oil leak from where?

[cj847]

My LS swap is leaking oil and I have slowly been fixing everything that is leaking. I am down to oil dripping off the torque converter cover. I thought rear main, however, after removing the TC cover the torque converter and starter teeth are bone dry. I have since added a dab of ultra black on the outside of the oil pan on both sides (ie where the dab goes at the junction of oil pan and rear cover) but I don't think it was leaking there.
It appears something above is leaking. So I removed the intake to investigate the CPS and the oil pressure port. There is seepage there but not a smoking gun. Is there anything else it could be?
