The oil pressure is too much. It could cause the oil filter to leak or if you have an add on screw on filter adapter it can cause the filter to burst.

If in fact it is not a gauge problem and actual 75# pressure it is most probably because the pressure relief valve in the oil pump is stuck. Over time the plunger that is spring loaded will develope a wear pattern on it and become uneven instead of being completely round and smooth and get stuck in the bottom of it's bore and never move against the spring so the pressure goes way up more than it should. A new oil pump is the way to go to fix it. On the NAA it is pretty simple to replace the oil pump. Juat pull the oil pan and then the pump and the oil lines that go to it. Be sure that the seal on the pressure line is replaced where it enters the block. Also be sure to replace the oil pump drive shaft.
