I cleaned up the undercarriage to try and figure out where this oil leak is coming from. It looks like the oil pan gasket is leaking. However, it doesn't make sense that this much oil is leaking from this spot. Does the oil in the oil pan sit higher than the line of the gasket, specifically here on the rear arch? I would think the standing oil level would always sit below the gasket so as to not worry about a small leak when the engine isn't running.
