Why are crank seals a one time use only item?
If the ribbed portion of the seal is not ripped or torn, etc then why do these seals need to be replaced with each removal of the timing cover from the front of the engine?
I understand it's good preventative maintenance to just put a new seal in but I was just curious as to the real reasoning.
FWIW: I've reused mine with no leaks in the past.
If they aren't warped looking, or damaged, just reuse them

Thanks for the info.
