When I was rotating the pump I had oil returns from the lower block
connector that normally fed the distributor. But when I let the drill speed
up the oil would immediately start rising out of the distributor base hole
in block. Can a guy just cover the hole w/ a cloth while turning the pump?
Would this oil normally just fall back in to the oil pan? Otherwise the oil
will all end up on the floor. Larry.
