Rocker arm inconsistent oil flow

[Rounded_nut]

So I just did the first overhead that I know for sure was done, appx 100k on reman cm2350. The clearance is listed below. After doing all the valves I fired up the engine sans valve cover, and that's when I saw number 5 intake rocker not flowing oil like the others (#6 seemed light). Exhaust rockers just fine. I shut down and barred the engine into position to triple check the clearance, all just fine and set at 0.35 & 0.68 mm int/exh. Thoughts? I'll attach a picture.
