    Hey guy . Back again. 2003 freightliner century isx450 Cummins I have replaced rod and main bearings. Oil pump, oil pressure sensor and oil pressure sensor wires. I will get a low oil pressure sensor warning maybe once or twice a week then it stops. Again I'm new to trucking and still learning and I have replaced everything I've been told to replace that the problem could be coming from. Can anyone help

    I would want a manual gauge on the mirror showing what the pressure really is. Also would want to know if the engine has the correct amount of oil in it. Is the oil to the full mark. Is the dipstick correct. Oil capasity can be looked up by engine number.

    Like BoxCarKidd said. Get a test gauge on it. I'd hate to hear it was just a damaged wire and you threw thousands into it.
