at last count by an M96 engine internals expert. None terribly probable. And no way of knowing much until someone who knows these engines examines the carcass.
Your replacement engine is out of warranty (2 years parts warranty in the US for replacements IIRC). Porsche may do something for you if a dealer goes to bat for you and if you are the original purchaser and have had services all done by the dealer. But it won't be much and it won't be under the warranty but rather goodwill so a friendly relationship with the dealer is your only chance.
25k on the engine since 2006 means it is pretty close to a low miles per year situation and those aren't great for the engine.

Sorry to hear of your troubles.
