Pinion Gear Chipped - is it ok to run?

It' broke off on a high spot of the ring gear, the more important spot is the low spot, I had a gear like that and ran it a year ago, and burnouts later still going. just clean out any metal and run it, 8 3/4 are tuff assssss shittt. But the seller should know better, and should of let you know about that chip.
