No Oiling Right Bank of Rockers
After 2 years of not running the 312, I finally got it all set up and it fired right off. Problem is the right bank of rockers isn't getting oiled. I changed the oil and filter, and pre-oiled with a drill before starting it up (I only pulled the left side cover to check ). Oil pressure is excellent at the mechanical gauge.
Wanted to find out where to start looking for the clog. Old oil was diesel black, but no sludge or chunks in it. Engine runs great, aside from the clicking dry rockers.

its been about 30 + years since i had a 312, great engines, but as i remember they offered a kit that you plumbed into the oil sender and ran a little copper tube over head to oil the rockers, the oil problem was caused by the cam bearings turning just enough that the oil wasnt able to feed the rockers. guess the easy way would be to pull the cam and check. i do remember now that some one actually used a long drill to go down though passage from the head and drill though the cam bearings. guess that would be a way of checking. pull the cam use a wire from above and see if it goes though the cam bearing. again they are great engines.

Hmm, just pulled the rocker assembly and there's clean oil under the mounts. Going to run some compressed air into the oil passage through the head, in case it is a clog, and clean out the rocker shaft. Hoping that's the issue. Might as well do the simple stuff first, before having to tear further into it...

First remove the shaft and make sure it is assembled correctly. You should see a hole in the shaft that corresponds with the hole in the head. Just flip it over and look. If you do not see that hole, it is assembled incorrectly. Once that is confirmed, turn the pump by hand or with a drill and see if oil is flowing from the head.

same as charliemccraney, and me, i had a friend that had to drilled down though because the holes wernt lined up form head to cam bearings. if you cant see you should be able to slide a wire though and look up the cam bearing journals. is it ok to drill though, i dont know, might shorten the life of the engine down the road or might not hurt anything. but yeah first check it out, its cheaper than buying a new engine. and when its all said and done youll be happy and know its right.

The overflow tube also locates the shaft within the stands. If the shaft was installed incorrectly, then that tube has also probably been shortened. Make sure it goes not only through the stand but also through the hole in the shaft. If it does not, get a replacement.
The shaft probably will not move once bolted down, but the tube does ensure that it gets installed correctly and does not change position during installation because if I'm not mistaken, the tube will fit only that hole, so if the tube is in, you know it is right. I've never checked for myself, though.

Fired the ol' girl up before going to work today. Ran great, and didn't have all the rocker noise it had before. Pulled the valve cover (gotta love the two bolt covers) and everything was nice and oiled. Now just time to get some new overflow tubes.
Thanks everyone for your input! I'll get some stuff posted when I start getting the Y-Block installed into the 64.
