Question about Chevrolet Nova
First, let's determine that the oil pressure sending unit is not bad. Can you hook a mechanical gauge up to the engine? If the mech gauge reads the same as your other gauge, you def have an issue. Either the oil pump has excessive clearance internally, a VERY weak (or missing) oil pump relief spring, or you have a severe oil pressure loss inside the oil gallaries in the engine. Some engines have restrictors in the oil passages to control the pressure. Doubt that this is the case here, though.
My best guess (and, this is a guess) is maybe the oil pickup tube is loose, or the oil pump is loose. If so, the pickup may be pulling air, instead of oil, and lowering the pressure. Get this fixed ASAP, low oil pressure will damage you new motor.
Hope this gives you a little light on the subject.
