Ok guys i am going to go eat dinner now i am out have fun with this hope yall learned something.

Heipps you more than welcome to give me a shout if your having any doubts man. I can walk you through the whole process in about 5 min. 2252789895

this has gotten way more complicated than it needs to be.... route it however you want just DONT put it back to the turbo as a catch basin.

the only reason you see oil in these ''coffee mugs" and in your turbo is because you give those vapors a place to condense... if it is straight hose those vapors just escape and disapate.. its not like there is oil just dripping out of the hose

It's not a "big" problem, but it is a problem. I guess you missed my point about "excessive" blow-by being abnormal, which it is, and if you have enough blow-by to NEED that much airflow the CCV is the LEAST of your problems.

Bzzt, nope. Again, the vacuum doesn't PULL the pressure out of the crankcase.

Here's how the 6.7 CCV system works according to the FSM.



Cummins refers to the CDR as a "Crankcase Differential Regulator" and is actually to prevent pulling oil out of the crankcase under high-vacuum conditions.

Yes, that is correct. If you REMOVE the filter and the line running to the turbo inlet, instead letting it vent to the atmosphere, there is no need for a CDR as there are no concerns about excessive vacuum. Again, it's not VACUUM that pulls the pressure out of the crankcase, the POSITIVE pressure in the crankcase vents itself.

Let us know how it works, but again...you're way overthinking how the CCV works and what its purpose is. It does not require any sort of "vacuum" to vent properly, it just needs a place to vent, preferably someplace where it won't make a huge mess.

I'll try it out tomorrow and if I have any issues i'll give you a shout! So what im going to do is find a plug that fits for the intake (do you know what size?) then take the hose that is currently going from the valve cover to the turbo and run it down how cumminsfirefighter did his (in the pics) and cut to length. Then pull out the ccv filter and thats it?

Yes sir! 3/4" hose and 3/4" plug. Two hose clamps and thats a wrap cap!! Run it at a downward angle infront of the firewall and level with the bottom of the control arm. You want a green bean can cuz?

seems simple enough. And ill pass on the can! I don't think ill put a jar or anything actually, just the slobber hose and thats it.

Lmao!! Okay man!

This was a great read. Thanks to all of you. I'm going to install a K&N with rubber elbow, at the valve cover and a plug at the air intake tube.

I guess my question now is do I use my kit from Glacier or just run a hose to the ground?

if you remove the ccv filter, run a hose to ground. if you leave it, use gdp kit.
