new CCV solution from SPE
as my luck has it...as soon as I pull the trigger on something, a new idea or offering comes out.
SPE has a CCV hose to tail pipe kit using their cheese grater screen and a new fitting that goes into the tail pipe. dont know if the fitting needs to be welded or if it is bolt on. sent an email to ask.

Just to be clear, that site is to SPE Labs, and not SPE Motorsports (that sells the CCV recirculating box product): https://spediesel.com/collections/po...7l-powerstroke
However, SPE Labs does have an interesting product. Makes me wonder, though; after running and sitting, wouldn't oil that could slowly drip into the exhaust pipe, what would be the result of hitting that oil with ~1300 degrees of heat during regens?

I reckon that you could run the hose from the engine to a catch can (to condense and scavenge the oil) then run a hose from the output port of the can to the bung that's placed into the exhaust pipe. This way you'd only be burning fumes during regen and normal exhaust flow, and not any residual oil that might collect there.
If I was to do this I'd install the bung far downstream from the NOx sensor, so as not to damage it or produce inaccurate readings.

To each how they spend their own money but that is a Chinese rip-off site from SPE Motorsports. Particularly, SPE Labs has stolen directly from SPE Motorsports, the "internal catch-can" shown, as well as other patented material. As such, I call this sham company out whenever I can in hopes to drive business away from them.

I asked our mechanic at work ( he keeps a large fleet of diesels on the road, I trust his opinion) his thoughts on running the CCV reroute to the exhaust, and he advised against it. He says many people have reported oil coming out of the exhaust, covering towed things like a trailer with oil. We have a 5'er... I have no interest in cleaing oil off it all the time. The other thing he mentioned is having enough vacuum to actually suck more oil from the engine than the CCV reroute would see without the vacuum.

I ended up running the SPE Motorsports internal catch-can along with their CCV re-route even though I have a 24 and had the new stock CCV box; after 2500 miles, I can say that my charge air pipes, TB and intake have stayed cleaner and do not have any noticeable oil in them. I cleaned everything I could as I installed but won't know how well this setup works until I have about 15K more miles using them. So far though, I am pretty pleased with that setup.

Ugh sorry for my typo. I meant recirculating solution not reroute. I modified the end of the hose from the stock CCV box and attached the SPE hose coming from their box so it attaches just like OEM. Using a trim removal tool (credit to PTT w/ ARod) that is a breeze to do now.

that should work well.
there is one case of an owner reporting to spe that his truck fails the oil cap fill pressure test if he has the screen installed but passes if he takes the screen out. dont know the out come.
re: the internal catch can ....there is two ways to install...one way it does nothing...the other way it does what it cliams...the install is not very clear on this....if you look close at install pictures and videos...the hole that goes to the exit tube is basically in the corner with the sheese grader screen in between the exit hole and the crank case which is the right way vs the opposite in which the cheese grader is in the corner and the exit hole is in between the cheese grader and the crank case and in the later the cheese grader does nothing.

I remember reading about that and it struck me as odd but something to pay attention to. I created a sealed oil cap with a barbed fitting so I could run a tube to my manometer.
I’ve done a couple runs with the manometer hooked and the max I’ve seen CC pressures hit was 4.28 inches of water when cold, and -5.8 under heavy acceleration with a load for a few seconds. I did the same with the factory box prior to swapping and found that the positive side was about 1.x lower but the vacuum only hit -3.4 which I attributed to the check closing whereas the SPE box does not have it.

Uhhh, it's not a contradiction at all... the exhaust bung causes TOO much vacuum and sucks excess oil out of the valve cover and into the exhaust system and out the tailpipe. Where did I say there wasn't enough vacuum?
