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

I still don't understand what hydraulic principle is at work to cause this.

Then it doesn’t happen, even though it does. I don’t know how else to explain it.

The same thing happens to the fuel system except we are dealing G forces. You can have full pressure on the gauge and ZERO flow.

If the crossover was the **** everyone would do it on everything that is laid out like a Chrysler. But they don’t.

If it worked you’d see lines running everywhere. You don’t.

You can have pressure and zero flow. So running two columns of oil together from opposite direction will cause at some point full pressure and zero flow.

I’m going to have to get a small Chevy block and crank here and make a video so I’m not typing the same **** over and over.

Looking at those two systems you’ll find that one will oil to 10k on stock parts and the other won’t run reliably to 8k without a ton of work, regardless of all the bullshitters claiming they were doing it back in the day.

Then look at both of them and you’ll see why that is. How much and when the oil gets to where it needs to be is critical. Chrysler missed on both and a crossover won’t fix that, which was the point of my first post.

It doesn’t fix anything. It’s used to put oil to the drivers side lifters when the OE feed is blocked.

Why do you think a BBM will kick the 5-6 rods out? Do you think the cross over would fix that? Of course it won’t. It can’t because even if you did a crossover you aren’t fixing the issue and that’s feeding both rocker shafts off the same main bearing PLUS the oil timing to the rods is off. RPM makes it worse.

So whether or not you can grasp that you can have pressure and no flow, or whether you grasp that you can over pump the engine and band aid it, you have to address the root cause of the failures. And you can’t show me a single example of the crossover slowing oil down to make a turn.

It’s a constant flow system and once you have pressure the flow is controlled by the leaks. Again, the crossover tube does not and can not slow the oil down an IF it did how would that solve the issue of taking oil from the mains to feed the rockers?

Answer: it can’t.
