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

Reverse feed the number one main? Go look at a schematic and tell me how that works. The number one main is fed from the front hole of the drivers side gallery.

Just retarded nonsense. No one EVER blocks oil to the number one main BEFORE the main bearing. No one. And if they did, WTF did they gain?

If you have the book, then perhaps you need to read the entire explanation, and not just look at the picture. The proper implementation of the crossover is a two part mod. The passenger galley is plugged in front of the #1 feed hole. The pressurized oil that was sent to the drivers side now feeds number one main. Simple
