Have to take the opposite view on that Carl. If we're at that
point...that is, a bent push rod, no way would I re-use a
bent push rod unless I was out on the road and needed to make
it home. Rolling them on a "surface plate" or known flat
surface is a good time tested way to "find" a bent rod, but
once it's bent, for the cost of a new push rod ($5-$6), why
take a chance on it failing again.
If the tube is bent, the metal has been stressed beyond its
yield point stretching the materials grain structure on the
high side. When you bend it back it will pull the grain apart
on the low side and the column now has a weak point all the
way round where it's gonna fail again.
