Re: Pressurized center main bearing?
Just one comment. Joe K in post #14 made a comment that the pressure was not enough to force hydrodynamic separation (of the journal to the bearing). The hydrodynamic separation is caused by the rotation of the journal in the bearing. There is a wedge of oil formed that is dragged along with the journal and this actually does the separation. The pressure that is formed is many times more than the oil pressure, even in a modern engine.
