Here's a very recent pic of a RS4 (4.2L) opened up to check for carbon that has 39K miles for comparison -

Being stock for the majority of his miles make me wonder what a chipped engine will look like with the same amount of miles on it. I asked about how hard it was run because I'd think those of us who run their cars harder than most would see less carbon buildup over the same period of time.

I've seen all those pictures of the RS4's and my understanding is that Audi made some changes with the newere FSI engine where this wasn't a huge issue anymore? Please correct me if I am wrong.
