have 50# oil pressure, but no oil is reaching the rocker arms on my Farmall H engine. Any one have any idea what I can do to fix this? I have checked for leaks and clogs. Don"t have either.
Thanks,
Bruce

Was it just rebuilt with new cam bearings? maybe the holes aren't lined up. Also check the bolt in the center of the rocker arm stand , it should have a hole for oil to get through. Maybe it was replaced with a solid bolt.

If you have some sludge it can clog up the ports. make sure they're clear and it should be good

If the passages seem clear, and the bolt is hollow,
It may be as noted below a cam bearing out of alignment with the oil hole. To check, remove the rocker assembly, and use a brass rod, or copper wire to feel in the hole all the way to the bottom.
The wire should be touching the cam journal through a hole in the bearing shell.
If it is, turning the engine very slowly by hand (incrementally) will allow the wire to go deeper when the oil passage aligns. If it never aligns, the cam bearing is probably the issue. Do not rotate the engine with the rod stuck into the cam journal, it will cut off a chunk that cannot be removed without surgery... Jim

we used to bypass that problem by using a hollow stud that held the valve cover on and had a hole drilled through at the point centered in the tube that the rockers move are mounted on. using a tee at the oilfilter pressure guage,,a copper tubing was then run from the tee to the hollow stud and thus the oil was fed into the tube to oil the rockers.
