Would my best option be to run one side with a breather, and the other side with a PCV valve going to the back of the carb? I would have to run an open system because my air filter is open and does not have a place for a second hose. Also would the side with just the breather, be likely to get oily or residue from the escaping gasses on it? Thanks for any info!
I have an older 327 that had the draft tube that I used for the filtered air from under the air cleaner pan and used the oil fill in the intake for the pcv valve vacuum. I have had the valve covers of and clean as new. What ever proper pvc system you use and good oil and regualar changes you will have a clean vlave trian. Ed ke6bnl
