Ok, but so what.  Are you saying that due to this pressure the pressure reading
by the oil pressure gauge is or is not an accurate measure of the pressure as 
the oil
enters the bearing?  If the rod journals have such high pressure how does the 
oil
pump make the oil flow TOWARD the journals?

I think that you mean that there are transiently high pressures...  I think 
that the oil flows
during the low pressure times.  Those transients are why we care so much about 
the
film properties of the oils, etc.
