Engine Oil Priming Question

I've heard of using the priming tool, though I've never used one, you could make one out of an old distributor if you have one from the old or new engine you're not using (remove the gear and use a drill on the shaft).

It may be a good idea with a motor that's sat a long while and that hasn't been coated in assembly lube. You could also squirt a little oil (even a blast of wd-40) into the spark plug holes to help it while cranking if it may have gotten corroded over the years.

In my experience, just removing the coil lead, and cranking for about 15 seconds 2 or 3 times (give the starter time to cool) will more than build up full pressure. Your oil pressure gauge should also show "normal" pressure while doing this (it's really just an on / off gauge in the dash). You could also verify by doing this before installing the upper intake and removing a valve cover to watch the oil getting to the rockers.
