With the help of reklund on this board, I rebuilt my motor and burns absolutely no oil during 3-5,000 mile oil changes, with regular driving, however it sometimes looses a little on wheelin' trips. Usually with the 22r the valve seals go out first if you run it low with oil, and from that point on you can count on burning more oil. I wouldn't worry about losing a a quart every oil change though, just make sure it gets added obviously
