hey guys have a quick question?
i have an 05 coupe with 109xxx KM.
recenty i have started seeing that when i start up my car the oil pressure light flickers for a slight second and then turns off. it doesnt do it all the time. and the light has never came on and stayed on or flickerd while driving.

so i ended up getting a new sending unit from infiniti, and i also picked up a oil pressure gauge. i installed it all up using a tee off the oem hole in the block.

so when i leave he car sitting for around 14 or more hours (cold start) the pressure gauge reads around 90psi, after the car is fully warmed up and at idle the gauge reads around 17-20. and at around 2000rpm the guage reads around 46 psi.

i have found the values that are in the FSM in regards to ideal oil pressure values and it seems like the car and gauge read all the write values.

i have checked to see if the tee connection is dripping any oil and it has not left any spots.

so im not to sure whats happening with the oil light flicker?? any ideas?
i have check my oil level just in case and its slightly below H on the dip by well within the proper range.

any ideas???

thanks in advance

In your post you don't say that the light is still flickering after the sending unit replacement. Is it?

Did someone suggest this as the cause? Not sure if there is a way to test the sending unit or not.

Just trying to clarify a few things....

Wonder if there is a way to test oil pump? A lot of FI peeps use a Rev-Up oil pump as an upgrade to the DE pump.

i havent gone checking the pressure manually, but now the oil pressure is way lower than what i had before and the oil light is always on now, i just did an oil change with the swap of oil sending unit, anyone got any ideas on this matter?
