I can’t seem to find what this plate is called can anyone help me it’s leaking from there but the plate is missing on mine

Looks like the plate attached to the IMA motor. Maybe the rear main seal on the engine is leaking?

The part number is 1A226-PHM-300 and Honda still sells them if you are looking for one.

Tekuno is correct, you shouldn't be leaking oil there with or without that plate.
