Does that fancy valve cover have a baffle in it to shield the PCV? It looks to me like the PCV is sucking up way too much oil. Could be as simple as a missing or misplaced baffle or perhaps a faulty PCV out of the box. The Lightnings used a different PCV due to the placement of the PCV in the lower intake versus the passenger side valve cover. I have seen issues using the standard PCV when using that intake. Probably does not apply to your situation, but something to bring up.
I will for the sake of it get another Motorcraft PCV, why not with all the money I have wasted lol. I have read some stories about people relocating the PCV to the large port on the T on top of the intake but not sure what thats all about...Maybe I need to look into that more...

Clean out the oil in the intake and replace the pcv valve and clean or replace hose and see what happens. I would think it would tend to get sucked down the intake before getting up to the throttle body, but the edelbrock intake has that slope down to the TB so that may be why it is building up there as well.
On the regular truck efi 5.0 and 5.8 Ford originally ran the pcv to the rear of the upper intake, (like the edelbrock does) but the crank case gases were sucked down the 4 and 8 intake tracts and not the others leading to issues. The system was later revised to move the pcv intake to a more centered position on the upper intake to distribute the gases more evenly.

I can definitely try that...quick note on the heads, they are new reman units from rock auto but anything is possible. Same for the intake gaskets, new Mahle units but again anything is possible!

PCV not an issue, did what you said and still no good. I also tried the IAC spacer that I saw a lot of people talking about, it seemed to help but now it just idles high, I tried to adjust it but still when it coast it surges and dies. Now the check engine light came on and says o2 reads Lean, not sure if I burnt it out??
Vacuum still reads low about 15. Which says timing late but it’s spot on. Another note, when I unplug the spout connector it seems to run better...
What a mess....

Is it still pooling oil or it just didn't fix the tip in problem?
Did you check the operation of the timing advance?
I don't know much about timing on these except what I have witnessed on mine- as follows:
Time to 10 btdc (base timing) w/ spout out
no advance when reving up w/ spout out
spout in:
36 btdc advance while reving to mid 3k rpms
unplugging the spout takes the computer advance out of the equation

To be honest even through all of the frustration and complaining I would say yes. I love the way it sounds, it pulls really nice. Part of me wishes the truck was a 1/2 ton and not a 3/4 but I still love it. I have had a habit of making a small project out of something and then down the road getting the itch for another one so If you know me it’s happened before haha. If anyone is ever in the Chicago area and wants to see it or take it for a ride let me know!

Another note I should mention, just having the engine bay uncluttered and open almost makes it worth it as well.
One note I also wanted to share, not sure if this helped but I also at the same time as doing the EGR decided to relocate the PCV. I have the brake booster connected to the back of the intake and the PCV comes up to the T where the booster used to connect.
Now that I have some time, once I get my post completed about the build I will post up and link here.
