How did you come up with code 17 on a OBD2 vehicle ? Should be a P0117 .

yes it is as long as it does not over heat. the thermostat is set to open at 195 or a bit above. Normal running range is 180 to 220 degrees operating temperature on your car

How low does the pressure get? It only takes 4 psi to keep an engine lubricated. The pressure will drop off as the engine get to operating temperature. This is normal. As long as the pressure climbs instantly when you accelerate you're ok.

First NORTHSTAR ( 1992 ) engines were quite troublesome, from faulty starters ( in the middle of the engine ) to loss of oil pressure.
