Hot running Jubilliee/NAA valve adjustment?

How much oil should I see coming from the rockers/shaft with the engine running? I see a small hole in each rocker on the top/valve side, should these all have a seep to oil the valves? I only see oil from those on #1 cyl valves. Oil pressure is ~40 psi.

Engine idling and the valve cover off you should be flipping oil off of each rocker and getting your distributor and ignition side accessories covered in oil after a few minutes.

I thought as such. Looks like the rockers/rocker shaft needs to come apart and cleaned/inspected. Has not been run hardly at all since (minutes) R+R head was installed. Wanted to do hot lash with the hood/gas tank off first.

What sort of end plug does the shaft use? 2 shown in the IPL, no mention in the Ford shop manual. Are the rocker shaft supports located by pins like a Ferguson/Continental?

I didn't take the shaft assy apart when I did the head as it appeared in good condition.

It does take some time to get oil to all the places. The way it works is there is a passage in the camshaft which aligns with the feed tube every revolution. So it 'pulses' oil rather slowly up the tube to the rocker shaft. You should ascertain the feed tube has a seal and is inserted into the block above the cam gallery. Removing the side cover will allow you to inspect the situation. I am uncertain what the end plug of the rocker shaft situation is, I don't remember ever dealing with it on a Ford. I have had to fuss with Ferguson Continental engine rocker assemblies before where they use a cork to plug the ends of the shaft.

I'd recommend a manual if you don't have one. Dad had a Jubilee when I was young but that was before I was doing anything more than tune-ups on tractors. I've a lot of experience with the Red Tiger 172 engines which are quite similar to the 134 in a Jubilee, but the '53-'54 Jubilee/NAA engines were the first of the run and there are a few idiosyncrasies associated with them.
