Default Bhg vs worn rings vs valve guides

Well as many of you have followed my previous issues i have yet one more question before i start ripping my engine apart for my rebuild. Im going to be running a compression test tomorrow, but before i do i would like to know how the numbers should be looking in difference or variation throughout the pistons. Such as. If its a bhg obviously one or two pistons will be considerably lower than the rest, pending how it blew. But if my rings are shot will this look the same? Or will the numbers be a little lower but basically the same across the board? Personally i think this thing is burning waaaay to much oil to be rings. The only possible way i see rings as being my problem is if one of the rings litterally dislocated itself from the piston. I mean i burn ALOT of oil. To be exact probably about a quart in 5-10 miles. I dont know about the rest of you, but that is waaaay to much oil for rings to burn up. Especially if anyone has read the profile on my car recently. Thing is, i wanna rule out hg aswell because i have no coolant issues what so ever, i know it is possible that i could have blown the "combustion chamber to oil galley" but iv heard that it is VERY unlikely to blow JUST that part of the hg. I should mention that it doesnt start to burn oil until about a minute of running. At first its un-noticeable, then after a minute she burns a little out of the exhaust, then when i drive it, it burns mostly from 1-2k rpms while im slippin the clutch driving. I can fill an entire street up with smoke if i wish . Kinda odd for it to be rings after only 30k miles of driving. Especially with no abuse, not seeing more than 12psi, and a proper brake in period.

I mentioned before the turbo went, and i thought this issue was the turbo, but i threw a new one of this last sunday and to all avail, still burns oil. I should mention the turbo was used and had some shaft play, so i mean theoretically it could still be the turbo. But theres just way to much crankcase pressure, cause the day i did the turbo was also the day i blew one of the front seals AGAIN. So yea. Patience is running out, im about to rip the engine out of the car.
