Bad head gasket, cracked head?

or could be both.

glad you caught it. probably didn't do any other damage.but if the enging has
to be pulled for the upper-end repair. it doesn't take any extra time to pul
the pan and replace the rod & main bearings anyhow.

I'm hoping they can do it without pulling the engine. It's got 770 hours
on it and not due for this yet, I hope.
