I think that's crap. Barely 100k on the clock and you already have engine trouble? I'd go complain to the dealer.
Sorry... Could not resist...
However: would that type of failure show up on an external check? That is, with routine maintenance, such as valve-clearance adjustment?
Or, if you did not coincidentally pull the head, would you get a nasty surprise without any advance warning?
