George,
I agree with you on this point!
In fact many rebuilds are done with the types of
rotor housings you described, but the life is limited. Many of the local young
lads eagerly proclaim they can get a rebuild cheaply - little do they realize
they paying a lot for a set of new rubber seals.
This isn't the type of engine you want for Aviation
use.

My

My first teardown and rebuild 13b had rotor
housings with some of the steel plating missing along one edge. I took them
around to every "expert" that I could find, they all agreed that they were
fine to use. I then went ahead and assembled the motor, with new seals,
gaskets etc.
The motor ran great, like brand new I imagine.
But,
When it was time to install the motor into my airplane, I just didn't feel
good about those rotor housings, so I found another motor that I've been
flying since 1998. By peeking inside I knew that these housings were
pristine. I still have the first motor, but I doubt that I will ever use it
without another rebuild with new housings.
Bert Rutan said something to
the effect of "Do your very best, even that will only be just barely good
enough".
I know, that sitting on the end of the runway, I must feel
confident that everything is as good as I can get it, in order to enjoy my
flight. Others will differ perhaps.
