[Wife's Boxster S]

Wow!!! Just learned of this issue with the Boxster engines. My fault for not doing my homework before buying. I've got 118K on a 02 Boxster S. Are there any signs to tell me the bearing is going?
Should I try to sell it before it happens (if it hasn't already)?
I do have some experience with engines, I rebuilt a Volvo B18 in my P1800, when I was young and eager with lots of time on my hands, with good results. So is this something that can be tackled without being an experienced tech? Help!!!
