That sounds like a reasonable explanation. I can see how they would get
work hardened when they are restretched and we did reuse
good used ones on this rebuild because it was a few years ago and there
were no new tubes available at the time. Now I can get them again fairly
cheaply so I would use new no matter what. I did just this on a cylinder
head replacement job we just did. I hate when reusing old parts comes back
to bite you in the butt. Usually when you are doing it to save the
customer some money too.
