Thanks. In fact I did refill the radiator recently and the last time it
overflowed, it was more like foam (like the end of overflowing which
might be wishful thinking). 

        But I am surprised that overfilling should lead to overflowing
since water does not expand that much. [On the other hand, I haven't
yet built a capture bottle as described last Spring by a number of
people and all my other more mundane cars have them.] But interestingly,
the fluid in the radiator hasn't dropped much below the neck and no core
is showing.  BTW, the radiator was recored last year!

And I will change the radiator cap anyway
since it is muchos years old and I really did not believe the cracked
head theory because I've had that condition on other cars and in no way
does this mess resemble that mess.
