Craig,
Thanks for reminding me about your LH bank problem. That fact had slipped my mind, but does possibly point to the cat also.

Marc,
Thanks for chiming in with Graham's commentary. Excellent information. My recollection of that discussion somehow visualized significant chunks of broken catalyst getting back into the cylinders. Now however, I can more readily visualize loose, broken catalyst being pulverized and then, even more easily, being transported to the cylinder during reversion and distributed to all cylinders on that bank over an extended period of time, therefore affecting all cylinders similarly.

Just goes to show how valuable these fireside chats with the experts really are.
