hard or soft copper line for a valley oil gallery bypass line?

I was going to post a drawing like that. It shows how ridiculous his understanding of hydraulics is. According to him, the oil will just sit in the galley going nowhere with 80psi pressure on both ends and not flow to the 4 leaks in the tube. He also denies that if you take away the front feed that there is no possibility of some of the oil running past those 4 leaks because there are 10 leaks at the end of the galley(lifters on the drivers side)
that are gushing oil and that number one main is the one that’s feeding 9 of those leaks.


The very FIRST modification MUST be stopping oil leaks at the lifters. Or at least stopping 95% of the leaking. If you don't do that there is nothing else you do will help, with the exception of getting the suction side of the pump the very best you can.
