From my understanding the cylinder sleeve dis-forming (shifting and etc) was a early engine problem... the cracking is a new problem that has started to come along now that the early 3.4's (from 996), 3.2's and 2.7's are getting up in miles
I wouldn't say this is a big problem, as I would guess a good percentage (25% or so) will get on a message board to tell their story... the M96 engines do die... but a lot of engines die too....
