oil leak?

Has anyone ever heard of a Blue Line or Little Giant external pump leaking oil into the pump head and into the tank?

We've got a Little Giant on a closed loop and the Blue Line on the tank return. All we have is tap water while working out the last kinks in plumbing. We've observed hazy water for a couple of days and now where water was turbulent in the sump, it is almost like we have a skimmate line on the wall. It dries crusty but I can't tell if it's biological or not. Thoughts?
