As said- if it is a CAP. Not a breather/cap combination. That's why the filtered fresh air was also mentioned. Sorry if this was not clear.

XNTRCI-T You do not want to combine a breather and a PCV in the same cap. They will, in effect, cancel each other out, and the nasties in your crankcase will not be sucked out. The PCV and breather need to be separate and on opposite sides or ends of the engine to get a cross-flow through the crankcase.

Here is one of the better explanations of positive crankcase ventilation I have come across.

Yes, you can put the PCV out on the end of the tube, in the cap- if you so desire. It would seem that this set-up would be unsightly, but perhaps I'm not envisioning it as you will apply the idea.

Don't forget to bring in filtered air for the other side of the PCV system.

About to start assembling 350 chev motor for my T - C cab project, I have an edelbrock twin 4 manifold with carbs this has a breather tube hole in the front, I was thinking of putting perhaps a 6" length of tubing coming from there and topping it off with a breather type cap, is it possible to incorporate the pcv valve in the cap ( this would keep everything neat) A friend has told me that I need to drill and tap a location for the pcv near the end of the manifold (near dizzy) so it would work better. My tappet covers have no provision for these items.
