So I take it the build up will cause oil to push through the breather? My baffled had a little carbon but nothing major. Just maybe a 1/32 or less coating.

The cai has a provision for the breather tube. It just attaches to the intake tube.... you have to have filtered air. The easiest way to get around the oil problem is build a catch can. There's a thread somewhere on here about it search oil catch can. Also I found out you van buy the little fabric piece that's in the factory air box through oreilly. It's in the pcv section on the website.
