No comments?, We were worring about the oil from K&N filters with out 5.9L's and the 6.7L get all the blow-by into the turbo

 

On the 6.7 the vent runs through a filtering system. The filter gets replaced at regular intervals. They way he did it is completely wrong as it is no longer venting. He may end up with crankcase pressure problems. This link will explain the venting but it isn't the exact model used.

Ok,I never recalled about the filter. He did drill holes into the bottle for venting,where is the filter located on the 6.7L?

 

The CCV filter is located under the valve cover. Big filter, looks almost like a tranny filter. I believe the manual calls for it to be serviced around 65k miles. The overhead will tell you when it needs to be done. My overhead gave the message some time after 70k miles though.
