We can repair Cayenne blocks
We have a process now where we know exactly how to repair the Cayenne engine affected with piston and cylinder scuffing.
We will bore your block from between 0.010" to 0.020" to remove the gouges, plate it with NiCom (Nikasil) back to near-original dimensions, have custom Arias forged pistons made to our specs, and supply them to you with new piston rings designed for Nikasil. Our pistons are specially manufactured to fit on the stock rods. All you need is an engine gasket set, a set of bearings, and put it together! In addition to a SUV-saving repair, these forged pistons are much stronger than the stock cast pistons, and the Nikasil-over-Alusil composite is tough-as-nails for your block! More information here: 928 Motorsports - Engine Block Repair Kit for the Porsche® Cayenne

what the . .
How does that carnage happen? With piston and cylinder scuffing fully around the circumference, it looks like someone filled the case with 40-wt sand.

How does this happen, low oil pressure or excessive heat?

It was first thought to be sulpher in the fuel. Then it was thought to be found in only Cayennes with cast, not forged pistons. Some think it has to do where the car is kept (cold vs hot)
The official line now from Porsche technical Bulletin is it was caused by a boring/honing process that left the cylinders prone to distortion. They have corrected the problem as of about 2012... That said - not all 2002-2010 Cayennes have this problem. But it is common enough that we get a lot of calls for it.
