Anyone had this happen? I just filled the differential on the 80 Camaro, and it is leaking through the casting, just behind the pinion. I have attached a photo. Is there something one can do to seal this?
Appreciate any feedback.

porosity or a crack?

Seems like a strange pattern on the casting? It does appear to be in the indentation on the casting, could be crack? Car had a V6 so cannot believe it is do to high torque? Seems more likely a casting defect?

First I have ever seen a leak like that in a casting.

Looks like a casting defect. Drain enough lube to get the leak to stop. Clean multiple times with brake cleaner until there is NO lube residue. I use Black RTV silicone to stop leaks on my Pete with very good success. Work the silicone into the crack as much as possible and let dry for a few days before re-filling. There isn't any pressure there and I believe it will stop the leak.

I was able to get this leak taken care of. I cleaned up the casting, and applied some JB Weld to seal up the leak. Has not leaked now for about 4 days
Thank you all for your suggestions.

JB is good stuff too, I suggested the silicone as an easier to apply repair. I actually repaired a cracked block in a boat I owned for 17 years with JB and since the coolant has no pressure like a car, it never leaked a drop in all those years...
