Ok guys, was on the way home with the wife, actually had a nice night out away from the kids Low on gas, fill up at a gas station, 93 octane, go about 10 miles and the CEL comes on. I think, bad tank of gas right away, although no rough idle, etc..car running ok still, not in limp mode, no blinking CEL, just stays on. I get it home and I find a nice hissing sound coming from the back of the engine. Below are the links to the pictures, it's a small house coming off the top of the engine block, with out my manual, THANKS Go Motors!! I don't know really what is goes to, my thought it is vacuum pressure inside the block, which explains the little bit of oil leaking out. Let me know, thanks guys!!

Looks like the black plastic check valve at the lower end may be bad.
