Is something leaking?

[Twistoffate0817]

I opened my hood today, because this morning, when I started the car, it almost sounded like it was dry. I do not know how to explain it. It was idling loud, and was just making a horrible noise. I turned it off, then started it again, and it made the same noise. Once I got to my destination, I turned it off, then re-started it, and it was fine. So the horrible noise came from a cold start. I then looked at the inside of the hood and saw white/pink splats. These were not there a few weeks ago, due to I checked my Transmission fluid, and did not notice the splats. Anyone have any ideas what this is?

Also, I saw there was some white on my belt (pic included). Is this something to be concerned about?
