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

Ok, **** it. Forget about all that you explain how the crossover does anything and don’t try to bullshit me that it slows the oil down because it damn sure doesn’t.

If the pressure is the same the oil velocity will be the same.

Next thing you’ll want me to think is an high volume pump will suck the pan dry. That’s as true as the crossover does anything.
Did you used to post on this forum under a different name. I seem to recall a similar member arguing the same way you are.
