CFM OIL BREATHERS

[Swannyvill]

I am looking to get the oil breathers set up. Just wondering anyone else has done this on and if they just blocked off the 2 pcv vents and just used the oil breathers oil cap. I was planning on getting the one that includes the catch can since i am FI. If i were to block off those ports what are people using? Thanks

I don't think you can cap off the PCV openings in the valve covers. The CFM breather is only open at WOT. The breathers are needed to vent at part throttle.
