Oil Leak - From Where?

More than likely that’s just a valve cover gasket leak. Maybe an intake manifold gasket leak depending on where it’s at.

If there’s so much oil in the coolant that the temp sender is leaking oil, you have a serious problem.

Whoa, um yea.:D
OP, keep in mind that the cooling fan blows oil backwards toward the firewall.
I'm betting on the front of the intake or valve cover also.
Oil stick is a possibility as well if you have some blow by that a PCV isn't keeping up with.
