Hi, i'm curently haveing an oil pressure problem with my grand am. I've replaced the sender for the temp gauge, still no luck. I have replaced the oil pump (had to change the oil pan to match the pump) and yet i still have no oil pressure.
When the car is cold, i have over 40 lbs on my gauge. After you drive it and it warms up it will eventually drop to 0 and the check guage light will flash to draw your attention to the oil pressure.
The car doesn't knock like theres no oil, so i'm stumped as to why it does this. Everything else appears to be ok, I know its leaking some oil on the valve steam seals cus sometimes when you start it up it will burn a little bit of oil.
