Help 351C 4V Drivers side head not getting oil when priming motor

[Cleveland Crush]

We pulled the motor and took the plugs out on rear of block right side filled with oil left side dry. Looks like a total tear down unless we can figure this out.

Sure sounds like the #5 bearing at this point.

I'm assuming you checked the right side plug depth? Run a wire down the passage from the plug down to the main bearing to check for obstruction. Otherwise you could pull the pan and check # 5 main bearing orientation. I'm really curious about what the issue is.
