Predictably, it's leaking. Would I be insane to remove the studs and try flattening the surface with a large sanding float that fits across the transfer case? Machining would be the gold standard but that's a huge amount of work for a leak.
I'm thinking of trying it just with sealing compound, does anyone have recommendations re. anaerobic, hard-drying vs. flexible, etc? I'd also appreciate any tips for not getting the compound contaminated with oil, it seems like it drips forever from the low side. Is it worth roughing up the mating surfaces slightly?
