My oil burning pig. Pics too!

Well, the oil rails (the upper and lower thin parts of the oil rings) don't typically have much tension by themselves; the oil ring spring behind them is what puts the pressure on the rails. So make sure you are looking at the whole oil ring assy, not just the rails. Make sure the oil ring spring ends have not overlapped. That will take all the pressure out of them; and you usually need to replace the springs if that has happened.

Look at the 2nd rings and see if they are oriented up correctly; either a dot or some marking. 2nd oil rings usually play an important role in oil control.

Check all the ring side gaps in the grooves.

Brown sounds OK. Glazed is smooth and shiney, almost mirror-like.
