1966 Rover 2000TC - Oil Leak at Front of Engine

My early Rover P6 2000TC predates the addition of PCV. It’s leaking oil at the front of the engine, and I’m wondering if anyone can point me in the right direction to where the oil might be leaking out.
It’s a bit tough to track down because the fan seems to blow everything around quite a bit, but it sure would be nice to get this sealed up a bit better.
