Bad oil pump or main bearing?

Hi,

When the engine is running, do you hear any knocking or ticking from the engine? If there is no pressure, it would likely be making a lot of engine noise. Also, the absence of oil pressure wouldn't cause a whining noise, instead, you would hear a knocking or ticking,

If it is loud enough to record the noise, record it and upload it for me to hear. Also, the oil switch itself may have failed. Under normal conditions, it is an easy thing to replace. However, on this engine, it requires the removal of the intake manifold.

Try to record what you are hearing so I can hear it. I should be able to tell if it lost oil pressure.

Let me know.

Yes, you could have a bad cluster and a clogged oil pump pick up. I would remove the oil pan to inspect the oil pump pickup, also you can try a manual oil pressure gauge which you can rent from the auto parts store to confirm the problem. It is inserted where the oil pressure sender goes. Here is how to remove the oil pan. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.

Anything?
