White Substance in Cooling System
I've got a new build.... 360, Edelbrock heads, aluminum radiator, aluminum water pump etc. It's got aluminum parts. The motor has only about 100 miles on it, and I recently disassembled it to balance the rotating assembly which I should have done before putting it together in the first place, but we won't get into that.
I noticed small deposits of white chalky stuff in the water jackets on the heads and various other areas where the coolant flows. In the past, I lost a set of aluminum heads on another motor due to electrolysis. After that I learned that if you have aluminum parts on an engine you should put a sacrificial anode in the coolant. So, that's what I've done with this engine. I have two anodes in this engine.
I don't know if the deposits in this engine are due to electrolysis or maybe something else. I'd like input if anyone has anything to say on this subject. Attached is an example of the deposit in the water pump, and the type of antifreeze I'm using.
