Any one interested in the oiling mods I did?
Yellow rose I respect you and your knowledge but you need to think about this post you wrote. The brake system in your car is a sealed system with no flow. Two opposing columns of oil if pressurized has to go to the only place where leakage is available, the bearings.
The only place where there would be little flow is in the galley itself, which ideal. Sanborn used front oiling successfully and so did a friend of Pittsburg racer who posted about this issue extensively.
Cannot remember his name. He claimed he could not keep the motor together until he front oiled, and directed most of the oil away from lifters and cam bearings. Always more than 1 way to skin a cat.
You can make a test fixture to see the issue. A clear piece of tubing...1/2 inch will do and I’d use 2 or 3 tubes tied into the main tube so it looks just like how the main bearing feeds go into the main oil gallery. You’d need to restrict the down tubes a bit...maybe .312 max but I use .287 but something in that size.
Two small pumps, each one plumbed to an end of the 1/2 inch tube with regulators on them and something the fluid can discharge into.
You could use water. That’s cheap, easy and safe. With two separate small tanks, you could use food cooling in one tank to make it easier to see which column is doing what.
Then just turn it on and watch what the fluid does. What happened when both columns have the same pressure (I forgot to mention you need pressure gauges on both sides to see what the pressures are) and what happens when one column has more pressure than the other.
You can have pressure and no flow (or close to zero flow) with any fluid system. I learned it trying to run 5/8 fuel lines from the pump to the regulators. The weight of the fuel in the bigger line would literally stall at the launch. But I still had pressure at the gauge. I ended up with 3 gauges in the system. It was hard to watch them all at the same time, but you could see the pressure never change. But it went lean at the hit.
With a 5/8 fuel line from the pump it took about 35 psi of line pressure to stop that. That’s when we developed the bypass system. When all the smart people looked at it, they laughed. I’m betting most of them now use a bypass system of some sort.
Also, I’m not sure I understand your brake system analogy. Where in the brake system to you have to columns of fluid coming at each other. I can’t picture that in head.
And I agree there is more than one way to skin a cat and they can all work. If you can get oil to the rods at 8500 without correcting the oil timing then that’s all that matters. As long as the carnage stops it doesn’t matter how you do it.
