I was installing my APR R1 DV today, and I noticed some oil deposit around the hose leading to another black plastic valve housing just beneath the diverter valve:




Any idea what this valve does and whether the oil is an indication of a catastrophic failure of a crucial component?

I took a photo into the airintake hose inlet that the diverter valve connects to, and noticed some splash marks, could it be the oil from the leaking valve? pic:



now i am all worried!!!!
