I don't think the 6.4 intake is set up for an external PCV set-up,the truck 6.4 uses an internal PCV set-up. I think you need to mod the 6.4 intake to accept an external PCV set-up.Check with CrazyKid on here,or head over to Tuned Rams or High Performance Rams on facebook,you'll find more guys over on those 2 facebook pages to help you out with the intake swap.You'll also need one of Takyami Sams(spelling??) SRV (short runner valve) extension harnesses if you want a plug-n-play harness instead of lengthening the wire harness the old way of soldering and shrink tubing the wiring.You can also buy Sams harness through MMX now.Have you picked up a EGR block-off plate,or are planning on building your own,i think Matt at Moes sells the EGR block plate.If you plan on keeping your 5.7 injectors you'll need spacers for them,if you want to run the 6.4 injectors,you'll need a custom tune for them.
Ah yeah, that's right, I'm an idiot, completely forgot the 6.4 setup was different with the pcv. I haven't seen anything about having to modify to an external pcv setup. Is that even necessary, or can I just cap where that would plug into the S&B? Only pcv mod I recall seeing in regards to this swap was the guy who was modifying to fit a catch can on and he jb welded the hole that led to the intake from the pcv port (pic below). I'll have to do some more digging around on this swap before I attempt it this weekend. I don't do the meta facebook haha. This would actually be my only social media account lol.
I bought from Moes, got the egr block off, extension, and spacers. I guess Matt carries the ported ones in stock, because I got it in 3 days, which I was totally not expecting. I've also got a spare MAP sensor, so I'm going to swap that with the one that came with it and trim the manifold down to fit it.
Also just ordered two new injectors and going to swap those out. I may have a couple dead lifters, so I figured I may as well put the 6.4 intake on while I pull the manifold and valve covers to check. If the injectors are good and I end up needing lifters and cam, I'll just throw the 6.4 injectors back in.
Funny thing was that I was actually thinking about getting rid of the truck since I'm nearing 100k and prices are so high. But with a potential catastrophic lifter issue, I'm certainly not going to pass the trash to someone else. If lifters and cam need replacement, may as well go performance, and I'm certainly not going to want to get rid of it after adding 100hp haha
