N14 oil crankcase separator

[Kid Rock]

Got a little oil drip coming from the blow by tube on a n14 celect plus. I'm just putting this truck on the road. All is well, runs strong and fairly efficient. Had to fix oil leaks at all three cam followers and thought I had my oil leaks under control. Well I've spotted the slow oil drip out the blow by tube. My two thoughts are that 1. I have to much oil in the system ( unfortunately I had to let a local TA do it and he didn't seem to familiar with the N14 )

And or 2. That the crankcase oil separator has failed, allowing oil to escape

I found theses that fleet guard makes. They're a little over $500 but I'm not for sure if they do the oil separating as well

Any thoughts on this matter?

Thanks in advance and safe trails
