If you are getting high Iron from the sides of the rods the engine is already doomed. They will rub and rub for quite a while before galling and transferring material. Dont really be concerned with it, I do not feel their is anyway to pick up on it by a OA.

I can't say as I've ever seen an engine fail for a rod side clearance issue...... The bigger issue we all pointed out with rod side clearance was yet another area where oil flow was being restricted to the rod bearings.
Tight side clearance doesn't allow the oil to get out of the bearings and it was yet another area where BMW messed up on the design. The tight side clearance in the S65 is an issue, however, it is not such a great issue that it needs to be addressed. If one was doing a rebuild then addressing the side clearance would be a given but I don't recommend anyone taking an engine apart specifically to address it........ Replacing the rod bearings with bearings that address the oil clearance issue is going to be all 99% of these engines need.
