I have 240K miles on my car and it looks somewhat like that under the oil cap. There's some crust on the springs but everything else looks cleaner (no black). I have been doing short oil change intervals (4000-5000 miles) using quality LL-01 synthetic oil and it hasn't cleaned up at all. It would be nice to see it sparkly clean but I think the only way to do that would be remove the valve cover and spend a lot of time soaking/wiping/polishing.
