Yes a contradiction in his reply. If it is strictly based on hydraulics and the idea is that pressure goes everywhere, then how can an equal but opposite direction, stop the flow.
It doesn’t, but it sure cuts the speed or velocity down, leaving the oil nowhere to go, but to the main bearings. I have a friend that ran a small diameter line to the back of his big block for the same reason. Big blocks
oil from the front of the galley, but same principle.
