Could be an intake valley seal, or a distributor o ring, most of those leaks are seepage leaks as there is not any pressure behind them, if it is leaking a lot of oil with the engine running then it is a pressure leak and needs repaired quickly. You didn't state an engine so this is kinda general

It's a v6 2.3
