take the PCV valve there in the back of the valve cover v, the original location in the front and plugged the original front port.
This way it is all more accessible to the back of the engine.
