Did you consider that you could have had a post shutdown boil from heat soak ? The water could have been boiled out. It boils in the head & sort of does a reverse burp, a bit like gastric reflux.

Yes, I'd thought about that. So, what, just replace the expansion tank cap?
I'm also thinking it could be the overflow system.
At this point my goal is to rule out the engine....then I can relax a bit.
