Cummins N14 catch can?

go to a junk yard and get another cover with a breather and run a second one

 

You are a smart Man, you're getting it. Up until a number of years ago, there wasnt very many things me and a decent Kid couldnt do to a truck or piece of equipment. I still maintain two shops and still like to work on stuff occasionally. But we all know time is money, and its so much quicker and easier for them Boys to do the important things that need to "get done".

 

Fortunately I have a really good Mechanic/fabricator who does work for me on the side from his full time job. He has a take home shop truck with welder and every tool needed to fabricate anything my rig usually needs. He can do in an hour or so what would take me several hours to do.

 

Best one I saw was a piece of 4" PVC, caps on both ends, small ball valve on bottom cap to drain and a nipple on top to connect hose along with a axle vent. Whole thing was 20" long or so. This was on a worn out Cummins 444 years ago, but it would work for your issue as well.

 

When I had my FLD with a 12.7 back in the day I just cut the top off an oil jug and hung it from some wire with the blow by tube going into it.
