  1. I recently rebuilt a D310 and installed a new oil pump.  I’m running 15w40 oil.  On startup my oil pressure spikes to about 90psi and after it warms up it drops to 50.  If I really work her hard it’ll drop down to 30 at idle.

    Outside temperature is 80 degrees.

    is this normal?  I’m using a $80 auto meter mechanical gauge.  I haven’t checked any other gauges.


    The oil pressure gauge and light take about 3 seconds after startup to begin reading pressure.
