Hello,

It sounds like you have an issue with your engine bearings, particularly with the big end bearings, please see illustration below.

Please check your oil level, if low first top it up and see if the noise gets better and if the oil pressure light goes off.

Please see links below regarding possible engine noises.

Also see link below on how to check your engine oil level and, if you are able to do so, to check your engine oil pressure.

Please let us know how you get along.

Cheers, Boris

okay, i had my oil change yesterday at Big O Tires then drove 75 miles back home noticed all the issues nd the noise the oil light flashes .
when i checked the oil level it was full but oil was a dark color.
so I'm thinking no oil change was done.

Hi,

If the oil is full, the oil light shouldn't be coming on. To be honest, it sounds like a rod or main bearing. Is there anything that makes it stop?

Based on the sound and the fact the oil pressure light is coming on, I suspect the oil pump has failed. What you could do is check the oil pressure using a mechanical pressure gauge. Most parts stores will lend one to you. Basically, you simply remove the electric oil pressure sensor and screw in the mechanical one. Start the engine and see what the pressure is.

Here is a link you may find of interest:

If the noise is a main bearing or rod bearing, the engine will need to be rebuilt. Actually, you may be better off finding a used engine with low mileage. It likely would be cheaper.

If you want, you could take the oil pump apart and inspect it and rebuild it. However, that will not likely get rid of the noise you hear.

If you look at the attachments below, they include the directions and related pictures for removal, inspection, and replacement of the oil pump.

Let us know.

Take care,

Joe

Hi,

Can you upload a pic of the oil and a video of it running?
