Were these ring gear teeth marks there when it was first fitted ?
As far as I know the only reason the ring gear teeth can get damaged is during starter motor engagement - which is usually only at high compression points - not evenly spaceed all the way around on all teeth- besides aren't they damaged on the wrong side of the teeth for starter motor engagement wear.
The ring gear is not clipping the rear sump bolt is it - with a bit of end float in the shaft moving it clear when the motor is tipped over ?
Seems unlikely but worth checking.
