So I would still like a nice solution to the blow by problem.
I did a lot of research and I found a thread on bimmerforums that sums up a lot of the "tried" solutions. The thread also shows how common of an issue this is.
To sum it up the solutions:
1. Catch can (but you lose the vaccuum on the crank case from the SC)
2. Exhaust evacuation system (really only works well with a catless exhuast and will require bungs welded into your existing exhaust)
3. Catch can combined with exhaust evacuation system
4. Electric evacuation system (this is the most interesting and is used on 03/04 Mustang Cobras... however, electric pumps tend to fail)
5. Electric evacuation system combined with catch combined with exhaust evacuation system
