Looks good, but what size are the lines?? You really don't want to go smaller than 1inch (-16 AN ) on the 6.4L CCV.

Thats a good idea. Now if they made it the right size for our trucks. The biggest I seen on the website was 1/2"

[cook03f250]

The 85495 uses 12AN fittings (3/4"). Would that work?

[cweiss87]

I think mine is 3/4 but I got a 6.0. I don't know bout the 6.4 I don't deal with light duty diesel except on my own truck.

it dosent matter what size it is,,,, you can close off the return all togetrher if you want to.... most close off the intake port and re route the breather air out the back of the truck.. this unit would keep you leagal if you care, plus i have heard the open breather line can be smelly.....so in short.... 3/4 is fine.... 1/2 is fine also...looks cool

I disagree. For opening venting to atmosphere, yes, but for a closed loop system with a separator you need more CFM than 1/2 line can provide. Put 1/2 line on your truck in a closed loop and tell us what happens (I'll bet your truck turns into an oil fountain when the crankcase pressurizes.)

100% accurate. Some of us on here are having issues with even 3/4" plumbing incorporated with the CCV mod. I finally took mine off as I got tired of oil puking everywhere. It also increased the oil seepage from the bed plate and my truck was spotting oil on a daily basis. Removed the mod, hasn't leaked a drop since and it would be easy to tell cause they laid new asphalt in my apartment complex 5 months ago.

Well then I would vent to the atmosphere, take the filter out of the unit and use it as a catch can.... Any filtered unit will be suspect as it clogs reducing flow without u knowing until it starts puking.

Venting to atmosphere is the easiest, least expensive route. The only downside is the smell at idle.
