I ended up going with the SPE Motorsports Recirculating CCV box. I installed it last night, and other than the hose that connects to the intake being way too tight and an inch too long and hose clamp not being big enough, everything went smoothly!

 

I would have sent the over priced item back,............... especially with the issue you had. That is uncalled for, so much for R&D.

 

Well, I could have done that, but this solved my problem... and any other options have their cons too.

 

Overpriced is a bit subjective I would say but respect the opinion. I have the internal catch-can as well as the recirculate solution on my 2024 6.7 HO. It was easy, at least for me, to put on, and it works very well. Depending on the ambient temps when a person installs the hose, the best bet is to have a bucket of hot water and let the hoses sit in them while removing everything else. This relieves the stiffness and makes the hoses more pliable for install. I also used a small amount of lubricant inside the ends of each hose, and they went on with a little bit of effort. As I said in a previous post, I modified the hose from the original OEM CCV so that I could attach the SPE hose to it and fit it right back on the intake nozzle without using a hose clamp. I've been very pleased with the crankcase pressures as well as the extreme reduction of oil in the CA tubes on. Once I replace the full air intake manifold here in a few weeks, it will have a good chance of not becoming occluded with oily soot.

 

Wow... Nice work... you mind posting a pic?;

I run the stock box. First ran the Mishimoto CCV catch can, which places adapters under the stock box. Just like SPEs CCV reroute adapters where the front port is plugged off and rear port is used to send the CCV gases to the external can, Mishimoto's front adapter blocks off that front port and their rear adapter picks up the gases, sends them to their catch can, then sends them back to the stock box as "filtered" gases and then on to the intake...

I then found Improved Racing's CCR catch can, made with large -12 ORB ports, made for induced engines. I am using the CCR can with the Mishimoto adapters still mounted under the stock CCV box. I bought the 0.5 liter can and have it sitting on top of the engine bay fuse box (on top of a piece of thin rubber pad for protection of the fuse box lid).

Started looking at SPEs internal catch can and wondering if it would be possible at all to use with my set up and add it to the Mishimoto adapter there... I am also thinking of replacing my stock CCV box with SPEs recirculating CCV box so I can take it apart and see how well my CCR can is working.

Improved Racing claims up to 90% filtering efficiency with their CCR can. Plus I'd like to see what the inside of stock CCV box looks like as I would cut it open and have a look. But I wouldn't be surprised to find a decent amount of oil in it because the Mishimoto can, which Improved Racing tested (they tested about 5 IIRC and labeled them with letters... don't believe the highest rated efficiency was above 60%).

Anyways, a pic or two would be really cool. Thanks.

 

Soon as I get back to the house I’ll take some and post back. I’m interested in what you are describing above as I am always looking to remove the oil vapor and soot from the system. Anyhow, I’ll get some pics on here shortly.

 

 

@Overkill2 Here you go. I forgot I had a few on my phone. Please excuse the engine uncleanliness, I’m a bit embarrassed. If there’s a different angle or something specific you want to see, let me know and I’ll snap it.

 

If one WERE to install this system, make damned sure you put the bung AFTER the DPF! You don't want oil vapors accumulating the the filter, especially for Pre 9th injector models. Besides the extra "fuel", it can damage the ceramic filter.

 

@pkarhoff Thank you... I see what you did there and great thinking....

I do not think I NEED the internal catch can but it would be cool to run it... I will provide more info and direction for you on my set up when I get a chance.

As to being embarrassed about your engine, DON'T BE... living in the rust belt, I get an light oil treatment every year, Carwell Products, and it's dirty AF not only under my truck but under the hood... no worries brother...

Pics will prove it, you'll see...

 

I mean how can you resist installing the finest weapons grade chinesium bungs on your exhaust?

The 16mm hose they provide seems a little small for the length of this run, especially if your running this on a OEM emissions compliant truck. 19MM, 3/4 or -12 would have been better options IMHO. Also having to run the hose over the driveshafts or up and over the engine seems like a pain.

 

Did you install the exhaust scavenger into the stock exhaust pipe? I have a 2018 with exact same setup. Installed the scavenger after the DPF, but can't get a vacuum. Appreciate a reply on your setup and how it is working. Thx

 

have you tried turning the whistle style fitting 180 degrees?

 

I installed mine after the DPF on a stock exhaust. I tried slowly rotating the bung every which way but no joy. Will try a second install after the rear axle and before the exhaust tip. Thanks for reply.
