I won't EVER use the starter motor to build oil pressure, NEVER tsk
That is a old SB Chevy SOP, think about how many RPM the motor is spinning over on the starter and then how many when running work
Will the oil pump work better at 150 RPM or 600 RPM? work whistling
I also fill all my oil filters up completely (until they won't take any motor after soaking full many times scope up) with oil before mounting them on the motor, that way I don't have to worry about how long my motor will run with no oil pressure after changing the oil and filter work grin
