If you have a leak between the curved front of the pan and the front plate of the motor, you can seal that externally with RTV. You just have to get it really clean, run a bead and work it in place with your finger. It is not under pressure and is above the sitting oil level in the pan.
Yeah, I really need to drop the pan though. This thing sat up almost 40 years. I need to clean the sludge and dirt daubers and god knows what else outta there.
