Oh man this is the very next thing on my list of things to get. I should have listened to @DoubleD a year ago and got one, I'm over 30k now so I bet I'm going to need to clean the valves out.
This is what my PCV can caught on a bone stock 2016 in 1200 miles. Installed both my cans at 300 miles and just did my first 1500 mile oil change. Valve cover/turbo inlet can was dry but so were my pipes so no complaints.
