For the oil pressure stuff on the ground? Ask for either checklist or just shut it down, it is not critical on the ground anyway.
That is exactly what I did in a 727 one day when this happened, however, it was the FE that saw the oil pressure's sudden drop and as I had my hand on the fuel lever, I just shut it down and then called for the checklist.
It was an oil line that maintenance had not tightened, made a terrible mess.
