Frustrating Oil Leak

[Rocketsled]

Try installing a PCV Valve. Relieving the pressure inside the engine might effect the oil leak. My 59 A/B leaks not! I installed a full-circle lip-seal on the front of the crank and a PVC tappled into the underside of the intake manifold. The PCV was from an early Mustang 6 cylinder and has pipe treads on one end, so it screws right into place. No hoses!
I use fluid grease, NLGI #000 with MoS2 (Moly) in the gearbox and steering gearbox, and they don't leak either.
