I need some help from someone that knows. Does anyone one know exactly what fails in the oil pump? I just installed a new pump and I am running between 20 to 1 and 13 to 1. This is the same as the old pump and is why I changed it. The cable adjustment is correct and the oil pump arm moves through its sweep and returns smoothly. By the way its a 98 SX700. I posted here because I know there are more engine guys on this forum.
The oil injection tip was not hardened and it fails making the tip to big. But from what I remember that was only on the 600 twins that it was a problem.
