I have zero issues with the catch can. I just don’t recommend deleting the PCV and routing back between the MAF and TB. If the ARC setup keeps that, then it shouldn’t be a problem.
Minor thread detail. I will add a caveat. I have zero proof venting the crank case causes any issues. It’s just my theory and one that several of the BP guys and I tried finding a way to eliminate several years back. We kind of quit when we couldn’t find a solution. Best I can tell it has zero impact under load. It’s more a idle/drivability issue.
