Speaking of loose bearings, I wonder if a wide pressure range like this could 
be a indication of a worn or lost thrust washer? I've seen wide oil pressure 
ranges certainly on very worn engines, but, maybe a drifting crankshaft could 
also cause such readings and, conversely, such a wide range could be an 
indicator of a thrust washer problem?

Any thoughts on that?,

 volume, this then reduces cooling to the rest of the
 bearings, etc. >>
