Maybe it's your crank seal located just before your harmonic balancer.

Running down the back of the engine? Can't be crank seal then. Maybe rocker cover gasket?

rear main seal is at the rear of the crank, it requires gearbox or engine removal to replace

Rear main seal is a cheap job Degrease ur engine bay and then just wait till it starts leaking

degreasing the engine bay wont fix an oil leak lol. if the oil is leaking on to the outside of the gearbox, the rear main seal is unlikely. The only two possible causes for oil to leak down the back of the engine and on to the gearbox would be rocker cover gasket or head gasket.
