I would pop off the section where the air box is and check to see if there is build up and discoloration there on the radiator. Whatever it is it looks like the fan spattered it on the timing cover.
Is the car white? White grille that maybe someone ghetto sprayed while still on the car? Did someone try to recolor the radiator fan white with paint? lol I've seen crazier things, but those are just guesses
Other than that, does it come off with a towel or is it really stuck for good?
