Bill ,
I would be pleased to try this. My engine is still out of the car so the timing is perfect.And my engine already has one of your pistons ,so whay not an AOS also:-).
I am apprehensive/puzzled why others have not already tried this upgrade. The modifications are simple,inexpensive,require no special tools/skill .
The AOS problem has bedeviled the M96 community for a long time ,so can it be that only Brad Roberts has this solution?Perhaps he just substitutes a complete BMW system? see links below.
The BMW AOS/vent system may be more durable than the M96(??) but it still causes adverse comments on Beemer Forums.
I would try one but am confused about the quality. Some are $50,others $150:
