I'm replacing mine with copper.
However, I have read of some saying that copper may crack from vibration.
Has anyone heard of or had an issue with the copper tubing?
Copper tubing does become harder over time . If not properly looped for stress relief the vibration will crack it premature . You are correct that copper can fail , this is why the auto industries does not use it . I even had to replace the copper tubing on my air compressor a couple times . Not good in a vibration environment .

Re: Making A New Oil Pressure Line.

My 66 has a steel line which I assume is original. There is no loop in it either.

Is steel w/o a loop correct? I need to look in the AIM to see if there is good illustration on the instalation.
