Yes I still use PCV, I found the Catch Can a pain, so no more.Do you still run the PCV? That's where it makes a huge difference. With the IE valve cover especially as the opening is much bigger so there's way more vapor running through all the time not just when your on the gas. I was losing about a quart every 2k miles and that was going straight into the intake as vapor.
When I was making my Home Depot Catch Can, I read this Article.
This Article is similar to your setup.
