1986 Nissan 200SX Repair Question
1986 Nissan 200SX Oil Pressure Guage
1986 Nissan 200SX 4 cyl Two Wheel Drive Automatic 247000 miles
The guage does not seem to be working properly. The engine seems runs fine, I don't feel any difference, but the guage goes from one extreme to the other showing I have no pressure, to going to the high end, then to the middle. It's not consnstant.
What are the telling signs if I am having problems?
Unusual noises such as knocking, burning smells from engine compartment and poor engine performance are all signs of low or no oil pressure.
I would suspect a faulty oil pressure sending unit. This is the device that sends signals to the computer telling the gauge what to show.
