Curious if anyone is running a catch can on their b58. If so, have you seen any oil caught in it? Newer to the b58 platform and wondering if it's necessary. I like to do maintenance/ reliability mods before I start doing performance upgrades. Is a catch can worth it?

Not heard of this but then my car is only one month old.

B58 rules though.

It does! Same boat, I'm through break in period finally.

I just know on the older n54s it was common to run them because you got blow by through the pcv into the intake side. N55 was less so, but I still ran one on the my n55 car after finding oil in the charge pipe and intercooler inlet.
