Priming engine oil

Unless you have reason to believe there is a rocker arm issue, and it can be challenging to get the crank in just the right place twice to get oil to the rockers.
We're it me, I'd have a friend watch the pressure gauge or light, failing that set a mirror on the seat in a manner you can see either, then use drill till you have steady pressure on the Guage, or the light goes out .
Button it up and start it .
Good luck
