Long sad story... Opinions on Diagnosis?

Motor had a little over 2,000 km before the turbo's blew. It's 35 even pulses with no skips at all which is why I find it strange. I hope its not the seals lol, they're NRS ceramics. That would cost me more then a new OEM housing o.O

If it was a seal blown, I wouldn't think it would make 35psi in even pulses, you would at least have one face making more then normal, and I doubt all 3 seals would go equally, hopefully just springs are the case.

Well boys and girls, the original assumption was correct. The oil seals and side seals got busted to hell taking the side housings and rotors with them with. Apex seals, bearings, housings are fine but going to need front and middle side housings as well as new rotors for both (My new 20b rotors toast ). My mechanic said he would never had imagined it would be this bad and he has never seen anything like it. Also, was really disappointed because of all the hard work my mechanic put into those ports...

That oil control ring looks like it was installed incorrectly. Hard to tell from the pic, but it appears as it was torn as it was put in. Is the ring still pliable? Oil control rings rarely fail expect due to age, or improper assembly. Side seals mostly fail if clearanced wrong or the port is shaped wrong. Still, looks like you had on oil starvation problem. How are your oil coolers? Was the oil pump replaced or at least inspected during the last rebuild? Make sure the key is there. It is very easy for the key to pop out and slide behind the gear, and you won't even notice.

Another theory from Bryan at BNR Turbo's is that the stock BOV spring got stuck open and the turbo's overspinned and failed starting the oil leak which eventually led to the low oil level causing the engine failure. This theory does seem to match the series of events that took place before I noticed the engine losing power which was the turbo's losing boost and I'd hear a wooshing noise when I tried to go into boost. The boost came back on after I hit high RPM and WOT which at that point is most likely when they overspan and started the oil leak. Again, this is just another theory.
Maybe, once he opens up the turbo's we'll know more of what happened.
