        I would think that SOME pressure would be necessary.  What I'm 
currently wondering is whether the bearings could be completely 
starved for oil due to a blockage, and it not show up accurately on 
the gauge.
        I'm a little fuzzy on the path the oil takes through the engine, 
pump and cooler.  If the relief valve was opening early and staying 
open, could the crank bearings lose their oil supply while the gauge 
still shows pressure?
