  • Speedo / Tach / Gauges: Oil pressure gauge: 56 Golden Hawk

    The oil pressure gauge on my 56 Golden Hawk with the 352 Packard engine always shows 40lbs, cold or hot. It is at zero with engine off and jumps to 40lbs on start up and stays there only fluctuating very slightly on acceleration or at idle. Any thoughts? thank you, Nick

    First, verify actual pressure with a test gauge at the engine. If that gives the same readings, it might be due to a very weak spring in the oil pressure relief valve.

      The 1965 Hawk has a Stewart Warner direct reading oil pressure gauge which are very accurate, It unlikely that the gauge is bad so Dwain G's recommendation is a good one to verify whether or not your oil pressure gauge is accurate or not. There have been issues with the oil pumps in the Packard V8 engines so hopefully Jack Vines will comment as he has experience with those engines. Bud

        With the motor running, use your fingertips to peck on the face of the gauge, most likely the needle will jump a bit higher, especially when cold. Once warmed up, 40 PSI, at 2000 RPM and up, may be about all there is, depending on condition of the motor, oil pump, and weight of oil. As long as your lifters don't clatter, no reason for concern. The lifters are the canary in the mine, for the 56J's oiling system.
