I have to agree with you about the tracks, but when we were putting together the 29 sedan delivery I looked into Evans and told the guy that owned the car to buy it, he was the one that sent me some neg reviews on it, so then I looked up Evans and started reading about it and reading every thing that came up and there was a lot of people that had leaking problems, mostly old cars old style engines so he oped out of buying it. With out pressure in the system your not concerned about cavitation?
