By design some cam/lifter combo's make it very difficult, if not near impossible to get oil to all the rocker arms simply by running the drill and turning the engine a few times.

I've ran into this more in recent years as we are using more custom cam profiles with smaller base circles, custom flat solid set-ups, and retrofitting to hydraulic and solid roller stuff.

It's not really a big deal, as long as you make sure the oil band on the lifters is correctly located during engine assembly.

Many lifters are also metered, as I found out when using the Crower HIPPO lifters for the first time. We gave up trying to get oil to the rockers first time we used them, but they do a fine job in actual use of controlling oil to the top of the engine.

+1 on assembly lube, if you are going to wash it all into the pan with the drill anyhow.....Cliff

UPDATE:

Went down last night committed to running the drill for 10 minutes. After about 3, oil came out of 2 cylinders. Rotated the crank 90 degrees a few turns and several more minutes of turning, I had of out of each lifter.

Looks like i just needed a little more patience.

Thanks for all the help

My 470/409 took forever to get it to the top on every one and I even used an old distributor to seal the passges or Chevies won't get it to the top. I think it was like Cliff mentioned where the oil bands of the lifters were.

On my Pontiacs I usually do it with teh valley pan off to see if there are any leaks around the lifters. My old 72 HO block did for a flat tappet around where the holes were tapped for lifter restrictors. Had to go taller rollers on that block.
