oh I know, thats what I am saying, every situation is isolated, and there is nothing I really should do, or would want to do to test this, like not changing the belt to see if its true lol. I change the belt on time no matter what, even when I have owned non-interference toyota engines just for the sake of changing it. The only reason I wanted to know is because it would be kind of cool to know that nothing would happen should the belt ever break at low rpms.....
