The spec for a CM871 is 457mm (17.9") on the official cummins gauge. Personally, I think it is way too lenient and there would be no way you could keep a DOC/DPF can happy if that blow-by is from the piston rings and oil consumption was occurring. I would think that oil consumption resulting from that much blowby would likely be high enough to constantly face-plug the DOC all the time.

I also find it curious as to why the blowby in that chart follows the boost pressure specifically, and not the RPM, torque/HP, or any other factor. -- Interesting.

could this be an indication that the turbo is making some of that blowby?
