Fluctuating oil gauge

Hi,

It sounds like the oil pressure switch may be going bad. We have two choices. First, replace it and see what happens, or get a mechanical oil gauge at a parts store and see if it has the same results. Most parts stores will lend you one. Basically, you remove the electric oil pressure switch and install the mechanical. There is an oil pressure relief valve, but that usually isn't the case. However, take a look through this link. It explains how fix a high pressure issue.

I can help you locate the oil pressure switch and explain what to do, but I need to know if this is a full size van and I need the correct engine size.

Let me know.

Thank you Joe. It has a 350 engine. The oil pressure sending unit?

Hello, I'm Danny.

As Joe stated you can possibly rent a mechanical gauge at your local auto parts stores and test the oil PSI by putting in place of the oil sending unit. It is located at the top rear of the engine block near the ignition distributor. I've attached pictures below of what it looks like and its location.Hope this helps and thanks again for using 2CarPros.
