Oil pressure problem
My 96 deville is giving my the damn flashing light and stop engine warning every so often sometimes days and week apart I have had the oil pump and oil pressure senor change. On the day when warning shows up rpm are around 700 when idle. I need help!!!!!!!!!! I hope I don't need Bearings Might junk if I do Because I Have 200000 miles on motor
I usually troubleshoot oil pressure problems by temporarily installing a known good gauge in parallel with an idiot light sensor and finding out what the problem really is. Then you can tell if it is a worn out motor, bad relief valve, or just a sender problem.
Try one of the heavy duty 15W40 oils such as Delvac or Delo or Rotella. The extra viscosity may help prevent the oil pressure warning light from coming on.
Was the replacement oil pressure switch an OEM part or a generic part from the autoparts store?? If it was a generic part you might try the OEM part as the set point for the oil pressure warning is specific to the Northstar.
