RARELY the oil pump is at fault. How much hot idle oil pressure? How much at cruise RPM? Mechanical or electric oil pressure guage? Are you sure it is good?

Are the front oil galley plugs sealing? Are the main/rod bearing clearances correct? New cam bearings? Are they installed correctly? If any of the groove behind the cam bearing is uncovered.....pressure will bleed by.
