And I don't have an issue with that because that is what it does. What I am 100% against is what the OP said in post 4, in that it slows down the oil. It does not and it can't.
If you are running hydraulic lifters and want more oil at the mains the crossover will do that and with pushrod oiling it works too (or both hydraulic lifters and PR oiling).
But this fallacy that it slows down oil and that's the secret sauce just is wrong.
