i am trying to prime the oil pump with a 3/8 drill using the oil priming tool and cant seem to get no oil to get to top of motor around heads and or timing gears..i got oil coming thru the oil filter.at first but not sure what to do from here..please help..thanks

terrible one

Turn the engine over a bit by hand and prime a little, then repeat the process a lot of times if you are by yourself. Really, I cheated and blipped the starter, primed, blipped the starter, primed. If you've got a helper, just have them steadily turn the engine over using a breaker bar on the damper bolt while you prime with the drill. That should get oil everywhere. You have the rotate the engine while priming so that all of the oil passages have a chance to line up and let oil up top.

Yep, need to turn engine over little by little till you line up the passeges for the top end.

I was thinking putting the drill in reverse....since a B/RB engine distributor runs counter clockwise??

Yep, run the drill counterclockwise to prime, and have someone turn the Engine over by hand slowly, so that the #4 Cam Journal feeds to the top end line up one at a time.
You'll hear a sploosh as one Heads Rocker Shafts fill up, then slowly keep turning, until the other side oils yer shoesies ! (assuming it's on a stand)

I just did the same thing on my 440 this weekend!

Use a drill, run it in reverse because the distributor/intermediate shaft spins counter-clockwise.  Oil to the top end gets there via the number four cam bearing, and holes in the bearing line up with a cast in passage in the block and through the heads.  The cam needs to be rotated to a certain spot, to allow oil to pass through that passage.

My engine is 'supposedly' rebuilt (it came with the roller car), so I'm really nervous about how well it will work out.  I damn near had a panic attack, when I couldn't get oil to the top end, I figured some arsehole installed the cam bearings wrong.  I rotated the motor by hand, via the crank bolt, about a half inch, ran the drill, rotated another half inch, ran the drill, and on and on.  I got oil to the passenger side head first, after a few tries.  I kept doing the same thing, until I got oil to the driver side head.  Needless to say, I was quite relieved.

It'll work!
