The two things that you'll want to check are that the check valves are facing the right directions and that the plug-and-play connectors for the PCV ports are fully seated. That's generally the most common issues. Secondly, some trucks (for whatever reason), just don't produce a lot of blow-by, and in dry climates where there's not a ton of ambient humidity. Give those fixes a shot. If you're still having issues, shoot an email over to [email protected].
