I installed a new oil pump, new oil pressure sending unit, changed the oil and I still getting a very low oil pressure reading. What can be causing this? I am at my wits end. Can't seem to figure it out.

Bearings have excessive clearance. Will have to be replaced.

Mains and rods. Drop the oil pan and the are 5 mains and rods are the numbers of the cylinders. Very specific as far as clearance. If you have never done it, dont reccomend you do it as you can do more damage than good

No, I am here and you are there. I am going on info you have provided to me.

Why dont you get a shop to do a manual test of the pressure to verify that it is as low as you said.
