Are your tailpipes sooty...
Mine are and I will posts pics when I get it back from the Indi who diagnosed scored cylinder liners #5 and #6. I have seen the boroscope pics and can confirmed scored. Sooty pipes can be an indicator of internal problems. Just wondering...

The Cayenne has a high incidence of this:
I wouldn't be shocked if our cars are at that level or higher. There are probably cars that have been running with some level of scoring for years. I have come to accept that sooner or later, all (or practically all) of the original 3.6 engines will develop scoring. If I found out I had scoring, my plan would be to run it until it wasn't making good power anymore.
I am sure that someone will come along and tell me how this will result in further engine damage, impure thoughts and my dog to run away.
I live in a fairly small and cold location. Upon learning about these failures I decided to dig deeper and asked for a list of all vehicles in my area starting with the VIN numbers "WP1AB...".
There were 60 vehicles registered. I got names of 44 owners from the DMV. Then I managed to find 33 in the phonebook/Facebook. Out of those 33 vehicles, 6 had new engines. That's almost 1 in 5. Some owners didn't have information about why the engines had been replaced but those who did blamed scored cylinders.
Two more haven't been diagnosed but are misfiring, one of those on the 8th cylinder. That would bring the total to 25% but as I said, it hasn't been confirmed. Out of the original 60 vehicles there have been 6 "decommissioned". I suspect scored cylinders to be hiding there as well. One of the owners notified me of another vehicle that had a European VIN number and therefore not on my list. That would bring the verified total to 7 out of 34.
I'm no car expert but a failure rate of 20-25% is a bit extreme to me.

In addition to the sooty pipes, which came first, followed by an increasing amount of oil consumption and the addition of the light ticking that turned into a fairly disturbing tapping when hot. Finally the CEL for #6 cylinder misfire and subsequent finding of an oil fouled spark plug. I decided to have mine checked out and now will get it fixed. I know there are other folks who have similar issues that keep adding oil and keep driving. Great for them. I hope it works out for them. Each to their own decision. I will post a pic of the issue in my engine on the #6 cylinder.
