Reman Parts Include the following...
A RX7Store ad claims that the Mazda Reman engine includes...
Each engine receives careful inspection upon disassembly and all components cleaned and checked for wear or damage. All engine seals, bearings , gaskets and related springs and rubber "O" rings are replaced with new OEM parts along with new rotor housings.
I ws always under the impression that the housings and some springs were only replaced "if needed." Can anyone confirm that the Reman engine is as stated.
If so, I see no reason the reman engine should not have the same lifespan as the original - the only parts not replaced are the rotors, stationary gears, and the eccentric shaft. Am I missing anything?

I think they are playing with words. If you look at the first sentence you'll notice that ALL COMPONENTS are checked for wear and damage. If they are to be replaced with new regardless, why bother checking them?
By the way the statement is made, reuse of acceptable parts is implied, and they would not get into any legal debates if someone was to complain.

The thing I hate about "out-of-spec" is that to me this means that if a part is supposed to be no smaller than 5mm and and no bigger than 8mm, and is measured at 5.5 mm, then I am getting a part that is performing within spec, but will have a very short lifespan.
In an engine, this may translate to an effective lifespan of 13 months, vs 5 years. Feels like a ripoff to me. Wear parts should all be replaced.

If they are honest is they do not replace all parts then they should say "All parts not within specification..."
I guess I need to take it to my lawyer for a professional opinion.

That's not exactly true. If everything was working properly in theory, there would be no wear. The specs are used for eliminating problems stemming from the manufacturing process. All parts when manufactured are not exactly the same no matter how precise the manufacturing process so there are specs to govern what is accepted.
If everything was properly lubricated, there should be no metal to metal contact at all to cause wear. All surfaces should be riding on oil molecules. But there are many real life variables that can be tossed into this otherwise perfectly balanced mechanical system. Overheating causes components to expand at different rates and warp, momentary lack of lubrication, incorrect A/F ratio, the list goes on. These "abnormalities" are what causes the part to be out of spec.
So an engine with reused parts (that are within spec) properly cared for will last just as long as an engine with new parts. (The FD back in 93 had brand new engines, look at how long they lasted)

However, I'm not quite sure we can say how long the 93 engines lasted because I don't think we really know what killed them. Did they really have short "natural" lifespans or were a significant number of them victims of dealercide (not knowing what they were doing) or ownercide - (abused, modded improperly).
