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

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

Right. I can do better than that with a set screw. The whole premise that the oil has too much velocity is the issue.

I have to lol that you think blocking the oil to the number one main and back feeding it by rerouting is comical at best.

Number one fix is sleeve the lifter bores and block the oil to the drivers side with a set screw under the number one main bearing. Does the same thing.

Or tube the passenger side and block the drivers side oil with a set screw under the number one main. Does the same thing.

Or tube both sides and block the oil off under the main cap. Does the same thing.

Or you can waste time and money with a crossover.
