Next Sat we have a Flex coming for fitment and to document the install for all.
I also put up a long thread on the ecoboost pcv system issues that covers a common error in most assuming all cans correct the issue when 99% let as much oil past as they catch.
I go into pretty good detail, but if anyone has questions on a specific can, just ask. We purchase every can we see offered. Test it and dissect it to show what makes some work well, and others not worth a dang, so I ask no one take offense if you bought one that still allows as much oil to pull through it and still cause the issues, most make decisions based upon looks and claims and nothing more.
Most of the ineffective cans (remember, all catch oil...it is what gets past a can that is of concern) can be utilized on the cleanside with a RX dual valve dirty side system and work well.
