2018 Sierra 1500 Exhaust Manifold Leak

[FishNowWorkLater]

I have a leak on the drivers side, easily can see the black soot and will be fixed under warranty (Emissions Warranty).  When looking at the exhaust manifold is it normal to see a crack around the holes for the bolts?  It appears to me that the manifold is cracked near the bolt holes, maybe that's the way they are built I don't know.

 

Was looking for confirmation on that before I bring it to the dealership.

 

Thanks
