Yes the "perma-bearing" that Porsche began using after 2004 addressed durability. But the problem there is that it can't be serviced anymore without splitting the engine open, an expense that does not make financial sense for most. Which makes me wonder if there aren't derivative issues (since the root cause was not addressed), in the long-term of a non-serviceable bearing that may surface before the engine needs to be rebuilt.
