So, nova do you think that 1 CNC machine was out of tolerance for a few hours,days weeks, or months. Could all of the machines been programed incorrectly? Could it have been a CAD engineering or design flaw (I'm a big advocate that true engineers have been replaced by graphic designer fools, that just know how to use a CAD)? Is it possible that Porsche is using different CNC makes or models to make the same part? Finally, if it was just a QC issue, then who was the jackass that was hiding in the bathroom, while both of my engines were being messed up.

Any discussion about what truly happened in terms of the machining error is speculation: the number of incorrectly programmed CNC machines, how long the production error occurred, and whether it was a programing error or basic engineering flaw. I doubt it was a design flaw, because this happened after many other 997/987s crankcases were already produced correctly. Instead, I think that one day, someone incorrectly programmed a CNC cutting machine, and the recesses were cut 1 mm too deeply.
It is apparent to me that even Porsche doesn't know how many VINs were actually affected, and hence the list of possible affected VINs, some of which turned out to be unaffected.

They probably used an outside source for them and got a bad batch. I posted this before but when there for a factory tour I saw "Merceded Benz" stamped on the tranny's. Maybe they made them and F'd them up.....it's hard to say.

well, my (dads) 997S was listed as a VIN potentially affected, but the dealer did a check of the engine earlier today, and said that it was fine. Its back home now - I sure hope they are right
