I have noticed while shopping around PCV oil/air separators that the only one specifically made for 2 valve 4.6L is the Moroso unit with the drain on the bottom (which I have already ordered). The Steeda kits and other various brands are designated for 4 valve only and appear to mount in line from the left valve cover instead of the PCV line on the right side valve cover. What is the deal? Can you splice in the separator on the left side and it work on a 2 valve? Does it have something to do with forced induction? Is there any benefit to running one off both sides? My desired end result is no oil blow by into my supercharger or anywhere for that matter. I also noticed that the supercharged generation of the Ford Lightning (which are 2 valves) have the left side oil separators available to purchase.
