Any thoughts on that?

There were problems with the cam chain tensioners that plagued engines for years (finally fixed), issues with the 2.7 L case, I"m sure there are gobs more issues. That said, the bottom end of the air-cooled sixes were capable of going as much as 300K before rebuilding.

However, I don't think that any of the air-cooled six variants had the failure rate of the early 996 motors, but Porsche isn't talking so facts and figures are hard to come by.

Other significant Porsche engine problems: early 944 cam belts (snap!), 928 Nikasil blocks, etc.
