If the seals were soft either by design for failure in the manufacturing
process, then the wear and lost of material in a critical area of the seal
combined with side forces due to the worn slot were probably not  a
combination  due for long life.

 
Has anyone heard what sort of reputation the Hurley's have in RX-7's?  I'm sure we're stressing them more overall than what the average car does, but you would still think people would report early failures if the seals were too soft.  Some of the RX-7's are putting out big HP numbers, but of course you can't do that for long on the street without ending up dead or in jail.  In fact, I sold my FD to avoid the inevitable outcome :-)
 
Add my congrats to your engine restoration.  I wish you had better weather to install it, but we take what we can get.  I didn't fly at all this weekend, partly because of the strong (cross) winds, and partly because the Navy was stinking up "my" airspace trying to catch up on training lost due to the hail damaged aircraft. 
 
Good luck,
Rusty
