Instead of doing a compression test, do a leak down. If you're blowing that much oil you might have a bad ring/rings that are not sealing. Its not uncommon to have good compression and have quite a bit of blow by.
Do this..... at an idle with the pcv in, vents plugged, see if there is vacuum at the the oil fill. If there is fine. Now do the same thing at lets say 2500 and see if there is vacuum.
