Over the years, I have kept a watch on the oiling of my Rocker Assemblies on my 1956 Victoria. Although the rockers were not getting a lot of oil, there was a trickle of oil out the overflow tubes and there was oil pooled in the bottom of the heads - so I thought this was ok. Recently it became difficult to maintain valve adjustment so I removed the Rocker Assemblies and disassembled them. I found about half the rockers severely scored, as well as the shafts where the rockers run. Since these are the hard to find high ratio rockers (and since I have a lathe with a grinder attachment and a milling machine) I plan to re-bush the rockers and grind the shafts rather than search for high $$ parts.

The first order of business (of course) will be to ensure that the refurbished rocker assemblies will be getting adequate oil - and this is what has me stumped right now. I removed the spark plugs so the engine will crank fast and after about 1 minute of cranking there was no oil at all coming out of either oil port in the heads (the low oil pressure red light does go off shortly after cranking begins). Next, I took an oil gallery spiral wound brush and turned it counterclockwise with a drill motor (to bring sludge, etc out the top of the port). I did get thick sludge, but nothing solid. Still no oil out the ports while fast cranking. The following is what really has me baffled. I applied compressed air to the top of the Driver's side oil port and I could hear air flowing out the upper oil breather and the Passenger's side rocker assembly oil port. Next, I applied 90 psi air to the Passenger's side oil port. There was no air flow at all. Then I rotated the engine by hand in small (about 3 Deg crankshaft increments) and applied air again to the Passenger's side oil port after each increment. I did this for over two complete revolutions at the crank. There was never any air flow. What I don't understand is how there could be air flow coming out the Passenger's side oil port while applying air to the Driver's side oil port. Does the same cam bearing supply oil to both banks, or is there a separate cam bearing for each bank? Any ideas, comments, etc would be greatly appreciated.
