Quick Hose ID

Now I can focus on maintenance....

Can someone tell me what these two hoses are? Leaking pretty badly. Tried searching already (one hose appears to be the vanos oil line).

ID the two hoses farthest to the right thats seeping oil badly. Thanks.

Unrelated side story: Well after over a year of various fixes it seems like my p0171 and other lean codes boiled down to CCV. It gave out one day and lots of white smoked billowed from my tailpipe which freaked me out. Used the info of this site and figured out the CCV needed to go. Been driving over 2 months w/out a check engine light which is a record for me (had this car over 3 years) Thanks!!

Looks like power steering hoses. Where do they connect?

If your car is an automatic, those two lines may be to/from the trans from/to a heat exchanger. How do you know the leaks are in those lines? Could be dripping down on them from something higher up, like a leaky power steering reservoir hose.

The un-oily line running horizontal to the left is a high-pressure power steering line, probably not your problem here (but fairly expensive).

Well after further inspection, the power steering res. is caked w/ a black substance and the hose looks dirty too. Can't really tell if its the hose seeping or is it loose. So are one of those hoses in the pic a PS hose? Also, are these hoses prone to seeping or is more likely something leaking from higher in the engine? Thanks..
