Well,,,,John,,, i have had something like this on my mind for a long time,,,, I rebuild old Buick engines and cars since I retired, and actually before that,,,, and I like to prime up the oil pump , set timing, ect before I go to the trouble of setting the thing back in the car... that way if there is a problem it is a lot easier to deal with and when you set the engine back into the car it goes in you know that it is good to go.... I am copying all this info for future use.... thanks a bunch ,, you have saved me a lot of work and mistakes, I do know.......
