Coolant

water soluble oil sounds impossible?

Not impossible at all.
There's quite a few oils with emulsifiers and water mixtures used in many advanced machinery applications. Such as some precision CNC or water jet style machines.

And there is also bio-based oils that are soluble (or at least miscible) too.
Then there's synthetic oils made just for mixing with water. Again, mainly in specialty cutting or lathe type operations.

not to hijack this, and don't wanna start a new thread. coolant filler neck has a nipple pointing toward the back, what goes there? I really need an answer, thank you.

[PearlWhiteR/T]

I believe the nipple your talking about... is supposed to have a hose connected to it that runs to the coolant overflow tank.

[a2j]

there are two of them. one facing forward, the other one - backward. I know about coolant overflow.

[DocWalt]

They're the turbo water lines.

Here's a coolant question I'd love to have an advanced tech answer. What is the water distribution proportion from the front 3 cylinders to the rear 3? Is it 50/50? Should it be 50/50 if the rear bank is storing more heat? Can the water be redistibuted in a way to flow a smaller portion thru the front water passages vs. the back to make better use of evenly cooling the block?

Same with the oiling system is it a 50/50 system from top end to bottom end or more like 25% to the heads and 50% to the bottom end and 25% for everything else?

Coolant chemistry is a lot more complicated than I first thought. Apparently the Japanese frown upon silicates in their coolant and the Americans and Europeans do not. In any case coolants (I should probably say "coolants" or antifreezes since water is the actual coolant, but you know what I mean) have evolved differently in Europe, Japan, and the US. I would be cautious about mixing chemistries. Being in Florida, I was under the mentality of run mostly distilled water with a little coolant and some water wetter to keep the corrosion down, but after reading more on the chemistry is behind these coolants, I will be running 30-40% antifreeze without water wetter. This is because I want the corrosion, boil, and cavitation protection of the coolant I don't want the water wetter messing with anything. I don't think 100% water with water wetter or engine ice is going to hurt anything if it's in there for a short period, but I personally wouldn't leave it in there for a year or two. Next time I change the coolant in the stealth, I'll probably use Zerex Asian Vehicle: Valvoline.com > Products > Zerex > Antifreeze Zerex > Zerex® Asian Vehicle Antifreeze / Coolant. Looks like good stuff. There's a lot more to this that can be found by searching "coolant chemistries" or something like that. It's pretty interesting.
