Run down to a no limit catch can then out to a no limit Venturi in the exhaust

Any issues with just running the ccv to atmosphere, besides smelling possible oil fumes?

That's what I have. You just have to drain the catch can every 5-10k

I ran a CCV on my 6.0 for about 3k miles worst thing I ever did.. never had a drop of oil on the ground. Then did the reroute and boom oil leaks everywhere.. put it back stock and fixed the O-rings/gaskets that we’re leaking and not a drop again. Believe that the CCV can’t get rid of the crankcase pressure like it can when it’s being pulled back into the intake

I run the absolute performance Ccv kit to atmosphere - no oil drips and no leaks.
I had the spe ccv kit and oil was everywhere is you even remotely ran it hard or towed.

Weren't you originally experiencing the same results - no oil drips and no leaks - with the SPE kit?
What's the difference between the two kits to give different results? Is it because the Absolute Performance kit has a self servicing catch can canister assembly, with a integrated baffling chamber?

That’s correct... I didn’t get drops from the spe kit for the first 1500-2k miles. Then I had a trip through the mountains and some gooseneck towing that made the truck work harder and drips were all over my parking spot from then on.
So far, still no drips with the absolute kit and I’ve pulled a few heavy loads with it as well.

The CCV mod is a terrible idea on any vehicle. On a closed system you are simply burning the blowby oil mist. That's it. A diesel is an oil burner by it nature. Plus you get the added benefit of not smelling the noxious stinky fumes. On an open system you increase your chances of something getting blocked, either by insects, critters, ice, damage from road debris. Seen all the above on stationary generators that vent to the atmosphere. This is one of the reason Caterpillar is now offering CCV kits on its new generators. End of day this is a step backwards. It's similar to saying a draft tube on a 283 Chevy is better than a PCV system. It's not. Your asking for excess crankcase pressure and leaks.
