This sounds like most likely an oil pressure sending unit problem. These vans are somewhat known for this problem. The sending unit sits down near the oil filter and will cause the gauge to read intermittently when the sending unit is faulty or not connected properly. If the oil was recently changed you may want to verify that this was not affected in the process. If you’d like some help with this, consider YourMechanic, as a mobile technician can come to your home to diagnose the gauge and help you fix it accordingly.
