More intake crud

Okay just got done watching this video. Anyone know how they put it in a new SCR section on the rocketship? I thought it was all one piece.
And thinking about this fritz, this problem was caused by the EGR injection into the intake. The problem was not caused by the CCV. But with that said, I still think it's not a bad idea to filter that crud out of the CCV reroute back into the engine with a catch can.
And thinking further, the new 20 6.7 engine uses less EGR (but more DEF) than our trucks, the 11 to 19s, do. So maybe that's why some go out way further than ours due to less sooty intake charge coming into the engine.
Just thinking out loud is all. Who knows?

I do like the idea posted earlier about moving the EGR bleed off to after the DPF....dont know if the temps would be adequate for all the emmissions magic.

I wonder what the flow rate would have to be to steam clean those intake passages...and/or ideal placement of spray injectors. too much flow rate and you get too much cooling which when coupled with b5 fuels...could drop egt temps quite a bit. I wonder what the 6.7 world would look like if a spray injector was positioned in ideal crud prevention places.

I think Ford did something with the latest gen of 6.7s, MY 20 plus, by using less EGR and more DEF in their engine/exhaust emissions strategy.
Thinking about methanol injection, wouldn't that be a cool option from the factory for the guys who wanted it? Backed up by OEM research and development along with a factory warranty. Methanol injection has already been proven for performance gains since WW2 and does keep the intake/combustion chambers clean.
Ford is on top now when it comes to power but would go way over the top with methanol injection, could potentially keep the truck more emissions friendly, therefore make emissions equipment last longer. But there are those pesky bean counters.

I have the SPE CCV reroute kit installed with internal cheese grater, extended the hose to the rear of the truck, but too do not like the little bit of "smoke" coming out at idle. Have a Mishimoto HF catch can on the way and I think I will put that on the frame behind the front tire and route back up into the intake. keeping the gases in, but the oil and crap out.

I cannot speak for DEF usage on anything prior to the 20 MY but I know when I went from MA to FL back in November I had a full tank of DEF when I left and I had to fill it when I arrived in FL 3 days later. I was towing my 5er , about 13k the whole time and I used roughly the same ammount of DEF on the return trip.
