Priming motor oil - again

When I finished rebuilding my engine about 2 years ago, I primed the motor oil by pulling distributor and using the priming tool to spin the pump. Now I have engine back in truck and just about ready to start it.

Is it necessary to prime it again?

I would, lots of settling could have occurred in two years...

Try to use the kind of primer that fits/fills where the dist goes down by the gear or you're wasting your time.

2 years sitting there with oil in it.. I'd drain the old oil and put new oil in before anything. Just to make sure it didn't get gummy. Hate to have to drop the pan after its back in the truck..

Was trying to avoid taking out the distributor again since it is a lot more difficult with the engine in the truck. We have the correct tool for the job.

Any other options? Maybe using a electric pump pushing oil through oil pressure sensor port and out of the drain in the pan?

The oil in it is not synthetic. Not gummy. Will be changed before start up.

As an aside, this weekend we took apart my brothers original 1969 dodge hp 440 cu in engine to inspect it and refurbish it for installation into his recently restored Coronet R/T. Engine was rebuilt, driven for about 500 miles, pulled from car and has been sitting in his garage for 20 years. No joke, but engine parts still well oiled including the bearings and it probably could have been started (after a oil change) without a major issue. Heck the small amount of anti freeze that was in it did not look half bad... Obviously we are replacing all gaskets and o-rings. Also replacing bearings even though "new" and valve springs (appear to be the original ones), freeze plugs and cam since one in it is aggressive (car was converted to 4 spd but is now back to original auto) and he is going for stock.

Yup, just pull the plugs and spin it with the starter until you have oil pressure. Reinstall plugs and fire away... Disconnect fuel injs or pump so you're not pumping fuel in it.
