electrolysis fags, look it up sometime >:3 (mostly only old timey hot rodders care about this shit though)

That -is- the difference, I think the sleeves are steel, and the heads are definitely aluminum. Dissimilar metals. It was a wet-liner engine.

An O-ring at the top of the sleeve; at least some. The thing is rubber, in a tough environment.

The jugs in this case don't have any contact with the studs, just the block and head, however your point could still be accurate.

I looked for some pics of an engine apart, can't find any.

does anyone actually use distilled water? also has anyone ever use engine ice on a car, lots of track bikes run it

Yep, only distilled water here unless I'm in a pinch. My coolant gets changed so frequently though that it gets back to distilled within a month or so.

I use only distilled water. At roughly 99¢ every other year, it's cheap insurance. Use it in the WI system, too.

Yeah, I know. That's one big thing that separates it from a conventional water-cooled engine.

I've seen some in the past, just never paid a lot of attention to the mating surfaces. Seems that despite the availability of decent-quality aftermarket aluminum cases, a lot of folks are still cutting 'em down and converting to air-cooled for use in T1s.

Actually, that last bit of trivia reminded me that of course the sleeves are wet- the outer cylinder housing is a cast-in feature of the case, and the "liners" themselves are basically just T1 jugs with the fins cut off. (Ok, it's an oversimplification, but you know what I mean.) I won't even bother trying to explain what I was picturing previously- in order for it to make sense you'd need a fifth of rum & a severe blow to the head.

interesting because i've worked in a new car dealer since i was 17(12 years) and i've never seen anyone use anything but tap water and i've never seen anything seriously bad like corroding, scaling.....

I understand, I work on 'dubs.



On distilled water, again, Vanagons damn near demanded it, and it did help. But to carry things further, I have been told that for that much more insurance, distilled and -deionized- water is helpful. Apparently the distillation process charges the water, increasing the potential for trouble.

Distilled here. City water ate my hot water heater. I'm not putting that shit in my car.

Joe, I really did laugh. They died of shame. So true...

Hadn't really looked into it previously.

According to that web site, EngineIce is just propylene glycol pre-mixed with water. So it's basically the same as the "Non-toxic" or "Safer Formula" antifreeze you see at the auto parts store (the one with a picture of an SUV up in the mountains, with an inset of a young boy & his dog), only much more expensive. So on the downside, you'll need to use much more of it if you intend to poison a cat.

On the further downside:On the further downside, propylene glycol has slightly poorer anti-freeze and anti-boil properties than ethylene glycol for a given concentration in water:

Lastly, although their thermal conductivity & heat transfer capacity (per unit flow rate) are very nearly identical, "In most heat transfer applications ethylene glycol-based fluids are your best choice because of their superior heat transfer efficiency. This efficiency is largely due to the lower viscosity of ethylene glycol solutions. Another benefit of this viscosity advantage is lower power consumption for re-circulation pumps and a lower minimum operating temperature. " Source: Ethylene vs. Propylene Glycol

Me thinks I shall stick with Agent Orange.

then i guess it's all hype, except that it's not as slippery or hard to clean off a track. thus not worth it for car unless required

It's not all hype. At over $40 a gallon, EngineIce will add lightness to your wallet, and this is likely to improve laptimes somewhat.

Never grounded. EngineIce -- a sucker and his money.
