With all this talk about oil pressure I was wondering if someone could
inform me of just what oil pressure is and how it is generated.  I know
there is an oil pump and I think the spacing between the bearings and
the crank/rods is involved but after that I'm guessing.

Do the bearings restrict the flow of oil thus creating pressure?  Is the
oil pressure measured in the crankcase or ?  You get the idea I hope.
I'm just looking for a sort of oil pressure circuit diagram if you will
or a Oil Pressure 101 class.

Thanks as always.  If it wasn't for this list, I couldn't afford to keep
my vans going...
