IT also could have been a situation where the anti-freeze used was
a contributor to the 'crud build up'.

Modern anti-freeze formulations are Different then what was once was.
I have had first hand experience with modern formulations creating
its own crud, lots of it!

It's mostly designed to be used in sealed systems with NO air gap
in the top tank. When the changes began to be prevalent several of
the name brand manufacturers were sued by a govt. agency for false
advertizing their product as 'Universal' one jug (ours) works for
everything.
Anywho, it does seem to develop particulate matter that settles out
much more then our old cooling system design likes.
I believe the older formulation of Ethylene glycol anti-freeze can
still be found.
