why do we have water seals?
Hey guys. I was just thinking, why do we have water seals? Seems like something else to go bad, you know? Just wanted to know what they're there for, might be very obvious but just let me know. Thanks.

how would they blow if we didnt have them? or more to the point, how would you keep coolant out of the combustion chamber without them? nsu rotor housings are "closed" so they dont have water seals, but i'm sure it adds other problems and cost

In order to keep the engine from overheating and destroying itself, we have to put coolant flow around the housings.
In order to keep fluids from flowing between two metal surfaces that can't be made perfect, we need to sue gaskets.
That's why they're there. The coolant HAS to be there, and Metal-to-Metal contact is never perfect enough to make a seal, so water-o-rings must be used. The o-rings keep the coolant from outside of the inside of the engine, and from outside of the engine assembly.

No different than having a head gasket

Dealers like charging you for them
For the amount of power we have, we need water cooling assist. Too bad that the seals aren't robust enough. Too bad that the Mazda rotary is an iron/aluminum sandwich engine and that the metals expand/contract at different rates. So, once you overheat, say 'bye bye' to the seals.
Too bad that they didn't overheat when new and all failures are because of owner negligence.
