Jon, There's no sulfur in Ethylene glycol.
(C2H2 2(OH)) 2 carbon atoms, 2 hydrogen atoms on the carbon atoms and 2 hydroxyl groups. It can't be from the antifreeze breaking down. It must be from something else.
The only source of sulfur would be from sulfur containing fuel. Again, the coolant system has been compromised in some manner and is being contaminated. Cavitation in diesels is a mechanical erosion. This occurs when the shockwaves transmit through the cylinder walls and form tiny bubbles in the coolant and then collapse. Cavitation occurs in many processes where power is applied. Cavitation is a major erosion problem on commercial boats that see a lot of hour of service. The area of low pressure on the propeller will erode away requiring replacement. This will also, be seen in high speed mixers and pumps in manufacturing equipment. But it is mechanical, not chemical. Cavitation is a very real problem with diesels, and should be dealt with accordingly to minimize the conditions that cause it. Yes, it can flake off the scale adhering to the walls, but it's shockwave erosion (cavitation) that does the damage. The "sour" condition (acidity)is most likely caused by outside conditions. KRM
