If your talking about the high pressure bypass spring in the pump, that is not a serviceable part. You need to replace the oil pump.

Nissan has fitted the spring to give the correct oil pressure to the crank and cam bearings, you can damage the white metal crank shaft bearings by increasing the oil pressure , fit the standard spring.

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.

More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.
