Oil leak yoke 727

[tomsa]

Hi.
I have a new rebuilt 727 BB that started to leak from the yoke.
No leaks overnight but after 3 days I have a small lake under the car.
It leaks from the center of the yoke so its not the seal.
Why start leaking after 3 days and should it be som sort of hole in the yoke?

Of course it is possible but not probable especially since the fluid is really on the outside of the yoke. Some fluid could get inside the yoke I suppose but the chances are the fluid is coming through/under the seal and then following the yoke before dripping off.
