Looking for some input. Currently have a dual snorkel air cleaner assembly that is set up for 2 breathers. Options as I see them now:

1- breathers in each valve cover and an intake mounted PCV
2 - breather on one cover and PCV on the other and cap the hole in air cleaner
3- breathers in each valve cover and no PCV

Do one of these options clearly stand out as a better choice for performance?

 

The factory used a plug in the second hole in the air cleaner for cars that didn't have dual ventilation. There is no reason not to run a PCV valve.

 

Thank you and the simplest and easiest solution.

 

I have your set up and this is the plug that I used:

Thank you

 

One other cat skinning idea. I drilled a hole in back side of oil fill tube, used generic Mr Gasket grommet in the tube to accept PCV valve. Dual valve cover breathers. I partially retract the valve so long neck funnel goes past the grommet when pouring oil.

Interesting and thanks for the idea
