I found a similar build up in the engine I took out of the box, an engine father had apart about 7 or 8 years ago. The rear part of that was blocked.
Father had been using neat water latterly as oil was getting into the water. I changed head and fixed that and used glycol.
The build up had a blue tinge like yours, so its antifreeze based. I soon found a void behind it when poking about. So it was local to the ali (which was actually perforated in spots after a clean - despite not leaking in service)
Probably explained why the swine ran warm.
Is it from mixing antifreeze manufacturers products? or is it a reaction with the ali?
