Engine Oil Priming?

I'm priming my motor for it first run and am having a heck of a time getting oil to the rockers. I'm using the GM priming tool with a 3/8' drill on the end and have rotated it while priming. I've ran it for a quite awhile and can't get any oil to the rockers (drill is starting to smoke!!). The gauge is going up about halfway so it's buiding PSI. I've read this can happen sometimes and once it runs it should be fine BUT?????

Thanx:)

If yur really worried install the dist and pull the plugs. Pull the ECM fuses so it won't flood, crank with the starter and watch your rockers. Bet you get oil now...

I also have a question about this actually, but mine is more for the turbo, i was kinda worried about making sure that the turbo gets oil and such. So just priming the engine like i would do normally will take care of anything over on that end as well?

I did this recently on mine, so it's fresh in my mind.

I used a MSD prime shaft, has the bushing to seal up the area where the dissy flanges are.

Anyway, it took a long time to get oil to the #2 rockers. Odd-side bank was pumping like crazy, as was the turbo supply line.

I take an old distrubutor and remove the gear and the rotor,put it in and hit it with a 1/2" drill.Also works good for positioning the oil pump when installing the dist.

I also have the tool. You must seal the block passage just above the gear with either a tool, a modified dist, or my system with removing the plugs which uses your dist. Other wise you're just pumping oil back to the pan. No pre-lube.

As to the rockers. I believe (someone can shoot this down if I'm wrong) that if a lifter is up on a lobe and is collapsed because it doesn't have any oil yet no oil will flow through it to that rocker. That's why I like my system of removing the plugs and using the starter, naturally. It takes care of that issue.

Never dry turn over a new motor to prime it!!! Have someone help you and turn the motor over in 1/4 turn breaks

Dry? No assembly lube? All I know is that I've used my system with no ill effects on more than a few motors over the years. Including a couple of big, but older diesels that had compression releases.
