Hey there, I just bought one too, I'm getting same codes and I use same "Creader". I finally got time to check the pcv because dealer I bought from said they replaced it because of check engine light. On my 2016, there was some sort of insulation material, foam covered with plastic/rubber around the supercharger (SC) and the dealer I bought from had closed the pcv onto the material

Looks like they tried to cut it up and pull it out but failed miserably. The clip on side under the SC was bowed out from being pressed onto this material and caused the leak.

You might check that it was installed properly first, or have your trusty shop take a good look at it before moving on to valve cover replacement. I've never replaced a valve cover/ gasket less than 150k miles unless it was messed up on install, they aren't the kind of thing that wears out under 100k miles unless defective.

*Update* we just drove about 80 miles after doing repair this morning. No check engine light and I realize now the idle was wonky, it would fluctuate rpms about 200 rpm up and down with AC on in park or drive, now idle is steady again.
