Sorry to the OP, but I would have to agree. I did mine last year and I did not have any crud like that under the valve cover. My motor was on Mobil1 with oil changes every 5-6k
I used Permatex orange all around the perimeter of the valve cover (vs. only at the "half moons" as the Bentley recommends) but I noticed that it seems to be slight wet around the rear of the engine recently. Might have to redo it if it gets worse.
BTW, the "exterior" of your engine does look clean (at least compared to mine)
