Oil everywhere?

Hey! I was at the exhaust shop, and they put it on the lift to start my installation. So, I decided to look around under the truck and I found that there’s a lot of oil and gunk everywhere. This was yesterday. Today, while driving. My oil pressure would drop to 0 at idle. Like red lights and such and the dash would say check gauges. Is it possible that something’s wrong with the tube and screen? Or maybe the oil pump? I have no idea. My oil level is currently a few inches above the “add” line. No strange sounds or feelings. Last change was 6.5k miles ago. Filter and oil change. Conventional 10w-30. Here’s a video I took while on the lift.

Hi,

What I saw in the video really isn't out of the ordinary for any engine. There is a seal at the front of the crankshaft and the gasket at the front top of the oil pan is known to leak after a vehicle has some miles on them. Based on what I see, I wouldn't be concerned.

Now, the oil light is a different thing. If it was showing no pressure, that is a concern. However, if the gauge went to 0 and there was no ticking or knocking from the engine, there is a chance it is simply the oil pressure switch. Interestingly, when they fail, they can leak oil. LOL So, that may be adding to what you are seeing.

The oil pressure switch is on the top rear of the engine, behind the distributor. See pic 1 below. Check to make sure there are no leaks from that area. Also, make sure the connector to it is in good condition, not damaged, corroded, or loose.

If that checks good, you can get a mechanical oil pressure gauge and remove the electric sensor I mentioned, and screw in the mechanical. That way, you will have a creditable reading as far as pressure. Most parts stores will lend a mechanical gauge to you for testing.

Let me know if this helps. Also, let me know if you have other questions.

Take care,

Joe
