Default Rail Pressure Relief

Just curious, but will the engine still run with it leaking slightly or even fully blown?

bosch says that once they pop they will never totally seal again. i'm not really sure what pressure they pop off at but i know i ran mine above the limit and then i could hold only like 20k at wot no matter what i did. sometimes it would be hard to start and would kinda studder at idle. well mine is fixed i plugged the dang thing.

yeah that's the main reason that my banjo bolt got tapped and i installed a set screw in the banjo bolt. not leaking now. oh yeah had the set screw and tap in the garage so it didn't cost me a dime!
