Post #129, as suggested above, is wrong for this application. There WILL NOT be any oil leak as is indicated. Please remember, the engine being discussed is a 59 block. The pushrod bushing COMPLETELY seals at both ends. Rotating the cam bearing is not necessary if the bushing is in place. For electric pumps I always insert a small, tapered, aluminum plug in the bushing which can later be removed if a standard fuelpump is desired. The plug can help in cases where the stock fuelpump stand and breather are used, without all the original baffles, as oil can be cast upward from the camshaft lobe where the fuelpump rod is designed to operate. If the stock baffels and tube are missing the breather can receive an oil fog.

The rear cam bearing receives oil from the rear gear housing which quickly fills with oil from shaft clearance at the upper oilpump bushing and from the clearance at the upper oilpump housing machined O.D. section.
