With the starter motor fitted securely back into position by the RAC and only the whirring noise (the starter motor turning) to me, this probably means the pre-engaged starter solenoid is still working, so the pinion should be in-line with the ring gear. Just a personal opinion but if the starter motor has been loose on its mounting bolts for some time, there is likely to be damage to the starter pinion or the ring gear on the flywheel or both. The gears would be trying to ride over the tips of the teeth. The other possibility (although I've never seen it before) is that due to the ring-gear being worn in the first place the vibration has caused the starter motor bolt to loosen. To sort out the problem I guess only an examination of the starter motor and/or ring-gear will be necessary.
