Hey guys, I think I know the answer but you guys know far more than I. My newly rebuilt 383 with about 150 miles on it started leaking engine oil today after a short drive. The oil is leaking from the transmission inspection cover (4 speed car) if I start it up it leaks a drop every two seconds, Turing off the car it eventually stops. After I removed the cover I found oil in it and you can see where oil has flung around inside the bell housing. I can see the end of the crank flange and it looks dry but behind the flywheel and clutch it's all over. I inspected the engine and no oil is leaking from anywhere else. Rear main seal right? Ugh... pic below of inside the cover.
