I tried to be cognoscent of this, but with such long runs and a only a few inches of "height" difference between the two 90* elbows, it's nearly impossible to have constant slopes with no hi/low points. I'll be keeping a close eye on it for any blockages, and monitoring the catch can regularly to ensure that it's collecting oil at a fairly constant rate.

The purpose of a catch can is to separate out the oil vapor that is part of the crankcase ventilation system. In these diesel engines the oil vapor combines with the soot from the EGR system to form hard, nasty carbon buildup in the intake system. By removing the oil vapor from the crankcase air before it gets to the air intake, it will help prevent much of the carbon buildup.
