I'm working on solving a similar problem on Cat C7. Unlike your Cummins the early C7 had problems with too much blow by from the side breather. I've rerouted the breather up and over the engine to give the oil more time to drain down, but have not put enough miles on it to see if this helps.
ASSUMING it's not overfilled and you do not have excessive blow by because of dirt getting into the engine (check hose fittings between the turbo and air filter) I would make a oil trap. Route the slobber tube into the bottom of a large mouth plastic gallon jug filled with steel wool. Replace the steel wool at every oil change..$10.
This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.
