Looking under the car: Find the leak, name the cover

[ac4000]

Took a quick look under the car today while changing out the coolant level sensor and RH headlight washer and I found two things I'd like to correct.

First, the power steering system is leaking somewhere, but the level is fine (or slightly high, reading at the top dipstick mark). It's not leaking at the reservoir. What would be the most efficient way to start tracking it down?

Second, this rubber cap, just forward of the transmission oil pan, appears to be ripped. Anyone know what it's called so I can find it on RealOEM and order a replacement?

1. Power steering leaks are common, hard to tell from the picture.

2. It is just called a cap, here the part number.

I'd be happy to have those leaks, the bottom of my engine is drenched.

Thanks, man. Since the PS leak isn't currently causing any problems, I'm going to move it down on the list until I get the cooling system issues sorted. I'll take more pictures if I can at that point.
