Pan bolts tend to loosen over time. Tighten all M8 pan bolts to 23ft-lbs. The remaining 3 M6 bolts in the very front are hard to get to without removing the K-members. Proper torque for them is 89 in-lbs.

Try tightening all of the M8 pan bolts first to see if that helps. If you still see any leaks at the front of the pan, then pursue the M6 bolt tightening process.

If leaks persist, it will require a new pan gasket.
