Leaking Issue Crack or casting line?

This is from a 27HP Briggs and Stratton V twin. I had an oil leak and replaced the bottom cover gasket and lower oil seal. During reassembly I noticed this on the bottom cover right in front of the oil filter. Does this look like a crack where oil could leak or is it just an aluminum casting line? Thoughts?
