Does anyone know what's causing this?

Thank you both. I'll start by cleaning it up. I didn't notice the A/C lines, but I'll check them, maybe over the weekend.

Thanks!

While you have the engine in service mode, check the power steering fluid level. Chances are it's low as most people skip checking b/c it's such a pain in the a$$. Be sure to use the proper fluid (Pentosin CHF 11s), not some garden variety fluid.
