Is the head off? If so replace with the normal tubes. For the tow piece
tubes the o-rings always move. If there weren't leaking before they should
be OK going back together unless you removed them and stretched them out.

Subject: Re-use collapsible pushrod tubes? New o-rings available?

I was just cleaning up my pushrod tubes, three of which are collapsible, and
was wondering I should re-use the collapsible ones. The o-rings look to be
in good shape, and I don't think the collapsible ones were on long before I
pulled the motor. If I replace the o-rings what material should they be made
of? Nitrile?

Thanks, Tom
