It is normal for a certain amount of crankcase gases (smoke, steam, whatever you want to call it) to come out of the breather tube. This problem is part of the '07 emissions for on-highway diesels, the '07 engines have a closed crankcase (no venting fumes).
If the gases are excessive... repair the problem. Actually, what he has done with the breather tube may actually compound the problem.
Under high exhaust flow, his crankcase will be under a high vaccuum
What SEEMS like a good repair... isn't always.
