Low oil pressure?

The books I have say the pressure would be low and erratic not necessarily none.
I know that my x block and the r race blocks have a feature cast in to reverse feed the main oil galley. The idea there was opposing pressures cancel each other to stop velocity in the galley to better feed the main bearings. That could partially be what happens without the plug. As I have said, without the plug there is not always a clearly defined flow path which for lack of a better word could cause erratic flow.


You need to stop the flow from the other direction if you bring the flow in from the front.

And BTW, that won't fix one single oiling issue. I've posted so much on here about that topic that I ain't doing it again. The oiling issue isn't about where the oil comes from, oil velocity, crossover tubes or any of that other bullshit.

A 1960's SBC will oil itself to 10,000 RPM's plus and not have bearing issues. If you want the truth, study a SBC and then figure out how to copy that.

Anything else s either bullshit or lies.
