Inspecting my engine (head, block) internal anodes (3 of them) and one was fully crusted up. I know this is normal and it's part salt and calcium build up. However, when cleaning the build up, chunks fell inside which was impossible to avoid. Where did the chunks fall to? Should i be concerned? After i was done with the inspection and cleaning. , i flushed the motor from a large tub. Disclaimer: not my photo but gives idea what I was doing .
