I'm at around 680 miles and I poured the remainder of the 2nd bottle of oil which topped it off. I should be at around 850 miles per 2qt's of oil.
Since I'm consuming so much oil, does it even make sense to change it, I basically do 2 oil changes (by just topping it off) in 3k/miles or just change oil-filters?
Compression numbers looked like this:
150, 150, 152, 151
What should the compression numbers be for an Evo? I'll have to look them up unless someone can provide quick answer

I have two pcvs on the intake manifold side one before catch can and one after. The brether hose is stock on the intake to the side of the head. Its a completely stock system besides the catch can in between and all pcvs been changed for the product tscompusa is using.
Intake manifold , intercooler and exhaust side of the turbo are clean yet all the pistons are covered in oil , where is this oil coming from ? It isn't being materialized there from nothing. The piston-top from passenger side looked like there was a puddle of oil on it when i took out the plug.

Are the ports in the head clean? Just make sure all PCV valve's are installed correctly. You could also unhook the PCV system from Amy boost source and see if that helps. However you should see oil in the intake and piping. Valve seals would usually smoke at idle and under vacuum. A leak down teat like BR suggested is your best bet right now. Since Two shortblock have done it I would say it is external to them.

Removed the UICP and it's completely dry, pre-intercooler is also dry and yeah I never get smoke when idles (unless it's condensation being evapped.).
That's been checked over and over, it's dry in there and yes Turbo's been replaced.

That was on the other TTR block, on this one I haven't done it yet as I'm pretty busy, but if doing it without popping the rockers off will still be accurate, I can probably perform it sometime this week.
I've been driving the car, but watching over the oil closely and topping it off. Though something that is weird is that casual driving, it seem to consume more oil than when beating on it.

I read were a lot of people have built motors that use oil. I don't get it?
I've had two map motors and they burn no oil at all. My current motor has 1800 miles on it.
It has Has been on a mustang dyno, street tuned and me beating on it from time to time. I'm getting ready to change the oil, but I haven't added any. It's still full. I'm running 20/50 synthetic.

If you have oil pooling on the tops of the pistons, I doubt it is the turbo. What was done to the head before/during/after the motor swaps. Could be your valves guides leaking. That would explain oil on the pistons after two replacement short blocks if the head stayed the same other than a deck.
If the head was pressurized and the valves were all closed it may have checked out ok because of the oil flowing in the reverse direction of the pressure check. I am no expert on this subject but it gives you another scenario to look at.
