hope you've been cleaning your air filter...or get a better air filter for that matter. Mine used to look like that until I got a Amsoil nano filter and no more dirt.
That's the MS3 PCV system for ya.
No... well... yeah. It's bad; everyone's is, but there's no current fix for it now. As far as I know, Mazda is working on an update. For now, a catch can would help.
Just be sure to recirc the valve and take care of your baby for the time being. A catch can should mostly solve the build up problem and make everything right as rain. I've heard release dates as early as this summer for the revised PCV system.
