77 rocker oiling

[TheJDWorkmen]

Hello, I am working on rebuilding 77. Today I cleaned and installed the rockers. Before I hooked up the oil line to the them I took an oil can and pumped the rockers full to make sure oil would come out of each rocker as need be. But, oil does not come out of the end rockers or one of the middle rockers. Now the one end rocker will drip oil out of the valve side but not the tappet side. Is this something I should worry about.

Shortly after Oliver introduced the 77 diesel engine the design of the rocker arm shaft and rocker arms was changed. This style was then used on both gas & diesel engines. How old is your 77? Does the oil feed line enter the rocker arm shaft in the center or toward the back? What happens if you apply 2 or3 psi to the fitting on the shaft you have and then move each rocker arm?
