Oil from CCV, what does it really mean?
#16
Oil from the CCV doesn't necessarily have anything to do with blowby. Voodoo I can't rule out.
Since it's piped to the intake, boost has something to do with it. Plug up your air filter with a bunch of mud and guess where the turbo is going to pull air from? If there's not enough free flowing air from the filter, it pulls it from the CCV. Once you start sucking air from the valve covers, oil comes along for the ride.

So it has been debated in other threads about the ccv being vented to the intake. A guy tore his engine on the sd forum and said that their was alot of build up around the intake valves. Not sure if that's a bad thing but it would collect and build heat and eventually cause a slow down in air travel. Most cummins and fleet 444 int. engines are vented to the atmosphere. Just thinking there is a reason they don't vent it in the intake. I'm thinking of routing mine into my exaust to see how it works.

I just changed the 6637 about 2 weeks ago and just to check I pulled the rest of the intake to see what it looked like, and suprisingly it was fairly clean.
The only thing I can figure is like you said, when the intake gets restricted the truck starts trying to breath though the engine.

Justin, correct me if I'm wrong but wouldn't that be more likely to suck oil directly out of the V/C's without some kind of screen in there? Especially when under boost?
I had mine vent to atmo, but got sick of the smell, smoke, random people telling me my truck was on fire. Back into the intake it went. Heck, I'll burn anything I can suck through the engine... wasted energy as atmo vent
I clean mine about every 5-10k, whenever I get around to it. You can tell it was dirty if you check the before and after on the dip stick smoke. The level goes way down after cleaning out that screen. A can of brakleen seems to do the trick.

The CCV sucks oil vapor out of the motor.
The screen catches the vapor and it solidifies.
Eventually the screen collects enough oil vapor and the turbo sucks this oil into the intake because the screen is dirty.
So, if you removed the screen, it would basically be sucking strait oil vapor with nothing to catch it. Thus just defeating the purpose all together.

about 1 dollars worth of gas or 3 dollars worth of brake clean. haha. I can wash more parts with the gas though also. So i just use some good ole petrol.
I just plug the holes iwth my fingers and swish it around. Use the air hose to clean it out.
I have the appearance of no blow by as well when that sucker is clean.

I originally had mine vented to the atmosphere with the metal filter, but when I put the different turbo in I had to redo the doghouse as it was in the way. I'm currently running it straight to the atmosphere without a screen.
It doesn't smoke anymore than it did when the screen was in there. However, it does leave a spot in the garage...
