loose rod, spun bearing, check the oil for metal, coolant mixture, or just check if it has oil in it?

Not sure if I have anything valid to add to this, but the Steamy water you noticed around the exhaust port is what mine was doing when I broke a spring and dropped a valve in #8. I think I posted a vid of it on here back in November. Link to that post is below.
