Further, as we all know, the N54 guys are battling CBU as well. Since those engines don't have to combat soot, one would suspect that while the prevention of EGR is good for our diesels, it's only half the equation. To completely eliminate the chances of CBU of any kind, one needs to eliminate the EGR, and take steps to reduce oil from finding its way into the intake manifold, correct?
Thanks,

Gasoline engines produce particulate matter, often in greater amounts compared to diesels:
