I just went to a metal fabrication shop and got a scrap piece of 4" tubing- muffler shops should have some too.

Hi, This my first post. New to diesel but have been building gas trucks, cars and boats most of my life. I put together a CCV mod that passes CA smog and removes all of the oil out of the intake tract. I tried the home made PVC canister with every combination and type of scrubber pad but they all let some oil thru. What I did was turn the doghouse around, run the hose over the master cylinder and into a Moroso air/oil separator that I attached to the outside of my Volant air box. I used a 4 inch black ABS union (it is the perfect length and diameter) and glued in a 1 inch PVC elbow that is threaded on 1 side. Cut the threads flush on the inside. I used the green silicone heater hose that Napa sells. I then ran the hose from the air/oil separator to the the union. The 3/4 inch hose pushes snugly into the 1 inch PVC fitting.
I have been running this setup for about 1 3/4 years. Passed CA smog with no problem. It is nicely contained under the hood. I empty the oil canister every 3000 miles (every oil change). You could wipe a white rag through my intake and will come out just as clean as you put it in.

That being said, you can get away with it at some smog shops as long as it routes back to the intake.
A question for you though... What size hose barbs come on the Moroso can? I did a long search for a CCV catch can that had at least 3/4" hose inlet/outlet connections. There were only a couple available, and the Moroso wasn't one of them. You do not want to neck down to a smaller size. This causes restriction, which causes oil leaks.
I made my kit using the Mann-Hummel Provent 200. It has 1" inlet/outlet connections, and costs about the same (if not less) than the Moroso can.
Here is a pic...

CCV mods are legal in CA and do not require an EO number as long as they are a closed system. Here is a similar discussion on this some time ago. Refer to post #20

[QUOTE=Justin@DP-Tuner;14896185]There are currently no CCV catch cans that are actually CARB legal that I am aware of. You would only pass while using one if the tech did not see it, or if they are clueless about how a CCV system is supposed to work. In order to actually be legal here, you would need a CARB EO # on the part.

As you state, the smog shop I use feels it is legal as long as it routes back to the intake and is functional. He passed me when I had my homemade catch can in the system. My system is totally visible and has been checked, inspected and passed twice by the smog tech so far.
The Moroso separator that I used came with 1/2 NPT fittings. I made adapters for the 3/4 inch heater hose to fit. Before the Moroso I experimented with an air compressor style water separating filter. It also had 1/4 NPT fittings. It worked well and pulled a lot of oil out of the air vapor, that is why I decided to invest in the Moroso. It was the only dedicated oil/air separator I could find. Overall, I have been operating for nearly 3 years with filters with less than 3/4 inch inlets/outlets with no oil leaks. My oil fill cap will not blow off the oil fill tube when set upside down. I was worried about a restriction causing excess pressure also, but it hasn't for me. My truck is an '03, basically stock power wise. CAI,exhaust,HPX,coolant filter, oil by-pass filter, external tranny filter, tranny cooler.

I only brought it to attention because multiple retailers/dealers will not ship the BD CCV kit to California since it does not have a CARB EO number.

Good to know on your restriction findings. A few guys I know have used 5/8" hose and catch cans since that was all they could find for oil rated and before long oil started coming out of places it should not have been.
I know there has been research done in that past about this. I am sure it is on this forum somewhere.
