Would you have to have the motor dowled, and would you have clearance issues with them. (IF THERE WAS SUCH A THING)

We use something similar in jet engines turbine bearing sections they are ONE time use metal crush gaskets. They take literaly 30-45 min to torque down correctly not a big deal BUT I believe they would be a horrible application for this as the rotor housings can flex ever so slightly on higher hp/rpm applications. This alone will cause this type of hard seal to fail in short order i do believe. They are made of stainless steel as well fyi, look just like an o-ring just metal.

This is what pineappleracing offers.

Detailed Description
This is our exclusive Heavy Duty Water Seal kit for the 3-rotor 20B. We tested these seals for over 7 years in numerous street and track cars before offering them to our customers. They have proven to be a significant upgrade over the stock water seals. We use them in all our 5-year warranty motors. Also, these seals are re-usable if you need to reopen the motor to freshen it, as long as the mileage is not too high or the engine too overheated. In other words, if you make a mistake and blow up your engine or perhaps improperly clearance the seals or whatever, these seals can be removed, allowed to "rest" for about 30 minutes and be reused when you put the engine back together. Stock water seals must be disposed of when freshening an engine, even with just a couple heat cycles. Kit includes the water jacket o-rings, front cover o-ring (and backup washer, if needed), dowel o-rings, rear stationary gear o-ring and oil pedistal o-rings.


I really just wanted to know if there where such a thing as copper seals, and if they where any kind of an upgrade.

I think you're right about ruining a housing Tyler.
I'm willing to bet the reason noone has really dealt with the solid off the self seals is that they're not continuous. There's going to be a back where one end begins/ends. To me that's a big risk for a leak. The right way to do it would be to make a casting based on a housing, and form a piece. But that's me. Frankly I don't think any thing more than stock is really needed in this case, unless there's extreme forces, or someone want to experiment, or someone is really cheap

You could by-pass discontinuous seals by just cutting them out of a solid sheet, then sanding and grinding to specific tolerance. You'd still have to finish the seal even if casting it. But I don't think you could cast a seal--too small, and the metal too viscus.

Give it some time--I'm sure it will get cleaned up mod style.

Why? It's not directly exposed to flame, nor much of anything. If it works it works.
