Oil leak

I just did the valve cover gasket not long ago and I looked and there’s a decent amount of oil buildup where it’s circled. I’m just curious if anyone would know why, if maybe would the gasket not being seated properly would cause this or if maybe it’s not tightened enough? I put 80 ish inch pounds on the E11s for the valve cover so I’m not sure what’s causing this.
