Here are some pictures I took recently when I replaced the valve cover gaskets on my Honda 3.5L. I have had this since 8800 miles and have been doing OCIs of generally 8-10k miles with Pennzoil Platinum or Mobil 1. Filters have been either Supertech, Wix or Napa Gold.
The only build-up I could find was a tiny bit on a couple of bolt heads. A gentle swap with a q-tip moved most of it. I have been told to try to swab the bottom of the oil pan and see what's there. I will try to remember to get some extra-long q-tips before the next oil change.
Overall, it looks great to me.
