I would try the simple things first. Fresh full synthetic pennzoil 5w-20. And fresh tank of 89. If that doesn't help try some fuel system cleaner. Also check EGR.

My 07 loves 89 and full synthetic. Also I got an engine whining and she just popped an PO406 code. EGR. I deleted it and seems to last twenty to thirty cycles before showing up again. Very similar noise to yours.

Buy a stethoscope and start hitting up the engine, transmission, and any area where you think the sound is coming from.

It's cheap.

Tried the oil change and the higher octane fuel, didnt change the sound. How do I check the EGR? I havent gotten any codes? When the stethescope is used its loudest on the y pipe and can hear it a little on the driver side valve cover.

The egr or Exhaust Gas Recirculation is a small canister on the front of the engine by the intake filter box. Honestly after listening to the video I doubt it is that. Exspecially if you say it is loudest or most definitive by the Y pipe. That being the case, maybe it is the oil pump or something top end. Usually fresh oil would alter the pitch in some way.

This is strange, very strange.

With 30k on that motor I really surprise that it would be a noisy pump, bearing, or anything.

Got me stumped.

Are you able to follow the y-pipe up to the exhaust manifold, especially the driver side? Is it louder there?

Also can you confirm that you have tried the oil pan and transmission oil pan?

What other area's by the engine have you tried?

The sound is loudest on the y pipe, it can also be heard on the drivers side valve cover slightly, at first i thought it was the cats but the dealer claims to have changed them. shop told me that they disconnected the trans and the sound was still present so it would rule out the transmision.

From the what you have described it appears that the issue is between the driver's side cylinder head to the y pipe.

I wouldn't take the dealer's word and I would still check between the y-pipe, including the catalytic converter to the exhaust manifold, etc. If you haven't tried either the oil pan or the transmission oil pan, I would still check it.

I checked the converters and they are new along with the y pipe so that was defiantly changed. The transmission was disconnected from the vehicle and the noise didntchange so that rules out any trans issue, I am really wondering if ts the oil pump making the noise as it gets hot. maybe i will just change that out and see.

Ok let's start over.

When did you first notice the noise? Did something happen or anything unusual happen when it first occurred?
How long has it been?
Has it gotten progressively worse?
Does it always get louder after the car has warmed up?
Has it changed since changing out the the cats and y pipe?

I personally would still check the cat and y-pipe and any work done by someone else. You don't know if they accidentally dropped a bolt or nut into the exhaust system when changing it. Even though it's new, you never know if it could be a bad new y-pipe and cat installed. I would go through the effort to completely rule it out. It shouldn't take much time to do.

I just hate to see you keep throwing money on replacing different parts that aren't solving the problem.

I don't think it's the oil pump only because the oil pump sits in front of your crankshaft and is at the front of the engine (Based on what you said before it sound like it's coming from the floorboard). Look at the big pulley at the bottom for the crankshaft. The oil pump is behind it but in front of the timing chain.
