When oil light turns on there is a loud noise coming from under the hood

Good morning,

You have an oil pressure issue. When the light comes on, the pressure is either low or not there at all. That is the noise. The engine bearings are not being lubricated and the noise is damaging the motor.

At this point, you have damaged the engine driving it this way.

Did anyone do a manual oil pressure test?

Most likely you are going to need the engine replaced.

Can you upload a video of the noise?

The noise isn't there all the time. Once you drive the car awhile that's when the oil light comes on then minutes later the noise under hood.

Can you upload a video for me to view?

What tests have been done for this?

Roy

I just started it and drove it down the street didn't do anything the sound comes and goes but the oil light always comes on first. my engine light is on and had a diagnostic test done said it was my solenoids i replaced those. Also all the spark plugs i just paid someone $500.00 to fix my vehicle go to pick it up and didn't even make it home before it started acting up.

Okay, they have nothing to do with your noise. that is a separate issue.

When it makes the noise, take a video of the noise and upload it to this post for us to hear.

Roy

I will do that thanks.

You are welcome.

Always glad to help.

Roy

This is the sound it makes:

Thank you.

That is an internal engine noise from the bearings and lifters. It comes from the lack of oil pressure.

I would stop driving immediately and have this addressed and repaired before it leaves you stranded and the engine locking up.
