Edit: truck is a 2017 6.7.
Is there an interval? all this talk about deleting them, or adding things like Mishimotos separator but all my searching has brought up no answers to if this filter ever needs changing. I know I can order it, but does it need to be changed?

While I don't have an answer for you about the change interval for the filters on the 17+ CCV boxes, there is info on them in this article.
I did a little more searching, the Cummins 6.7 is 67k miles, and I found one post on this board that said they thought fords 17+ 6.7 was 75k miles, but the person didn’t sound too confident that it was correct. Must not be that big a deal either way.
If you take the time to read that Mishi link I provided, it shows that there is a silicon relief valve set up in the new CCV boxes that if the filters clog, That valve opens and the blowby flows directly back into the head. So I wouldn't say that it ISN'T a big deal. The fact is that the new CCV boxes prevent less blowby from the intakes than the 11 to 16s, BUT they STILL LET oil into the intake. JMHO and YMMV...

Yeah I read the Mishimoto thing a couple days ago, I’m sure like everything on these trucks, it serves it’s purpose, and is important, i wasn’t saying that it’s not important, although, diesels have been pumping crankcase gases into turbos since the dawn of time with no filters, maybe a screen and a little housing, but definitely not replaceable filters until recently, what changed that makes a filter important enough for manufacturers to start using them?. I’m curious if there is a sensor in the bypass that will trip a code, maybe that would be the filter change recommendation indicator. Strange that an interval is not mentioned. Or maybe they’re supposed to be self cleaning, the location and difficulty to replace sort of indicate that it’s not really meant to be changed preventatively.
I remember hearing stories about the big trucks just venting crankcase gases to the atmosphere. So I researched here a little. Gas engines used to do the same thing...using a draft tube.
Talking about the diesels or big trucks, it was called a road draft tube. They just used to vent this gases, which also contained oil, to the air. They used a long tube like 4 feet long. Some had sort of a filter on them like a sponge. Aftermarket companies have kits to do this. Why do you think guys are buying these and installing them? Because they don't like that stuff going into their intakes and engine.
Enter the anti pollution age and now it was being sent to the intake to burned in the combustion chamber which was cleaner for the environment but made the engine dirtier inside. I don't know about you, but what the factory considers acceptable is not good enough for me.
The 3rd part of that engineering blog shows the amount of blow by collected for 11-16s and the 17+. The 17+ was less. They redesigned the system for a reason. IMHO, they wanted less oil in the intake. The system does just that...it prevents less oil from entering the intake. But it doesn't stop all of it.
As for me, I choose to keep all that crap from continuing to enter my intake and gum up the works.
As for those filters being self cleaning, how's that supposed to happen getting exposed to all that blow by continuous exposure to it? It was designed with a removable top for a reason. Just my 2 cents.
Self cleaning is just a wild guess, however, the filters are really only filtering gases, to collect the and separate the oil, to be drained back into the engine, so self cleaning/draining. They’re not exactly trapping dirt and grime, it’s just oily gasses right?.
not trying to sound sarcastic, as I really have no idea, just trying to make some sense as to why they don’t have a listed change interval for it.

I have 58860 on mine, I just changed the filter in the ccv and it looks to be way over due. I didn’t find out that there was a problem till I blew 3 turbos in a month. It’s big problem. My best recommendation is to pull the filter and check it. It’s not hard to do, I unhooked the engine mounted fuel filter to give me room and undone the bolts. Pulled the cover and replaced the filter. If yours is still clean you can put it back in and just put the cover back on it. The filter runs 150$ at the ford place part number is 6A777. I think I’ll check mine every 15000 miles now that I’ve figured out what issues it’ll cause. If it’s clogged up you will build back pressure at the oil fill. Mine was bad enough that with the truck running I went to take the oil fill cap off and it had enough pressure to knock the cap out of my hand.
It's the black box behind the engine mounted fuel filter. It's on top of the driver's side valve cover.
This is my truck. I had an oil catch can system installed. The adapters mount under the CCV box which is what the item is where the two rubber hoses go over in the pic. You can also see two white stickers on it. Yours is in the same spot.

thanks for the info, I'll look for it tomorrow, I had no idea it was even there.
FORD is beginning to acknowledge it is having troubles with intake charge contamination. They are not going to come out and say there is a problem across the board and announce they will have a recall. They want the vehicle to go out of drive-train warranty and all will be on the owner then.
There has been a series of TSB's lately for all EB engines. You need to call your dealer and have him run your VIN to see if there is a related TSB. If there is and you decide to take it in, remove all aftermarket catch cans as they can say the system has been altered/tampered and is out of warranty.
The earlier separator with serviceable filter element is being replaced by a sealed unit.
