Au Contraire, I drive Olds oil pumps with an old oil pump drive shaft with
a hex socket welded on the end. One end goes down the distributor bore, the
other into my cordless drill. All Olds engine distributors used in our
motorhomes turn counter clockwise when viewed from the top of the engine.
The oil pumps are self contained, and do quite well when turned with a
cordless drill with enough beans to turn them. If you are anal, rotate the
engine to uncover the oil passages along the crankshaft a few times while
you are prelubeing. If you are really, really anal, pull the rocker arm
covers and check that you do not have any stuck valves. They don't play
well with reciprocating pistons.
