I recently rebuilt the motor in my b7100. The tractor over headed and crack the head. After replacing the head I have a big oil leak right above the oil pressure sensor. It is leaking between the block and head. I didn’t see anything about an o ring I that area. Does an o ring go in between the block and head? What could be causing oil leak the that location. It is not a small leak.

Ya back left side by the fuel tank has an oring between head/block. Blue” if the gasket hasn't been through a bunch of heat cycles, and does not tear at removal you can just add the oring.
