rust in water

[Cornishman]

Rust is not caused by water, it is caused by oxygen and warmth. Any part of the iron internals will rust if it is exposed to air. Iron and steel submerged underwater will oxidise but more slowly than those exposed to the atmosphere. It is quite likely that rust has formed where there has been an air space in the engine. Antifreeze and other inhibitors prevent the oxidisation caused by water.
For my information: What is soluble oil? It's not something I've heard of before reading this thread.

Corn, I think I can help you. Have you ever heard of H2O? It’s the chemical formula for water. Have any idea what the O stands for? Think maybe the O stands for oxygen? I do.

Have any idea what the word you used, “oxidize,” means? It means combine with oxygen. You said, “Iron and steel submerged underwater will oxidise but more slowly than those exposed to the atmosphere” Since oxidize mean combine with oxygen, where did the oxygen come from in the water?? Think maybe there’s oxygen in that water???

So, by your own admission you think any part of the iron internals will rust if it is exposed to air but not water? Not sure if the people in Arizona or the Sahara Desert would agree with you. There’s plenty of air but what’s missing there, one might wonder?? Well there ain’t no water .. or very little of it; bone dry as they say!

Here’s how it works:

Specifically, when WATER comes in contact with iron, a galvanic cell is created kind of like a little battery. When H2O .. also known as WATER!! .. comes into contact with iron, the WATER will dissociate (break into its individual elements, hydrogen and oxygen) and then you have free O2 .. oxygen.. running around, which will bond with the iron to create FeO2, also known as iron oxide, commonly called RUST … which is what you see when the radiator cap is removed on a Model A run on straight WATER.

For your homework tonight, look up the word, “soluble.” Then consider the notion that oil and water do not mix. Next, ponder the meaning of soluble and you will instantly understand what soluble oil is.

Thank you for the unnecessary science lesson. Please read my post again and calm down. Thank you.

Easy to detect , look down the hole and see white, it is soluble oil.

I have not used it for years but I wonder if it would not put the greasy stinky scum on your windscreen of your model A as does coolant in an unpressurised system .

Isn't the white an oil/water emulsion?
