Anyone have the experience of measuring their oil pump rotor clearances? My
manuals say wear between inner and outer rotor should not to be above .010.
Mine measures from .007 to .009 on four points if I measure with the rotors
in place but if I take rotors out of the case I get more like .020.
My low oil pressure I'm sure is due to worn bearings (down to copper) but am
thinking of replacing rotor innards on the pump while I have it out - don't
want to spend the $40 if it's not neccessary though - any thoughts out there?

pretty good oil pressure to the rockers)
