Hello All

I have a Ralliart Sportback and the last day I have noticed a strange sound coming from my engine. I noticed it at increasing rpm when the car would shift gears to a vibrating noise and after letting off the accelerator at mid rpm. I thought it was the heat shield for the turbo since I have cat back exhaust and made sure it was secure and to check to see if the manifold had any cracks. After confirming things were secure and no cracks I started it back up and recorded it. It seems to be dominately heard after letting off the accelerator.

it seems to be coming from the passenger side of the engine. The car has 106k miles and the timing chain was all redone at 99k miles. I haven't had any issues since. Oil was changed a couple hundred miles ago along with the SST fluid.

If I could get some insight on the matter that be very helpful. Have been researching and haven't been able to find something that exactly matches the sound I am experiencing

Thanks
