Where would oil be leaking from if it's the valve cover gasket? on 1999 Suzuki Grand Vitara

How do I know if the valve cover gasket is leaking? Where is it exactly?

Asked by for the 1999 Suzuki Grand Vitara
Valve cover gaskets are below the tinny covers over the heads. Never worked on a V-6 Vitara, but here is a pick of a Chevy 350. where it says Chevrolet with the chevy sign, those are the valve covers.Usually only a few bolts to pull off, gaskets are cheap. ANyone with a better pick?
