Your low oil pressure IS a problem but your looking in the wrong area. The
thrust washers have nothing to do with maintaining oil pressure. You could
take them out all together and your oil pressure would not change one bit
(your engine would be trash in short order but that's another saga) They
are simply lubed by the oil squishing out from the clearence between the
bearing and the crank journal. Your oil pressure is detirmined by the
volume of the pump, the oil pressure bypass spring, viscosity of the fluid,
and the running clearances of the engine a change in any one of these can
cause a difference in pressure.
