I have my '59 235 out and am in process of sorting out some things and detailing the engine. I have the oil pump removed and am questioning the need to take it apart and go through it. Oil pressure is good, and the screen is quite clean. Seems I'll need to use an impact driver to get the screws out, and am concerned about getting a replacement gasket.

Is it an absolute necessity to go through it? Some opinion based on experience out there would be welcome. Thanks!
