I belieive it is much more common in these engines than any enthusiast would like you to believe.
I hope the rebuild market has figured out how to cost-efficiently build thee bottom ends. It's not something I can spend the time learning.

So what normally causes it? Worn out rod bearings or are the caps stretching?
I believe it is normal to reusing rods and caps in rebuilds, with undersize bearings and a crank grind if necessary. Out of round journals are the most likely culprit, IMO. The 2.5 pack quite a punch on a short stroke.
Splitting and re-splitting the cases and "plastigage"-ing the journals seems like a half-baked way to rebuild these. It would either take some crazy high tech micrometers or a perfect touch , neither of which I have.
With the case bolts threaded into aluminum, the bolt stretch may have to be done merely by expert hand.

Drop a 2.2 in it and save yourself some trouble.
