Please help!!! major oil leak!!!

[Az Yota]

I just purchased a 94 4runner with 175,000 miles, 27,000 on rebuilt motor. And i know that the rear main leaks, that doesn't bother me, but there's two lines that run underneath my fan, i was hoping someone could tell me what these are? please help, thank you

do they run to the oil cooler?

The lines in pic #1 look like power steering lines or trans fluid lined. im leaning toward power steering tho.

So the line in pic #1 does go to the power steering pump, and it's showing a major leak, but the fluid level hasn't changed in a couple days. And i'm leaking about a three inch puddle of oil over night, but have no idea where it's coming from because sometimes it will leak a ton, and other times it'll sit for hours and not leak at all, anyone have any ideas on what that could possible be. I know the rear main leaks, (new that when i bought the truck) but it wasn't this bad of a leak. any help is much appreciated
