This is interesting

Well, maybe...
I have my motor all put back together except for carb and dizzy. I figured that it was a good time to pre-oil the motor since the valve covers are not nailed down yet. Being that I am doing this in the cold in an unheated barn, I was worried that moisture would be an issue the longer the motor was open. Anyway, back to the chase...I started running the drill and almost immediately I was getting oil at the rockers. Great ! This is working out well ! Unfortunately there was none on the drivers side (left) bank. What the...?? So, I pulled the rocker shaft to see if I was getting oil at the 2 bolts. Nada, now I am a bit stumped. I cleaned out the block holes and the head passages when heads were off, but somehow they must be plugged. Or could it be that my cordless drill just doesn't have the oomph it needs to bring it up ? The next couple of days will be warm (almost 40) , so it will be easier to work for long periods.
Thanks

Rockers oil on the cam at different positions from the #4 cam bearing when rotating. Turn the motor over some and it will oil the opp side rockers. The motor oils one side of the rockers and then as the cam spins, the oiling hole in it lines up with the opp side port to oil the other side of the rockers. I did the same thing on my first engine. I kept priming and getting no oil to the upper end. Spin it over as your priming and you will see oil come to the opp side no problem. See below.

who put the cam barring in ? hope the hole lines is lined up.

I had oil to both banks before I redid the topside of motor. I think 91R/T has the answer I am looking for. I was just too cold and tired Sunday to pursue the issue any more, you know that pre-hypothermic cognitive function decrease. That's my story and I am sticking to it !

I have a set of old off brand chrome valve covers with the tops cut off so I can oil the engine and spin it over until both sides are completely oiled well. This way I can watch it oil without it drooling all over the floor and making a mess of my new engines. I know what you mean by cold....living in the NYS winter climate sucks

Don't hold me to it but I'm pretty sure at top dead center (compression stroke) the cam's oiling will be lined up to oil the right head rocker assembly. Then turning the crank clockwise, in quarter increments, I'm thinking at 3/4 the way around, the cam oiling will be lined up for the left head rocker assembly. Wish I had taken the effort to document this. Many say to just keep turning the crank to get oil to both sides but there are two exact places where you can get oil while priming the pump to verify good oiling after assembly.

I said the same thing. I usually turn it over slow and end up getting oil pretty quick.

Skytrooper, good to see a Mopar enthusiast from CDGA. Spent 50plus yrs. on Mopar's and Mopar notables in town. Good Luck on your project

There is still a pretty good presence of Mopar enthusiasts in the area !
