Brent, I think you got the right idea; put fresh
oil into the pan, use a drill to pump maybe 1 to 1 1/2 qts into a measured container...then after pushing the old
oil out into the pan, button up the hose, continue spinning the pump with the drill 'til you have pressure, top off the pan to "full", put the distributor in, fire up and retime...once every 3000 miles, no big deal...?
