What is causing the drainage on my maple tree?

It is not likely a contagion. I'm less concerned about the seepage and more concerned about the crack itself. This appears to be "included bark," which is highly susceptible to failure. You should have a certified arborist look at this tree.
Visit www.pnwisa.org for information on finding an arborist near you if you don't already have one in mind.
