So my inspection plug was very badly sized so I first cut a slit in it with an angle grinding and hammered at with a screw driver for a hour with no luck. Pieces of the plug were cracking and breaking off. So I broke out the drill and started drilling some holes thinking it would relieve some of the pressure, it didn't work. I stared hammering the holes with the screw driver again until enough of the plug had broken off to actually unscrew the plug. This is where I notice I messed up...bad. What are my options? I'm thinking if I just put a new plug in with RTV in the massive pits and it might be okay. or do I need a new side case?
