First, a little background:
My car has a little oil leak near the crank pulley, so I beleive its the crank seal, but really have no clue...This is a CRX with a B16A first gen boosted, stock internals, 12 psi tuned. may be burning some coolant at high rpms @12psi....but anyways...

So, today, I was making adjustments to my BOV. I brought it up to like 4-6 psi and let off each time. Now one time when I did it, I let off at like 2 psi or less and I heard something directly under the console kida make a backfire sound (muffled so it wasnt quite like backfire). after that odd little sound, I loosened the BOV a little thinking that maybe it was extreme compressor surge...(throwing out theories). Went again and there was no strange sounds, and teh BOV sounded just right, finally.

Well, as I was leaving the neighborhood, I see this black bolt looking thing laying on teh ground near where I heard that strange sound. So, I go back to it and pick it up. It's oily as ****. I have no idea what the hell it is or if it is even from my car.

Here are some pics of this bolt I found...

For some reason the nut on the otehr side likes to back off those bolts. Its happened to me once or twice. Not a big deal though
