Pinkish/white stuff under the hood?

[wooverstone8]

Now I'm getting an odd noise somewhere in the engine compartment and now there is more pink stuff splattered all over the underside (not just a thin pink line like last time) of the hood and in some parts of the engine. When I took to the dealership a week ago they said it’s normal and they wiped off the pink strike, but I honestly think there is something wrong now. I decided to schedule an appointment with a different dealership in another town.
