Luis, I have followed this entire post as well and just read through the 13 pages of it in 3 HOURS!!
I am having the EXACT same problem on my build and have made a few posts of my own recently. I know you haven't replied for a while now but I would love for you to fill us all in on the status of your engine and if you found the culprit for the burning oil. I am in the exact same situation you were with my build and I would really appreciate hearing from you to find out what the reason was in your case.
Hope you still visit this site and see this!!
