Not so. I've taken many apart, which after removing the olive, show

The indentation of the pipe makes me to wonder if replacing old olives
when re-using compression joints might not always be a good thing. I'm
wondering what happens if the new olive doesn't line up exactly with the
groove created by the old one, this could lead to a much shorter area of
tight contact with the pipe and perhaps a less reliable seal.

I should point out that not all show obvious signs of indents - just some.

But if you're simply re-making a compression fitting, there's no need to
change the olive.
