Looked around with a flashlight and found a nice coolant puddle under the PCV valve (which was replaced about 20K miles ago with OEM).

Yup, the coolant pool is definitely on top of the block. I'll confirm tomorrow with daylight once I snoop around some more. How serious of an issue is this to drive around with?
